It should be noted that browser in the embodiment of the present invention can be mobile terminal browser or non-moving End browser, the embodiment of the present invention is not specifically limited to it.Browser can be any type with html5 Webpage Application, the such as video player of webpage version or client edition, instant messaging application, browser application etc..The present invention is real Apply the browser in example and can have host process, the host process of browser can be used for processing the operation pages in browser for the user Upper performed operation and browser client carry out data interaction, process the various request of Client-initiated, process registration, readjustment Etc. event.The host process of browser can be also used for processing other events or request, no longer illustrates one by one herein.Browser Can also have the first application interface, this first application interface can be the application interface of browser host process, alternatively, first Application interface can be webworker, and wherein webworker connects for a kind of substandard application of browser host process of html5 Mouthful.Because browser host process is single thread execution, so it should avoid as early as possible in ui in browser page operating process Thread continually dom operation and complexity mathematical calculation, with reach avoid browser page interim card affect Consumer's Experience mesh 's.The embodiment of the present invention can be by the handling process of document transmission method and calculating process in the process of the first application interface Execution, so can mitigate the pressure of browser host process.Browser can also have the second application interface, and this second application connects Mouth can be the application interface that file is supported with streaming operation, and alternatively, the second application interface can be filereader, its In, filereader is a kind of substandard application interface that file is supported with streaming operation of html5.Using the second application interface Can realize the pretreatment operation to file, the size of such as calculation document, divide documents into multiple file fragmentations etc..Need Illustrate, the document transmission method of the embodiment of the present invention can using the host process in browser, the first application interface and Second application interface is realized to install the breakpoint transmission that plug-in unit can also realize file in a browser, and then can reduce clear Look at the setting of device, optimize the serviceability of browser.
Also, it should be noted the file destination in the embodiment of the present invention can be any type of file, such as text, Picture, audio frequency, video file etc., the embodiment of the present invention is not specifically limited to the type of file destination.The embodiment of the present invention Document transmission method can upload file destination in a browser, namely user can by browser by file destination transmit to Server, wherein, server could be for server browser being supported and safeguarding.Herein it should be noted that The document transmission method of the embodiment of the present invention can transmit file destination little for data volume to browser it is also possible to by data volume Big file destination transmits to server, and maximum can reach 8gb, even more greatly.
In the practical application scene to server transport file destination, user choose need transmission file destination it Afterwards, this file destination can be uploaded in the upload page of browser first, then the host process of browser can by with The data interaction of this upload page gets this file destination.Browser execution host process during, the first of host process Application interface can get this file destination from host process, and calls the second application interface of browser to draw file destination It is divided into multiple file fragmentations.Herein it should be noted that file destination is divided into multiple file fragmentations by the second application interface, its In each file fragmentation size can identical it is also possible to different.In the second application interface, file destination is divided into multiple literary compositions After part burst, the first application interface can calculate the cryptographic Hash of each file fragmentation in multiple file fragmentations respectively, above-mentioned Process is browser in the process to the pretreatment of file destination to before server transport file destination.Need explanation herein It is that, if the data volume of file destination is very big, browser single treatment will be very painstaking, now needs to divide file destination Become multiple file fragmentations, the division of file destination needs to rely on the second application interface filereader of browser, In filereader, file itself provides Fragmentation to realize file destination is cut, and filereader provides The api of readarraybuffer, can be in the form of being converted into buffer by the file fragmentation after cutting, in order to right with realization It carries out bit manipulation, and this is also the premise of the cryptographic Hash calculating each file fragmentation for browser by the first application interface.Also It should be noted that the computational methods of the cryptographic Hash of file fragmentation may be referred to the realization of md5, sha increased income, the present invention is implemented The computational methods that example is adopted to the cryptographic Hash of the first application interface calculation document burst are not specifically limited, herein no longer one by one Citing describes in detail.
