Already existing document is also possible to user and passes through the document for oneself writing preservation.Document includes but is not limited to: work log,
Corporate mail, the soft text of push, product demand, bid for a project etc. need team at same time, different location cooperation simultaneously
The document of reason.Simultaneously as using distributed server, it can be 2 people, 3 people to ten thousand people in the number of the client 101
More than, it can receive the document of transmission.Other clients 101 can be sent documents in several ways, for example are passed through
Document is sent directly to client 101, the cloud address chain sending and receiving of document and document can also be sent to client 101.
Cooperation permission is arranged when sending the document by step S102, and different associations can be arranged according to different requirements,
Make permission.For example, Joint Designing activity scheme in team, it is necessary to following permission be arranged: the document established is sent to
Other teamworkers, it is the permission for possessing editor's document that teamworker, which opens document, can immediately engage in and write document.For example, document
Founder need to write privacy log, then need by the cooperation priority assignation of document be only founder oneself read, editor,
Other people do not have permission viewing.For another example, completed rules and regulations are sent to common employee and known by the founder of document, institute
The document write, other people do not have permission to modify, can only read；Need be arranged be suitable for completed it is not necessary to modify text
Shelves, are sent to the cooperation permission of the situation for the spectators that other need to read.Above-mentioned permission can carry out permission switching, switching
Mode includes but is not limited to issue cooperation request to switch permission if document creator is agreed to.
Step S103 synchronizes cooperation in the client 101 according to the cooperation permission, is based in client 101
The cooperation permission of step S102 setting, carries out corresponding synchronous collaboration.Specifically, client 101 receives sender's transmission
Document analyzes the cooperation permission of setting, and cooperation permission is carried out execution cooperation on the client 101, executes the interior of cooperation
Holding includes reading, modifying, annotate etc., and the execution cooperation after Document Creator, will execute reading, the text of document in client 101
Shelves modification, document annotation operation.As preferred in the present embodiment, voice and video can be carried out in client 101
It imports, such as by the APP real-time recording on mobile phone terminal it is achieved that can also be real-time by the application in computer end
Recording is realized.
The content synchronization of cooperation described in step S104 is saved to cloud, same by carrying out the content of the cooperation beyond the clouds
Step, can be realized the synchronization to the content of cooperation.Described synchronize refers to that document automatically saves beyond the clouds immediately, without protecting manually
It deposits, also avoids power-off etc. and cause the loss of file content, and eliminate and carry out the staged files using the equipment copied files such as USB flash disk
Work.Further, in the present embodiment, by synchronizing cooperation in the client according to the cooperation permission, and will
The content synchronization of the cooperation is saved to cloud, be can be realized the more equipment strange lands of more people while being cooperated beyond the clouds, to solve
Mail confirms file, wastes time the problems such as each synchronous documents repeatedly, improves the efficiency of cooperation.In the present embodiment,
The server-side in cloud can be single server-side mode, be also possible to Distributed Services end mode.It is deployed with multiple down beyond the clouds

Referring to FIG. 2, being in Fig. 1 with the timing diagram of buyun collaboration method.
Including following several interactive objects:
Customer end A, Cloud Server, customer end B, client N,
In the customer end A, it will be sent to Cloud Server after document setup cooperation permission, the customer end A is as this article
The generation end of shelves or source file provider.After the Cloud Server receives document, the transmission document that band is had permission is extremely
Customer end B, after the customer end B receives, according to cooperation permission setting, modify, annotate to the document, commenting on or
Storage.In the customer end B, collaborative content is synchronized, is saved to cloud.Further, it in client N, continues to
To the document for being provided with cooperation permission, and synchronizes and cooperate with other client's degrees.
Referring to FIG. 3, being a kind of cooperation permission mode implementation process schematic diagram in Fig. 1.
In the present embodiment, cooperation permission is that private cloud stores permission, is comprised the following steps that
The document setup is editable and is sent to client 302 by step S301；As the teamworker of client 302
Opening document is the permission for possessing editor's document, can immediately engage in and write document,
Step S302 is edited and is annotated to the document content in the client 302, and by the content of edit and/
Or annotation is synchronous beyond the clouds；As preferred in the present embodiment, the document for participating in writing will in the client 302 and
By the document setup be editable promoter client on synchronously shown.At this point, cloud synchronizing speed is almost
Meanwhile and can store each word or picture that user edits immediately, by ICP/IP protocol, carry out between client
Data exchange.
