The following detailed description of the more specific implementation process is divided into two aspects: one aspect is an instant message file sending process based on the presence of file fingerprint information, and another aspect is an instant message file sending process based on the absence of file fingerprint information.
Fig. 7 is a schematic diagram of an instant message file sending process based on file fingerprint information, where a scenario is that a user a sends a file message to a user B, and the process involves an instant message client (i.e., a first instant message client), an instant message service end and an instant message client (i.e., a second instant message client) used by the user a, and the specific process includes:
step 1: user a uses the instant messaging client to select a file (represented using file 1) to send to user B and sends it through the instant messaging client a's human machine interface.
Step 2: the instant messaging client (denoted as instant messaging client a) used by user a generates fingerprint information (denoted as signature 1) for file1, signature1 being generated using existing techniques, such as the MD5 algorithm.
And step 3: the instant message client a sends a signature1 to the instant message server along with the destination address of the file message (the destination address in this scenario is the address of user B). The purpose of this step is: the instant message client a sends signalute 1 to the instant message server for detecting whether the instant message server already has files with the same content, and if the instant message server already has files with the same content, the instant message client a may not need to upload the files with the same content to the instant message server. The method avoids the redundant files with the same content stored by the instant message server side, wastes the storage space of the instant message server side, and saves the step of uploading the files by the instant message client side A, thereby obviously shortening the time of sending the file messages for large files and saving the network flow of users.
And 4, step 4: the instant message server searches the file address (the address is represented by fileUrl1) corresponding to the signature1 according to the signature 1. storage and retrieval of the signature1 and the fileuirl 1 are realized by a database technology, and the scheme adopts a MySq1 database.
And 5: the instant messaging service sends the file information (including the most important fileUrl1 in the file information) to the instant messaging client (denoted as instant messaging client B) used by user B.
Step 6: and after receiving the file information, the instant message client B returns a message of successful receiving to the instant message server.
Step 6.1: the instant message client B displays the file information to the user B.
And 7: the instant message server returns fileUrl1 and a result message of successful file transmission to the instant message client A.
And 8: the instant message client a presents the results to the user a.
On the other hand, as shown in fig. 8, it is a schematic diagram of an instant messaging file sending process based on absence of file fingerprint information, where a scenario is that a user a sends a file message to a user B, and the instant messaging client (i.e. a first instant messaging client) used by the user a, an instant messaging service end, and an instant messaging client (i.e. a second instant messaging client) used by the user B are involved, and the specific process is as follows:
step 1: user a uses the instant messaging client (represented by instant messaging client a) to select a file (represented by file 2) to be sent to user B and sends it through the human machine interface of instant messaging client a.
Step 2: the instant messaging client a generates fingerprint information (denoted using signature 2) for file2, and signature2 is generated using existing techniques, such as the MD5 algorithm.
And step 3: the instant message client a sends a signature2 to the instant message server along with the destination address of the file message (the destination address in this scenario is the address of user B).
And 4, step 4: and the instant message server side searches the address of the file2 to be null according to the signature 2. The address being null indicates that the instant message server does not save the same file as the file 2. In the subsequent flow, the instant messaging client a is required to upload the file2 to the instant messaging server.
And 5: the instant message server side returns the result that the signature2 does not exist in the instant message client side A.
Step 6: and the instant message client A uploads the file2 according to the result returned in the step 5.
And 7: the instant message server saves the file uploaded in the step 6 and generates a download address fileUrl2 of the file, and in addition, the instant message server stores the contents of the signature2 and the fileUrl2 and the corresponding relation of the two into a database. When another user sends file2 again through the instant messaging client, the instant messaging server can search for file Url2 according to the signature2 uploaded by the instant messaging client because the file2, the file Url2 and the signature2 are already stored, and the client does not need to upload file2 any more.
And 8: the instant messaging service sends the file information (including the most important fileUrl2 in the file information) to user B's instant messaging client (represented using instant messaging client B).
And step 9: and after receiving the file information, the instant message client B returns a message of successful receiving to the instant message server.
Step 9.1: the instant message client B displays the file information to the user B.
Step 10: the instant message server returns fileUrl2 and a result message of successful file transmission to the instant message client A.
Step 11: the instant message client a presents the results to the user a.

the query judging module is used for querying in the stored files according to the received fingerprint information and judging whether the stored files have the stored files with the same content as the target file;
the first sending module is used for sending first file information to a second instant message client when a storage file with the same content as the target file exists, wherein the first file information comprises a first download address, and the first download address is the download address of the storage file with the same content;
wherein the second instant messaging client comprises:
the third receiving module is used for receiving the first file information;
the first result returning module is configured to return a message of successful receiving to the instant message server after the first file information is successfully received;
and when the instant message server receives the returned information of successful reception, the message of successful reception and the first download address are returned to the first instant message client.
8. The instant message processing system of claim 7 wherein the first instant message client further comprises:
the uploading module is configured to upload the target file to the instant message server when the instant message server does not have the stored file with the same content as the target file;
the instant message service terminal further comprises:
the second receiving module is used for receiving and storing the uploaded target file and storing the fingerprint information of the target file at the same time;
the generation module is used for generating a second download address, wherein the second download address is the download address of the stored target file;
the second sending module is used for sending second file information to a second instant message client, wherein the second file information comprises the second download address;
