WeChat public account development-WeChat public platform message reply instance

This article mainly introduces the message reply class of the public platform developed by the public account, provides its complete example, and provides annotations to facilitate understanding and application, it is of great reference value for the development of public accounts. if you need it, you can refer to the example in this article to describe the message reply class of public platforms developed by public accounts. Share it with you for your reference. The details are as follows:

I have seen a lot of public account development code on the internet. In fact, all of them are Datong Xiaoyi. they all refer to the official demo file for modification. here I will share with you one.

The code is as follows:
