Perform.Also, although logical order is shown in flow charts, in some cases, can be with suitable different from herein
Sequence performs shown or described step.
The embodiment of the present invention provides a kind of file uploading method, as shown in figure 1, this method includes：
Step 101, the content according to the first file to be uploaded, it is used to identify the first file content for the first file generated
File code.
This document code is the character string for identifying file content, can be unique character string, only when in two files
When holding identical, the file code of two files is just identical, as long as in other words two the interior of file have the ground differed
Side, the file code of both of these documents just differ.
First file includes various types of files, for example, picture, document, template image file, system file, software
Installation kit etc..
Step 102, by the file code of generation with file code list compared with the file code of upper transmitting file.
Multiple file codes are stored with file code list, file corresponding to each file code is the file uploaded,
By be in step 101 first file generated file code one by one compared with the file code in file code list, to compare
With the presence or absence of the file code identical file code with the first file in file code list.
If step 103, comparative result are the file code identical file code with generation, root in file code list be present
The first file whether is uploaded according to the condition adjudgement of the second file, wherein the second file is the file with generation in file code list
File corresponding to code identical file code.
During due to only having the content of two files identical, the file code of both of these documents is just identical, if therefore in file code
The file code identical file code with generation in list be present, the content identical with the first file has been uploaded before illustrating
Second file, then need further to judge whether to continue to upload the first file according to the state of the second file, avoid the
Two files continue the first file of upload and result in two content identical files of upload, i.e. the first file and second when intact available
File, so as to avoid uploading a large amount of content identical files.
In addition, if comparative result is that the file code identical file code with generation, explanation are not present in file code list
Before without the content identical file uploaded with the first file, then the first file is uploaded, so that first file can be used.
Further, on the basis of Fig. 1 corresponds to embodiment, whether the first text is uploaded according to the condition adjudgement of the second file
Part, including：
If the second file is in the state of damage, the first file is uploaded；If the second file is in unspoiled state,
Abandon the first file.
After upper transmitting file, file can be influenceed by various factors, such as the factor such as storage hard disk failure, after upload
File content be not be always maintained at completely it is constant, if upload after file content changed, then cannot
Normal use this document.Therefore, when needing to upload the first file, although having uploaded the content phase with the first file before
The second same file, if the second file is in the state of damage, illustrate that the second file can not then be uploaded and do not damaged by normal use
The first bad file, so use the first file.If the second file is not in the state of damage, illustrate the second file energy
Enough by normal use, then the first file need not be uploaded, use the second file, abandon the first file.
When abandoning the first file, prompt message can be returned to user, for example, display reminding is believed on display interface
Ceasing, the prompt message can be the file of content identical second of presence and the first file and not upload the first file, with
User is set to have a clear understanding of the upload situation of the first file.

If the second file is in the state of damage, the file code of generation is added in file code list；Delete second
File, the file code of the second file is deleted from file code list；If the second file is in unspoiled state, first
During the filename difference of the filename of file and the second file, the filename of the first file is added to the filename of the second file
In list.
Two file code-phases are same, mean only that the content of the not corresponding file of both of these documents code division is identical, two files
File code-phase with the filename with both of these documents it is whether identical not relation, that is to say, that two file code-phases are same, this
The filename of the other respective file of two file code divisions may be identical, it is also possible to differs.
Specifically, on the one hand, if being in the state of damage with the file of content identical second of the first file, and upload
First file, that is, the first file for replacing the second file is uploaded, the second file can have been deleted, it is literary with release second
The memory space that part takes, and the file code of the second file is deleted from file code list, avoid storing in file code list
Two identical file codes.On the other hand, if being in unspoiled state with the file of content identical second of the first file,
Although not uploading the first file, the filename of the first file is added in the list of file names of the second file, i.e., the second text
The filename of part at least two, so uploading the user of the first file can be found and first by the filename of the first file
The file of content identical second of file.For example, when party A-subscriber needs to upload the first file, the entitled " text of file of the first file
Part 1 ", before this party B-subscriber uploaded the file of content identical second with the first file, the file of the second file is entitled
" file 2 ", the second file do not damage, and do not upload the first file now, but " file 1 " adds by the filename of the first file
Into the list of file names of the second file, i.e. the second file has two filenames, is respectively " file 1 " and " file 2 ", user A
By input, " file 1 " finds the second file, and by input, " file 2 " finds the second file to user B, so as to facilitate user to search
The file of upload.
Further, before step 102, in addition to：
File corresponding to being periodically each file code in file code list regenerates file code；For file code
File corresponding to each file code in list, when the file code regenerated for this document and this document in file code list
When file code differs, the state for updating this document is in the state of damage.
When specifically, due to only having the content of two files identical, the file code of both of these documents is just identical, because
This, when the file uploaded damages, illustrates that the content of this document changes, if generating file code again for this document,
Then the file code of this document and differed in the file code regenerated and file code list.Therefore, can periodically (example
As every three days or week about) be file code list in each file code corresponding to file regenerate file code, lead to
Cross and be compared the file code of this document in the file code for this document generation again and file code list, if both are identical,
Illustrate that this document does not damage, if both differ, illustrate that damage occurs in this document.When file damages, in time more
The state of new this document, so that the file content identical file with the damage can be being uploaded afterwards.
Further, step 101 includes：
The first file content is calculated using Message Digest Algorithm 5 (Message Digest Algorithm5, MD5)
Message Digest Algorithm 5 value (i.e. MD5 values)；Text using the Message Digest Algorithm 5 value of calculating as the first file
Part code.
Further, when periodically be file code list in each file code corresponding to file regenerate file code
