detailed description

Fig. 1 is a diagram of an application environment in which a data processing method based on Internet Content Adaptation Protocol operates in an embodiment. As shown in FIG. 1 , the application environment includes an ICAP client 110 and an ICAP server 120 , wherein the ICAP client 110 and the ICAP server 120 communicate through a network.

The ICAP client 110 is a client supporting the ICAP protocol, which may be a PC or terminal installed with software supporting the ICAP protocol, or a carrier-class network node device implementing the ICAP protocol, but is not limited thereto. The ICAP client 110 sends a related request message to the ICAP server 120 to acquire related resources for service processing.

The ICAP server 120 can be a server supporting the ICAP protocol, a PC, a terminal, a commercial server installed with software supporting the ICAP protocol, or a carrier-class network node device implementing the ICAP protocol, but is not limited thereto. After the ICAP server 120 performs relevant business processing on the ICAP protocol message sent by the ICAP client 110 , it returns a response message to the ICAP client 110 , carrying the relevant resources required by the ICAP client 110 .

As shown in Figure 2, in one embodiment, a kind of data processing method based on Internet Content Adaptation Protocol is provided, is applied to the ICAP client in the above-mentioned application environment as an example, including the following steps:

Step S210, sending a data cache request to the Internet Content Adaptation Protocol ICAP server, the data cache request includes a cache data description field, so that the ICAP server returns a corresponding cache response according to the data cache request, and the cache response includes a cache data response description field and business data .

Specifically, the ICAP client has a data cache function switch, which can receive the operation or signal of the function switch to enable the data cache function. When the data cache function is turned on, if the preset condition is met, the data cache request is sent to the ICAP server. Preset conditions can be customized as required, for example, the data cache control timer can be started, and when the preset timing time arrives, a data cache request will be automatically sent to the ICAP server. It can also detect the current network status and send a data cache request according to the current network status. For example, when the network is smooth, send a data cache request to cache business data. When the network is congested, the cached business data can be used. The data cache request can also be sent according to the user's trigger, such as setting a virtual key to receive a signal from the user to send the data cache request. The cached data description field is used to describe the business data that needs to be delivered by the ICAP server, so that the ICAP server can obtain the business data that needs to be delivered according to the cached data description field. The content of the cached data description field can be customized according to needs, such as the cached data description field It may include the name of the business data, the start position and end position of the business data, the record number of the business data, etc. After the ICAP server obtains the service data to be delivered, it generates a corresponding cache response, and the cache response includes a cache data response description field and service data. The cached data response description field is used to describe the status and business data of the cached response, which can be customized according to needs. For example, the cached data response description field includes the business data end flag field, indicating whether the cached data has been delivered and whether it is necessary to continue sending the cache data. The caching data response description field may also include the number of times the business data is continuously acquired, and the like. The description field of the cached data response may also include a length field describing the service data, so that the ICAP client may cache the service data according to the description field of the cached data response. It can be understood that before delivering the business data, the business data can be sorted according to preset conditions, for example, the business data can be sorted according to the query popularity to generate a business data record set. Cache data description field, cache data response description field and business data can be stored in extended fields, for example, the extension field X-Record-Set of cache response is used to store business data records.

Step S220, store the business data in the local cache according to the description field of the cached data response.

Specifically, a cache corresponding to the service data may be opened according to the description field of the cache data response, and the service data may be stored in the local cache. It can also be judged according to the description field of the cached data response whether it is necessary to interact with the ICAP server to continue to obtain business data and the number of times to continue to obtain business data. When there is an ICAP service query, according to the ICAP service query request, the service data matching the ICAP service query request can be obtained first from the locally cached service data. Since the service data in the local cache has been pre-stored, if there is a matching It can be used directly, speeding up the acquisition of business data and improving the speed of business response. In one embodiment, the generation strategy of the data cache request and the service data in the local cache can be updated according to the matching usage of the service data in the local cache, so as to improve the utilization rate of the service data in the local cache and save the space of the local cache , such as business data in the local cache that has not been used for a long time can be deleted.

In this embodiment, by sending a data cache request to the Internet Content Adaptation Protocol ICAP server, the data cache request includes a cache data description field, so that the ICAP server returns a corresponding cache response according to the data cache request, and the cache response includes a cache data response description field and business data, save the business data in the local cache according to the cached data response description field. Since the business data in the local cache has been pre-stored, when there is an ICAP service query, you can find the matching business data in the local cache. If there is The matching ones can be used directly, which speeds up the acquisition of business data and improves the speed of business response.

