php - 如何将“g-recaptcha-response”分配给变量？'g-recaptcha-response' 是 $request->validate([]) 中的一个参数

Question

所以我想要的是将'g-recaptcha-response'放在一个变量中，以便能够在我的条件下使用它来验证recaptcha，但我无法做到这一点。有没有办法只使用 validate() 中的数组中的 recaptcha 字段，因为我的代码原样将我重定向回主页。它直接进入 else 语句。

 public function contactanospost(Request $request){     
         $request->validate([                       
           'nombre' => 'required|distinct',
           'telefono'=> 'required|telefono',
            'correo' => 'required|email',
           'mensaje' => 'required',
        'g-recaptcha-response' => 'required|captcha',

         ]);
         if(POST['g-recaptcha-response']){             /*here I am trying to 
                                                   check with a condition if recaptch was really validated once the form is submitted */
           $token= POST['g-recaptcha-response'];
          $client = new Client();
          $response = $client->post('https://www.google.com/recaptcha/api/siteverify', [

          'form_params' => array('secret' => 'mycaptchakey',
          'response'=> $token                       /*Checking with google parameters for recaptcha if the user was indeed verified */
        )
      ]);                                     
      $resultados = json_decode($response->getBody()->getContents()); //decode with json
      if($resultados->success){ /*if this was a success then return a page with parameters from google recaptcha such as: secret, response, remote ip.*/
        dd($resultados); /*show the results from verified user and that recaptcha is working*/

   $contactanos = Contactanos::create($request->all());/* and create all fields for model Contactanos*/
   Mail::to('some@mail')->send(new enviacorreo($contactanos)); /* since it is a contact form then send all the information to some mail*/

     \Session::flash('flash_message','Tu mensaje ha sido enviado!'); /* send a message with "email delivered" verification*/
      return redirect()->back();
      }
      else{
        \Session::flash('flash_message','Robot');
        return redirect('/');
      }


         }
         else{
           return redirect('/');
         }









 }

我现在可以使用 input() 访问请求属性，让我感到困惑的是我的 if 语句。真正的问题在于：

$resultados = json_decode($response->getBody()->getContents());

下一个 if 语句没有获得预期的成功，而是直接进入 else 并带有机器人消息：

 else{
    \Session::flash('flash_message','Robot');
    return redirect('/');
  }

您可以$request通过调用从对象访问请求的所有属性，例如，如果您已阅读文档，$request->input('g-recaptcha-response')这是访问请求的基础。

我可以借给您一个片段来执行此操作，也许它会帮助您重新考虑如何验证验证码：

use GuzzleHttp\Client;
....


    $v = Validator::make($request->all(), [
        'name' => 'required|min:2',
        'email' => 'required|email|max:255',
        'subject' => 'sometimes|required|min:3',
        'message' => 'required|min:3',
        'g-recaptcha-response' => 'sometimes|required'
    ], [
        'g-recaptcha-response.*' => 'Please verify that you are not a robot'
    ]);

    if ($v->fails()) {
        return [
            'success' => 'no',
            'data' => $v->errors()->first()
        ];
    }

    if ($request->get('g-recaptcha-response')) {
        $verify_form = [
            'secret'    => env('GOOGLE_RECAPTCHA_SECRET', 'default'), //better to save in config though
            'response'  => $request->get('g-recaptcha-response')
        ];

        $client = new Client();
        $verify_serial = '?'.http_build_query($verify_form);

        $response = $client->post('https://www.google.com/recaptcha/api/siteverify'.$verify_serial);
        $arrayed_response = json_decode($response->getBody()->getContents(), true);
        if(!$arrayed_response['success']){
            Log::notice('There is something wrong with the verification of recaptcha: ',$arrayed_response );
            return [
                'success' => 'no',
                'data' => 'Something went wrong in verification process',
            ];
        }
    }

这个想法是，您构建秘密和响应主体，并使用它向 Google 请求验证检查，就像您所做的一样，但将查询构建为直接到 url 的查询参数。

PS：您不必返回片段:)
