Example, shall fall in the protection scope of this application.
Firstly, when introducing the application, first to environment applied by file loading method provided herein and phase
It closes wording to be introduced, file loading method provided by the present application can be applicable in application environment as shown in Figure 1, including clothes
Business device, terminal, and can realize the network that server and terminal are communicated.Terminal can be, but not limited to various individual calculus
Machine, laptop, smart phone, tablet computer etc., specifically without limitation, in addition, the server can be a server
The either server cluster of multiple servers composition realizes that specifically also without limitation, which is to provide one or more
The server of a weblication, weblication are a kind of application programs that can be accessed by web, and terminal passes through browsing
The accessible weblication of device.And JavaScript is the programming language of weblication, the foot of written in JavaScript
Language namely js file are walked, is commonly used to add miscellaneous dynamic function for webpage, provides the clear of more smooth beauty for user
It lookes at effect, the corresponding function of weblication is realized by js file.
It is introduced below by the file loading method that embodiment proposes the application, is first retouched from terminal side
It states:
In one embodiment, as shown in Fig. 2, providing a kind of file loading method, include the following steps:
S10, when terminal using browser load object web application program when, to server send js file update date
Request, js file update date request for feeding back target js corresponding to the object web application program to server request
First update date of file；
In the present solution, terminal is equipped with browser, when terminal is using browser load object web application program, to
Server sends the request of js file update date.
Wherein, which requests for right to server request feedback target weblication institute
First update date of the target js file answered；, wherein first update date is the target js of current server storage
The update date of file, the server are to provide the server of the object web application program, which is should
One of weblication on server, target js file are the corresponding one of js text of the object web application program
Part.
As an example it is assumed that server B for providing weblication A, stores in server B and runs the web application journey
The js file 1,2 of sequence A timing reference, when that need to update the function of weblication A, server need to be to weblication A's
Js file 1,2 is updated, and is updated every time and have corresponding update date.
S20, terminal receive server and request the feedback information sent according to js file update date, and feedback information includes mesh
Mark first update date of js file；
In the present solution, server can be according to the js after server receives above-mentioned js file update date request
First update date of file update date request target js file, and sending to the terminal included the first update day
The feedback information of phase is to terminal, and terminal can receive the feedback letter that this includes the first update date of target js file
Breath.
S30, terminal obtain the update date of target js file, the target js file of local cache from the local cache of terminal
Update date as the second update date；
S40, terminal determine whether target js file has update according to the first update date and the second update date；
It is appreciated that receive server feedback include target js file the first update date feedback information
Afterwards, terminal device can determine the first update date of target js file by feedback information.And it is updated according to described first
Date and the second update date determine whether the target js file has update.
Wherein, the second update date was the update day of the target js file of local cache when terminal device uses browser
Phase.
It should be understood that when terminal device uses some weblication of browser execution every time, when successfully loading the web
When application program, the js file of the weblication, that is, the js file of local cache, local js would generally be cached at this time
For file due to buffered, terminal can be directly obtained the update date of the js file of local cache.
If S50, terminal determine whether target js file has update, terminal obtains the target js file updated from server,
And load the target js file of the update obtained from server.
Wherein, in the present solution, being obtained under target js file refers to directly from the server directly from server
Carry target js file.
In order to make it easy to understand, carrying out citing description to the above process here, it is assumed that have weblication A, server B, clothes
Business device B is to provide the server B of weblication A, and in terminal side, buffering has 1.0 versions of the js file 1,2, and a version is more
New date is 2018-5-11, is stored with 1.1 versions of js file 1,2 in server B, the update date of b version is 2018-6-
11, wherein 1.1 versions have increased function newly relative to 1.0 versions.Js file need to be referred to when terminal loads weblication A
1,2.At this point, terminal will be unable to using b version js file in weblication A if being loaded directly into the js file 1,2 of a version
1, function new brought by 2.And in the present solution, terminal is not direct when terminal loads weblication A with browser
The js file 1,2 of a version of using terminal side caching, but send js file to server B and update request to determine js text
The update date 2018-6-11 of part 1,2, then be compared with the update date 2018-5-11 of the js file 1,2 of local cache,
May thereby determine that js file 1,2 has update, then from server B obtain js file 1,2, thus obtain the js file 1 of b version,
2。
In one embodiment, in step S40 namely terminal is true according to first update date and the second update date
Whether the fixed target js file has update, however, it is determined that the target js file is without update, then the terminal directly acquires local
The target js file of caching is simultaneously loaded.
In order to make it easy to understand, carrying out citing description to the above process here, it is assumed that have weblication A, server B, clothes
Business device B is to provide the server B of weblication A, and in terminal side, buffering has 1.0 versions of the js file 1,2, and a version is more
New date is 2018-5-11, in server B storage and js file 1,2 1.0 versions, then similarly, obtaining in server B
The js file 1 that takes, 2 update dates are also 2018-5-11, at this point, terminal be loaded directly by browser a version js file 1,
2.It can be seen, when the provided object web application program of server does not update, terminal device is not necessarily to from clothes
The corresponding js file of device downloading object web application program of being engaged in, is loaded directly into the corresponding js of object web application program of local cache
File can effectively reduce the waste of bandwidth resources.