In one embodiment, as shown in Figure 3, a data processing method based on Internet Content Adaptation Protocol is provided, comprising the following steps:

Step S310, sending an option query request to the ICAP server, the option query request includes a client cache data support field, so that the ICAP server returns an option query response according to the client cache data support field, and the option query response includes a server cache data capability field.

Specifically, send an option query request to the ICAP server, which carries the client cache data support field, such as the client cache data support field is an extended field X-Cache-Capability, and the value is 1, indicating that the ICAP client supports the Cache cache function or whether What is its value, as long as there is an extension field X-Cache-Capability, it means that it supports the Cache caching function. The option query request message is to reuse the existing request message of the ICAP protocol, as long as the required extension field is added to the preset position of the existing request message of the ICAP protocol. After the ICAP server receives the option query request, it judges that the option query request carries the client cache data support field, such as the extended field X-Cache-Capability field, then returns the option query response to the ICAP client to carry the server cache data capability field , if the server caching data capability field is the extended field Y-Cache-Capability, it indicates whether the ICAP server supports the Cache caching function, such as a value of 1 means it supports it, and 0 means it does not support it. The option query response message is to reuse the existing response message of the ICAP protocol, as long as the required extension field is added to the preset position of the existing response message of the ICAP protocol.

Step S320, judging whether the server caching data capability field indicates that the ICAP server supports data caching, if yes, proceed to step S330, otherwise, do not process.

Specifically, the ICAP client receives the option query response, and judges the server cache data capability field carried in the option query response, such as whether the extension field Y-Cache-Capability is supported, and if the value of the extension field is 1, it means support, and enters Step S330 sends the data cache request. If the ICAP server does not support data caching, no processing is performed, and a data caching request cannot be sent to the ICAP server. Before sending the data cache request, query whether the ICAP server supports data cache can avoid interference to the ICAP server caused by still sending a data cache request to the ICAP server when the ICAP server does not support data cache.

Step S330, sending a data cache request to the ICAP server, the data cache request includes a cache data description field, so that the ICAP server returns a corresponding cache response according to the data cache request, and the cache response includes a cache data response description field and service data.

Step S340, store the business data in the local cache according to the description field of the cached data response.

In one embodiment, the data cache request is a customized data cache request message or a request message of the multiplexing ICAP protocol, and the cache response is a customized cache response message or a multiplexing ICAP protocol response message, and the data cache request and the cache response message The type is consistent.

Specifically, the customized data cache request or cache response message is in plain text format, and the specific format can be customized as long as the format conforms to the existing ICAP protocol. The data cache request or cache response can also be a request message of the multiplexing ICAP protocol, as long as the required extension field is added to the preset position of the existing request message of the ICAP protocol. The message types of the data cache request and the cache response are consistent. For example, if the data cache request is customized, the cache response is also customized. The message types of the data cache request and the cache response are consistent, which facilitates quick parsing between messages.

In one embodiment, the cache data description field includes a service data request record number field and a service data index field, and the cache data response description field includes a service data response record number field.

Specifically, the business data request record number field is used to describe the number of business data records that need to be delivered in this request. For example, the data cache request carries the extended field X-Record-Number to indicate that the request needs to be delivered by the ICAP server. The number of business data records. The business data index field is used to describe the starting location of the business data that needs to be delivered by the ICAP server in this request. For example, the data cache request carries the extended field X-Record-Index to guide the ICAP server to specify the location from the business data record set. The business data records start to be distributed. Use the business data index field to find the starting position of the business data delivery, and then start from the starting position to find the business data with the same length as the business data described in the business data request record number field, which is the target business data delivered by this request . The business data response record number field is used to describe the number of business data records actually delivered by the ICAP server this time, and the number of business data records actually delivered is less than or equal to the number of business data records to be delivered in this request. The ICAP client can open up a local cache space of a corresponding size according to the field of the number of records in the business data response to cache the business data. If the cached response carries the extended field X-Record-Number, it indicates the record number field of the service data response. The target business data can be quickly obtained through the business data request record number field and the business data index field, and the local cache space can be quickly determined through the business data response record number field.

