Description
Technical Field
The application relates to a network technology, in particular to a WebApp-based website update processing method, a WebApp-based website update processing system and a storage medium.
Background
The browser requests a resource from the server for the first time, and the server returns a response header for the resource as above (Chrome). After the browser parses, the resource is cached along with the header. When the browser requests the resource again next time, the browser searches in the Cache first, and calculates whether the resource is overdue according to Expires or Cache-Control after the resource is found. If not, the cache is hit, and the cache resources are directly loaded. And if the resource packet is expired, directly loading the resource from the server, and simultaneously re-caching the new resource packet.
If the server resources are updated during the cache validity period, the browser needs to be notified to abandon the local cache. One existing solution is to add a hash fingerprint (calculated according to module contents) to an output file at a compiling stage by using Webpack, thereby implementing incremental updating of front-end static resources.
However, even if a hash fingerprint is added to the loaded resource file, such as/js/myjs- { $ hash value }. js or/js/myjs.jsv { $ hash value }, the cache update of js and css is solved, and the cache update cannot be applied to the entry index.
If the user does not strongly refresh the page (even if F5 is refreshed, different browsers differ, for example, Chrome uses cache, Edge, Firefox give up cache), the loaded html may still be cached, resulting in failure to load the latest hash fingerprint resource. A common solution to solve html caching is to set in the meta tag.
However, since the browser implementations of many manufacturers are very different, the method cannot be used in many browsers, and the cache problem still cannot be completely solved.

In the description of the present invention, reference to the description of the terms "one embodiment," "some embodiments," "an illustrative embodiment," "an example," "a specific example," or "some examples," etc., means that a particular feature or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
Part of software functions are realized based on WebApp, and if a user accesses an overdue version in a cache, operation errors of the user can be caused, and the functions cannot be completed.
To this end, referring to fig. 1 and fig. 2, the present embodiment discloses a website updating method based on WebApp, including the following steps:
s101, releasing a homepage file, a version number file and a static resource folder of a new version in a version number folder of a website root directory, wherein the static resource folder comprises a plurality of static resources.
Referring to fig. 3, the directory/root/file includes a version number folder of version V1, a version number folder of version V2, static resource folder static, homepage file index, version number file version, and description document readme. As shown in fig. 4, in this step, taking the release version V2 as an example, the content released under the folder V2 includes a static resource folder static, a home page file index, a version number file version, and a description document readme corresponding to the version V2.
S102, copying the content in the version number folder to the website root directory so as to cover the previous version of the homepage file, the version number file and the static resource folder.
The file shown in fig. 4 is copied to the root directory/root/because the names of several files corresponding to each version are the same, if there is a file corresponding to one version in the root directory itself before copying, the new version of the file will overwrite the contents in this step.
That means, as the version is released, the files in the root directory will be updated to the files corresponding to the new version, and all the folders corresponding to the old version will exist in the root directory (assuming that the folders of the old version are not deleted).
Wherein, the homepage file of any version is configured with an execution code, and when the execution code is loaded by a browser, the following steps are implemented:
s201, obtaining a version number file under the website root directory, and analyzing the obtained version number file to obtain a latest version number.
In this embodiment, all versions of the homepage file are configured with an execution code, and the execution code is used to access the root directory and obtain the version file under the root directory, so that no matter which version of the homepage is cached, the browser is not prevented from obtaining the latest version number. In this embodiment, the version number file is a JaveScript file. And the homepage file is an html file. With regard to the implementation of the execution code, the access address of the root directory may be written in the execution code. For example, the website is www.abc.com, the user accesses www.abc.com/V1, and if the current latest version is V2, the executing code will access www.abc.com first, which is equivalent to accessing the root directory, and then obtain the version number file from the root directory, and obtain the current latest version as V2.
S202, judging whether the version number in the first URL accessed by the current browser is consistent with the latest version number, if not, executing S203.
S203, replacing the version number in the first URL with the latest version number to obtain a second URL, and jumping to access the second URL.
The latest version number obtained from the above step S201 can be compared with the version number of www.abc.com/V1 in the access address, i.e. V1, and if not, the V1 in the URL is replaced by V2 to obtain a second URL, i.e. www.abc.com/V2. Then the second URL is accessed, which ensures that the latest home page is accessed by the browser each time.