It in one embodiment, further include as follows when terminal loads the object web application program using the browser
Step:
S60, terminal determine the file type of the target js file, if the target js file is functionality js file,
Then follow the steps S70；
Wherein, the file type of js file is divided into front end basic framework js file and functionality js file two types,
In, front end basic framework file is basic document needed for load weblication, and functional js file is to realize web application
The js file of the function of program first determines target js before in the present solution, sending the request of js file update date to server
The file type of file, when target js file be functionality js file, then follow the steps S70.
S70, the step of sending the request of js file update date to server is triggered.
In the present solution, terminal from the server obtain target js file before, however, it is determined that target js file be function
Property js file, then the step of triggering obtains the target js file from the server, change sentence and say, however, it is determined that target js file is
Functional js file just executes to send the request of js file update date to server and sent js file update date and requests it
Follow-up process afterwards does not repeat specifically to repeat here.
In some embodiments, in step S50, the target js file for the update that terminal loads are obtained from server, comprising:
The target js file of the update is loaded using js file loading frame.Specifically, in some schemes, frame is loaded using seajs
Frame loads the target js file of above-mentioned update.Seajs loading frame be one kind follow (Common Module Definition,
CMD) the loading frame of the JavaScript module standardized, may be implemented the Development of Modular and load mechanism of JavaScript,
It is loaded, rapidly the target js file of update can be loaded by js file loading frame, improve loading efficiency.
Specifically, in some embodiments of this programme, using following code realize above-mentioned functionality js file and
The process of the target js file of the update is loaded using js file loading frame:
Seajs.config ({ map:[[/ (.*?) pawa-cswaring (.*?) (.js) $/i, " $ 1pawa-
Cswaring $ 2.js? version="+regExp]] }) //, wherein seajs.config indicates used js file load
Frame namely seajs loading frame, the key of map indicate the js file type for needing to update, and the key assignments expression of map needs to update
Document location, that is, " pawa-cswaring " find out from this document folder and meet the target js of regular expression regExp
File, and load the target js file of the update.
From the present embodiment as can be seen that since the file type of js file is divided into front end basic framework js file and functionality
Js file two types, and front end basic framework js file be in practical applications it is fixed, do not need to update, therefore, can be with
The process flow for efficiently reducing terminal, lowers the loss of terminal, to improve whole loading efficiency.
In one embodiment, as shown in figure 3, providing a kind of file loading method, include the following steps:
S100, server receiving terminal send js file update date request, js file update date request for
Server requests the first update date of target js file corresponding to feedback target weblication；
Wherein, which requests to send when loading object web application program using browser for the terminal
, which requests for requesting to feed back target js corresponding to the object web application program to the server
First update date of file, wherein first update date is the update of the target js file of current server storage
Date, the server are to provide the server of the object web application program, the object web application program be the server on its
In a weblication, target js file be the corresponding one of js file of the object web application program.
S200, server are according to the first update date of js file update date request target js file；
In the present solution, obtain target js file first updates day after receiving js file update date and requesting
Phase.As an example it is assumed that object web application program is weblication A, operation weblication A is stored in server
Timing reference js file 1,2, when the function of weblication A need to be updated, server need to weblication A js text
Part 1,2 is updated, and is updated every time and have corresponding update date.Wherein, update date 2018-5-11 works as service
After the js file update date that device receives the first update date for obtaining js file 1,2 of terminal transmission requests, service
The update date 2018-5-11 of device acquisition js file 1,2.
S300, server to terminal send feedback information, feedback information include the first update date so that terminal according to
When first update date and the second update date determine that target js file has update, the target js text updated is obtained from server
Part and the target js file for loading the update obtained from server, the update date conduct of the target js file of terminal local caching
Second update date.
As can be seen from the above technical solutions, when there is update, terminal is available and downloads to server update,
Namely newest js file, so that the js file that server side newly updates can effectively be loaded by terminal, so that newly
The function of the js file of increasing is used effectively.