For step S303 in annotation content, document content is editable state, and the document format is web document.It is described
The output format of document includes but is not limited to: the electronic document of ePub format, the electronic document of PDF format, the electronics of TXT format
Document.Step S304 is in content of edit, using based on data structure DIFF technology, the modification of real time contrast's document content.It is real
When comparison document content modification refer to, for example, the initial position of document includes: the overall offset word of starting content in a document
Number；The end position of document includes: to terminate the overall offset number of words of content in a document.As preferred in the present embodiment, reality
When comparison document content the mode of modification include:
1) original document is transferred to browsing terminal by file transfer protocol to carry out after sharing, carries out rights document
Initialization；Initialization operation is included in and opens document, saves document.In order to guarantee the original state and operation of each browsing terminal
The state consistency of terminal, it is necessary first to carry out a complete original document initially by net distribution to each browsing terminal
Change, using the content of the initialization document as the basic point updated.Initialization operation further includes saving document content, mainly with two
Document content is saved in memory file or is cached by the format of system.
2) change of document content is waited；
Edit operation of the user to document is waited, doing edit operation to shared document content includes: to increase text, deletion
Text, modification format, insert pictures, figure and sound.Need to trigger preservation operation when the modification of document reaches a certain amount grade,
And in a binary format by modified document storing into a new memory file.
3) document after change and the content before change are subjected to comparison in difference；
Document content seen in documents editing may be Chinese character, character, it is also possible to the various performance shapes such as picture
Formula splits the document content before change and the document content after change, and can then proceed in specified keyword will be interior
Deposit that file declustering is blocking, record each blocks of files size, initial position in a document and end position, then to each
A blocks of files carries out comparison in difference, to obtain the content of document variation.
It is a kind of general computerized algorithm as preferred in the present embodiment, described DIFF technology, what neat book used
DIFF technology is based on disclosed algorithm, but has innovation in use.In general, DIFF algorithm can compare two sections of different texts
Between difference, generate PATCH, such as the comparison of AC and ABC in, according to DIFF algorithm can obtain in AC be inserted into letter b then
Equal to ABC.In the comparison of text, DIFF algorithm has directly been used in the present embodiment, but in paragraph, picture, format (ratio
Such as hyperlink, overstriking) modification in terms of, common DIFF algorithm is helpless, as preferred in the present embodiment, using data
Format DIFF technology, for the data format of the common stores such as JSON (JAVA SCRIPT OBJECTNOTATION), using this
Application program based on DIFF algorithm development in embodiment can perception data structure change, such as insert pictures in the line
Or the font of extended formatting, it just can be carried out synchronization in other clients.
Step S305 is recorded and is synchronized to document by carrying out two-way communication between WebSocket agreement and server 301
The modification of content；The server 301 is local or cloud；The WebSocket agreement used in the present embodiment is to be based on
The new agreement of one kind of HTML5 is locally taken to realize browser and server full-duplex communication (full-duplex) with this
Business device or the server in cloud can actively transfer data to client.
Specifically, communication protocol uses the WebSocket of standard, and internal frame data are JSON format.Citing, with
The data format issued when changing for text down:
[" EDIT ", " s2ft36 ", [+23,12@@of [0,1, "@@- 23,8 nframe%E6%95%B0%E6%
8D%AE%E4%B8%BA n+JSON n "]], [], []].
The modification of document content described in step S306 is encoded based on Unicode, the Unicode (Unicode, Unicode,
Single code) it is an industrywide standard, including character set, encoding scheme etc. in computer science.
Fig. 4 is another cooperation permission mode implementation process schematic diagram in Fig. 1.
Another kind cooperation permission mode are as follows: client only reads permission,
Step S401 is arranged after the document structure tree in addition to document collaboration person, and other clients 302 are without the power of amendment
Limit, this setting is unrelated with the format of document, related to permission, holds power and is limited to only read, then only document collaboration person can be to document
It is operated, the number of document collaboration person can be according to circumstances added.Or without teamworker's permission, only document structure tree person can
To read and be synchronized to cloud.
For step S402 by adjusting permission, the cooperation permission is that client only reads permission, after the document structure tree,
If client is teamworker's permission, there is document modification authority；If client is not teamworker and document structure tree person, in client
, without modification authority, there is reading permission at end to document to document；Above-mentioned client includes that multiple, described teamworker's numbers can be with
It is 0, one can be included at least as preferred in the present embodiment, above-mentioned teamworker.
For example, the founder of document needs to write privacy log, then need the cooperation priority assignation of document to be only to create
The person of building oneself reads, edits, other people do not have permission viewing.
Referring to FIG. 5, being another cooperation permission mode implementation process schematic diagram in Fig. 1.
