php - 沙盒 Paypal 结帐(PHP，Laravel)

Question

我正在尝试对我的 Laravel Api(连接到 Ionic 应用程序)实现 Paypal 结帐，当我在应用程序中按下结帐按钮并在登录时转到 Paypal(到目前为止一切正常)时，它会卡住屏幕。我发现它很奇怪，因为它不允许我使用我的沙盒帐户甚至我的真实帐户登录，错误是相同的:“您的某些信息不正确。请重试。”通过打开开发人员工具，这些是我得到的错误(见屏幕截图)。我真的找不到我在这里犯错的地方。也许你可以帮助我。下面是屏幕截图和使用 Paypal 结账的代码。让我知道我是否应该在此处添加任何额外信息!非常感谢!

错误 1: , 调查其中一个控制台错误:

Route::middleware('auth:api')->post('/paypal', function (Request $request) {
    $user = $request->user();
    $data = $request->all();
    $list_products_id = $data;

    $products = [];
    $total = 0;

    $titles = '';

    foreach($list_products_id as $key => $value) {
        $product = Product::find($value);
        if($product){
            $products[$key] = $product;
            $total += $product->price;
            $titles .= $product->title." ";
        } 
    }

    if($total){

        $paypal = config('app.paypal', "sandbox");

       if($paypal == "sandbox"){
            $userProvider = 'In my app I have the sandbox business credentials here';

       $data['L_PAYMENTREQUEST_0_QTY0'] = '1'; //number of the same product the user is ordering
       $data['L_PAYMENTREQUEST_0_AMT0'] = number_format($total, 2).'';

       $data['L_BILLINGAGREEMENTDESCRIPTION0'] = $titles;

       $data['CANCELURL'] = url('/');
       $data['RETURNURL'] = url('/');

      // curl

      $data = http_build_query($data);

      $curl = curl_init();
      curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

      curl_setopt($curl, CURLOPT_POST, true);

      $response =  curl_exec($curl);
      curl_close($curl);

      $nvp = array();

      if (preg_match_all('/(?<name>[^\=]+)\=(?<value>[^&]+)&?/', $response, $matches)) {
          foreach ($matches['name'] as $offset => $name) {
              $nvp[$name] = urldecode($matches['value'][$offset]);
          }
      }

      if(isset($nvp['ACK']) && $nvp['ACK'] == "Success" ){
        $query = array(
                'cmd'    => '_express-checkout',
                'token'  => $nvp['TOKEN']
            );

            $redirectURL = sprintf($url2, http_build_query($query));

            return ['date'=>$redirectURL];
      }else{
        return ['status'=>'error purchasing! - 1'];

      }

    }

    echo "total: " . $total;
    return ['status'=>'error purchasing! - 2'];
});
