Django后台通过微信小程序传过来的code获取用户唯一身份识别openid

• app.js

//app.js
App({
  onLaunch: function () {
    this.globalData = {
      userInfo: null,
      serverAddr: 'http://127.0.0.1:8000',
      apiVersion: "/api/v1.0",
      staticDir: "/static",
      authType:4,
      code: ""
    }
    // 登录
    let that=this;
    wx.login({
      success(res) {
        //js调用登陆命令获取到code
        if (res.code) {
          that.globalData.code = res.code
          //通过code调用自己服务接口获取到openid
        } else {
          console.log('登录失败！' + res.errMsg)
        }
      }
    })
    //获取用户信息
    wx.getSetting({
      success: res => {
        if (res.authSetting['scope.userInfo']) {
          wx.getUserInfo({
            success: res => {
              this.globalData.userInfo = res.userInfo
              if (this.userInfoReadyCallback){
                this.userInfoReadyCallback(res)
              }
            }
          })
        }
      }
    })
  },
  onShow:function () {
  }
})


// "iconPath": "",
// "selectedIconPath": ""

• index.js

//index.js
const WxParse = require('../../wxParse/wxParse.js');
const app = getApp();
var gloData = app.globalData

• app.js 中调用wx.login({})获取获取登录code
• index.js中请求授权，然后获取用户信息，并提交后台处理

• appid、以及secret通过微信公众号获取，然后作者设置在了Django setting中
  APPID = "wx秘密09"
  SECRET = "6c秘密不给看7031d"

import requests

from django.conf import settings


class OpenidUtils(object):

    url = "https://api.weixin.qq.com/sns/jscode2session"
    appid = settings.APPID
    secret = settings.SECRET



    @classmethod
    def get_openid(cls,code):
        url = cls.url + "?app
        return requests.get(url).json()
