- 当前 Bug 的表现（可附上截图）

- 预期表现

可以将openid单独获取出来

- 复现路径

- 提供一个最简复现 Demo

//app.js

App({

  onLaunch: function() {

    //获取access_token

    wx.request({

      url: 'http://api.wss.onlyjune.com/accessToken?client_id=20882088&secret=nGk5R2wrnZqQ02bed29rjzax1QWRIu1O',

      data: {},

      method: 'post',

      header: {

        'Content-Type': 'application/json'

      },

      success: function(res) {

        wx.login({

          success: function(a) {

            // console.log(a.code)

            //发送请求

            wx.request({

              url: 'http://api.wss.onlyjune.com/login/getWxOpenid.html',

              data: {

                access_token: res.data.access_token,

                wx_code: a.code

              },

              header: {

                'content-type': 'application/json'

              },

              success: function(b) {

                console.log(b.data)

                console.log("获取到的openid为：" + b.data.openid)

              }

            })

          }

        })

        //本地缓存access_token

        wx.setStorage({

          key: 'access_token',

          data: {

            access_token: res.data.access_token,

            expires: Date.parse(new Date()) + res.data.expires,

          },

          success: function() {},

        })

      },

      fail: function() {}

    })

  },

  globalData: {

    userInfo: null

  }

})
