Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Fig. 1 shows a kind of photograph document handling method suitable under weak net environment of one embodiment of the invention offer, packet
It includes:
S11, the target MD5 value for receiving Target Photo file and corresponding multiple fragments, the fragment are to the target
Picture in picture file carries out the data slot that fragment processing obtains；
S12, multiple fragments are subjected to splicing, obtain splicing picture file；
S13, the splicing MD5 value for obtaining the splicing picture file, by the splicing MD5 value and the target MD5 value into
Row compares, and if they are the same, then the Target Photo file is uploaded or downloaded successfully.
For step S11- step S13, it should be noted that in embodiments of the present invention, either uploading pictures are still
Download pictures, either client or server-side (are not to continue with last time when generating a new picture file behavior each time
Unfinished picture backup), will generate picture file object (pic_bak) mono- picture file of include (may but not
It is limited to) an at least picture (picture).For picture, picture is one for belonging to any image file (pic_bak)
Object picture.A picture (physically same) on mobile phone, can appear in multiple picture files (pic_bak) object
In, and represent different pictures (picture) object.Restore every time, is in fact exactly some picture file restored
(pic_bak) all pictures (pictures) object of object.
Under weak net environment, picture file upload or downloading before, need to the picture in the Target Photo file into
Row fragment processing obtain data slot (not necessarily physically really tear open, 20KB can be read from full picture every time
Data slot come out), an any of them data slot is just called fragment (chunk).Under weak net environment, each fragment
Size is in the range of 10KB~100KB.
Under weak net environment, system only supports most 99999999 fragments at present, so the Target Photo file
Size is less than 1000GB.
In embodiments of the present invention, when picture file is downloaded, executing subject can be client, and client can receive
The target MD5 value of Target Photo file and corresponding multiple fragments.When picture file uploads, executing subject can be service
End, server-side can receive Target Photo file target MD5 value and corresponding multiple fragments.
In embodiments of the present invention, multiple fragments are subjected to splicing, obtain splicing picture file, obtains the splicing
The splicing MD5 value is compared by the splicing MD5 value of picture file with the target MD5 value, if they are the same, then the target
Picture file is uploaded or is downloaded successfully.
In embodiments of the present invention, if the splicing MD5 value and the target MD5 value be not identical, by multiple fragments into
Capable splicing again, obtains new splicing picture file.Then the acquisition of MD5 value is carried out to new splicing picture file, then will
The splicing MD5 value is compared with the target MD5 value.So circulation, until splicing MD5 value and the target MD5 value phase
With until.
A kind of photograph document handling method suitable under weak net environment provided in an embodiment of the present invention, by receiving target figure
Multiple fragments are carried out splicing by the target MD5 value of piece file and corresponding multiple fragments, are obtained splicing picture file, are obtained
The splicing MD5 value for taking the splicing picture file, the splicing MD5 value is compared with the target MD5 value, if they are the same,
Then the Target Photo file is uploaded or download successfully, thus realization the efficient progress picture upload of weak net environment or under
It carries.