Above-mentioned steps s202 to step s206 is one of cyclic process to server transport file destination for the browser, Namely above-mentioned steps s202 to step s206 be one of multiple file fragmentations from browser to server transport file destination The process of file fragmentation, is described in detail below above-mentioned steps s202 to step s206:
In the technical scheme that step s202 provides, browser, can be first to before server transport file fragmentation Send file transmission request to server, wherein, this document transmission request can serve to indicate that to server transport file destination. Herein it should be noted that browser pass through the first application interface and the second application interface the file destination getting is carried out pre- After process, each file fragmentation in multiple file fragmentations of file destination division and multiple file fragmentation can be obtained Cryptographic Hash, browser can carry in following information when sending file transmission request to server in file transmission request At least one of: the identification information of file destination, the size of file destination, the quantity of file fragmentation, the Kazakhstan of each file fragmentation Uncommon value, the information such as the size of each file fragmentation, label of each file fragmentation, can also carry it in file transmission request His information, no longer illustrates herein one by one.
In practical application scene, the first application interface that browser passes through host process please to server transmission file transmission Asking can be in the following ways: file transmission request can be xmlhttprequest, and the first application interface can be by calling Server pre-assigned http data transmission interface sends file transmission request to server.Herein it should be noted that clear Device of looking at can agree upon Data Transport Protocol and the response process for file transmission request in advance with server, works as browser After file transmission request is sent according to the Data Transport Protocol agreeing upon in advance to server by the first application interface, service Device can be carried out to this document transmission request according to the response policy decided through consultation in advance after being successfully received this document transmission request Response.
In the technical scheme that step s204 provides, server please in the file transmission receiving the first application interface transmission After asking, can immediately this document transmission request be responded, response process may include that and transmits request to this document first Parsed, therefrom got the identification information of file destination and the cryptographic Hash of each file fragmentation in file destination.Service Device can search whether the file having indicated by the identification information of file destination from locally stored, if finding such Whether file, then be transmitted through before this file destination is described on server, but be not aware that this file destination Upload complete.After server finds file destination in locally stored, server can continue to search for locally stored in The file fragmentation having existed and its corresponding cryptographic Hash, and will be locally stored in the transmission request of these cryptographic Hash and file in The cryptographic Hash of each file fragmentation of entrained file destination is compared, if the file fragmentation in server local storage Cryptographic Hash identical with the cryptographic Hash of certain file fragmentation in multiple file fragmentations of file destination, then explanation server in There is this document burst.Already present first file fragmentation collection in server be can determine that by above-mentioned response process server Close, wherein, the first file fragmentation set includes the file that in multiple file fragmentations of file destination, being serviced device has received and divides Piece.
Server is being responded to file transmission request to determine already present first file fragmentation collection in server After conjunction, can be sent to the first application interface of browser by pre-assigned http data transmission interface and confirm message, Wherein, this confirmation message can serve to indicate that already present first file fragmentation set in server.Server is to the first application Interface sends and confirms that message informs already present first file fragmentation set in the first application interface services device, is to notify the Next one application interface need not repeat to included file fragmentation in server transport the first file fragmentation set, but directly Connect the file fragmentation in addition to the first file fragmentation set in multiple file fragmentations of server transport file destination, to realize The breakpoint transmission of file, so can reduce and repeat to send the resource consumption caused by file fragmentation, reduce the process of browser Pressure.
Browser pass through first application interface the reception server send confirmation message after, can to received really Recognize message to be parsed, to determine already present first file fragmentation set in the server indicated by this confirmation message, enter And filter out the file fragmentation in addition to the first file fragmentation set from multiple file fragmentations of file destination, and these are civilian Part burst is transferred to server successively, and then realizes the breakpoint transmission of file destination.
In the technical scheme that step s206 provides, browser passes through the first application and receives confirmation message, and foundation should After confirming that message filtering goes out the file fragmentation in addition to the first file fragmentation set in multiple file fragmentations of file destination, clear Device of looking at can will remove the first file fragmentation set by the first application interface in multiple file fragmentations of the file destination filtering out Outside file fragmentation be transferred to server.Herein it should be noted that removing the first literary composition in multiple file fragmentations of file destination File fragmentation outside part burst set can be one or multiple, when removing in multiple file fragmentations of file destination When file fragmentation outside first file fragmentation set is one, browser can be by the first application interface directly by this residue File fragmentation be transferred to server, to complete the transmission of whole file destination；When removing in multiple file fragmentations of file destination When file fragmentation outside first file fragmentation set is multiple, browser can be by the first application interface from these remaining literary compositions Choose a file fragmentation to be transferred to server in part burst, and the alternative document in these remaining file fragmentations is divided Piece, then also need to transfer process shown in step s206 for repeated execution of steps s202, until these remaining file fragmentations are complete Portion is transferred to the transmission that server just can complete whole file destination.
