This article mainly explains "how Mini Program jumps to different background environments according to referer". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how Mini Program jumps to different background environments according to referer".

1. Question:

When developing Mini Program, there are 4 versions (development, experience, review, formal). So different environments have to request different backgrounds. In particular, the audit version, because there is also Wechat review, if the request is incorrect, it will be failed. Because the production environment corresponds to the old background version, the audit version can be neither transferred to the background production environment nor skipped to the development environment.

We request / prod for the convenience of production and review of both versions of Mini Program. Here, it is necessary to distinguish where the real request comes from production and audit.

Second, the solution.

If Wechat sends a request for wx.request to our server, it will bring a header parameter of referer. The format is as follows:

Https://servicewechat.com///page-frame.html

The Mini Program appId that sent the request is the version of Mini Program.

The version value in the development, experience, and audit version is 0, and the version value in the development tool is devtools.

The version value of the official version is a positive integer greater than 0, indicating how many times this Mini Program has been posted to the official version. Examples are as follows:

Development version: https://servicewechat.com/ Mini Program appId/0/page-frame.html experience version: https://servicewechat.com/ Mini Program appId/0/page-frame.htmldevtools: https://servicewechat.com/ Mini Program appId/devtools/page-frame.html official version: https://servicewechat.com/ Mini Program appId/6/page-frame.html III, solution. Server selection is made through nginx. 1. Define a variable foo, configure a map, and map http_referer to foo. Map $http_referer $foo {default "prod"; ~ ^ https://servicewechat.com/[^/]+/0/(.*)$ "dev"; ~ ^ https://servicewechat.com/[^/]+/devtools/(.*)$ "dev";} 2, configure the server. Upstream dev {server localhost:7777;} upstream prod {server localhost:9999;} 3, use the foo variable in location to navigate to the correct address.

Here I use add_header to output the foo variable as a test.

Location / {# set $foo "$http_referer"; add_header wkfoo 'foo: $foo "$http_referer"; proxy_pass http://$foo;} 4, test it. Curl-H 'Cache-Control: no-cache'-I "https://xxx.xxx.com/prod/xxx? Parameter 1roomxxx & parameter 2=xxx "- referer" https://servicewechat.com/xxx/devtools/page-frame.html"curl-H 'Cache-Control: no-cache'-I "https://xxx.xxx.com/prod/xxx? Parameter 1roomxxxx & parameter 2=xxx "--referer" https://servicewechat.com/xxx/0/page-frame.html" thank you for reading, that's how Mini Program jumps to different background environments according to referer ", after the study of this article, I believe you have a deeper understanding of how Mini Program redirects to different background environments according to xxxx, and the specific use needs to be verified in practice.
