I would like to implement a web application for a company in China. I need to use WeChat mini-APP to make the sign-up/login straight-forward.

Please correct my assumptions if I am wrong:

  • To implement the login of the website from WeChat, I need to use the OAuth2 protocol
  • I also need to create a WeChat developer account under a real name (need ID card or business registration stuff) if I want to diffuse the application
  • I also need to register a domain name to WeChat so that they can allow OAuth2 authentication to this domain name

Question: can I still use my localhost virtual machine to develop my server? (I didn't try but I assume WeChat will reject to create an OAuth2 token for localhost 127.0.0.1)

Or do I need to have a development domain name with a development server available from the Internet so that I can debug the OAuth2 authentication?

EDIT 1: I tried to send a HTTPS POST request https://127.0.0.1:8080 and I got an error linking to this URL https://developers.weixin.qq.com/miniprogram/dev/framework/ability/network.html

EDIT 2: I tried to send a HTTPS POST request https://192.168.1.148:8080 which correspond to my dev computer and I got the error VM17415:1 Cannot send network request to localhost. (My test phone and computer both connected to network 192.168.1.x trough WiFi)

  • Many trouble wait you.For what I can tell mini-app doesn't need to auth 2.0.It has special authorization mode.It needs support from server-side.But server-side auth needs configiure trusted doname.So it may not test localhost unless setting a proxy from server-side online to your localhost virtual machine.If you don't consider progress of authorization,to test your business code on your localhost virtual machine is avaliable. – taolu Jul 27 '22 at 02:05

The documentation is available in English on the official WebSite [1]. It is written: network APIs allow communication with LAN IP addresses. So basically, if the phone is connected to the same network as the virtual machine (i.e. WiFi), one should be able to send any kind of HTTP/HTTPS request properly.

Note that the development environment WeChat DevTools block this feature by default. In order to enable it, the user should open the Project Settings and check the box 'Does not verify valid domain names, web-view (business domain names), TLS versions and HTTPS certificates.'.