Another kind cooperation permission mode can be with are as follows: and cooperation permission is that barrage comments on permission,
Step S501 uses WebSocket technical communication, using the comment of newest publication as barrage form；The newest hair
The comment of cloth, sequentially in time or the prompt of setting is identified and is grabbed.Those skilled in the art can be illustrated,
The barrage form can be carried out shielding based on " keyword " or be shown according to " time point ".Execute WebSocket technical communication
The web browser of operation includes: Chrome, Firefox, Internet Explorer, Opera, Safari.
Step S502 is added on the transparent view by the additional layer transparent view on the view layer of the document
Carry the content of barrage；
The document setup is directly to comment on permission by step S503；Directly comment permission refers to not by loading barrage,
But by direct written form as comment.If client 301 is WEB terminal and needs to load video, net is generated in WEB terminal
Page floating layer generates at least one webpage floating layer by default script, using at least one webpage floating layer as being used to show barrage
The window of data passes through webpage floating layer, the broadcasting frame number of foundation broadcasting video in the predetermined position of the display area of video elementary
Information and/or play time information accordingly show barrage data.
Step S504 applies for editor's document permission in the client 302, after one side of generation of the document agrees to,
The client is edited.Need to first determine whether the client 302 has cooperation permission, to document carry out editor or
Annotation, if client 302 needs to make requests to one side of generation of document, when the life of document without editing or annotating permission
After Cheng Yifang agrees to, 302 side of client can be marked or annotate to document.If client 302 has had editor
Or modification authority is directly operated then woth no need to make requests to one side of generation of document.
Referring to FIG. 6, being the signal of the more equipment real-time synchronization cloud collaboration methods of more people in one embodiment of the present invention
Figure.
The content of step S601 synchronous collaboration includes: synchronous picture and text, simultaneous voice, synchronization video, synchronous annotation, synchronizes
Pass, those skilled in the art can be illustrated, and the synchronous picture and text include but is not limited to: bmp, jpg, tiff, gif, pcx, tga,
Exif, fpx, svg, psd, cdr, pcd, dxf, ufo, eps, ai, raw etc..The simultaneous voice includes but is not limited to: synchronous hair
Recording, music and the voice sent.The synchronization video includes but is not limited to: AVI, ASF, WMV, 3GP.The synchronous annotation packet
It includes but is not limited to, the author of time synchronization, position synchronization and annotation is synchronous.The synchronized upload includes but is not limited to: text
Word, picture, sound and video.
Whether step S602 has network insertion, and the method for judging whether there is network insertion is to be in the desktop computer of WEB terminal
No to be attached by ICP/IP protocol and internet, whether the mobile phone at wechat end passes through GPRS general packet radio service skill
Art or other network insertions.It is synchronized to cloud after accessing network, is saved if not accessing network to local.
Referring to FIG. 7, being the specific embodiment schematic diagram that the document is sent to an at least client in Fig. 1.
The method that the document is sent to an at least client by step S701 are as follows:
Or step S702 is executed by access wechat end, obtain or send document；Chat or group chat at wechat end
Interface acquires document or sends document to other side, changes editor and completes to forward other people cooperation mode, Duo Rentong again
When Yun Xiezuo, improve efficiency；
Or execute after step S703 replicates the chained address of the document and be sent to client, client passes through the chain
It is grounded location and opens document；It is sent to client behind chained address by replicating the document, client is grounded by the chain
Document is opened in location, changes single single device mode of operation, and response saves energy consumption, and All Files will all save beyond the clouds,
Mobile phone, computer, ipad are edited simultaneously, without waiting for update and synchronization time.By way of directly transmitting link, by will be literary
Shelves are sent to client, change the mode of operation that editor saves manually, store immediately, improve document security.
Or execute step S704 and pass through the document structure tree uniquely corresponding two dimensional code, client passes through scanning described two
Document is opened after dimension code；For example user opens mobile phone and applies " sweep and sweep ", scans the two dimensional code of sharing, i.e., openable document.It is logical
Document is sent to client by the mode for crossing two-dimensional code scanning, is changed the mode of operation that editor saves manually, is stored immediately,
Improve document security.
It is above-mentioned specifically, chained address in step S705 is cloud chained address or local links address.
It is the cross-platform cooperation schematic diagram in one embodiment of the invention as shown in Figure 8.
In the present embodiment, the client 804 includes: WEB terminal 801, application program end 802, wechat end 803, described
Client 804 includes wechat end 803 in intelligent mobile terminal, WEB terminal 801 or application program end 802, desktop computer and pen
Remember and is locked after the WEB terminal 801 on this computer, the content synchronization of the cooperation are saved to cloud in client.
