Description

Method and device for recording instant message reading state

technical field

The invention relates to the technical field of communications, in particular to a method and device for recording instant message reading status.

Background technique

Instant messaging (IM for short) is a terminal service that allows two or more people to use the Internet to transmit text messages, files, voice and video in real time. Instant messaging is different from e-mail in that its conversation is instant, such as commonly used QQ, YY voice, Fetion and so on. When using these instant messaging applications for communication, the information sender needs to know whether the information receiver has read the information, so as to prevent important information from being missed.

The methods for recording the reading status of instant messages in the prior art are mainly divided into the following two categories:

Method 1. Client recording method. After each recipient of the information reads the message, it will relay through the server to notify the sender of the information. At this time, the client of the sender will add a record in the local device to identify who has read the information;

Method 2. Server-side recording method. After each receiver of the information reads the information, it notifies the server. At this time, the server inserts a record into the database to identify who has read the information.

In the process of implementing the embodiments of the present invention, the inventors found that there are at least the following problems in the prior art:

Defect of method 1: After the client is reinstalled, all read and unread information will be cleared; the read and unread information of the same account on different devices are incomplete.

The defect of method 2: when there are a lot of message recipients, such as group chat, the number of recipients of each message may be dozens or even thousands. Each person's reading information inserts a record into the database, and a record needs to store at least one record element {"user_id":int64, "message_id":int64} consisting of the reader's user ID and message ID, at least 16 bytes , as the number of recipients increases, it will bring huge data writing pressure and information storage pressure to the database.

detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

Fig. 1 shows a flowchart of a method for recording instant message reading status according to an embodiment of the present invention. As shown in Figure 1, the method includes the following steps:

Step S101, receiving a message sent from a sending end to a receiving end, and generating a message identifier for the message.

Each time the sender sends a message, it will send data such as sender information, message data, and receiver information to the server, so that the server can query relevant data and forward the instant message.

After receiving data such as sender information, message data, and receiver information, the server will generate a new message record. Each message record has a unique message_id value, which is the message ID, and returns the message ID to the sender. The terminal is used as the basis for the sender to obtain the reading status. At the same time, the message identifier can also be used for querying related data in the data table.

Step S102, generating first bitmap data according to the record of the receiving end, and storing the message identifier and the first bitmap data.

Wherein, the record at the receiving end records the information of the receiver at the receiving end, the first bitmap data corresponds to the message ID, and each message ID has a unique first bitmap data corresponding to it.

Specifically, when the receiver is a receiver, it is a one-to-one private communication mode. In this case, the receiver is specified and selected by the user, so the record of the receiver records the data of the receiver. According to this record , the first bitmap data generated by the server is 0x1; when the receiving end contains multiple receivers, it is a one-to-many communication mode. In this case, each record in the receiving end records the data of one receiver , such as the serial number corresponding to the receiver. When generating the first bitmap data, set the position of the first bitmap data corresponding to the receiver's member serial number to 1, indicating that there is a member at this position. Taking the receiving end as an example with 5 receivers, the member serial numbers in the records of the 5 receivers are 1, 2, 3, 4, and 5 respectively, then the first bitmap data 1 to 5 are all set to 1, so The generated first bitmap data is 0x1F.

Insert the message identifier and the corresponding first bitmap data into the database of the server.

Step S103, sending the message to the receiving end.

The server sends messages carrying information such as message data and message identifiers to all receivers at the receiving end.

Step S104, receiving the message reading notification returned by the receiving end, and modifying the first bitmap data according to the message reading notification to obtain the second bitmap data.

After the receiving end receives the message sent by the server, if the corresponding member reads the message, it will return the message reading notification to the server. The message reading notification includes the member serial number and message ID of the corresponding receiver at the receiving end. The member serial number is numbered from 1, and each receiver corresponds to a unique serial number, which is neither repeated nor spaced. For example, if there are 100 receivers at the receiving end, then the serial numbers of these 100 receivers are 1, 2, 3... 100.

Assuming that the member serial number of the recipient in the message reading notification received by the server is 3, the third bit of the first bitmap data is changed to 0, therefore, the first bitmap data 0x1F of the original 5 recipients is replaced by Change it to 0x1B, and the modified bitmap data is called the second bitmap data; similarly, if only the receiver member whose member serial number is 3 does not return a message reading notification, the first bitmap data only has the 3rd bit It is not modified to 0, therefore, the second bitmap data obtained after modification is 0x4.

The above operation of modifying the corresponding bit of the first bitmap data to 0 is implemented by performing a bitwise AND operation between the value of the corresponding bit and 0.

