小程序獲取用戶手機號

思路，書寫用戶授權登錄，登錄后獲取用戶頭像及用戶昵稱,通過wx.getUserProfile獲取用戶信息，再通過wx.login獲取code 用戶id和session_key傳后台進行添加入庫，跳轉至獲取手機號頁面.

login.wxml:

<button type="primary"  open-type="getUserInfo" bind:tap="login">授權登錄</button>

login:wxjs

 // 授權
     login(e){
      wx.getUserProfile({
      desc: 'desc',
      success:(res)=>{
      // 用戶昵稱
      let nickname=res.userInfo.nickName;
      // 用戶頭像
      let avatarUrl=res.userInfo.avatarUrl;
       if(res){
        wx.login({
      success:ret=>{
        // 獲取調用接口獲取登錄憑證（code）
     let code=ret.code;
      wx.request({
      url: 'http://www.day.com/day1/user/getUserInfo',
      method:'POST',
      data:{
        code:code,
        nickname:nickname,
        avatarUrl:avatarUrl
      },
      success:e=>{
        console.log(e);
        // 儲存用戶id
        wx.setStorageSync('id', e.data.data.id)
        wx.setStorageSync('session_key', e.data.data.session_key)
        if(e){
          //跳轉至獲取手機號頁面
         wx.switchTab({
           url: '/pages/my/my',
         })
       }
      }
    })



    }
  })

        }
        }
      })
      }





    

 

 

結合發送的網址，控制器代碼：

//    獲取用戶信息
    public function getUserInfo()
    {
        $params = \request()->post();
        $appid = "wx64832aa6eaea82b0";
        // 從微信公眾平台獲得secret
        $secret = "95e2acaf355dbcb443f5cd4748a152ed";
        // 發送請求換取openid和sessionkey
        // $url = "https://api.weixin.qq.com/sns/jscode2session?appid=$appid&secret=$secret&js_code=".$params['code']."&grant_type=authorization_code";
        $url = "https://api.weixin.qq.com/sns/jscode2session?appid={$appid}&secret={$secret}&js_code=" . $params['code'] . "&grant_type=authorization_code";;
        // 暫使用file_get_contents()發送請求，你可以使用CURL擴展的形式實現
        $result = json_decode(file_get_contents($url), true);
        $params['openid'] = $result['openid'];
        $params['session_key'] = $result['session_key'];
        //入庫
        $res = XcxUser::addUser($params);
        return json(['code' => 200, 'data' => $params, 'message' => 'ok']);
    }

模型代碼：

<?php
namespace app\common\model;

use think\Model;

class XcxUser extends Model
{
    //連接表名
    protected $table='xcx_user';
//    經用戶添加信息
    public static function addUser($params){
        return self::create($params,true);
    }
}

以上代碼書寫完成后，會進入/pages/my/my頁面

my.wxml:

 <button open-type="getPhoneNumber" bindgetphonenumber="getPhoneNumber">獲取手機號</button>

 

 

 my.wxjs:

getPhoneNumber (e) {
  // console.log(e.detail.iv)
  // console.log(e.detail.encryptedData)
  // 取出用戶id
  let uid=wx.getStorageSync('id');
  // 取出用戶session_key
  let session_key=wx.getStorageSync('session_key');
  //取出用戶iv
  let iv = e.detail.iv;
  //取出用戶encryptedData
  let encryptedData = e.detail.encryptedData;
  // 發送請求
  wx.request({
       url: 'http://www.day.com/day1/user/getPhoneNumber',
       method:'POST',
       data:{
         iv:iv,
         encryptedData:encryptedData,
         uid:uid,
         session_key:session_key
       },
       success:res=>{
         console.log(res);
       }
     })
}

 結合以上網址，進行控制器代碼：

<?php
namespace app\day1\controller;


use app\common\model\XcxUser;
use app\day1\model\SearchModel;
use app\day1\model\UserModel;
use think\Controller;
use think\Db;
use think\Request;
use app\services\phone\WXBizDataCrypt;

class User extends Controller
{

 public function getPhoneNumber()
    {
//        接受參數
        $encryptedData = input('encryptedData');
        $iv = input('iv');
        $sessionKey = input('session_key');
        $uid = input('uid');
        // 從微信公眾平台獲得$appid
        $appid = "wx64832aa6eaea82b0";
        $pc = new WXBizDataCrypt($appid, $sessionKey);
        $errCode = $pc->decryptData($encryptedData, $iv, $data);
        if ($errCode == 0) {
            return json(['code' => 200, 'data' => $data, 'message' => 'ok']);
        } else {
            return json(['code' => 500, 'message' => $errCode]);
        }
        
    }
}

效果圖：
