Step 304, server judges user B terminal according to the application information of the user B of preservation terminal Whether file that user A share can be handled, if can be so that otherwise execution step 306 performs step 308.Step 306, the file shared is transmitted to user B terminal, handled by user B terminal when the terminal for judging user B can handle the file shared by server.

Step 308, when server judges that user B terminal can not handle the file shared, the form that can be handled the document analysis shared for user B terminal by server, such as text and/or picture etc., the part or all of composition information for the file shared can also be recorded.

Step 310, the content of the forms such as server is parsed text, picture and part or all of composition information, which are integrated, saves as webpage format.Certainly, server can also be converted to the form for sharing file other multiple formats, such as the general form of terminal when the file to sharing is handled（Such as text or picture）Or be the manageable file format of specified application in user B terminal, it is possible to by the terminal of the direct file transfer of these forms to user B.Illustrated herein by taking webpage format as an example.

Step 312, server transmits the address of the webpage of above-mentioned preservation to user B terminal, and user B realizes acquisition and further processing to corresponding contents by accessing the web page address.In addition, user B can select also to preserve original file download of sharing into its terminal.

Fig. 4 shows the module map of cloud server according to an embodiment of the invention.

As shown in figure 4, cloud server 400 according to an embodiment of the invention, including：

File storage module 402, there is provided share file to document processing module 406 for the file of sharing shared for storing user A to need to user B, it is ensured that acquisitions of the user B to file.

End message memory module 404, mounted application information in terminal for storing user B, title, version and/or the release of such as application program, authority etc., the application information is provided to document processing module 406, so that document processing module 406 judge that what whether user B terminal can handle user A shares file.

Document processing module 406, for according to file storage module 402 and the incoming data of end message memory module 404, judging that what whether user B terminal can handle user A shares file；Its file format for supporting to open is saved in such as application program " Go Book ", end message memory module 404（The forms such as such as txt, log, ebf）, it is assumed that user A Study document is pdf, if being judged as handling, and returns to analytic parameter to parsing module 408, if can handle, this is shared into file and transmitted to user B terminal.

Parsing module 408, for deciding whether resolution file content according to the incoming analytic parameter of document processing module 406, and shares the type after document analysis；If necessary to parse, then file content is parsed, and file content is arranged, by being converted to the file format that user B terminal can be supported, the form that such as " Go Book " can be supported, or the form that other applications can be supported, so that the file after by the way that form is changed is transmitted to user B terminal, the file after directly being changed to the form is handled.

Specifically, such as the content obtained to sharing document analysis can be saved as webpage by parsing module 408（Discarded for the part that can not be parsed）, so as to by the way that the address of the webpage is transmitted to user B terminal, can directly browse the script user A content for sharing file, and perform further processing operation.

Fig. 5 A to Fig. 5 D show the terminal interface schematic diagram for performing sharing files according to an embodiment of the invention.As shown in Figure 5A, user sees the file 502 that contact person " Zhang San " shares in terminal 500, if user needs to check the file 502 shared, can be clicked on by touch screen（In the present embodiment so that touch screen is clicked on as an example, naturally it is also possible to performed on the screen interface of terminal 500 default operating gesture, in pressing terminal 500 physics specified by The modes such as key are chosen to the file shared）The file 502 shared, then whether server end can handle the file 502 shared to terminal 500 and judge, if it is determined that terminal 500 can handle the file 502 shared, then terminal 500 directly downloads the file 502 shared, and is handled；If it is determined that terminal 500 can not handle the file 502 shared, then the form for the file 502 shared is changed, general file format can be converted to, such as text, picture format can also be converted to the file format that specified application can be handled in terminal 500.

The application information of the terminal that is stored with server 500, whether server can handle the file 502 shared to terminal 500 accordingly judges.Storage application information in the server can server periodically asked for terminal 500, can also be server when detecting the presence of the file shared to terminal 500, asked in real time to terminal 500, can also by terminal 500 by the application program update situation real-time synchronization of itself into server.

In Fig. 5 A, user " Zhang San " is sometime recommending the file 502 shared to the user of terminal 500, then the file 502 shared is uploaded and stored to server（Such as now shared using " Sina weibo ", then the server is " Sina weibo " corresponding server）In.Terminal 500 may be instantly available prompting, it is also possible to be pointed out over time, become, but as long as the file 502 shared is stored in server, terminal 500 can be obtained to it at any time.