As a kind of optional embodiment, step s206 browser will be removed in multiple file fragmentations by the first application interface File fragmentation outside first file fragmentation set is transferred to server and may include that
Step s2062, browser response confirmation message determines that the first file waiting to start to transmit in multiple file fragmentations divides Piece, wherein, the first file fragmentation is first file fragmentation or a random file fragmentation in the second file fragmentation set, the Two file fragmentation set include the file fragmentation in multiple file fragmentations in addition to the first file fragmentation set；
Step s2064, browser is started to server transport second literary composition from the first file fragmentation by the first application interface File fragmentation in part burst set.
In above-mentioned steps, it should be noted that browser receives server by the first application interface sending really After recognizing message, can respond thereto, with already present first file in the server according to indicated by this confirmation message The first file fragmentation waiting to start to be transferred to server is determined in burst set from multiple file fragmentations of file destination, herein It should be noted that " first " simply differentiation nominally herein, do not limit the order of file fragmentation.First file fragmentation Can be first file fragmentation in the second file fragmentation set or a random file fragmentation, wherein, the second file divides File fragmentation in addition to the first file fragmentation set in multiple file fragmentations that piece set includes in file destination.Need explanation , the second file fragmentation set can include one or more file fragmentation, and the first file fragmentation is the second file fragmentation One of in set, the file fragmentation in the second file fragmentation set can have sequencing it is also possible to not have successively Sequentially, when the file fragmentation in the second file fragmentation set has sequencing, the first file fragmentation can be that the second file divides In piece set first, to guarantee that server can receive file fragmentation according to the sequencing of file fragmentation, and then reaches Improve the accuracy of the file destination that server receives.When the file fragmentation in the second file fragmentation set does not have sequencing When, the first file fragmentation can be random one in the second file fragmentation set, and server can divide to the file receiving Piece is resequenced according to the identification information of file fragmentation to recover former file destination.Herein it should be noted that file divides The sequencing of piece can determine, wherein, the identification information of file fragmentation can be according to literary composition according to the identification information of file fragmentation The order of part burst label successively.
Also, it should be noted after the first file fragmentation is transferred to server by the first application interface by browser, Alternative document burst in second file fragmentation set is needed to repeat the step s202 extremely step in the embodiment of the present invention Rapid s206, namely the file fragmentation often sending in a second file fragmentation set is required for re-executing a present invention and implements Step s202 in example is to step s206.
In this embodiment, browser passes through according to received confirmation message from multiple file fragmentations of file destination The first file fragmentation is determined in the second file fragmentation set that file fragmentation in addition to the first file fragmentation set is constituted It is transferred to server, this first file fragmentation can be first or random in the second file fragmentation set, so may be used To avoid browser to repeat to transmit file fragmentation to server, and then can realize reducing the resource consumption of browser, optimize clear Look at device performance technique effect.
As a kind of optional embodiment, server is divided by the file that the first application interface transmits receiving browser After piece, the cryptographic Hash of the file fragmentation that server can be received using the calculating of the computational methods such as md5, sha, and will calculate To this document burst the transmission request of cryptographic Hash and received file in the cryptographic Hash of entrained this document burst enter Row compares, if both are identical, the file fragmentation that this document burst is file destination is described, then server will store this article Part burst and its corresponding cryptographic Hash, and this document burst is added to the first file fragmentation set；If both are different, say Bright this document burst is not the file fragmentation of file destination, and this document burst is likely to be illegal file, then server will be lost Abandon this document burst, and notify first application interface this document burst of browser to upload unsuccessfully, need again to upload this document Burst.
In this embodiment, server passes through to compare during the cryptographic Hash of file fragmentation receiving is asked with file transmission and is taken Whether the cryptographic Hash of the file fragmentation of band is identical, it is possible to achieve judge the received legitimacy of file fragmentation and safety, And then the accuracy of the file destination received by guarantee server.
