Description

File transmission processing method and related equipment

Technical Field

The present invention relates to the field of communications, and in particular, to a method and a related device for processing file transmission.

Background

File transfer (file transfer) is the transfer of a file or a portion thereof from one computer system to another, and the transfer of files over a network by a user is a common operation in work and life. The file is usually transmitted by mail, Instant Messaging (IM) software, network disk, etc. However, some troubles may also occur when the user receives the transmission file. For example, a large compressed file is downloaded, and after downloading, the file is opened to find the content which is not needed by the user, which wastes a lot of time for the user. Some malicious users may also disguise executable files such as viruses or trojans as pictures or documents, and induce the users to download the executable files to spread the virus files.

In order to solve the above problems, the following two methods are generally included: (1) the mailbox provides a virus detection function and can detect the mail attachment. (2) The mailbox or the network disk provides the document preview capability, namely the transmitted file is analyzed through the server, and the preview content of the file is displayed in a webpage form.

In the method, the virus detection function provided by the mail has a certain hysteresis, and in the method 1 or the method 2, the analysis of the transmission file by the server is relied on, and when a large number of users upload the file in the same time period, the analysis pressure of the server is relatively high, and the operation speed of the server is influenced.

The communication system can be applied to the application scene of instant messaging transmission files. For example, instant messaging of files is performed through a social application such as QQ, 263. But also to non-instant messaging application scenarios. For example, files are transferred by mail, web disk, etc. For different transmission modes, the server may be a server corresponding to the transmission modes of different files, for example, the server may be a QQ server, may be a wechat server, or the like. The server is illustrative only and not limiting.

In the embodiment of the invention, if the sender needs to transmit the file to the receiving method. The sender analyzes the file, and obtains basic information and preview information of the file to be transmitted through analysis, wherein the basic information is used for describing the file, and the preview information can be partial information of the file. The basic information includes a feature value of a file, where the feature value may be a character string generated for the file when a sender parses the file, and the feature value is used to mark the file, and preferably, the feature value may be a Message-Digest Algorithm (MD 5) value, or may also be an SHA value, RIPEMD, Haval, or the like. In the embodiment of the present invention, the characteristic value may be described by taking the MD5 value as an example. The sender needs to send the transmission request of the file and the basic information of the file to the server first, and the server forwards the transmission request of the file and the basic information to the receiver. The file transmission request is used for instructing the receiver to receive the basic information so that the receiver can obtain the preview information from the server through the characteristic value. And in the file transmission process, providing a file preview service for a user.

Referring to fig. 2, an embodiment of a method for processing file transmission according to the present invention includes:

step 201, the sender determines the file to be transmitted.

The file can be a document file such as Word, PDF, Photoshop, Excel, PPT, AutoCAD, or the like, or the file can also be a multimedia file such as a picture, audio, video, or the like.

In the embodiment of the present invention, the file is described as a PDF file by way of example, but the file is not limited thereto. For example, a user a wants to send a paper document to a user B, and sends the paper document to the user B through the instant messaging of QQ, where the paper document is in PDF format, it should be noted that a first terminal of the user a is a sender, and a second terminal of the user B is a receiver.

Step 202, analyzing the file to obtain basic information and preview information of the file, wherein the basic information includes a characteristic value of the file.

The sender may analyze the file to obtain the basic information and the preview information of the transmission file at the same time, or the sender may analyze the file to obtain the basic information of the transmission file, and then continue analyzing the file to obtain the preview information of the file.

Specifically, the basic information is used to describe the file, please refer to fig. 3a and fig. 3b for understanding, and fig. 3a and fig. 3b are sample diagrams of the basic information. The basic information may include: file name, file type, file size, a characteristic value of the file (e.g., MD5 value), a thumbnail of the file, and the like. In a possible implementation manner, different file types are used to analyze the file, the basic information may also be different, and the basic information for document information such as Word, Excel, PPT, and the like may further include: title, author, abstract, etc. The basic information for audio, video, etc. files may also include: author, title, album, artist, etc. The basic information for the executable file may further include issuer information, version information. Other basic information may also be included for other files. Optionally, the file type may be identified by a file header, so as to avoid disguising the executable file by the file extension. The content included in the basic information may be different according to different file types, and the content included in the basic information is only illustrated in the embodiment of the present invention, and is not limited to the illustration.

The preview information may be partial information of the file or may be summary information of the file. The following lists the preview information of common files, for example:

please refer to fig. 3c, in which fig. 3c is a sample diagram of preview information of a document file. If the document is a document file such as Word, Excel, PPT, PDF, etc., the preview information may be a text summary of the previous M pages, where M is a positive integer.