In one embodiment, the caching data response description field further includes a service data end flag field, and after step S220, further includes: if the business data end flag field is continuing data caching, continuing to send a data caching request to the ICAP server.

Specifically, the service data end flag field is used to describe whether the data cache request has been responded to. For example, the cache response carries the extension field X-Record-Isover. According to the extension field X-Record-Isover in the cache response, it is judged whether to continue with the The ICAP server interacts and asks for business data records. If the value of X-Record-Isover is 1, it means that the interaction needs to be continued, and the value of X-Record-Isover is 0, which means that it is not needed. If the business data end flag field is to continue data caching, that is, X-Record -Isover value is 1, then continue to send a data cache request to the ICAP server, and continue to obtain the service data that needs to be cached, otherwise the cached service data has been obtained this time. Through the service data end flag field, the service data that needs to be cached can be divided into multiple times for delivery, so that the data transmission can adapt to the real-time network situation and improve the flexibility of service data transmission.

In one embodiment, the method further includes: receiving the ICAP service query request, searching the local cache for the service data matched by the ICAP service query request, and using it directly.

Specifically, after receiving the ICAP service query request, the service data that matches the ICAP service query request is preferentially obtained from the locally cached service data. Since the service data in the local cache has been pre-stored, if there is a match, it can be directly The use speeds up the acquisition of business data and improves the speed of business response. If no matching service data is found, a service request message is sent to the ICAP server to obtain matching service data from the ICAP server.

In one embodiment, as shown in FIG. 4 , a data processing method based on the Internet content adaptation protocol is provided, which is illustrated by an ICAP server applied to the above-mentioned application environment, including the following steps:

Step S410, receiving a data caching request sent by an ICAP client, where the data caching request includes a caching data description field.

Specifically, the cached data description field is used to describe the business data that needs to be delivered by the ICAP server. The ICAP server can obtain the business data that needs to be delivered according to the cached data description field. The content of the cached data description field can be customized according to needs, such as cached data The description field may include the name of the business data, the start location and end location of the business data, the record number of the business data, and so on.

Step S420, obtain the corresponding service data according to the data cache request, and return the corresponding cache response, the cache response includes the cache data response description field and business data, so that the ICAP client can store the business data locally according to the cache data response description field cache.

Specifically, after the ICAP server obtains the service data to be delivered according to the data cache request, it generates a corresponding cache response, and the cache response includes a cache data response description field and service data. The cached data response description field is used to describe the status and business data of the cached response, which can be customized according to needs. For example, the cached data response description field includes the business data end flag field, indicating whether the cached data has been delivered and whether it is necessary to continue sending the cache data. The caching data response description field may also include the number of times the business data is continuously acquired, and the like. The description field of the cached data response may also include a length field describing the service data, so that the ICAP client may cache the service data according to the description field of the cached data response. It can be understood that before delivering the business data, the business data can be sorted according to preset conditions, for example, the business data can be sorted according to the query popularity to generate a business data record set. Cache data description field, cache data response description field and business data can be stored in extended fields, for example, the extension field X-Record-Set of cache response is used to store business data records.

After receiving the cached response, the ICAP client can open a cache corresponding to the business data according to the description field of the cached data response, and save the business data in the local cache. It can also be judged according to the description field of the cached data response whether it is necessary to interact with the ICAP server to continue to obtain business data and the number of times to continue to obtain business data. When there is an ICAP service query, according to the ICAP service query request, the service data matching the ICAP service query request can be obtained first from the locally cached service data. Since the service data in the local cache has been pre-stored, if there is a matching It can be used directly, speeding up the acquisition of business data and improving the speed of business response.

In this embodiment, by receiving the data cache request sent by the Internet Content Adaptation Protocol ICAP client, the data cache request includes a cache data description field, obtains the corresponding business data according to the data cache request, and returns the corresponding cache response, and the cache response includes cache The data response description field and the business data, so that the ICAP client stores the business data in the local cache according to the cached data response description field, and the business data in the local cache is used for the ICAP client to search preferentially when performing an ICAP business query And use, can return the corresponding business data that needs to be cached according to the data cache request sent by the ICAP client, so that the ICAP client will cache the received business data, and use it for ICAP business query priority search and use, because the ICAP server has already The business data is sent to the ICAP client in advance and stored in advance. If there is a match, it can be used directly, which speeds up the acquisition of business data and improves the speed of business response.

