OAuth2.0鉴权
- 公众号可以通过微信网页授权机制，来获取用户基本信息，进而实现业务逻辑。
- 网页授权获取用户基本信息
点击修改设置授权回调域名
在微信公众号请求用户网页授权之前，开发者需要先到公众平台官网
中的开发者中心页配置授权回调域名。请注意，这里填写的是域名
（是一个字符串），而不是URL，因此请勿加[http://等协议头；]
(http://xn--%3B-nv8a14pdn5bver/)2、授权回调域名配置规范为
全域名，比如需要网页授权的域名为：www.qq.com，配置以后此域
名下面的页面[http://www.qq.com/music.html]
(http://www.qq.com/music.html) 、
[http://www.qq.com/login.html]
(http://www.qq.com/login.html) 都可以进行OAuth2.0鉴权。但
[http://pay.qq.com](http://pay.qq.com/) 、
[http://music.qq.com](http://music.qq.com/) 、
[http://qq.com无法进行OAuth2.0鉴权](http://qq.xn--
comoauth2-735sh62dwk9eysua.xn--0-k76bu98j/)3、如果公众
号登录授权给了第三方开发者来进行管理，则不必做任何设置，由第
三方代替公众号实现网页授权即可