Step S105: Return the reading status of the message to the sender according to the second bitmap data.

After the bits of the first bitmap data corresponding to the receiver member serial numbers corresponding to all the message reading notifications are modified, the obtained bitmap data is called the second bitmap data, and each bitmap data of the second bitmap data The bit indicates the reading status of a receiver. Specifically, if it is 0, it means that the receiver corresponding to this bit has read the message, and if it is 1, it means that the receiver corresponding to this bit has not read the message.

If the sending end wants to know the reading status of the members of the receiving end, the server can query the second bitmap data according to the correspondence between the message identifier and the second bitmap data by providing the message identifier to the server, and return the first bitmap data Send the bitmap data to the sending end, and the sending end can know the reading status of the receiver at the receiving end; or, the server directly transmits the reading status of the receiving end to the sending end.

Next, taking the private communication mode in which the receiving end is one receiver as an example, the specific implementation of the above steps S101 to S105 will be described:

In step S101, the sender A sends a message to the receiver B, and after receiving the information of the sender A, the message data, and the information of the receiver B, the server generates a message identifier mid1 for the message, and returns the message identifier mid1 to the sender a.

In step S102, the record of the receiver has a data record of receiver B, according to this record, the first bitmap data rs1 generated by the server is 0x1, and the generated message identifier mid1 and the first bitmap data rs1 are inserted into the database middle.

In step S103, the server sends to the receiver B a message carrying information such as message data and message identifier mid1.

In step S104, after receiving the message, the receiver B returns a message reading notification to the server, including the information of the sender A and the message identifier mid1, and sets the position where the first bitmap data rs1 is 1 to 0, which is recorded as the second Bitmap data rs2; if receiver B does not return a message read notification, the method terminates.

In step S105, after obtaining the second bitmap data rs2, the server can directly return the reading status of the receiver B to the sender A; or, the sender A obtains the received information by providing the message identifier mid1 to the server. Reader B's reading status. The above read status is the 0 or 1 value of the corresponding bit of the second bitmap data rs2. If it is 0, it means that the message mid1 has been read by the receiver B; if it is 1, it means that the message mid1 has not been read by the receiver B.

According to the recording method of the instant message reading state provided by this embodiment, after receiving the message sent by the sending end, generate the first bitmap data according to the record of the receiving end; after receiving the message reading notification returned by the receiving end, read the The notification modifies the first bitmap data to obtain the second bitmap data, and the second bitmap data records the reading status of the instant message, so as to return the reading status of the message to the sending end. The present invention uses a bitmap to record the reading state of each receiving end, and compresses the record of the reading state of each receiving end into 1 bit, which greatly saves the data storage space compared with a record occupying at least 16 bytes in the prior art, thus It solves the problem of bringing huge data writing pressure and information storage pressure to the database.

The present invention records the reading state of the receiver through a bitmap, and compresses the record of each receiver to 1 bit, which solves the problem of huge data writing pressure and information storage pressure on the database, and saves data storage space beneficial effect. Especially when the receiving end has a large number of group members, the effect obtained by using the present invention for recording is more obvious.

Before the preferred embodiment of the present invention is implemented, the record and query of the implementation process are simplified by setting up a reasonable data structure model. The data structure model established by the present invention has information data table model (message_t), group member data table model ( qun_member_t) and information-related group member snapshot data table model (qun_snapshot_t).

a. The main fields of the information data table model (message_t) are shown in Table 1:

Table 1 Information data table message_t main fields

field name Field Type message_id int64 read_status bitmap

message_id: Every time a message is sent, the server will generate a new message record. Each message record has a unique corresponding message_id value, which is the message ID, and the message_id value is strictly monotonically increasing, that is, the message id of the message sent later Will be greater than the value sent first.

read_status: Indicates the reading status of the message read by the receiver. When the read_status bitmap value is all 0, it means that all receivers have read it, otherwise it means that some receivers have read it or no one has read it.

b. See Table 2 for the main fields of the group member data table model (qun_member_t):

Table 2 The main fields of the group member data table qun_member_t

field name Field Type qun_id int64 member_seq int64

qun_id: Whenever a user creates a new group, the server will generate a new group id, that is, the group ID. The group id values of different groups are strictly monotonically increasing, that is, the group of the group created later The group id will be greater than the group id value of the first created group.

member_seq: Whenever a new group member is added to the group, the server will generate a new member_seq value under the qun_id corresponding to the group, which is the member sequence number corresponding to the group member. When the qun_id value is the same, the member_seq value is strictly monotonically increasing and continuous. That is, if there is a group with the qun_id value of 1, the member_seq value of the first member who joins the group is 1, and the member_seq value of the second member is 2, and so on.

