wechat official account platform by selecting Settings > Account Info > Function Setting.Attention: Note that the authorization callback domain should be filled in with a domain name (which is a string) instead of a URL,
so do not add http:// or other protocol headers here.For example, if a domain name requiring webpage authorization is www.qq.com, you can perform OAuth 2.0 authentication
on the sub-domain pages http://www.qq.com/music.html and http://www.qq.com/login.html after configuration,
but cannot do so on http://pay.qq.com, http://music.qq.com, and http://qq.com.
