微信小程序获取手机号码

一.小程序端

 

 

1.index.wxml

 

<button open-type="getPhoneNumber" bindgetphonenumber="getPhoneNumber">获取手机号</button>

<button bindtap="sessionkey">获取sessionkey</button>

 

2.index.js

 

//index.js

//获取应用实例

const app = getApp()

Page({

  data: {

    sessionkey:''

  },

  getPhoneNumber (e) {

     wx.request({

       url: 'http://localhost:8080/getPhone',

       data:{

        vi:e.detail.iv,

        sessionKey:this.data.sessionkey,

        enData:e.detail.encryptedData

       },

       method:"get",

       success:function(data){

        console.log(data.data)

       }

     })

  },

  sessionkey(){

    

    wx.login({

      complete: (res) => {

        var that=this;

        wx.request({

          url: 'http://localhost:8080/getCode',

          data:{code: res.code},

          method:'get',

          success(data){

           that.setData({

            sessionkey:data.data

           })

          }

        })

      }

    })

  }

})
