The segmental information corresponding with file to be downloaded is then obtained according to download request, segmental information is finally sent to terminal.Wherein,
Segmental information can be that server prestores or generate multiple cutting files by carrying out cutting to file to be downloaded, so
Enter what row format description was generated to one in file to be downloaded and multiple cutting files afterwards.
Wherein, segmental information includes：File to be downloaded name, the hash check code of file to be downloaded, at least one cutting text
The download address of part.
File to be downloaded name is used to terminal downloads cutting file and reverts to the filename after merging after merging treat
Download filename.
The hash check code of file to be downloaded, hash check generation is carried out using sha-256 algorithms to file to be downloaded and breathed out
Uncommon check code, compared with the hash check code for the file to be downloaded for merging generation with terminal, so that it is determined that terminal whether
The file needed for user is downloaded in success.
The download address of at least one cutting file, for terminal according to the download address of at least one cutting file come really
The download address of other fixed all cutting files.
S230, cutting file corresponding with file to be downloaded is downloaded according to segmental information.
In practical application, segmental information can also include the number of cutting file, corresponding to each cutting files of S132
Download address is determined according to the download address of file to be downloaded, is by the text to be downloaded in file to be downloaded download address
What the filename that part name replaces with each cutting file obtained, after terminal receives segmental information, it can be believed according to cutting
The download address of the cutting file included in breath and the number of cutting file determine the download address of all cutting files, such as
The download address of cutting file is http//static.iqiyi.com/aiqiyi015.zip, and the number of cutting file is 30
It is individual, it can determine that the download address of all cutting files is http//static.iqiyi.com/ based on this
Aiqiyi000.zip ... http//static.iqiyi.com/aiqiyi029.zip, all cutting files are then downloaded, finally
All cutting files are merged into the generation file to be downloaded to be downloaded of user.
With reference to above-described embodiment, in an embodiment of the present invention, reference picture 4, S230 can specifically include：
S231, the download address of at least one cutting file in the segmental information determine all cutting texts successively
The download address of part.
After terminal gets the download address of at least one cutting file in segmental information, according at least one cutting text
The download address of part determines the download address of all cutting files.Corresponding in S132, because the download address of cutting file is
Server by file to be downloaded cutting be no more than multiple cutting files of predetermined threshold value after, according to the download of file to be downloaded
What location determined successively, then when terminal obtain segmental information included in cutting file download address for http//
, can be true successively according to the download address of the cutting file based on this terminal during static.iqiyi.com/aiqiyi015.zip
The download address of other fixed all cutting files, since http//static.iqiyi.com/aiqiyi000.zip, finally
When terminal determines to arrive http//static.iqiyi.com/aiqiyi030.zip, find not corresponding in server
Aiqiyi030.zip cutting file, then terminal can be determined that the download address of all cutting files for http//
static.iqiyi.com/aiqiyi000.zip…http//static.iqiyi.com/aiqiyi029.zip。
S232, all cutting files are downloaded according to the download address of all cutting files.
After terminal determines the download address of all cutting files, institute is downloaded according to the download address of all cutting files
There is cutting file.
In another example of the embodiment of the present invention, terminal downloads cut corresponding with file to be downloaded according to segmental information
During single cent part, specifically, cutting file corresponding with file to be downloaded can be downloaded by the download thread of predetermined number.
Terminal can be downloaded after determining the download address of all cutting files by the download thread of predetermined number.Phase
Answer, terminal can be defaulted as two download threads while be downloaded, can so reduce download All Files needed for when
Between.
Optionally, before downloading cutting file corresponding with file to be downloaded by the download thread of predetermined number, terminal
It can also judge whether the number of cutting file is more than predetermined number threshold value；If the number of cutting file is more than predetermined number threshold
Value, then increase the value of predetermined number.
