php后台代码

public function wxlogin(Request $request){
        $code['code']=$request['code'];
        $url =sprintf(config('wx.code'),$code['code']);
        //  $url = sprintf($url, $appid, $appkey, $code);
        $info= json_decode(file_get_contents($url),true);

        unset($code['session_key']);
        $code['openid']=$code['code'];

        $token= md5(md5($code['openid']),time()).rand(1,1000);
//        print_r($code['openid']);die();
        Cache::set($token,7200);
//        Renting::create($code['openid']);

//        Renting::create($token);

        dd($token);
    }
