Referring to Fig. 2, Fig. 2 is the flow chart of processing method one embodiment that file provided by the invention uploads, it is described
Method includes:
S101, the eap-message digest for obtaining the file to be uploaded that multi-client is sent.
Specifically, when multiple client will upload same file to family's Cloud Server, each client firstly the need of point
The eap-message digest of the file to be uploaded is indescribably taken out, and family's Cloud Server, family's cloud are reported to by POST message
Server obtains the eap-message digest for the file to be uploaded that the client is sent.
The eap-message digest, i.e. Message Digest, also known as digital digest (Digital Digest), it is one
The uniquely value of a corresponding message or the regular length of text, it message is acted on by an One-way Hash Encryption function and
It generates.If message on the way changes, compared with recipient is by making a summary to the newly generated abstract for receiving message with original, just
It may know that whether message is changed.Therefore eap-message digest ensure that the integrality of message.Eap-message digest uses unidirectional Hash letter
For number by plaintext to be encrypted " abstract " at the ciphertext of a string of 128bit, this string of ciphertexts are also known as digital finger-print (Finger
Print), it has fixed length, and different plaintexts is made a summary into ciphertext, and result is always different, and it is same in plain text its
Abstract must be consistent.In this way this string abstract can become verifying in plain text whether be " original appearance " " fingerprint ".
The eap-message digest can be obtained by MD5 or SHA1 scheduling algorithm.
Wherein, MD5 refers to that Message Digest Algorithm MD5 (the entitled Message Digest Algorithm 5 of Chinese) is
The widely used a kind of hash function of computer safety field, to provide the integrity protection of message.Specifically, MD5 is
Message-Digest Algorithm 5 (Message-Digest Algorithm 5), for ensuring that information transmission is complete consistent.It is computer
One of widely used hash algorithm (and translating digest algorithm, hash algorithm), mainstream programming language generally have MD5 and realize.It will
Data (such as Chinese character) operation is another fixed-length value, is the basic principle of hash algorithm.
SHA1 refers to Secure Hash Algorithm (Secure Hash Algorithm), is primarily adapted for use in digital signature standard
Digital Signature Algorithm (the Digital Signature defined inside (Digital Signature Standard DSS)
Algorithm DSA).It is less than 2^64 message for length, SHA1 can generate one 160 eap-message digests.Work as reception
When to message, this eap-message digest can be used to the integrality of verify data.During transmission, data are likely to
It changes, then will at this time generate different eap-message digests.SHA1 has following characteristic: cannot answer from eap-message digest
Prime information；Two different message will not generate same eap-message digest, (but there is phase in the probability for having 1x10^48/mono-
Same eap-message digest is ignored when generally using).
POST message is referred to and is gone up transmitting file formation using the POST method in http protocol in data transmission procedure
Message, POST are generally used to submit data to server-side, and POST can transmit a large amount of data, so being used to on server
POST method can only be used when transmitting file.
Fig. 1-Fig. 3 is please referred to, mobile terminal A when multiple client will go up transmitting file, such as where customer end A, B and C,
When B and C will go up transmitting file, the step of customer end A and family's Cloud Server, is as follows:
A1, first customer end A create upload task；
A2, the SHA1 value for obtaining the file to be uploaded, calculate the SHA1 value of each file fragmentation；
A3, customer end A send upload request to family's Cloud Server, and SHA1, file comprising file are big in request data
The document base informations such as small, file name, fragment sum, each fragment SHA1 value.
Family's Cloud Server receives the upload request, and the message for obtaining the file to be uploaded that client is sent is plucked
It wants.When customer end B and C will go up transmitting file, customer end B and C also carry out operation identical with customer end A.
Wherein, when uploading file size more than a certain size value, big file can pass through fragment upload and breakpoint transmission.It
So being because file is excessive (such as 1G or more), it is necessary to be transmitted through in consideration using the upload of big file fragmentation and breakpoint transmission
The case where journey network interruption, has inherently had been provided with fragment upload function in the network request of Http, when the file ratio of transmission
When larger, file can be sliced (or being piecemeal) by Http agreement automatically.It has no progeny in a network, that portion that the file of 1G has uploaded
Dividing need not retransmit in network connection next time again.So big file carries out fragment when uploading, by big file, for example divide
At 1024*1024B, i.e., the piece that big file is divided into 1M is uploaded, server after the receipt, then these pieces is merged into original
File, here it is the basic principles of fragment.The client of the upper transmitting file of breakpoint transmission requirement will record the upload of each fragment
State is uploaded from breakpoint after network interruption is again coupled to.Server is judged described by filename and total the piece number
Whether file all uploads is completed.