It will be appreciated that if the current user accesses for the first time, the address of the access is www.abc.com, it can also get the latest home page and latest version number under the root directory and can set jump access. If the current user does not access for the first time, he has cached the V1 version locally, and also gets the latest version number, for example V2, and performs the jump. Therefore, the method is compatible with the caching mode of the current browser, the browser does not need to be modified greatly, and only the file is released and the execution code is added in the homepage file according to the method.
Through the above embodiment, when the new version is released at the website of the WebApp, the home page file, the version number file and the static resource folder of the new version are released in the root directory, the contents are covered in the root directory, the execution code is configured in the home page file, when the execution code is executed, the version number file is obtained from the root directory of the website, the latest version number is obtained, whether access skip needs to be carried out or not is judged based on whether the version number is the same as that of the first URL, and through the above mode, no matter the new version is released at any time, a user can access the latest home page file and load the latest home page file into a correct static resource file, so that the page displayed by the WebApp can be ensured to be the latest page. The method is compatible with the existing cache mechanism, ensures that the user accesses a normal homepage under the condition that the user does not forcibly refresh, avoids errors in user operation, and optimizes user experience.
In some embodiments, in S202, if the version number in the first URL accessed by the current browser is consistent with the latest version number, the static resource file is loaded according to the hash fingerprint in the homepage file loaded by the current browser;
and when the static resource file is loaded, the static resource file is loaded from a local cache static resource folder preferentially.
In this embodiment, if the current version number is the latest, it means that the static resource file cached last time, which is also a valid file in general, can be obtained from the local cache. This approach is compatible with current caching mechanisms. Network traffic may be reduced.
Referring to fig. 2, in some embodiments, after S203, further comprising:
and S204, caching the homepage file under the website directory corresponding to the second URL.
In this embodiment, since the second URL is the first access, the homepage file under the second URL may be cached. The next time the second URL is accessed, the cache may be used directly.
Referring to fig. 2, in some embodiments, after S204, further comprising:
s205, caching the static resource files in the static resource folder in the website directory corresponding to the second URL according to the hash fingerprints in the homepage file cached in the step 204.
Similarly, in this step, when the homepage file corresponding to the second URL is loaded, the static resource file in the static resource folder is cached according to the hash fingerprint in the cached homepage file, so that network transmission is reduced in the next access. The hash fingerprint is a hash code calculated by a hash algorithm according to the static resource file, and is referred to as a hash fingerprint.
Referring to fig. 5, in some embodiments, before S101, the following steps are further included:
s1001, obtaining and executing an issuing instruction.
And S1002, judging whether a website root directory exists or not, if so, executing S1003, otherwise, creating the website root directory and a version number folder specified by the release instruction, and executing S101.
S1003, judging whether a version number folder specified in the issuing instruction exists, if so, executing S101, otherwise, creating the version number folder specified in the issuing instruction under the website root directory, and executing S101.
Before the method is executed, the method also comprises a folder creation step, wherein the creation logic is that if the root directory does not exist, the root directory is indicated to be released for the first time, the root directory is created first, and then the folder with the version number corresponding to the current version is created. If a following directory exists, the description is not first published or the root directory has been artificially created. At this time, a currently issued version number folder is created under the root directory as appropriate.
In some embodiments, the homepage file is an html file, and the version number file is a JS file.
In some embodiments, the cache of the static resource file corresponding to each version number is shared during the lifecycle.
In this embodiment, the cache of the static resource file can be shared by the homepage files with different version numbers during the validity period, and there may be a small amount of changes between different version numbers, so that a part of the static resource can be reused. Therefore, the transmission of the network can be reduced, and the network bandwidth can be saved.
The embodiment discloses a website updating system based on WebApp, which comprises:
a publishing module to perform: s101, releasing a homepage file, a version number file and a static resource folder of a new version in a version number folder of a website root directory, wherein the static resource folder comprises a plurality of static resources;
a copy module to perform: s102, copying the content in the release version number folder to the website root directory so as to cover the previous version of the homepage file, the version number file and the static resource folder;
wherein, the homepage file of any version is configured with an execution code, and when the execution code is loaded by a browser, the following steps are implemented:
s201, acquiring a version number file under the website root directory, and analyzing the acquired version number file to obtain a latest version number;
s202, judging whether the version number in the first URL accessed by the current browser is consistent with the latest version number, if not, executing S203;
s203, replacing the version number in the first URL with the latest version number to obtain a second URL, and jumping to access the second URL.
