How to get the mobile phone number in the mini program (thinkphp3.2.3 framework)

The content of this article is about how to obtain a mobile phone number through a small program (thinkphp3.2.3 framework). It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

1. Directly upload the code php

namespace Home\Controller;
use Think\Controller;
class ApiController extends Controller {
    /**
 * error code 说明.
 * <ul>

 *    <li>-41001: encodingAesKey 非法</li>
 *    <li>-41003: aes 解密失败</li>
 *    <li>-41004: 解密后得到的buffer非法</li>
 *    <li>-41005: base64加密失败</li>
 *    <li>-41016: base64解密失败</li>
 * </ul>

//2. Mini program

2.1 Log in first on the app.js startup page

// 登录
    // if (!wx.getStorageSync(&#39;session_key&#39;) || wx.getStorageSync(&#39;time&#39;) < Date.parse(new Date())){ // 判断session_key是不是存在获者过期
      wx.login({
        success: res => {
          console.log(res)
          // 发送 res.code 到后台换取 openId, sessionKey, unionId
          wx.request({
            url: &#39;https://www.zhixiaobing.com/index.php?m=&c=api&a=getopenId&#39;,
            header: { "Content-Type": "application/x-www-form-urlencoded" },
            method: &#39;post&#39;,
            data: { code: res.code },
            success: function (res) {
              console.log(res.data);
              wx.setStorageSync(&#39;openid&#39;, res.data.openid)
              wx.setStorageSync(&#39;session_key&#39;, res.data.session_key)
              wx.setStorageSync(&#39;time&#39;, parseInt(Date.parse(new Date())) + 7200)
            }
          })
          
        }
      })

//2.2 Write components in the mini program template

<button open-type="getPhoneNumber" bindgetphonenumber="getPhoneNumber" >//这是官方的组件点击会弹出授权页面

Write the following function in js

getPhoneNumber: function (e) {
    var that =this;

    var session_key = wx.getStorageSync('session_key')
    if (e.detail.errMsg == 'getPhoneNumber:fail user deny') {
      wx.showModal({
        title: '提示',
        showCancel: false,
        content: '未授权',
        success: function (res) { }
      })
    } else {//确认授权
      wx.request({
        url: 'https://www.showoow.com/index.php?m=mini&c=api&a=getPhoneNumber&openid=' + wx.getStorageSync('openid'), //openid是app.js 已经存的
        header: {"Content-Type": "application/x-www-form-urlencoded" },
        method: "get",
        data: {
          encryptedData: e.detail.encryptedData, iv: e.detail.iv, session_key:session_key
        },
        success:function(res){
          if (res.data.msg.phoneNumber){
            console.log(res);
            wx.showModal({
              title: '提示',
              showCancel: false,
              content: '授权成功',
              success: function () {
                wx.setStorageSync('phoneNumber', res.data.msg.phoneNumber);
                var time = Date.parse(new Date()) + 60 * 60 * 24 * 2
                wx.setStorageSync('exp', time );
              }
            })
            setTimeout(function(){
              wx.navigateTo({
                url: '/pages/form/form',
              })
            },1500);
            that.setData({
              show:'show',
              hiden:''
            })
          }else{
            wx.showToast({
              title: '授权失败',
              icon:'loading'
            })
          }
        
        },
        fail:function(){
          wx.showToast({
            title: '授权失败',
            icon: 'loading'
          })
        }
      })
     
    }
  },

This is the end of the mini program to obtain the mobile phone number. I wrote a mini program in the company. You can Get the mobile phone number normally
