php:

<?php
 
namespace App\Http\Controllers;
 
use App\Models\Login;
use App\Service\phone\WXBizDataCrypt;
use Illuminate\Http\Request;
 
class PhoneController extends Controller
{
    /**
     * 授权手机号
     */
    public function getPhone(request $request)
    {
         $appid = config('openid.openid');
         $sessionKey = $request->post('session_key');
         $iv = $request->post('iv');
        $encryptedData = $request->post('encryptedData');
         $openid = $request->post('openid');
 
        $pc = new WXBizDataCrypt($appid, $sessionKey);
        $errCode = $pc->decryptData($encryptedData, $iv, $data );
 
        if ($errCode == 0) {
            print($data . "\n");
        } else {
            print($errCode . "\n");
        }
        $newData = json_decode($data,true);
 
        if ($errCode==0){
           $res = Login::where('openid',$openid)->update(['phone'=>$newData['phoneNumber']]);
           if ($res!==false){
               return ['code'=>200,'msg'=>'手机号成功','data'=>$newData['phoneNumber']];
           }
        }
    }
}

首先封装一个服务层 

引入三个php文件

demo.php
<?php

}