Please refer to fig. 3d for understanding, fig. 3d is a sample diagram of preview information of a picture file. If the file is a picture file, the preview information may be a thumbnail of the picture. The thumbnail is a small picture obtained by compressing the picture.

Please refer to fig. 3e for understanding, fig. 3e is a sample diagram of preview information of a video file. If the file is a video file, the preview information of the video file may be thumbnails of N images corresponding to different times, where M is a positive integer.

Please refer to fig. 3f for understanding, fig. 3f is a sample diagram of preview information of a design document. If the file is a design document such as Photoshop, the preview information is a thumbnail of the design document.

Please refer to fig. 3g for understanding, fig. 3g is a sample diagram of preview information of the compressed package file. If the file is a compressed package file such as Zip, the preview information is a file directory of the compressed package file. Optionally, the preview information may further include a prompt message indicating whether a password is required.

Please refer to fig. 3f for understanding, fig. 3f is a sample diagram of preview information of an audio file. If the file is an audio file, the preview information is a thumbnail of an album cover of the audio file, and optionally, lyrics are included.

For example, the first terminal of the user a parses the PDF file through the QQ to obtain the basic information of the file, where the basic information of the file includes:

the file type: PDF.

The file size is as follows: 7.07 MB.

MD5 value: 38b8c2c1093dd 0. It should be noted that the file type, file size, and MD5 value are only examples and are not limiting.

The preview information of the file includes: summary information of the first 4 pages of the PDF file. Summary information of the first 4 pages of the PDF file is shown in table 1 below:

TABLE 1

1	Topic of thesis
		2	Full text abstract
3	Paper architecture and directory
		4	Main contents per chapter

Step 203, the sender sends the preview information to the server;

for example, the first terminal of user a sends the preview information in table 1 above to the server.

And step 204, the sender sends the transmission request of the file and the basic information of the file to the receiver.

Specifically, the sender sends a transmission request of the file and basic information of the file to the server, and the server sends the transmission request and the basic information to the receiver.

For example, the first terminal of the user a sends the transmission request of the PDF file and the basic information of the PDF file to the server through the QQ, and the server sends the transmission request of the PDF file and the basic information of the PDF file to the second terminal of the user B.

For example, the QQ of the second terminal receives the basic information according to the transmission request, and the second terminal presents the basic information of the PDF file to the user through the application interface of the QQ, so that the user B can see the file type and the file size of the file. User B wishes to see preview information for the PDF.

Step 205, receiving a characteristic value of a file sent to a server by a receiver;

for example, the second terminal of user B sends the MD5 value for the file to the server.

Step 206, the server receives the feature value of the file sent by the receiver, and determines the preview information matched with the feature value.

Note that the feature value of the file is used to index the preview information of the file, for example, the feature value is described by taking MD5 as an example,

the server receives the MD5 value of the PDF file sent by the second terminal of the user B, at this time, a plurality of pieces of preview information may be cached in the server, and the server determines the preview information which is matched with the MD5 value in the plurality of pieces of preview information according to the currently received MD5 value sent by the second terminal.

Step 207, the server sends the preview information to the receiver.

The server transmits the determined preview information to the second terminal of the user B.

And step 208, the sender sends the file to the receiver in real time.

And the first terminal of the user A instantly transmits the PDF file to the second terminal of the user B through the QQ.

Step 209, the receiving party receives the preview information of the file, receives a file receiving instruction input by the user according to the preview information, and receives the file sent by the sending party in real time according to the file receiving instruction.

The second terminal of the user B receives the preview information of the PDF file from the server, and the user B considers that the file is the content required by the user B according to the content in the preview information (such as the content in table 1), and needs to view the full-text content of the thesis, and the second terminal of the user B receives the file instantly through the QQ.

It should be noted that step 208 may be performed after step 204, and the specific timing is not limited.

Optionally, the receiving party receives preview information of the file, receives a file rejection instruction input by the user according to the preview information, and receives the file sent by the sending party in real time according to the file rejection instruction.

The second terminal of user B receives the preview information of the PDF file from the server, and user B considers that the file is not the content required by user B according to the content in the preview information (see table 1), and the second terminal of user B may refuse to receive the file.