Therefore, the scene shown in Fig. 5 A is non real-time data sharing；And the application is actually used in real-time data sharing, specifically as shown in Figure 5 B.

Such as active user（The user of terminal 500）Immediate communication tool is used with user " Zhang San "（Such as QQ, wechat, Fetion, Michat）Interact.The file 502 that user " Zhang San " can carry out active user in data sharing, such as Fig. 5 B to share is " social psychology .pdf'.User " Zhang San " can send in the window chatted with active user in real time needs the data shared, such as the file 502 shared, then server will be kept in the file 502 that this is shared, and enter row format conversion to it if necessary.

Server can immediately be judged after the data 502 shared are received（Judge that can terminal 500 be directly handled it）With form conversion；Server can also immediately be judged after the data 502 shared are received, and receive destination object（Such as terminal 500) download request when, then enter in real time row format conversion；Server can also receive destination object（Such as terminal 500) download request when, then in real time carry out judge and form conversion.

Meanwhile, shown when on the screen interface of terminal 500 corresponding to other users（Such as " Zhang San "）Sharing data content when, such as show that " during social psychology .pd, terminal 500 can download corresponding file data from the request of trend server in Fig. 5 A and Fig. 5 B；Or, terminal 500 Fig. 5 A with show that " social psychology pdf' are only the mark of data 502 that corresponds to and share; when user operates to the mark, such as click on the mark, and the ability of terminal 500 is to server transmission download request in Fig. 5 B.

Server enters after row format conversion for the data 502 shared, and obtained file format has a variety of situations, two kinds of embodiments therein introduced below：

Embodiment one

Server can be converted to the form for the file 502 shared general format, i.e., all terminals are uniquely able to the form opened, then terminal 500 can necessarily be handled.Specifically, general format can be for text, picture, webpage etc., can one kind optionally therein, it would however also be possible to employ the combination of multiple format.

By taking webpage as an example.Server can parse the contents such as text, the picture in the file 502 shared, will be above-mentioned Content integration simultaneously saves as webpage format, then web page address is transmitted to terminal 500, the web page address that user receives according to terminal 500, open and the file after format transformation is handled, as shown in Fig. 5 C, shown on the interface of terminal 500 for the web page contents 504 after parsing.

Simultaneously, server can also be recorded to the composition information of the contents such as text, the picture in the file 502 shared, and when generating web page contents 504, typesetting is carried out according to the composition information, so that active user can obtain the files after transform being consistent with the content for the file 502 shared as much as possible.

In addition, although the application can provide the file after form conversion for active user, but user still can select the original that download is changed without form（The file 502 shared).Specifically, such as user, can be by clicking on the cue button 506 shown in Fig. 5 C, so that by the file 502 shared (not shown in figure in processing procedure）Download and preserve into terminal 500.

Embodiment two

Application information of the server in terminal 500, the file type that specified application can be handled is converted to by the file 502 shared.As shown in Figure 5 D, such as when being provided with the application program " Word " for handling word document in terminal 500, then server can be converted to the form for the file 502 shared application program " Word " manageable form, such as suffix is the file of " .doc ".In Fig. 5 D, what is shown on the interface of terminal 500 is the word document content 508 after form conversion.

As shown in Fig. 5 E, server is judging that terminal 500 can not handle the file 502 shared (not shown in figure）When, prompting menu 510 can also be ejected on the interface of terminal 500 to prompt the user whether to download related application program, after user downloads and installs corresponding application program, when the terminal 500 is received again by the file of same type, the file of the type is directly handled by mounted application program, without being changed, the time of user's pending file conversion is saved.Certainly, the prompting menu 510 it is not necessary to, corresponding application program directly can be pushed to terminal 500 by server, and be installed automatically by terminal 500.

Technical scheme is described in detail above in association with accompanying drawing, it is contemplated that in the prior art, user is when seeing the file shared, it is impossible to judge whether terminal can be handled the file shared.And by, it is necessary to continue to download corresponding application program or form to file is changed, numerous Suo operation has had a strong impact on the experience of user when can not be handled after file download.Therefore, the present invention proposes a kind of new sharing files scheme, the data such as the file shared can be entered with row format conversion so that the recipient of file, also can be by checking that the file after conversion learns the content shared in file when non-installation process shares the application program of file.

The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for those skilled in the art, the present invention there can be various modifications and variations.Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection.
