Laravel +贝宝+ cUrl +离子

我希望您能帮助我解决在Laravel中与Paypal一起使用curl的问题。我正在将其与Ionic集成。当我按下购买按钮时,它中断了,该应用给出了以下错误:

  

无法获取/未定义。

我正在关注一个教程,其结果应该是,通过按下按钮进行购买,该应用会将用户重定向到Paypal。请注意,在按按钮出现错误后,控制台在开发人员工具上变为空白(可能是因为它试图将用户重定向到应用程序外部的贝宝?),因此我无法真正进一步调查错误,但是我提到的那些瞬间就可以看到,就是我提到的那些!

下面的代码与我正在遵循的教程完全相同,我知道它可能不会说太多,因为在其他地方可能有问题,但是确实如此。我将代码粘贴到Laravel api.php文件中,并且收到的错误向我显示了输出:“错误购买!-1”,这是我在Laravel的第二个“ else”块中打印的消息代码,这可能暗示了我无法捕获的问题。我还将粘贴该函数的功能称为api的ionic应用程序。

我知道我可能会提供有限的信息,所以请让我知道您还需要什么其他信息,甚至可以帮助我进一步调试这些信息!

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 = '';
            $pwdProvider = '';
            $signProvider = '';
            $url = 'https://api-3t.sandbox.paypal.com/nvp';
            $url2 = 'https://www.sandbox.paypal.com/cgi-bin/webscr?%s';

       } else {
            $userProvider = '';
            $pwdProvider = '';
            $signProvider = '';   
            $url = 'https://api-3t.paypal.com/nvp';
            $url2 = 'https://www.paypal.com/cgi-bin/webscr?%s';
       }

       $data = [];
       $data['USER'] = $userProvider;
       $data['PWD'] = $pwdProvider;
       $data['SIGNATURE'] = $signProvider;
       $data['METHOD'] = 'SetExpressCheckout';
       $data['VERSION'] = '108';
       $data['LOCALECODE'] = 'en_US';

       $data['L_PAYMENTREQUEST_0_NAME0'] = "Products Orders";
       $data['L_PAYMENTREQUEST_0_DESC0'] = $titles;

       $data['PAYMENTREQUEST_0_AMT'] = number_format($total, 2).'';

       $data['PAYMENTREQUEST_0_CURRENCYCODE'] = 'EUR';
       $data['PAYMENTREQUEST_0_PAYMENTACTION'] = 'Sale';

       $data['L_PAYMENTREQUEST_0_QTY0'] = '100'; //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($curl, CURLOPT_SSL_VERIFYPEER, false);
      curl_setopt($curl, CURLOPT_POST, true);
      curl_setopt($curl, CURLOPT_URL, $url);
      curl_setopt($curl, CURLOPT_POSTFIELDS, $data);

      $response =  curl_exec($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'];
});

下面是离子代码:

purchase() {
    console.log("Order");
    if (!this.user) {
      this.navCtrl.push(LoginPage);
      return;
    }
    this.cartProvider.purchase(this.cart, this.user).subscribe(
      res => {
        if (res) {
          console.log(res);
          // this.showToast("top", "Checkout completed successfully!");
          window.location.href = res.date;
          this.removeAll();
        }
      },
      error => {
        console.log("Error: " + error);
        this.showToast("top", "Error checking out");
      }
    );
  }

@BizzyBob感谢您的建议,最后我发现我为参数添加了错误的值:

$ data ['L_PAYMENTREQUEST_0_QTY0'] ='1';

以前我有:

$ data ['L_PAYMENTREQUEST_0_QTY0'] ='100';

将其更改为“ 1”解决了该问题。在我看来,很难找到解决方案,因为我们一直在其他地方寻找解决方案...因此,我想提醒一下外面的任何人,请务必仔细检查参数值,否则可能会引起错误,您可能会尝试这样做在不同的地方调试!
