Embodiment
The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although the disclosure is shown in accompanying drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here Limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure Completely it is communicated to those skilled in the art.
The embodiments of the invention provide a kind of system of data transfer, as shown in figure 1, system includes：The kimonos of client 11 Business device 12；Wherein,
If client 11 is used to communicate to connect during upper transmitting file to interrupt, according to the data letter sent Breath, it is determined that upload interruption position, and after communication connection recovers normal, carry upload interruption position from upload at interruption position after Continuous upper transmitting file；
If server 12 is used to communicate to connect during file is received to interrupt, according to the data letter received Breath, it is determined that receive interruption position, and after communication connection recovers normal, receive and upload interruption position and from uploading interruption position Continue the file uploaded in place；
Server 12 is additionally operable to, according to receiving interruption position and uploading interruption position, judge whether to have uploaded but not Successful missing data is uploaded, if missing data be present, missing is determined according to receiving interruption position and uploading interruption position The shortage of data scope of data, shortage of data scope is sent to client 11；
Client 11 is additionally operable to receive shortage of data scope, and uploads missing corresponding to shortage of data scope to server 12 Data.
The system of data transfer provided by the invention, can be after server and client establish communication connection, server Receive the file that client uploads；When communication connection is interrupted during receiving this document, server can basis The data message received, it is determined that receiving interruption position；After communication connection recovers normal, server receives what client uploaded Upload terminal location and the file for continuing to upload from the upload extreme positions, the reception that then server determines according to itself The upload interruption position that interruption position and client determine, judges whether to have uploaded but does not upload successful missing number According to when it is determined that missing data be present, server determines the number of missing data according to interruption position and upload interruption position is received Client is sent to according to range of loss, and by the shortage of data scope, so that client will be corresponding according to the shortage of data scope Missing data be uploaded to server.It follows that on when being interrupted with needing again uplink to be connected in the prior art The whole file fragmentation passed is compared, and client of the invention only need to again upload and upload but do not uploaded successful data, Successful any data have been uploaded without uploading again, so as to reduce the data volume of re-transmission, and have caused what server received The data repeated are not present in data, and then saves flow, improve the efficiency of file upload.
Further, the embodiments of the invention provide a kind of method of data transfer, this method to be mainly used in server Side, as shown in Fig. 2 this method mainly includes：
201st, after communication connection is established with client, the file that client uploads is received.
When client desires access to server, it is necessary to send communication connection request to server, and receiving service After the communication connection response that device is sent, successful connection is determined；After server and client establish communication connection, client can be with Being uploaded to server needs the file that uploads, and in order to allow server to identify which file the file of upload is, client While file data is uploaded, the file identification for unique mark file can be also uploaded.Wherein, file identification can be by visitor Family end is directly distributed, and can also be distributed indirectly by server.Server is that the specific implementation of file distribution file identification can Think：Client first sends file identification distribution request before upper transmitting file to server；Server receives this document mark Can be that file to be uploaded is randomly assigned a file identification after knowing distribution request, can also be according to default allocation rule, to treat Upper transmitting file distributes a file identification, such as is followed successively by different clients file to be uploaded according to order from small to large and enters Line number.
It should be noted that agreement used in being communicated between client and server can be HTTP (Hypertext Transfer Protocol, HTTP), such as HTTP2.0, or other agreements, do not limit herein.
Interrupted if the 202, being communicated to connect during file is received, according to the data message received, it is determined that Receive interruption position.
Specifically, on user end to server during transmitting file, may be consumed because of network failure, terminal power The reason such as most causes the communication connection between client and server to interrupt.After recovering normal for the ease of communication connection, Determine whether to upload again when client continues upper transmitting file and uploaded but do not uploaded successful data, server is it is determined that logical After letter connection is interrupted, it can determine to receive interruption position according to the data message on this document having been received by present, When interrupting, the offset of the data that receive for the last time in whole file, subsequently to be continued according to client The data message of upload determines whether there is missing data.
It should be noted that in actual applications, client and server judges whether communicate to connect (i.e. network connection) Normal method has a variety of.For example, after client and server establish connection, client regularly can be sent to server side Heartbeat packet, to indicate that it is online, server also can reply a response message after receiving heartbeat packet to client, to indicate it Receive heartbeat packet；If server does not receive the heartbeat packet of client transmission in preset time period, server determines to connect Interruption is connect, if server is over time, and can enough receives the heartbeat packet of client transmission, then server determines that connection is extensive It is multiple normal；If client does not receive the response message of server return in preset time period, client is determined in connection Disconnected, if client is over time, and can enough receives the response message of server return, then client determines that connection recovers Normally.