As a kind of optional embodiment, step s202 browser is sent out to server by the first application interface of host process File transmission request is sent to may comprise steps of s2022 to step s2026:
Step s2022, browser calls the process of the first application interface, and entering to the first application interface by host process Journey transmits the first parameter, and wherein, the first parameter is used for pointing to file destination.
In the technical scheme that step s2022 provides, browser during execution host process, can call by host process The process of the first application interface, this invoked procedure between calling similar to function.Host process is calling the first application interface Can be used for pointing to the first parameter of file destination to the process transmission of the first application interface during process, so that the first application connects The process of mouth can be processed to file destination.
Step s2024, browser executes the process of the first application interface, at the file destination that the first parameter is pointed to Reason, obtains result, wherein, carries result in file transmission request.
In the technical scheme that step s2024 provides, browser redirects execution first application from the implementation procedure of host process The process of interface, to realize the file destination pointed by the first parameter is processed,
As a kind of optional embodiment, step s2024 browser executes the process of the first application interface, to the first parameter The file destination pointing to is processed, and obtains result and may include that
Step s20242, browser calls the process of the second application interface by the process of the first application interface, by target File is divided into multiple file fragmentations；
Step s20244, browser receives the many of the process return of the second application interface by the process of the first application interface Individual file fragmentation, and calculate the cryptographic Hash of each file fragmentation in multiple file fragmentations.
Herein it should be noted that the process to file destination can include but is not limited to: obtain the mark of file destination Knowledge information, obtain the data volume size of file destination, file destination is divided into multiple file fragmentations, divides for each file fragmentation Join identification information and calculate cryptographic Hash of each file fragmentation etc..Also, it should be noted file destination division need according to Second application interface filereader of bad browser, in filereader, file itself provides Fragmentation to realize to mesh Mark file is cut, and filereader provides the api of readarraybuffer, can be by the literary composition after cutting with realization Part burst is converted into the form of buffer, and in order to carry out bit manipulation to it, this is also to pass through the first application interface for browser Webworker calculates the premise of the cryptographic Hash of each file fragmentation.Also, it should be noted the calculating of the cryptographic Hash of file fragmentation Method may be referred to the realization of md5, sha increased income, and the embodiment of the present invention is divided to the first application interface webworker calculation document The computational methods that the cryptographic Hash of piece is adopted are not specifically limited, and no longer citing describes in detail one by one herein.
This embodiment, by being divided into multiple file fragmentations to file destination, can reduce browser single treatment target literary composition The pressure of part, especially in the case that file destination data volume is very big.This embodiment is passed through to calculate the Kazakhstan of each file fragmentation Uncommon value, and the cryptographic Hash of file fragmentation is notified to server, can be true according to the cryptographic Hash of file fragmentation in order to server Whether fixed received file fragmentation correct and safety, and then has reached the accurate of received file destination in server The effect of degree.
If the data volume of file destination is very big, browser single treatment will be very painstaking, now needs target literary composition Part is divided into multiple file fragmentations,
Step s2026, browser calls data transmission interface that file is transmitted request by the process of the first application interface It is sent to server.
In the step that step s2026 provides, browser, during the process of execution the first application interface, can be adjusted With the pre-assigned data transmission interface of server, such as http data transmission interface by carry in following information at least it One file transmission request is sent to server: the identification information of file destination, the size of file destination, the number of file fragmentation Amount, the information such as the cryptographic Hash of each file fragmentation, the size of each file fragmentation, label of each file fragmentation.
It should be noted that this embodiment calls the process of the first application interface by host process, and connect in the first application The pretreatment to file destination is completed in the process of mouth, and will using the data interaction between the first application interface and server The file fragmentation of file destination is transferred to server, is capable of need not installing plug-in unit in a browser and can also realize file The purpose of breakpoint transmission, and then solve in correlation technique because mobile terminal browser does not support plug-in unit, lead to clear in mobile terminal Looking at the technical problem of the breakpoint transmission that cannot realize file in device, it is achieved thereby that simplifying browser setting, optimizing browser The technique effect of energy.
As a kind of optional embodiment, pass through what the first application interface the reception server sent in step s206 browser After confirming message, the document transmission method of this embodiment can also comprise the following steps:
