Business terminates.
S103, after the completion of N number of blocks of files is all uploaded, server described in the client request is by N number of blocks of files weight
Combination nova determines first file into one second file, and according to the file verification value of second file and the first file
Whether upload is successful.
In above-mentioned steps S103, with reference to the specific descriptions in above-mentioned steps S102, Fig. 3 is seen, the client confirms its institute
The step whether the first file of upload is successful can specifically include：
S301, the client sends file generated request, described to ask the division for carrying N number of blocks of files suitable
Sequence, for indicating that the server reconfigures the N number of blocks of files of correspondence in N number of blocks of files buffer area according to the stripe sequence
Into one second file, returned according to the file verification value of the second file generated one first, and by the first file verification value
To client；
S302, client receives the first file verification value, and one second by it and according to the first file generated is literary
Part check value is compared, if unanimously, pointing out to upload successfully, if inconsistent, points out to upload failure.
Wherein, the first file verification value and the second file verification value are SHA1 values, are needed for verifying in client
It is whether consistent between the file that the file and server of upload are received and reconfigured, it is ensured that the accuracy of upload.
Wherein, each file piece uploads (i.e. HTTP POST requests) if because network reason causes to lose in above-mentioned steps
Lose, can re-request, rather than start anew.
Wherein, N number of task of client is the asynchronous progress of multitask, can be able to be specifically multi-thread by procedure auto-control
The specific implementations such as journey, many association's journeys.
Wherein, if some tasks carrying fail, can newly-built task replacement primary failure task, that is, re-create file
Block, the failure of ancient deed block.
Wherein, the stripe sequence can be to be made requests on, specifically by the way of HTTP POST lists to server
CSV can be used in ground, the mark of each blocks of files.
