        //echo $url;
        $data=[];
        $data['unionid']=$unionid;
        $result=curl_call($url,'post',$data);
        $result=json_decode($result,true);
        if($result['No']=='0')
        {
            $this->BackResult('6', '您必须先在日拱一卒小程序成为会员');

服务器2

  //获取用户信息
    public function  getinfo()
    {
        // echo '<pre>';
        // print_r($_POST);
        // exit;
        $unionid=$_POST['unionid']?$_POST['unionid']:'';
        $back=[];
        if($unionid)
        {
            $info=DB::name('member')->field('member_id,openid,member_true_name')->where(['unionid'=>$unionid])->find();
            if(empty($info['member_id'])){
                $back['No']=0;
            }else{
                $totaljuanintegral=DB::name('juanintegral')->where(['openid'=>$info['openid']])->sum('giveintegarl');
                $back['No']=1;
                $back['membername']=$info['member_true_name'];
                $back['totaljuanintegral']=$totaljuanintegral;
            }
        }
         $res=json_encode($back,JSON_FORCE_OBJECT);
         //file_put_contents('./getinfo.txt',$res);
         return  $res;
    }

问题：curl获取到的结果有tp6返回的debug调试错误信息，不能json_decode,
解决办法：
在服务器2的环境配置文件中（.env）将APP_DEBUG设置为false,但是还想看到错误信息，需要在config/app.php中将show_error_msg设置为true，这样就hi则返回json数据了。
