How to Use wechat to play wechat official accounts

Provides various official and user-released code examples and code reference. You are welcome to exchange and learn how to use the wechat class to teach you how to implement most common functions, including checking weather, bus routes, automatic robot reply... Remember to give me a thumbs up!
If you do not have a public number, you can use your own number to apply for a test number. The function is quite complete.
