Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

FIG. 1 is a flowchart of a method for sharing network comment information according to an embodiment of the present invention.

It includes, step 101, determining the unique identifiers of comment objects located in multiple client servers.

Step 102, embedding a review unit having the unique identifier and one-to-one correspondence with the review objects in the client server.

Step 103, after the user terminal inputs comment content to the comment object of the client server, the comment unit sends the comment content and the unique identifier back to the background database server.

Step 104, the background database server stores the comment content in a database according to the unique identifier.

Wherein, the client server may be a server of a different network service provider, the comment object includes data content such as pictures, text and video, and the comment content includes data content such as text, picture and video.

In the step 101, it further includes: performing data analysis on the client server comment object, obtaining the feature value of the comment object, and according to the feature value of the comment object, assigning all client servers with the feature value The same unique identifier of the comment object, for example, can use the URL address as the feature value of the comment object according to the uniform resource locator address (Uniform/Universal Resource Locator, URL) of the comment object of the client server, as All the comment objects of the client server that reference the URL address, that is, the comment objects with the same characteristic value are given the same unique identifier; if the comment objects are in text format, the text content can also be analyzed, and the text content can be used as the The feature value of the comment object is given the same unique identifier for the comment objects in all client servers of the same text content; if the comment object is a picture, the fifth version of the message digest algorithm of the picture can also be calculated ( Message Digest Algorithm, MD5) value, using the MD5 value as the characteristic value of the comment object, giving the same unique identifier to the comment objects in all client servers with the same MD5 value, wherein the MD5 value is only for example, It should not be a limitation to the embodiments of the present invention; if the comment object is a video stream, the code stream data in the video stream can also be analyzed, and the code stream data can be used as the feature value of the comment object (the The code stream data can be a part of the code stream in the video stream or the entire code stream), and the comment objects in the client server with the same code stream data are given the same unique identifier, and the code stream data can be partly or completely identical . The unique identifier may be a character string or a numeric string composed of numbers.

According to the URL address of the comment object of the client server, using the URL address as the characteristic value of the comment object further includes, if a plurality of comment objects in the client server have the same URL address, they will be the same Different comment objects in the URL address are identified as different sub-characteristic values, the URL address characteristic value of the comment object and the sub-characteristic value of the comment object are combined, and given to the comment objects of all client servers with the characteristic value and sub-characteristic value the same unique identifier.

In addition, in step 101, it may also include, when the characteristic values of the comment objects of different client servers are the same, notify the client server, and according to the response of the client server, give the comment objects with the same characteristic value the same unique identifier, or assign different unique identifiers to review objects with the same feature value. For example, when there is the same comment object (picture) in client server A, client server B, client server C, and client server D, notify the above-mentioned client server A to client server D, according to the response information of the client server , the same unique identifier can be assigned to the pictures specified in client server A, client server B, and client server C, and another unique identifier can be assigned to client server D.

In the step 101, it further includes, receiving an instruction from the client server, assigning a unique identifier to the comment object specified by the specific client server, for example, the unique identifier of the client server A instruction comment object A' is 0001, the client server B instructs the unique identifier of the comment object B' to be 0002.

In the step 103, it is further included that after the user terminal inputs the comment content to the comment object of the client server, the comment unit also obtains the user information currently inputting the comment content, and transmits the user information to the background The database server, for example, can obtain the user name in the cache of the web page browsed by the user terminal, and transmit the user information including the user name and other information to the back-end database server, so that the user can find all related information based on the user information when managing the personal account. related comments.

After the step 104, it further includes that when the user terminal requests to display the comment content of the comment object, the comment unit sends request information carrying a unique identifier to the background database server, and the background database server according to the The unique identifier is matched to the corresponding comment content in the database, and the comment content is sent to the user terminal through the comment unit.

Through the above-mentioned embodiments of the present invention, comments on different websites can be shared through the comment unit, and no matter what client server (the comment unit is installed) the user browses the comment content or comments on the comment object, all can be obtained simultaneously. For the comment content of the same comment object, the information redundancy in the network is saved, and the repeated storage of similar and repeated comment content by different client servers is reduced.
