WeChat public platform message interface development and enable interface

In this WeChat public platform development tutorial, we assume that you already have the basics of PHP language program, MySQL database, computer network communication, and HTTP/XML/CSS/JS.

We will use the WeChat public account Fangbei Studio as an example to explain. See the QR code at the bottom.

This series of tutorials will guide you to complete the following tasks:

1. Apply for Baidu Cloud Platform resources

2. Enable WeChat public platform development Mode

##First article applying for server resources

Create Baidu Cloud Application

Apply for an account

Log in to http://developer .baidu.com/bae, use your email or mobile phone to register an account. Registration requires binding your mobile phone and verifying your email.

Create application

After successful registration and login, click

on the upper right side, and the following window will pop up.

Fill in any application name, select "Mobile Web Application" as the access method, and then click OK.

说明：在以下的教程中，您可以将所有我填写为pondbay的地方改为你的一个相应的名称，如果您没有想好名称，最简单的方法就是qq这两个字符+qq号码，比如方倍工作室的QQ是1354386063，那么就将"pondbay"改为"qq1354386063"

Select "Cloud Environment (BAE)",

In the new window, fill in the name of the application domain name, select PHP as the environment type, select others according to your own needs or use the default values ​​​​as shown above, and then click OK
