2: Log in to https://mp.weixin.qq.com

We can go to the menu "Settings" - "Development Settings" You can see the AppID of the mini program. The AppID of the mini program is equivalent to an ID card on the mini program platform. You will use the AppID in many places later (note that this must be different from the AppID of the service account or subscription account). After we have a mini program account, we need a tool to develop mini programs.
Developed according to the official tutorial https://mp.weixin.qq.com/debug/wxadoc/dev/