In one embodiment, before step S410, it also includes: receiving an option query request sent by the ICAP client, the option query request includes a client cache data support field, and returns an option query response according to the client cache data support field, and the option query response includes Server caching data capability field.

Specifically, the client cache data support field is carried in the option query request. For example, the client cache data support field is an extended field X-Cache-Capability with a value of 1, indicating that the ICAP client supports the Cache function, or whatever the value is , as long as there is an extension field X-Cache-Capability, it indicates that the Cache caching function is supported. The option query request message is to reuse the existing request message of the ICAP protocol, as long as the required extension field is added to the preset position of the existing request message of the ICAP protocol. After the ICAP server receives the option query request, it judges that the option query request carries the client cache data support field, such as the extension field X-Cache-Capability with a value of 1 or as long as the X-Cache-Capability field is carried regardless of its value , the option query response returned to the ICAP client carries the server cache data capability field. For example, the server cache data capability field is an extension field Y-Cache-Capability, indicating whether the ICAP server supports the Cache cache function. If the value is 1, it indicates support. 0 means not supported. The option query response message is to reuse the existing response message of the ICAP protocol, as long as the required extension field is added to the preset position of the existing response message of the ICAP protocol. The ICAP client receives the option query response, and judges the server cache data capability field carried in the option query response, such as whether the extension field Y-Cache-Capability is supported, and if the value of the extension field is 1, it means support, and then sends a data cache request , otherwise the data cache request cannot be sent to the ICAP server. For an ICAP server that does not support data caching, it can return a corresponding response that does not support data caching to the query request of the ICAP client, thereby avoiding that when the ICAP server does not support data caching, the ICAP client still sends a data caching request to the ICAP server. Interference with the ICAP server.

In one embodiment, the data cache request is a customized data cache request message or a request message of the multiplexing ICAP protocol, and the cache response is a customized cache response message or a multiplexing ICAP protocol response message, and the data cache request and the cache response message The type is consistent.

Specifically, the customized data cache request or cache response message is in plain text format, and the specific format can be customized as long as the format conforms to the existing ICAP protocol. The data cache request or cache response can also be a request message of the multiplexing ICAP protocol, as long as the required extension field is added to the preset position of the existing request message of the ICAP protocol. The message types of the data cache request and the cache response are consistent. For example, if the data cache request is customized, the cache response is also customized. The message types of the data cache request and the cache response are consistent, which facilitates quick parsing between messages.

In one embodiment, the cache data description field includes a service data request record number field and a service data index field, and the cache data response description field includes a service data response record number field.

Specifically, the business data request record number field is used to describe the number of business data records that need to be delivered in this request. For example, the data cache request carries the extended field X-Record-Number to indicate that the request needs to be delivered by the ICAP server. The number of business data records. The business data index field is used to describe the starting location of the business data that needs to be delivered by the ICAP server in this request. For example, the data cache request carries the extended field X-Record-Index to guide the ICAP server to specify the location from the business data record set. The business data records start to be distributed. Use the business data index field to find the starting position of the business data delivery, and then start from the starting position to find the business data with the same length as the business data described in the business data request record number field, which is the target business data delivered by this request . The business data response record number field is used to describe the number of business data records actually delivered by the ICAP server this time, and the number of business data records actually delivered is less than or equal to the number of business data records to be delivered in this request. The ICAP client can open up a local cache space of a corresponding size according to the field of the number of records in the business data response to cache the business data. If the cached response carries the extended field X-Record-Number, it indicates the record number field of the service data response. The target business data can be quickly obtained through the business data request record number field and the business data index field, and the local cache space can be quickly determined through the business data response record number field.

In one embodiment, the cached data response description field also includes a service data end flag field, and the method further includes: judging whether the service data sent to the ICAP client has been sent, and if not, the service data end flag field is the continuation data cache, otherwise the business data end flag field is the end data cache.

Specifically, the service data end flag field is used to describe whether the response to the data cache request is completed. If the service data sent to the ICAP client is completed, the extended field X-Record-Isover can be carried in the cached response, and its A value of 0 means that no further sending is required. If the business data sent to the ICAP client has not been sent yet, set the value of the extension field X-Record-Isover to 1, indicating that it needs to continue sending. Through the service data end flag field, the service data that needs to be cached can be divided into multiple times for delivery, so that the data transmission can adapt to the real-time network situation and improve the flexibility of service data transmission.