In the embodiment of the invention, in a scene that a sending party sends a file to a receiving party in an instant mode through a social application (such as QQ), the sending party analyzes the file to be transmitted to obtain the basic information and the preview information of the file to be transmitted, and the sending party sends the preview information to the server, so that the file analysis pressure of the server is greatly reduced. Then, the basic information is transmitted to the receiving side. The receiving party can acquire the preview information of the file from the server through the characteristic value of the file in the basic information, so that a user can determine whether the file needs to be received in real time according to the content of the preview information, and if the user determines that the file needs to be received, the receiving party receives a file receiving instruction input by the user and receives the file in real time according to the file receiving instruction. In the embodiment of the invention, the service for providing the preview information can be applied to an application scene of instant transmission through social application (for example, QQ), so that the situation that the service for providing the preview information in the process of transmitting the file can only be applied to non-instant transmission in the traditional method is changed, and the applicability is enhanced.

It should be noted that, in the above embodiment, an application scenario of instant messaging of a social application (e.g., QQ) is taken as an example for description. Referring to fig. 4, the present invention further provides another embodiment of a method for processing a file to be transferred, which is applied to a scenario of a non-instant file to be transferred.

Steps 401 to 403 are the same as steps 201 to 203, and are not described herein.

Step 404, the server stores the preview information.

Optionally, when the time for storing the preview information by the server is longer than a preset value, the server may clear the preview information. For example, if the time length for storing the preview information is longer than 60 days, the server clears the preview information, so as to save the storage resources of the server.

Steps 405 to 408 are the same as steps 204 and 207 in the embodiment corresponding to fig. 2, and are not repeated here.

Step 409, the sender sends the file to the server.

Step 410, the server caches the file.

Optionally, the server may clear the file. For example, if the size of the file is larger than the preset value, the time limit for the server to store the file is one month, and the server clears the file after one month, so as to save the storage resource of the server.

Step 411, the receiving party receives the preview information from the server, receives a file downloading instruction input by the user according to the preview information, and obtains the file from the server according to the file downloading instruction. The embodiment of the invention can be applied to the application scene of non-instant transmission. A brief description of the application scenario for non-instant delivery follows.

For example, user a wants to send the introduction of vacation mountain to user B, and sends the introduction to user B through non-real-time transmission such as QQ mailbox. Then, the first terminal of the user a parses the picture file through the QQ mailbox to obtain the basic information and the preview information of the file, where the preview information of the file is thumbnails of multiple pictures in the introduction material.

The first terminal of the user A sends the preview information to the server.

And the first terminal of the user A sends the transmission request of the picture file and the basic information of the picture file to the server through the QQ mailbox, and then the server sends the transmission request of the picture file and the basic information to the second terminal of the user B.

When the user B opens the QQ mailbox, the new mail is found, the QQ mailbox of the second terminal receives the basic information according to the transmission request, and the second terminal displays the basic information of the file to the user through an application interface of the QQ mailbox, so that the user B can see the file type, the file size and the like of the file. User B wishes to see a preview of the introductory material.

The second terminal of user B sends the MD5 value for the file to the server. The server receives the MD5 value of the PDF file sent by the second terminal of the user B, and at the moment, the server determines the preview information (thumbnail) of the picture file matched with the MD5 value according to the currently received MD5 value sent by the second terminal, and sends the preview information (thumbnail) to the second terminal of the user B.

The sender can send the introduction material of the picture file to the server. The server caches the file. And the second terminal of the user B receives the preview information from the server, the user B is interested in the vacation mountain after seeing the thumbnail of the file in the QQ mailbox interface and hopefully can see the full-text content of the file, then the second terminal receives a file downloading instruction input by the user B, and the file is obtained from the server according to the file downloading instruction.

The embodiment of the invention can be applied to the application scene of the instant transmission file and the application scene of the non-instant transmission file, and has wide application range. Meanwhile, the file to be transmitted is analyzed by the sender, so that the analysis pressure of the service is greatly reduced.

Referring to fig. 5, another embodiment of a file transfer processing method according to the present invention includes:

step 501, a sender determines a file to be transmitted.

This step should be understood with reference to step 201 in the embodiment corresponding to fig. 2, which is not described herein again.

Step 502, the sender judges whether the basic information of the file exists. If the basic information of the file exists, executing step 503, and if the basic information of the file does not exist, executing step 505;

the first terminal of the user a determines whether there is the basic information of the file. For example, (1) the basic information of the file may be that transmitted by the third terminal of the user C to the first terminal. (2) The first terminal has parsed the file once, and the first terminal has cached the basic information of the file, and in the two cases, the first terminal of the user a has the basic information of the file.