203rd, after communication connection recovers normal, upload interruption position that client uploads is received and from uploading interrupt bit Continue the file uploaded in the place of putting.
Wherein, it is that client determines according to the data message sent, with receiving interruption position pair to upload interruption position The position answered, i.e., communication connection interrupt when, client last time to server send data in whole file Offset.After communication connection is interrupted, client can determine to upload interruption position according to the data message sent, After connection to be communicated recovers normal, the upload interruption position can be carried and continue to upload this document at the upload interruption position.
204th, according to receiving interruption position and uploading interruption position, judge whether to have uploaded but do not upload successfully Missing data.
Specifically, server may determine that whether reception interruption position and upload interruption position are identical；If receive interrupt bit Put identical with uploading interruption position, it is determined that receive and missing data is not present between interruption position and upload interruption position；If connect It is different from uploading interruption position to receive interruption position, it is determined that receive between interruption position and upload interruption position and missing number be present According to.
If missing data the 205, be present, the number of missing data is determined according to interruption position and upload interruption position is received According to range of loss.
When server, which determines to receive, missing data be present between interruption position and upload interruption position, server can be true The shortage of data scope of the fixed missing data is " (receiving interruption position, upload interruption position) ".If for example, receive interruption position For 50KB, upload interruption position is 54KB, then shortage of data scope is (50KB, 54KB).
206th, shortage of data scope is sent to client, so that client uploads missing number according to shortage of data scope According to.
In actual applications, during the entire process of upper transmitting file, communication connection may occur once to interrupt incessantly, therefore There may be multiple shortage of data scopes.In this case, server can be just vertical with one data range of loss of every determination The shortage of data notice for carrying shortage of data scope is sent to client, so that client is continued based on upload interruption position While uploading follow-up data, separately start a thread, upload missing data；It can also be uploaded in last data of file After success, all shortage of data scopes are disposably sent to client, is concentrated so as to client and uploads the data lacked.
You need to add is that the mode for the breakpoint transmission that the embodiment of the present invention is provided not only goes for upper transmitting file Scene in, can be applicable to download file scene in.
The method of data transfer provided in an embodiment of the present invention, can after server and client establish communication connection, Server receives the file that client uploads；When communication connection is interrupted during receiving this document, server can The data message received with basis, it is determined that receiving interruption position；After communication connection recovers normal, server receives client The upload terminal location of upload and the file for continuing to upload from the upload extreme positions, then server is according to itself determination The upload interruption position for receiving interruption position and client and determining, judge whether to have uploaded but do not upload and successfully lack Data are lost, when it is determined that missing data be present, server determines missing data according to interruption position and upload interruption position is received Shortage of data scope, and the shortage of data scope is sent to client, so that client will according to the shortage of data scope Corresponding missing data is uploaded to server.It follows that interrupted with needing again uplink to be connected in the prior art Shi Shangchuan whole file fragmentation is compared, and client of the invention only need to again upload and upload but not upload successful data i.e. Can, successful any data have been uploaded without uploading again, so as to reduce the data volume of re-transmission, and server have been received Data in be not present repeat data, and then save flow, improve file upload efficiency.
Further, in order that server is when communication connection is interrupted, it can quickly and accurately determine to receive and interrupt Position, the embodiments of the invention provide following processing method：From starting to receive the data that client uploads, server will be from this The file fragment that secondary communication connection recovers to receive between normally interrupting to communication connection next time is (including from starting to connect Receive data file fragment for receiving between interrupting for the first time) and the missing data that receives every time corresponding to file Fragment is respectively written into different storage address；By storage address, the start bit of each file fragment corresponding to each file fragment Put and each the corresponding relation between the size of file fragment is stored into index file corresponding to file, wherein, from this The original position that communication connection recovers the file fragment received between normally being interrupted to communication connection next time is logical for this Letter connection occurs to upload interruption position corresponding to interruption.
Specifically, when server initially receives the data of client upload, data storage that server will receive To the first storage address, an index file is then generated, by the first storage address, the original position of the first file fragment (i.e. 0) store into index file；When communication connection is interrupted for the first time, server is by the first file fragment received Size is stored into index file；After communication connection recovers normal, server continues to the data of client upload, and will Then second of data storage received updates index file, i.e., by the second storage address, the second file to the second storage address The original position (the upload interruption position interrupted for the first time) of fragment is stored into index file；If server determines for the first time Interrupt and occur to missing data between first time the interruption ends be present, then shortage of data notice can be issued to client, this In the case of, server can also receive the missing data of client upload, and after missing data is received, server will can lack Data storage is lost to the 3rd storage address, then updates index file, i.e., by the 3rd storage address, the original position of missing data (the reception interruption position interrupted for the first time) and the size of missing data are stored into index file.According to above-mentioned storage side Each communication connection is recovered the file fragment that is received between normally being interrupted to communication connection next time and often by formula successively File fragment corresponding to the secondary missing data received is respectively written into different storage address, and corresponding renewal index file, with Just the foundation for judging to receive interruption position is provided for interruption next time, and ff approach is provided for subsequent download file.
