网页获取用户授权信息

最后更新于:2022-04-01 20:00:34

思路是这样的,第一步在页面获取到授权以后的code 拿code去nodejs后台的httpserver请求 nodejs接到请求以后,拿到code去拿accessToken,然后通过accessToken获取用户信息 然后把用户信息扔给页面 后台nodejs代码: ~~~ var request = require('request'); var nodeconfig = require('./nodeconfig'); //api weixin function wx(res, postData) { console.log(getUrlVars(postData)); //微信获取用户资料第二步通过code换取网页授权access_token request.get({ url : 'https://api.weixin.qq.com/sns/oauth2/access_token?appid=wx01ca1966fe6f8a88&secret=c893b05b38&'+postData+'&grant_type=authorization_code', form : {} }, function(error, response, body) { if (!error && response.statusCode == 200) { console.log(body); var jsondata = JSON.parse(body); //第四步拉取用户信息(需scope为 snsapi_userinfo) request.get({ url : 'https://api.weixin.qq.com/sns/userinfo?access_token=' + jsondata.access_token + '&openid=' + jsondata.openid + '&lang=zh_CN', form : {} }, function(error, response, body) { if (!error && response.statusCode == 200) { var userdata = JSON.parse(body); console.log(userdata); nodeconfig.httpHeadSetting(res); res.end(JSON.stringify(userdata)); } }); } }); } exports.wx = wx; ~~~ ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-03-28_56f8eb8b759c9.jpg)