For example, in the first case, the first terminal of user a receives the compressed packet file sent by the third terminal of user C, so when the first terminal of user a is again used as the sender, the first terminal of user a forwards the received compressed packet file to the second terminal of user B, and the first terminal of user a has the basic information of the compressed file.

Step 503, judging whether the server stores preview information of the file according to the characteristic value of the file in the basic information; if the server does not have the preview information of the file, execute step 504; if the server stores the preview information of the file, step 507 is executed.

For example, the first terminal of the user a determines whether the server has the preview information of the compressed package file by the MD5 value in the basic information of the compressed package file. The specific method can be as follows: the first terminal of user a transmits the MD5 value to the server so that the server matches the preview information matching the MD5 value based on the MD5 value, feeds the preview information back to the first terminal if the server determines that there is preview information matching the MD5 value, and feeds a response to the first terminal if the server determines that there is no preview information matching the MD5 value, the response indicating that there is no preview information matching the MD5 value in the server.

Step 504, if the server does not have the preview information, the sender analyzes the preview information of the file according to the file type in the basic information.

The specific method for analyzing the preview information of the file according to the file type of the file may be:

firstly, determining the display type of the preview information corresponding to the file type according to the file type of the file.

For example: (1) and if the file type of the file is the document file, determining that the display type of the preview information corresponding to the document file is the text abstract. (2) And if the file type is a multimedia file, determining the display type of the preview information corresponding to the multimedia file as a thumbnail. The multimedia files comprise audio files, picture files and video files. (3) And if the file type of the file is the compressed package file, determining that the display type of the preview information corresponding to the multimedia is a file directory.

And then, analyzing the file according to the format of the display type to generate preview information of the file.

(1) And analyzing the file according to the format of the text abstract to generate text abstract information before the Nth page of the file, wherein N is a positive integer. (2) And analyzing the multimedia file according to the format of the thumbnail to generate the thumbnail information of the file. (3) And analyzing the compressed package file according to the format of the file directory to generate directory information of the file.

In the embodiment of the present invention, the file to be sent may be described by taking a compressed package file as an example, and then the preview information of the compressed package file is directory information of the compressed package file.

The sample of the preview information in the embodiment of the present invention can be understood by combining with step 202 in the embodiment corresponding to fig. 2, which is not described herein again.

It should be noted that after step 504, step 506 is performed directly.

Optionally, in step 505, if there is no basic information of the file, the sender parses the file to obtain the basic information and the preview information of the file.

Step 506, the sender sends the preview information to the server.

And step 507, the sender sends the transmission request of the file and the basic information of the file to the receiver, so that the receiver acquires the preview information of the file from the server according to the characteristic value in the basic information.

For example, a first terminal of a user a sends a transmission request and basic information of a compressed package file to a server, the server forwards the transmission request and the basic information of the compressed package file to a second terminal of a user B, then, the second terminal may send an MD5 value in the basic information to the server, after receiving the MD5 value, the server determines preview information with a matched MD5 value, and then, the server feeds the preview information back to the second terminal of the user B.

In the embodiment of the invention, before a sender analyzes a file to be transmitted, whether basic information exists can be judged firstly, if the basic information exists, whether preview information is stored in a server can be judged continuously through the characteristic value in the basic information, if the server has the preview information, the sender does not need to analyze the preview information of the file to be transmitted, the characteristic value in the basic information can be reused as an index, the preview information of the file does not need to be analyzed every time, and the analysis pressure of the sender is reduced.

It should be noted that the embodiment of the present invention may be applied to an application scenario of instant messaging, and may also be applied to an application scenario of non-instant messaging, for example, after step 507, the sender may send a file to the receiver in real time through a social application. Alternatively, the sender may send the file to the server, and the receiver may obtain the file from the server.

As described above, a method for processing file transmission is described, and an embodiment of the present invention further provides a terminal, please refer to a schematic structural diagram of the terminal 600 shown in fig. 6, where the terminal includes:

a determining module 610, configured to determine a file to be transmitted;

the parsing module 620 is configured to parse the file determined by the determining module 610 to obtain basic information and preview information of the file, where the basic information includes a feature value of the file;

a sending module 630, configured to send, to the server, preview information of the file analyzed by the analysis module 620;

the sending module 630 is further configured to send a transmission request of the file and basic information of the file to the receiving party, where the transmission request of the file is used to instruct the receiving party to receive the basic information, so that the receiving party obtains the preview information from the server through the feature value.