If S102, multiple eap-message digests are that identical message is made a summary, according to the eap-message digest query service received
The file status of the file to be uploaded on device, wherein the eap-message digest received for the first time is sent by the first client.
After family's Cloud Server receives the eap-message digest of multiple client upload, if judging multiple eap-message digests to be identical
Eap-message digest judges the eap-message digest of the multi-client upload then for the eap-message digest of same file, then multiple client is wanted
The file of upload be identical file, family's Cloud Server according to the eap-message digest query service device received be it is described to
The file status of upper transmitting file, further, family's Cloud Server is according to the eap-message digest query service being firstly received
The file status of the file to be uploaded on device.
It should be noted that introducing the first client, the first client in the embodiment of the present invention to distinguish client
Do not refer to specific client, and refers to server and receive that for uploading the eap-message digest of the file to be uploaded for the first time at first
A client.
Specifically, family's Cloud Server receives the upload request that the client uploads the file to be uploaded, such as family
Front yard Cloud Server is firstly received the eap-message digest of the file to be uploaded of customer end A transmission, then customer end A is the first client
End, the eap-message digest for the file to be uploaded that family's Cloud Server is sent according to the customer end A of acquisition inquire local text
Part manages database, obtains the status information of the file to be uploaded on family's Cloud Server, and return to institute to the customer end A
State the file to be uploaded on server whether be not present, whether once on be transmitted through but non-end of transmission, whether by another visitor
Family rectify normal upper crossing, whether the file status of the already existing file to be uploaded.
S103, according to the file status, judgement needs to upload the file to be uploaded, then only handles first client
The upload request at end uploads the file to be uploaded by first client, and remaining visitor in the multi-client
The file status of the file to be uploaded is shown on the end of family.
Specifically, the server whether be not present according to the file to be uploaded in the server, whether once on
Be transmitted through but non-end of transmission, whether by another client normally upper crossing, whether already existing different conditions information,
The corresponding instruction of the file different conditions to be uploaded is sent to client.
When the server judges to be not present on the server, or once on be transmitted through but non-end of transmission described in
Upper transmitting file, then judgement needs to upload the file to be uploaded, then only handles the upload request of first client, such as family
Front yard Cloud Server receives the upload request that customer end A uploads the file to be uploaded at first, then the upload for only handling customer end A is asked
Ask, the file to be uploaded uploaded by first customer end A, at the same establish on the server file to be uploaded with
The mapping relations of other clients, such as the mapping of the server and customer end B and C send institute on the server in real time
The current file state of file to be uploaded is stated to customer end B and C, the file status includes that upload progress or upload are completed
Deng showing the upload state of the file to be uploaded by customer end B and C, but customer end B and C only show the text to be uploaded
The upload state of part, customer end B and C do not upload the file to be uploaded, only keep being in connection status with the link of server,
To realize that server only stores text document for same file, only pass through a link transmission same file.
Specifically, after family's Cloud Server receives the upload request of customer end A, step is such as please continue to refer to Fig. 1-Fig. 3
Under:
A4, family's Cloud Server judge the file for not having customer end A to be uploaded on server, then create the database of file
Information；
A5, family's Cloud Server send the file to be uploaded to customer end A and are not present, and can transmit the text to be uploaded
The instruction of part；
A6, customer end A are by the bigger file fragmentation to be uploaded；
A7, customer end A upload the fragment 1 of the file to be uploaded；
After A8, family's Cloud Server receive the fragment 1, the data of the fragment 1 are successfully written server；
A9, family's Cloud Server send file data processing successfully instruction to customer end A；
The file data processing successfully instruction that A10, customer end A are sent according to server, refreshes interface display information, more
New interface display upload progress；
A11, customer end A continue to upload remaining fragment to family's Cloud Server；
A12, customer end A upload the last one fragment to family's Cloud Server；
A13, family's Cloud Server receive the last one described fragment, and data are successfully written server；
A14, family's Cloud Server are returned to customer end A completes information；
The completion information that A15, customer end A are returned according to family's Cloud Server refreshes display interface, and the task of upload has been handled
At.