c. The main fields of the information-related group member snapshot data table model (qun_snapshot_t):

Table 3 Group member snapshot data table qun_snapshot_t main fields

qun_id: corresponds to the value of the qun_id field in qun_member_t

message_id: corresponds to the message_id field value in message_t

member_bitmap: group member snapshot bitmap, whenever there is a change in the number of members of the group, a group member snapshot record will be added to the table, the xth bit of the bitmap in member_bitmap is 0, and the value of member_seq The member whose value is x is still in the group, otherwise it means that the member has left the group.

Fig. 2 shows a flowchart of a method for recording instant message reading status according to another embodiment of the present invention. This method is aimed at the situation that the receiving end is a group member, that is, multiple recipients at the receiving end are in the same group, as shown in Figure 2, this method includes the following steps:

Step S201, receiving a message sent from a sending end to a receiving end, and generating a message identifier for the message.

After receiving the message data sent by the sender, the server will generate a new message record, and each message record has a unique corresponding message_id value, that is, the message identifier.

Step S202, querying the records of valid members in the group according to the group ID.

Query the group member data table qun_member_t according to the group identifier qun_id value corresponding to the group that sent the message, and obtain the record of the effective member in the group when the message was sent. The record of the effective member is the record of the member who has not left the group.

Assuming that the value of the group identifier qun_id is 1, the effective member records obtained by querying the group member data table qun_member_t are:

[{"qun_id":1,"member_seq":1},{"qun_id":1,"member_seq":2},...,]

{"qun_id":1, "member_seq":1} is the first record, {"qun_id":1, "member_seq":2} is the second record.

Step S203, query the member serial numbers corresponding to valid members in the group.

According to the records of valid members, the member serial number of the valid members recorded in each record can be obtained. For example, the record {"qun_id":1, "member_seq":4} indicates that the valid member in the group corresponds to the member sequence number 4.

Step S204, setting the data at the position corresponding to the member serial number corresponding to the valid member in the group in the bitmap as the first data, and obtaining the first bitmap data.

Among them, each bit value of the first bitmap data indicates whether the member corresponding to the member serial number in the group is valid, if it is 1, it means that the corresponding member is a valid member, that is, the member is still in the group; if it is 0, it means that the corresponding member is an invalid member, that is, the member has withdrawn from the group. The first bitmap data corresponds to the message ID, and each message ID has a unique first bitmap data corresponding to it.

After querying the member sequence number member_seq corresponding to the valid members in the group, set the corresponding member_seq bit in the first bitmap data read_status to 1.

For example: the member sequence number msx of the effective member recorded in the first record is 3, then the third bit of the first bitmap data rs1 is set to 1, that is, rs1 is 0x4; the member sequence of the effective member recorded in the second record number msx is 5, then the fifth bit of the first bitmap data rs1 is set to 1, that is, rs1 is 0x14... and the data at the corresponding position of the member serial number msx corresponding to the valid member in the first bitmap data rs1 is set as The first data, the first bitmap data rs1 is obtained.

It can be seen that the specific operation of generating the first bitmap data read_status from the records of group members is to query the records of valid members in the group according to the group identifier qun_id, and generate the first bitmap data according to the valid members in the group.

Step S205, storing the message ID and the first bitmap data.

Insert the message identifier message_id and the corresponding first bitmap data read_status into the database of the server.

Step S206, sending the message to the receiving end.

The server sends a message carrying information such as message data, member sequence number member_seq, and message identifier message_id to all group members at the receiving end.

Step S207, receiving the message reading notification returned by the group members.

For the case that the group member corresponding to the receiving end is a valid member, there are two reading states: read and unread. After the receiving end receives the message sent by the server, if the group members at the receiving end have read the message, the message reading notification will be returned to the server.

Step S208, according to the message reading notification, determine the member sequence numbers corresponding to the group members who return the message reading notification.

The message reading notification includes the member sequence number member_seq and the message identifier message_id, that is, the member returning the message reading notification should return the message identifier message_id corresponding to the read message and the member's member sequence number member_seq to the server. According to the member sequence number member_seq of the returned message reading notification, it can be determined which members have read status as read.

Step S209, setting the data at the position corresponding to the member serial number corresponding to the group member who returns the message reading notification in the bitmap corresponding to the first bitmap data as the second data, to obtain the second bitmap data.

