In one embodiment, the Message Digest 5 is MD5 Message Digest 5, as shown in figure 3, the step S20
Include:
S201 fills first subfile, the file size of first subfile is made to meet the MD5 eap-message digest
The file size requirement of algorithm.
Understandably, the MD5 Message Digest 5 is a kind of Cryptographic Hash Function, and the principle is as follows: MD5 eap-message digest
Algorithm handles the data for input the MD5 Message Digest 5 with 512 groupings, each group and is divided into the grouping
16 13 seats groupings, when a data input the MD5 Message Digest 5, by filling coding and circulation to the data
After operation, export the eap-message digest of the data, the eap-message digest be it is uniquely corresponding with the data, also even input MD5 disappears
The data for ceasing digest algorithm are identical, then the eap-message digest that the data of corresponding input are exported also can be identical.
Understandably, the MD5 Message Digest 5 is a kind of Cryptographic Hash Function, if using the Cryptographic Hash Function
Operation is carried out, the Cryptographic Hash Function must be met to the length requirement of input data, therefore in the present embodiment, first to described
First subfile is filled, and the filling process is as follows: one 1 and multiple 0 is filled behind first subfile, directly
To meet the bit length of first subfile to the result of 512 complementations is 448 when, stop 0 filling, further, carrying out
To the filling information length indicated with 64 systems is added behind first subfile after filling, at this point, first son
File meets the MD5 Message Digest 5 to the length requirement of input data, in step S202 after being filled
The middle eap-message digest for generating first subfile.
Filled first subfile and the MD5 Message Digest 5 are carried out loop computation by S202, to generate
The eap-message digest of first subfile.
The loop computation process is as follows: according to preset four constants: A=0x67452301, B=0x0EFCDAB89,
C=0x98BADCFE, D=0x10325476；Preset four functions: F (X, Y, Z)=(X&Y) | ((~X) &Z)；G(X,Y,Z)
=(X&Z) | (Y& (~Z))；H (X, Y, Z)=X^Y^Z；I (X, Y, Z)=Y^ (X | (~Z)), wherein X, Y, Z are variable；Institute
It states the first subfile point and is handled with 512 for a grouping, each grouping carries out 4 round transformations, with 4 constants described above
It is calculated for starting variable, exports 4 variables again, carry out the operation of next grouping again with this 4 variables, until last
A equal operation of grouping finishes, at this point, 128 hashed values generated after 4 variables obtained joint are described first
The eap-message digest of subfile.
In one embodiment, as shown in figure 4, the step S30 the following steps are included:
S301 traverses each first subfile of the library file, detects the message of each first subfile
Whether abstract changes.
As above-mentioned, the eap-message digest is equivalent to the unique identification of first subfile, in the present embodiment, if described
First subfile of library file is modified (namely having modified code therein or other data), then corresponds to described first
The eap-message digest of subfile will also change.Therefore, it detects whether the unique identification changes, namely disappears described in detection
Whether breath abstract changes, and can obtain the first subfile modified.In the present embodiment, each first Ziwen is traversed first
Part generates the current eap-message digest of first subfile by Message Digest 5, and first subfile is worked as previous existence
At the eap-message digest that is recorded in step S20 before this with it of eap-message digest compare, to detect first subfile
Eap-message digest whether change.Namely after the completion of the projects editor, detects first subfile and currently lead to
The eap-message digest of Message Digest 5 generation is crossed, whether the eap-message digest recorded in step S20 with first subfile matches,
If matching, the eap-message digest for representing first subfile do not change, confirm that first subfile is not repaired at this time
Change；If mismatching, the eap-message digest for representing first subfile changed, and enters step S302 at this time, described in label
First subfile is the file modified.
In the present embodiment, when first subfile detection is completed (process of the detection is for example above-mentioned), i.e., pair
Next first subfile is detected, until all first subfiles have been detected and have finished.
S302 marks the described of the eap-message digest change in the eap-message digest change of first subfile
First subfile is the first subfile modified.
As above-mentioned, after the completion of the projects editor, whether the eap-message digest for detecting each first subfile becomes
More, can confirm after the completion of projects editor, each first subfile whether by user carried out modification (namely modification
Code therein or other data).
Specifically, it in the eap-message digest change of first subfile, represents after the completion of projects editor, it is described
The unique identification of first subfile is changed, further, it was demonstrated that first subfile is completed in projects editor
Afterwards, modification was carried out by user, at this point, first subfile of the eap-message digest change is marked, in order to primary server
First subfile modified is obtained in step s 40；When the eap-message digest of first subfile does not change,
It represents after the completion of projects editor, the unique identification of first subfile does not change, further, it was demonstrated that described
First subfile did not carried out modification by user after the completion of projects editor, at this point, in one embodiment, can be confirmed
First subfile is not modified, and is shown on the interface of user's edit item engineering, so that user can be more intuitive
Understand its editor content.
In one embodiment, as shown in figure 5, the step S40 the following steps are included:
S401 compares code and the modification of modified first subfile when first subfile is modified
The code of preceding first subfile confirms and obtains the code changed in modified first subfile and the change
The change of location locating in the library file of code more.
