微信小程序获取用户绑定手机号码完整版_微信测试号可以获取手机号码吗

一、准备阶段

创建小程序项目（测试号即可）
创建Java后台项目（此处为SpringBoot 普通项目）
二、前端代码

WXML 代码

获取头像昵称

<block wx:else>
  <image bindtap="bindViewTap" class="userinfo-avatar" src="{{userInfo.avatarUrl}}" mode="cover"></image>
  <text class="userinfo-nickname">{{userInfo.nickName}}</text>
</block>

{{phone}} 获取手机号码 {{motto}}

JS 代码
//index.js
//获取应用实例
const app = getApp()

Page({
data: {
motto: ‘Hello World’,
userInfo: {},
hasUserInfo: false,
canIUse: wx.canIUse(‘button.open-type.getUserInfo’),
phone:""
},
//事件处理函数
bindViewTap: function() {
wx.navigateTo({
url: ‘…/logs/logs’
})
},
onLoad: function() {
var phone = wx.getStorageSync(‘phone’);
if (app.globalData.userInfo) {
this.setData({
userInfo: app.globalData.userInfo,
hasUserInfo: true
})
} else if (this.data.canIUse) {
// 由于 getUserInfo 是网络请求，可能会在 Page.onLoad 之后才返回
// 所以此处加入 callback 以防止这种情况
app.userInfoReadyCallback = res => {
this.setData({
userInfo: res.userInfo,
hasUserInfo: true
})
}
} else {
// 在没有 open-type=getUserInfo 版本的兼容处理
wx.getUserInfo({
success: res => {
app.globalData.userInfo = res.userInfo
this.setData({
userInfo: res.userInfo,
hasUserInfo: true
})
}
})
}
this.setData({
phone: phone
});
},
getUserInfo: function(e) {
console.log(e)
app.globalData.userInfo = e.detail.userInfo
this.setData({
userInfo: e.detail.userInfo,
hasUserInfo: true
})
},
getPhoneNumber: function (e) {
console.log(e.detail.iv);
console.log(e.detail.encryptedData);
wx.login({
success: res => {
console.log(res.code);
wx.request({
url: ‘http://192.168.1.28:8070/oauth’,
data: {
‘encryptedData’: e.detail.encryptedData,
‘iv’: e.detail.iv,
‘codes’: res.code
},
method: ‘GET’, // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT
header: {
‘content-type’: ‘application/json’
}, // 设置请求的 header
success: function (res) {
wx.setStorageSync(‘phone’, res.data.phoneNumber);
wx.showToast({
title: “号码为：”+res.data.phoneNumber,
icon: ‘none’
})
},
fail: function (err) {
console.log(err);
}
})
}
})
}
})
