pc网站微信扫面二维码登陆

    在进行微信OAuth2.在进行微信OAuth2.0授权登录接入之前，在微信开放平台注册开发者帐号，并拥有一个已审核通过的网站应用，并获得相应的AppID和AppSecret，申请微信登录且通过审核后，可开始接入流程。

AppID：wxfb3**84**ea9e0

AppSecret：**

1. 第三方发起微信授权登录请求，微信用户允许授权第三方应用后，微信会拉起应用或重定向到第三方网站，并且带上授权临时票据code参数；
2. 通过code参数加上AppID和AppSecret等，通过API换取access_token；
3. 通过access_token进行接口调用，获取用户基本数据资源或帮助用户实现基本操作。