Wherein, the code of the change refers to user when editing the projects, in each described of the library file
The code modified, increase or deleted in first subfile.Understandably, the code of the change is stored in the institute modified
State in the first subfile, specifically, compare first the modified code of first subfile and first subfile into
Code before row modification, detection different code between the two, the different code is that first subfile is being modified
The code changed in the process, therefore obtain first subfile in first subfile modified and changed after being modified
Code and the change code change of location locating in the library file, can obtain it is all by modification, increase or
The code of deletion generates the more new version of the library file thus according to the code of the change, and then by the library file
More new version is uploaded to the third-party server.Understandably, because the data updated are smaller, therefore according to the generation of the change
Code generates the more new version of the library file, generates the library file more compared to according to first subfile modified
For new version, formation speed is faster.
Specifically, first subfile modified and first subfile when not modified before this are compared,
Whether the code detected in first subfile modified changes, and obtains and change in first subfile modified
Code, so as to the more new version of the library file according to the code building of the change of acquisition in step S402.
S402 looks for the change of location in the library file downloaded from third-party server, by the change bit
The code set replaces with the code of the change, to generate the more new version of the library file.
Understandably, after the completion of the projects editor, the library file in the projects modified
It cannot directly be uploaded in the third-party server and be updated, but need the code according to the change, from third party
The change of location is looked for by the library file China downloaded in server, and then the code of the change of location is replaced with institute
The code of change is stated, to generate the more new version of the library file, and then the more new version of the library file is uploaded to described
Third-party server.
S403 is uploaded to the third party by the more new version of the library file of generation by preset management path
In server.
The management path is to manage the upload and modification of dynamic link library (namely library file) in third-party server
Channel (i.e. path), it will be appreciated that ground, the third-party server management simultaneously stores the library file, at this point, to that will give birth to
At the more new version of the library file be uploaded in the third-party server, the institute in the third-party server must be passed through
Stating management path can upload, and the information in the management path can be stored in advance in the database of primary server.It will generate
The more new version of the library file be uploaded in the third-party server, can be with so that the projects are at runtime
It is deployed into the library file for meeting its functional requirement, to realize the function of the projects.
In another embodiment, after the step S402, further includes:
The more new version of the library file of generation is sent to the manager of the third-party server, for the pipe
Whether the audit of reason side receives this modification.
The third-party server is the server for managing and storing the library file, and the manager is responsible for described in management
Third-party server；Understandably, it is needing the more new version of the library file of generation being uploaded to unknown above-mentioned management road
When the third-party server of diameter, the permission by manager is needed at this time, can complete to upload, therefore in unknown above-mentioned management path
When, by the more new version of the library file of the generation be sent to the manager of the third-party server for the manager into
Row audit, to obtain the permission of the manager, is uploaded to the third-party server for the more new version of the library file.
In another embodiment, the projects also include subject executable, as shown in fig. 6, the method is also
The following steps are included:
S50 generates the message of each second subfile of the subject executable of projects by Message Digest 5
Abstract, and whether modified according to each second subfile that the eap-message digest detects the subject executable.
Wherein, second subfile refers to the document that can be directly edited in the subject executable,
It include at least one described second subfile in the subject executable.
The subject executable refers to the text for generating in primary server, and store the source files such as body code
Part, the source files such as described body code are for supporting the main execution of the software and logic；The subject executable can
To be stored in advance in the database of the primary server, can also be compiled when developing software by code management tools by user
It is generated after volume.
As above-mentioned, the eap-message digest is equivalent to unique mark of second subfile of the subject executable
Know.In the present embodiment, each second subfile of the subject executable is generated by Message Digest 5 first
Eap-message digest, and record the eap-message digest, further, after the completion of the projects editor, pass through eap-message digest
Algorithm generates the current eap-message digest of each second subfile of the subject executable, and the main body can be performed
The eap-message digest that second subfile of file is currently generated disappears with what is recorded before the projects editor completes before this
Breath abstract is compared, so that second subfile for detecting the subject executable is complete in the projects editor
Whether Cheng Hou, eap-message digest change, if the eap-message digest of second subfile of the subject executable is sent out
It changes more, can mark second subfile at this time is the file modified, to obtain second Ziwen in step S60
The code changed in part；If the eap-message digest of second subfile does not change, can confirm the subfile not by
Modification, and may be displayed on the interface of the current edit item engineering of user, to prompt user.
S60 is obtained and is changed in the subject executable modified when the subject executable is modified
Code, and the subject executable according to the code update changed in the subject executable modified.
Understandably, after the completion of the projects editor namely user complete to the exploitation of the software, modification,
When optimizing or improving, need to update the subject executable in the projects, to allow primary server by holding
The updated subject executable of row realizes the function of the projects accordingly software.Specifically, process is to obtain
Take the code changed in subject executable, and the main body according to the code update changed in the subject executable
Executable file.Wherein, the code of the change refers to that user when editing the projects, can be performed in the main body
The code modified, increase or deleted in each second subfile of file.
Understandably, the primary server is the server for managing and storing the subject executable, in this implementation
In example, the code changed in second subfile for the subject executable modified, the acquisition are obtained first