The server queries the information data table message_t according to the value of the member sequence number member_seq and the message identifier message_id in the message reading notification, and sets the bit of the corresponding member sequence number member_seq of the first bitmap data to 0, and the step of setting it to 0 adopts The value of the corresponding bit is ANDed with 0, and the set first bitmap data read_status is called the second bitmap data read_status.

Step S210, according to the group identifier and the message identifier, the snapshot bitmap data of the group members is acquired, and the snapshot bitmap data of the group members is set according to the snapshot records of the members who have not left the group and the members who have left the group.

Query the group member snapshot data table qun_snapshot_t according to the group identifier qun_id and the message identifier message_id, and obtain the corresponding group member snapshot bitmap data member_bitmap.

Among them, the group member snapshot bitmap data member_bitmap is set according to the snapshot records of the members who have not left the group and the members who have left the group. Add a snapshot record to the data table qun_snapshot_t. The value of the bit corresponding to the member sequence number member_seq in the group member snapshot bitmap data member_bitmap is 0, indicating that the member corresponding to the member sequence number member_seq is still in the group, otherwise, it indicates that the member has left the group.

Taking the original 10 group members in the group as an example, two group members with member serial numbers msx of 3 and 5 quit the group halfway, then the 3rd and 5th digits of the latest group member snapshot bitmap data mb1 The value is 1, and the value of other bits is 0, that is, the group member snapshot bitmap data mb1 is 0x14.

Step S211, perform a bitwise operation on the group member snapshot bitmap data and the second bitmap data to obtain the third bitmap data used to record the reading status of the group members; traverse the third bitmap data, and return the information of the message to the sender Read status.

A certain bit of the second bitmap data read_status has a value of 0 in two situations: the group member corresponding to this bit has read the message corresponding to the message identifier message_id and the group member corresponding to this bit has left the group.

Therefore, it is impossible to directly determine which group members have read the message corresponding to the message identifier message_id. The embodiment of the present invention adopts the method of bitwise XORing the second bitmap data read_status and the group member snapshot bitmap data member_bitmap to obtain the third bitmap data bitmap, so that the value of the bit corresponding to the retired member in the second bitmap data read_status that is 0 can be set to 1, so that the sender can know which members have read the message corresponding to the message identifier message_id.

Continuing the example of the original 10 group members in the above group, the invalid members in the group are the members whose member sequence numbers msx are 3 and 5, and the third and fifth positions of the first bitmap data rs1 can be obtained as 0 , and the other bits are 1, so the first bitmap data rs1 is 0x3EB; assuming that the member serial number msx of the member returning the message reading notification is 1, 2, 4, 6, 7, 9 and 10, then the first bitmap data rs1 On the basis of , perform a bitwise AND operation on the values except the 1st, 2nd, 4th, 6th, 7th, 9th and 10th bits and 0, and the modified second bitmap data rs2 is 0x80. Only the 8th bit of the second bitmap data rs2 is 1, but actually the members whose member serial numbers msx are 3 and 5 do not return message notifications, so adopt the method of this embodiment to convert the second bitmap data rs2 Perform a bitwise XOR operation with the group member snapshot bitmap data mb1 of 0x14 to obtain the third bitmap data mp1 of 0x94, that is, the values of the 1st, 2nd, 4th, 6th, 7th, 9th and 10th bits are 0, indicating the corresponding Members with member serial numbers msx of 1, 2, 4, 6, 7, 9 and 10 returned message read notifications.

It can be seen that, through each bit of the obtained third bitmap data bitmap, the message reading status of each member can be known.

According to the recording method of the instant message reading state provided by this embodiment, after receiving the message sent by the sending end, generate the first bitmap data according to the record of the receiving end; after receiving the message reading notification returned by the receiving end, read the The notification modifies the first bitmap data to obtain the second bitmap data, and the second bitmap data records the reading status of the instant message, so as to return the reading status of the message to the sending end. The present invention uses a bitmap to record the reading state of each receiving end, and compresses the record of the reading state of each receiving end into 1 bit, which greatly saves the data storage space compared with a record occupying at least 16 bytes in the prior art, thus It solves the problem of huge data writing pressure and information storage pressure on the database; by obtaining the snapshot bitmap data of group members, confirm the valid members in the group, and use the third bitmap data to read The status and the reading status of valid members are distinguished, so that the sender can directly judge the members who have read the message through the third bitmap data, without referring to other information, making the way for the sender to obtain the reading status simpler.

Fig. 3 shows a functional block diagram of an apparatus for recording instant message reading status according to an embodiment of the present invention.