After index file is obtained, server can quickly and accurately determine to receive interruption position, tool using index file Body determines that method is：Server according to stored in index file from last time communication connection recover normally to this communication link sending and receiving The original position of file fragment and the size of file fragment received between raw interruption, determine that this is interrupted in corresponding receive Disconnected position.Wherein, interruption position=last time communication connection is received to recover to receive between normally interrupting to this communication connection File fragment original position+file fragment size.
Exemplary, if last time communication connection recovers the file piece received between normally being interrupted to this communication connection The original position of section is 100KB, and the size of file fragment is 200KB, then receiving interruption position corresponding to this interruption is 300KB。
Further, in order to further improve transfer efficiency on file, client can carry out burst processing to whole file, Then start multiple threads while upload multiple file fragmentations, and above-mentioned breakpoint transmission is respectively adopted for each file fragmentation Mode is uploaded.Specifically, after client carries out burst processing to file, server can receive client upload simultaneously Multiple file fragmentations mark and each file fragmentation mark corresponding to file fragmentation；Then distinguish for each file fragmentation Perform above-mentioned steps 102-106.Wherein, the upload interruption position in each file fragmentation and reception interruption position can be at this Offset in file fragmentation.
It should be noted that because after burst processing is carried out to file, each file fragmentation is regarded one by client New file is uploaded to server, so server can be directed to each file fragmentation during each file fragmentation is received Index file corresponding to generation respectively, the upload information for separate records respective file burst.For example, if client is by file File fragmentation 1, file fragmentation 2, file fragmentation 3 and file fragmentation 4 are cut into, then subsequent server can generate corresponding respectively Index file, i.e. the manipulative indexing file 1 of file fragmentation 1, the manipulative indexing file 2 of file fragmentation 2, the manipulative indexing of file fragmentation 3 text Part 3 and the manipulative indexing file 4 of file fragmentation 4.
Further, after file uploads successfully, other clients may need to download this document.In actual applications, Downloading the specific implementation of this document can be：Server receives the download request for the download file that client is sent；Obtain Index file corresponding to file；If index file corresponding to file is one, according to the file fragment recorded in index file The sequencing of original position and the storage address of respective file fragment, be successively read each file fragment, and according to Reading order carries out file splicing；If index file corresponding to file is at least two, the order identified based on file fragmentation, The sequencing of the original position of the file fragment recorded successively in the index file according to corresponding to file identification and corresponding text The storage address of part fragment, each file fragment is read, and file splicing is carried out according to reading order；By spliced file It is sent to client.
Exemplary, client needs corresponding 2 index files of file downloaded, wherein, the respective file point of index file 1 Piece 1, particular content is as shown in table 1, and the respective file burst 2 of index file 2, particular content is as shown in table 2.In this case, Server can first be successively read address 4, address in address 1 in index file 1, address 3, the data in address 2, index file 2 6th, the data in address 5, then these data is spliced according to reading order, spliced file is finally sent to visitor Family end.

601st, receive client and continue the data of upload and the start bit of this upload data according to interruption position is uploaded Put.
After server and client establish communication connection, client can upload the file for needing to upload to server, And in order to allow server to identify which file the file of upload is, client is while file data is uploaded, also in meeting Pass the file identification for unique mark file.Wherein, file identification can directly be distributed by client, can also be by server Distribution indirectly.Agreement used in being communicated between client and server can be HTTP, such as HTTP2.0, or its His agreement, is not limited herein.
On client is received during transmitting file, the reason such as can usually exhaust because of network failure, terminal power makes The communication connection obtained between client and server is interrupted, and during broken communication connection, client can not be sent out Any data, server can not also receive any data；After communication connection recovers normal, client can be according to itself Upper transmitting file is continued in the interruption position that the data message of transmission determines, i.e., after communication connection recovers normal, server can connect Receive client and continue the data of upload and the original position of this upload data according to interruption position is uploaded.
It should be noted that server receive client this upload data original position can be upload interrupt bit Put, can also or be any position after interruption position is uploaded.Wherein, no matter original position is to upload interrupt bit Put, or upload the position after interruption position, because follow-up data from the position are not transmitted across, so being not in The phenomenon of data has been sent out in repetition.Also, if original position has sent to upload interruption position when this interruption is not present But when not sending successful data, client passes data without mending；If original position is the position after upload interruption position, No matter this is interrupted with the presence or absence of having sent but not sent successful data, and client, which is required to mend, passes data, i.e., at least needs Benefit passes and (uploads interruption position, original position) data in the range of this.
