微信登录授权流程

1、准备工作,需要在微信开放平台申请一个应用,需要网站域名备案过。

得到:appid和secret两个重要参数,这边域名涉及到后面微信回调。

 

 

2、时序图

 

 

 3、主要步骤四点

一)根据appid和回调redirect_uri生成二维码图

https://open.weixin.qq.com/connect/qrconnect?appid=wx410c26fd9ec1a11e&redirect_uri=http://www.xiangxueketang.cn/wx/callback&response_type=code&scope=snsapi_login&state=STATE#wechat_redirect

二)用户扫完二维码图,确认后,微信会回调redirect_uri对应的地址,把code传过来

 

 

 三)根据code,appid,secret换取token

https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code
返回结果
{ 
"access_token":"ACCESS_TOKEN", 
"expires_in":7200, 
"refresh_token":"REFRESH_TOKEN",
"openid":"OPENID", 
"scope":"SCOPE",
"unionid": "o6_bmasdasdsad6_2sgVt7hMZOPfL"
}

  

四)根据token得到用户的信息

https://api.weixin.qq.com/sns/userinfo?access_token=ACCESS_TOKEN&openid=OPENID
返回结果:
{
"openid":"OPENID",
"nickname":"NICKNAME",
"sex":1,
"province":"PROVINCE",
"city":"CITY",
"country":"COUNTRY",
"headimgurl": "https://thirdwx.qlogo.cn/mmopen/g3MonUZtNHkdmzicIlibx6iaFqAc56vxLSUfpb6n5WKSYVY0ChQKkiaJSgQ1dZuTOgvLLrhJbERQQ4eMsv84eavHiaiceqxibJxCfHe/0",
"privilege":[
"PRIVILEGE1",
"PRIVILEGE2"
],
"unionid": " o6_bmasdasdsad6_2sgVt7hMZOPfL"

}