The returning module 350 is configured to return the reading status of the message to the sending end according to the second bitmap data.

After the bits of the first bitmap data corresponding to the receiver member serial numbers corresponding to all the message reading notifications are modified, the obtained bitmap data is called the second bitmap data, and each bitmap data of the second bitmap data The bit indicates the reading status of a receiver. Specifically, if it is 0, it means that the receiver corresponding to this bit has read the message, and if it is 1, it means that the receiver corresponding to this bit has not read the message.

According to the recording device of the instant message reading state provided by this embodiment, after receiving the message sent by the sending end, the first bitmap data is generated according to the record of the receiving end; The notification modifies the first bitmap data to obtain the second bitmap data, and the second bitmap data records the reading status of the instant message, so as to return the reading status of the message to the sending end.

After the receiving end receives the message sent by the server, if the group members at the receiving end have read the message, the message reading notification will be returned to the server.

The determining unit 412 is configured to determine, according to the message reading notification, the member sequence numbers corresponding to the group members who return the message reading notification.

The message reading notification includes the member sequence number member_seq and the message identifier message_id, that is, the member returning the message reading notification should return the message identifier message_id corresponding to the read message and the member's member sequence number member_seq to the server. According to the member sequence number member_seq of the returned message reading notification, it can be determined which members have read status as read.

The setting unit 413 is configured to set the data in the bitmap corresponding to the first bitmap data at the position corresponding to the member serial number corresponding to the group member who returned the message reading notification as the second data, so as to obtain the second bitmap data.

The server queries the information data table message_t according to the value of the member sequence number member_seq and the message identifier message_id in the message reading notification, and sets the bit of the first bitmap data corresponding to the member sequence number member_seq to 0. The step of setting it to 0 adopts the corresponding The value of the bit is ANDed with 0, and the first bitmap data after setting is recorded as read_status, which is called the second bitmap data read_status.

The obtaining module 420 is used to obtain the group member snapshot bitmap data according to the group ID and the message ID, and the group member snapshot bitmap data is set according to the snapshot records of the members who have not left the group and the members who have left the group.

Query the group member snapshot data table qun_snapshot_t according to the group identifier qun_id and the message identifier message_id, and obtain the corresponding group member snapshot bitmap data member_bitmap.

Among them, the group member snapshot bitmap data member_bitmap is set according to the snapshot records of the members who have not left the group and the members who have left the group. Add a snapshot record to the data table qun_snapshot_t. The value of the bit corresponding to the member sequence number member_seq in the group member snapshot bitmap data member_bitmap is 0, indicating that the member corresponding to the member sequence number member_seq is still in the group, otherwise, it indicates that the member has left the group.

The operation module 430 is configured to perform a bitwise operation on the group member snapshot bitmap data and the second bitmap data to obtain the third bitmap data used to record the reading status of the group members.

A certain bit of the second bitmap data read_status has a value of 0 in two situations: the group member corresponding to this bit has read the message corresponding to the message identifier message_id and the group member corresponding to this bit has left the group.

Therefore, it is impossible to directly determine which group members have read the message corresponding to the message identifier message_id. The embodiment of the present invention adopts the method of bitwise XORing the second bitmap data read_status and the group member snapshot bitmap data member_bitmap to obtain the third bitmap data bitmap, so that the value of the bit corresponding to the retired member in the second bitmap data read_status that is 0 can be set to 1, so that the sender can know which members have read the message corresponding to the message identifier message_id.

The return module 350 is configured to traverse the third bitmap data and return the reading status of the message to the sender.

Each bit of the third bitmap data bitmap represents the reading status of the member corresponding to the member serial number, and the third bitmap data bitmap is returned to the sender, and the sender can know the message reading status of each member.

According to the recording device of the instant message reading state provided by this embodiment, after receiving the message sent by the sending end, the first bitmap data is generated according to the record of the receiving end; The notification modifies the first bitmap data to obtain the second bitmap data, and the second bitmap data records the reading status of the instant message, so as to return the reading status of the message to the sending end. The present invention uses a bitmap to record the reading state of each receiving end, and compresses the record of the reading state of each receiving end into 1 bit, which greatly saves the data storage space compared with a record occupying at least 16 bytes in the prior art, thus It solves the problem of huge data writing pressure and information storage pressure on the database; by obtaining the snapshot bitmap data of group members, confirm the valid members in the group, and use the third bitmap data to read The status and the reading status of valid members are distinguished, so that the sender can directly judge the members who have read the message through the third bitmap data, without referring to other information, making the way for the sender to obtain the reading status simpler. .