In one embodiment, step S200 namely server are according to js file update date request target js file
The first update date, specifically comprise the following steps:
S201, it is receiving after js file update date requests, server determines the date information expression of target js file
Format；
It is appreciated that different js files, the date information expression format of the update date of js file is different, also
It is to say, the date information expression format of the update date of target js file also can be different, in application scenes, date information
Expression format is specifically as follows: " X1X1X1X1-X2X3-X4X5”、“X1X1X1X1.X2X3.X4X5", or are as follows: " X1X1-X2X3-
X3X4”、“X1X1.X2X3.X3X4", wherein X1For any one number of 0-9, X2For any one number of 0-1, work as X2When being 0, X3
For any one number in 1-9, work as X2When being 1, X3For any one number in 0-2；X4For any one number in 0-3, work as X4
When being 0, X5For any one number in 1-9；Work as X4When being 1 or 2, X3For any one number in 0-9；Work as X4When being 3, X5For 0-
Any one number in 1.Certainly, other than above-mentioned several date information expression formats, there can also be other date information tables
Up to format, such as: " X1X1X1X1-X2X3-X4X5X6X7: X8X9" and " X1X1X1X1-X2X3-X4X5X6X7: X8X9", wherein X1For 0-9
Any one number, X2For any one number of 0-1；Work as X2When being 0, X3For any one number in 1-9；Work as X2When being 1, X3For
Any one number in 0-2；X4For any one number in 0-3, work as X4When being 0, X5For any one number in 1-9；Work as X4For
When 1 or 2, X3For any one number in 0-9；Work as X4When being 3, X5For any one number in 0-1；X6For any one number of 0-2
Word, X6When being 0 or 1, X7For any one number, X in 0-96When being 2, X7For any one number, X in 0-48It is any in 0-5
One number, X9For any one number in 0-9.In the present solution, server can determine the date letter of target js file
Cease expression format.In application scenes, server can be at random by any one of which of above-mentioned date information expression format
Date information expression format as target js file.
S202, server are using date information expression format as the matching rule of target regular expression；
Wherein, regular expression describes a kind of mode of string matching, can be used for carrying out text matches, text
With the part for referring to that the matching rule for the regular expression found and given in given character string matches.For example,
If any such a regular expression: .A=*COMEON [0-9] { 10 }, then it represents that needs find this in text to be matched
The character string of sample, the character string are characterized in text to be matched the character string for having a COMEON, follow directly after thereafter
Some any numerical character between 10 0-9.In this case, it is assumed that text to be matched are as follows: http: //
COMEON201412547.html/~index, " COMEON201412547 " therein are exactly this canonical that can be matched
The character string of expression formula.Wherein, in the present solution, in order to search out the character string in target js file including date information,
A character string for meeting above-mentioned date information expression format is found, server is using date information expression format as target canonical table
Up to the matching rule of formula.
S203, server carry out canonical matching to target js file by target regular expression, to determine to be matched to
The character string of matching rule；
S204, server are using the character string as the first update date.
That is, by the regular expression using the date information expression format of target js file as matching rule, service
Device can determine the first update date of target js file.As can be seen that the present embodiment, which specifically proposes one kind, passes through canonical
Expression formula determines the mode of the first update date of target js file, improves the exploitativeness of the application.
In one embodiment, if the date information expression format of the target js file is X1X1X1X1-X2X3-X4X5, step
S203 namely server pass through target regular expression and carry out canonical matching to target js file, specifically include；
Server carries out canonical matching to target js file as target regular expression by following regular expression:
Var reg=/^ [1-9] d { 3 }-(0 [1-9] | 1 [0-2])-(0 [1-9] | [1-2] [0-9] | 3 [0-1]) $/,
In, var reg indicates that target regular expression ,/^ indicate the first symbol of matching string, $/expression matching string
Ending symbol, matching string are corresponding character string in target js file, [1-9] d { 3 }-(0 [1-9] | 1 [0-2])-(0
[1-9] | [1-2] [0-9] | 3 [0-1]) indicate matching rule.
In order to make it easy to understand, above-mentioned target regular expression is carried out an explanation here, wherein/^ indicates character string
With starting point；[1-9] d { 3 } expression matches continuous 4 numbers, which can be any one number in 0-9, (0 [1-9]
| 1 [0-2]) in vertical bar " | " indicate or the meaning, grouping expression can take any one number of 0-9 or 11-12 any one
Number, grouping (0 [1-9] | [1-2] [0-9] | 3 [0-1]) it indicates that any one number of 0-9 or any one number of 10-19 can be taken, or
Any one number of 20-29 or any one number of 30-31.In general, the purpose of above-mentioned target regular expression is from target
It is looked in js file and meets " X1X1X1X1-X2X3-X4X5" character string, such as: 2018-05-31 is then meeting above-mentioned target just
The then matching rule of expression formula.
It should be noted that in addition to this, according to the difference of the date information expression format of target js file, there are also other
To target js file carry out regular expression matching mode, specifically without limitation, such as: if the date of target js file
Information representation format is X1X1X1X1.X2X3.X4X5, regular expression is carried out to target js file using following regular expression
Match:
Var reg=/^ [1-9] d { 3 } (0 [1-9] | 1 [0-2]) (0 [1-9] | [1-2] [0-9] | 3 [0-1]) $/.
It should be understood that the size of the serial number of each step is not meant that the order of the execution order in above-described embodiment, each process
Execution sequence should be determined by its function and internal logic, the implementation process without coping with the embodiment of the present application constitutes any limit
It is fixed.