It is the more equipment real-time synchronization cloud cooperative system structural schematic diagrams of more people in one embodiment of the invention as shown in Figure 9.
In the present embodiment, the more equipment real-time synchronization cloud cooperative system structures of more people include:
Document creation module 901, the document creation module are sent at least one visitor to generate document, and by the document
Family end；As preferred in the present embodiment, the document format of generation includes but is not limited to word, TXT, PDF etc..By the text
The method that shelves are sent to an at least client includes but is not limited to be sent to client behind the chained address for replicating the document,
Client opens document by the chained address；I.e. by way of sharing link, document is shared, client passes through
The chained address is opened, document can be opened and sees the content of document.In the present embodiment, it will be sent to behind chained address
Client is actually: realizing a Web site.Technical solution is available there are many Web site is usual, most common to have
Tetra- kinds of technical solutions of ASP, ASP.NET, PHP, JSP.Under ASP, ASP.NET, PHP, JSP environment, HTML code is mainly responsible for
The Show Styles of description information, and program code is then used to processing business logic (such as inquiry database etc.).ASP,
ASP.NET, PHP, JSP is provided mixes certain program code in HTML code, when user browses webpage by browser,
Web server can call corresponding apps server to execute program code therein, ultimately produce the html of a standard
File sends back to the browser of client.Further, when chained address be static page, then pass through web browsing in client
Device requests static page, and the static page is then searched on Web server, asks finally, Web server sends static page request to
Browser is asked to be shown.
Further, when chained address be dynamic page, then client by Web browser request, then Web service
Device searches the page and passes it to apps server, and the apps server searches the finger in the dynamic page
It enables and is formed and complete page (apps server therein reads the code in dynamic page, and explains and execute these codes, then
Code is deleted from page.Resulting result will be one static html pages), the Web server is sent to page is completed
Browser is requested, the page of completion is passed back to Web server by apps server.
Further, when chained address be data base querying request, then can be located at by apps server use
The document resources of server end are communicated using apps server and by database device as medium.
For example the dynamic web page for passing through asp is exactly to access database by a component ado of Microsoft's offer.It is built in driver
After vertical communication, database will be executed and inquire and create a record set.Record set is one or more tables from database
The data subset of middle extraction.Record set will return to apps server, and data will be applied onto dynamic page.
Or uniquely corresponding two dimensional code, client are literary by opening after scanning the two dimensional code by the document structure tree
Shelves；Client carries out the sharing of document by scanning " two dimensional code ".Or by access wechat end, document is obtained or sent, is passed through
The communication protocol at wechat end can directly show document, for example document owner arrives " friend by sharing document
Circle " may be implemented that the user of other clients is allowed to carry out further operating to document.The chained address is cloud chained address
Or local links address.
Authority module 902, the authority module is to the setting cooperation permission when sending the document；It is described by the text
Shelves are set as editable and are sent to client；The document content is edited and annotated in the client, and by institute
It states content of edit and/or annotation is synchronous beyond the clouds；In content of edit, using based on data structure DIFF technology, real time contrast
The modification of document content；The modification of the document content is encoded based on Unicode；By WebSocket agreement and server it
Between carry out two-way communication, record and synchronize the modification to document content；The server is local or cloud.Further,
The permission that cooperates is that private cloud stores permission, by the way that permission is arranged, carries out the cooperation between the teamworker of identity restriction；If not weighing
The new user of limit needs that cooperation is added, then needs to obtain the authorization of document creator；Before authorization goes through, user can be
Line waits, once other side's approval movement is completed, document will refresh automatically and enter edit page.Further, cooperate permission
Permission is only read for client, after the document structure tree, is arranged in addition to document collaboration person, other clients are without the power of amendment
Limit；By adjusting permission, first teamworker, second teamworker, third teamworker ... and the N+1 reader are carried out
Form, N are natural number.Further, cooperation permission is that barrage comments on permission, is that barrage comments on permission by the document setup,
Using WebSocket technical communication, using the comment of newest publication as barrage form, by the view layer of the document
Additional layer transparent view loads the content of barrage on the transparent view；Or by the document setup be directly comment
Permission edits document permission in the client application, after one side of generation of the document agrees to, carries out in the client
Editor.
Synchronization module 903, the synchronization module is to synchronize cooperation in the client according to the cooperation permission.
On the synchronization module 903, during carrying out line by WebSocket agreement, issued by the browser of client
The request of WebSocket line, then background server, which issues, responds, i.e., " shakes hands " (handshaking).
Client 905, the client is to receive generation document and carry out synchronous collaboration；Due to the synchronous collaboration