602nd, according to original position and the data message received, shortage of data scope is determined.
This step can be specifically refined as：
(1) according to the data message received, it is determined that receiving interruption position.
Wherein it is determined that the opportunity for receiving interruption position, which can be communication connection, occurs Interruption period between The following article, communication connection is also thought After recovering normal.
(2) by the difference between original position and reception interruption position, shortage of data scope is determined.
Specifically, first judge whether original position is identical with receiving interruption position；If original position is with receiving interruption position It is identical, then server determine this interrupt be not present uploaded but do not uploaded successful missing data；If original position is with receiving Interruption position is different, then server determines that this interruption has missing data, and the shortage of data scope of missing data is (to connect Receive interruption position, original position).
603rd, shortage of data scope is sent to client, so that client uploads missing number according to shortage of data scope According to.
The specific implementation of this step is consistent with above-mentioned steps 206, will not be repeated here.
The method of data transfer provided in an embodiment of the present invention, it can be communicated on client is received during transmitting file In the case that connection is interrupted, after communication connection recovers normal, client is first received according to uploading on interruption position continues The original position of the data of biography and this upload data, then according to original position and the data message received, it is determined that Shortage of data scope, shortage of data scope is finally sent to client, so that client will be right according to the shortage of data scope The missing data answered is uploaded to server.It follows that when being interrupted with needing again uplink to be connected in the prior art The whole file fragmentation uploaded is compared, and client of the invention only need to again upload and upload but not upload successful data i.e. Can, successful any data have been uploaded without uploading again, so as to reduce the data volume of re-transmission, and server have been received Data in be not present repeat data, and then save flow, improve file upload efficiency.
Further, from above-described embodiment, the key that server determines whether there is missing data is to be uploaded Interruption position and reception interruption position, so accurately and rapidly determining that upload interruption position and reception interruption position are of crucial importance. In order that server can quickly and accurately determine to receive interruption position, server can be from when communication connection is interrupted The data for starting to receive client upload rise, and will normally be communicated to connect from this communication connection recovery to next time between interrupting File fragment corresponding to the file fragment received and the missing data received every time is respectively written into different storage address； By between the size of storage address, the original position of each file fragment and each file fragment corresponding to each file fragment Corresponding relation store into index file corresponding to file.
Further, after index file is created, according to the data message received, it is determined that receiving the specific of interruption position Implementation can be：Recover according to being stored in index file from last time communication connection in normally occurring to this communication connection The original position of file fragment and the size of file fragment received between disconnected, determine that this receives interrupt bit corresponding to interrupting Put.

Wherein, uploading interruption position is determined according to the data message sent, and uploads interruption position determination During opportunity can be broken communication connection, or upload is interrupted after recovery normally.
702nd, the original position of this data to be uploaded is determined according to upload interruption position.
This step can be specifically refined as：Interruption position will be uploaded and be defined as original position；Or it will be located to upload and interrupt Any position after position is defined as original position.
Need to illustrate, no matter original position is uploads the position after interruption position, or upload interruption position, The data for repeating to upload are not present in the data for continuing to upload from original position, and are not made due to there may be certain interruption Sent into data but do not sent successful situation, upload missing can be reduced so interruption position will be uploaded and be set to original position The number of data, so as to improve upper transfer efficiency.
703rd, carry original position and continue upper transmitting file from original position.
Specifically, after each communication disruption recovers normal, client is when to server up transfer file, except based on certainly The interruption position that body judges continues to upload outside data, also the original position of the file fragment uploaded every time can be reported into service Device, the file fragment original position uploaded according to client so as to server are come compared with the interruption position that itself judges Judge whether missing data.
704th, the shortage of data scope that the reception server is sent.
Wherein, shortage of data scope can be by server according to the original position received and the data message received And obtain, i.e., after server receives the original position of client upload, first determined according to the data message received in reception Disconnected position, then by the difference between original position and reception interruption position, determine shortage of data scope.
It should be noted that because server may issue shortage of data scope for Current interrupt in time, it is also possible to After last data of file are received, property issues shortage of data scope caused by all interruptions again, so client The shortage of data scope disposably received may only have one, it is also possible to have multiple.
705th, missing data corresponding to shortage of data scope is uploaded to server.
Wherein, in order to enable the server to know which segment data the missing data that client uploads belongs to, so as to follow-up During other client downloads this documents, file data order is avoided to be disturbed, client is uploading shortage of data model to server Corresponding to enclosing during missing data, shortage of data scope can be carried, can also only carry the original position of shortage of data scope.