In one embodiment, described according to the file status, judgement needs to upload the file to be uploaded, then only locates
The upload request for managing first client uploads the file to be uploaded by first client, and described mostly objective
After the step of showing the file status of the file to be uploaded in remaining client in the end of family further include:
Judgement does not need to upload the file to be uploaded, then sends the current shape of the file to be uploaded on the server
State gives each client.
Specifically, when the server judges on the server by another client in addition to the multi-client
It normally uploads and has existed the file to be uploaded on the file to be uploaded or server, then judgement does not need to upload institute
State file to be uploaded, it is only necessary to establish the mapping of the file to be uploaded stored on each client and the server respectively
Relationship, the file association identical with client file to be uploaded that will be stored in each client and server, ensure that
Identical file only stores portion on the server, while having the mapping connection relationship of client and file again.Quite
The file to be uploaded server is uploaded into each client, when each client needs to obtain the file, only
The file to be uploaded need to can be realized from the acquisition on server according to the mapping connection relationship.
In one embodiment, if multiple eap-message digests are that identical message is made a summary, disappear according to receiving
Cease the file status of the file to be uploaded on digest challenge server, wherein the eap-message digest received for the first time is by the first visitor
Family end send the step of include:
According to the eap-message digest received, judge that there is no the files to be uploaded on the server；
Alternatively, judging the file to be uploaded that there is non-end of transmission on the server.
Specifically, the message for the file to be uploaded that the such as described server is uploaded according to first customer end A is plucked
It wants, inquiry local file manages database, and server passes through the filename of the file to be uploaded and the file to be uploaded
Total the piece number of file fragmentation judges state that the file to be uploaded whether there is on the server or whether upload,
The file status of the file to be uploaded includes: on the server
When the filename of the file to be uploaded is not present in the server local file management database, described in judgement
The file to be uploaded is not present in server local；
When the server local file management database is there are the filename of the file to be uploaded, and the server
Total the piece number of the file fragmentation of the upper file to be uploaded is less than fragment total tablet of the file to be uploaded in client fragment
When number, judge that the server local has the file to be uploaded of non-end of transmission.
In one embodiment, if multiple eap-message digests are that identical message is made a summary, disappear according to receiving
Cease the file status of the file to be uploaded on digest challenge server, wherein the eap-message digest received for the first time is by the first visitor
Family end send the step of include:
According to the eap-message digest received, judge the file to be uploaded by another visitor in addition to the multi-client
Family, which is rectified, is uploading the server；
Alternatively, judging there is the complete file to be uploaded on the server.
Specifically, the message for the file to be uploaded that the such as described server is uploaded according to first customer end A is plucked
It wants, inquiry local file manages database, and server passes through the filename of the file to be uploaded and the file to be uploaded
Total the piece number of file fragmentation judges state that the file to be uploaded whether there is on the server or whether upload,
The file status of the file to be uploaded includes: on the server
When the server local file management database is there are the filename of the file to be uploaded, and the server

It enables to first client, the file to be uploaded is uploaded by first client；
If it is determined that there is the file to be uploaded of non-end of transmission on the server, then it is described to upper to send upload
The instruction of the breakpoint information of transmitting file and the file to be uploaded is uploaded to first client by first client
The file to be uploaded.
Specifically, i.e. when be not present on the server or there are when the incomplete file to be uploaded, judge need
The file to be uploaded is uploaded, or needs to upload the file to be uploaded for not uploading part, to meet the service
A complete file to be uploaded is stored on device.
In one embodiment, described to judge that not needing the step of uploading the file to be uploaded includes:
If it is determined that there is the complete file to be uploaded on the server, or judge the file to be uploaded by
Another client in addition to the multi-client is being uploaded to the server, and judgement does not need to upload the text to be uploaded
Part.
Specifically, please continue to refer to Fig. 1-Fig. 3, if judging the server, there is no institutes according to the eap-message digest
File to be uploaded is stated, then sends the instruction for uploading the file to be uploaded to first client, the first client termination
After receiving the instruction for uploading the file to be uploaded, start to upload the file to be uploaded.Such as first customer end A receive institute
The file to be uploaded then is uploaded by following procedure after stating the instruction of the upload file to be uploaded of server transmission:
The file to be uploaded is carried out file fragmentation by customer end A, is sent by the file fragmentation order described to be uploaded
The data of file give the server；
The server receives the data of the file fragmentation, and whether verification file fragmentation data are correct, if correctly, institute
It states server and completes the data write-in of the file fragmentation, and return to the file fragmentation to the client and upload and successfully ring
It answers；
Customer end A continues to send next fragment, and refreshes the display of display interface upload progress.
If it is determined that there is the file to be uploaded of non-end of transmission in the server local, then send upload it is described to
To the client, the client is described from server for the instruction of the breakpoint information of upper transmitting file and the file to be uploaded
Start to upload the file to be uploaded at the breakpoint of file to be uploaded, guarantees that same file need to only upload once.
If there is customer end B and the identical file of C simultaneous transmission, then customer end B and C do not upload the file, only pass through
Link receives upload progress of the customer end A to the file to be uploaded of server transmission, and shows in customer end B and C
The upload progress.
If it is determined that the server has the complete file to be uploaded, then the server is sent described to be uploaded
File uploads successfully instruction, and, to the customer end A, the customer end A does not need already existing identical on upload server again
File, to accomplish only to store portion to identical file on the server.
If it is determined that the file to be uploaded is uploading the service by another client in addition to the multi-client
Device, such as when customer end A, B and C upload same file, and the file is just by another visitor in addition to customer end A, B and C
Family end uploads, then customer end A, B and C do not need to upload the file, and server need to only send the file to be uploaded by another
The current upload progress that one client uploads gives the customer end A, B and C, and the customer end A, B and C are only needed and server keep-alive
Link receives the upload progress of the file to be uploaded, shown on customer end A, the interface B and C the file transmitting into
Degree, it is same to guarantee that server to same file, only carries out the input operation an of file.
In one embodiment, the method also includes；
If it is determined that the file to be uploaded is being uploaded to the server, then server described in keep-alive and need simultaneously
Upload the transmission link between remaining client of the file to be uploaded；
The upload state of the file to be uploaded is sent in real time to remaining described client.
Specifically, please continue to refer to Fig. 1-Fig. 3, if customer end A is uploading the file to be uploaded, and customer end B
Upload task is created to the server with client C, is sent to family's Cloud Server and uploads the identical file to be uploaded
Request or customer end A, B and C send the request for uploading same file to server simultaneously, and the server receives first
To the upload request of customer end A, then the server process step S102 process, only handles the upload request of the first customer end A,
Return to the file to be uploaded to the customer end B and client C and go up crossing, at the same keep-alive customer end B and client C and
The transmission link of the server, i.e. server are not closed with the transmission link of customer end B and client C, wait the service
Device sends the upload progress of the file to be uploaded or uploads the uploads state such as complete, while the server is by described
Server and customer end B and the respective link of client C send heartbeat message, link described in keep-alive.
Wherein, the keep-alive, refer in Transmission Control Protocol it is long be connected to give out a contract for a project after, can within the regular hour company of holding
It connecing, i.e., usually said Keepalive (survival timer) function, the Keepalive time-out of default needs 7,200,
000milliseconds, i.e., 2 hours, detection times are 5 times.
Further, customer end A is every sends a successfully fragment, and the customer end A refreshes the display interface of upload progress,
And the server is successfully processed and completes a fragment, is just sent completely information, the customer end B to customer end B and client C
Equally refresh the file upload progress display interface to be uploaded with client C.
An identical file to be uploaded is selected to carry out please continue to refer to Fig. 1-Fig. 3, such as if it is customer end A, B and C
It uploads, if customer end A is uploading the file to be uploaded, and customer end B and C upload identical process, then customer end B
Following procedure is carried out with C:
(1) step of customer end B and server interaction are as follows:
B1, customer end B create upload task；
B2, customer end B obtain the SHA1 value of the file to be uploaded, calculate separately the SHA1 value of each file fragmentation；
B3, customer end B send upload request, and the SHA1 value of these files are sent to server by POST message；
B4, the server receive POST upload request, are detected the file to be uploaded and are being uploaded by customer end A
In；
B5, family's Cloud Server return to presently described file to be uploaded to customer end B and are transmitting, at the same send it is described to
The current upload progress of upper transmitting file；
After B6, customer end B receive the upload progress of the file to be uploaded, refresh display interface.
