將PayPal Rest API SDK集成到laravel 5.2

Question

我在laravel 5.2中首次集成了paypal。我正在使用PayPal SDK作爲api，但我已經達到了被卡住的地步。當我提交付款表格時，我收到以下錯誤。

「PayPalHttpConnection.php中的PayPalConnectionException行176： 訪問https://api.sandbox.paypal.com/v1/payments/payment時得到Http響應代碼400」。

我從this website得到了教程，這裏是從我的控制器

​​

的代碼，我覺得redireciting PayPal網站出現問題的時候來到，但我無法弄清楚究竟是怎麼了。

Answer 1

我也遇到了這個問題 - 在我的情況下，我實際上發送了虛假的數據給貝寶。

在第一步嘗試捕獲異常，並獲得actualy errormessage的

// For testing purpose use the general exception (failed to catch with paypal for me) 
catch (Exception $ex) { 
    if (\Config::get('app.debug')) { 
    echo "Exception: " . $ex->getMessage() . PHP_EOL; 
    $err_data = json_decode($ex->getData(), true); 
    exit; 
    } else { 
    die('Some error occur, sorry for inconvenient'); 
    } 
} 

得到的消息應該給你足夠的信息來解決你得到了什麼錯。

下面我粘貼你我的代碼，這是我使用paypal REST api工作。您將需要3路

• /支付/創建（創建付款）
• /支付/成功（確認付款成功&來自PayPal重定向）
• /支付/取消（貝寶的手柄取消）

您還需要添加您的paypal配置並將其初始化到您的控制器中。如果您還沒有PayPal配置文件，您可以直接在該功能中設置客戶端ID和密碼。這些設置應該是這樣的

'settings' => array(
    /** 
    * Available option 'sandbox' or 'live' 
    */ 
    'mode' => 'sandbox', 

    /** 
    * Specify the max request time in seconds 
    */ 
    'http.ConnectionTimeOut' => 30, 

    /** 
    * Whether want to log to a file 
    */ 
    'log.LogEnabled' => true, 

    /** 
    * Specify the file that want to write on 
    */ 
    'log.FileName' => storage_path() . '/logs/paypal.log', 

    /** 
    * Available option 'FINE', 'INFO', 'WARN' or 'ERROR' 
    * 
    * Logging is most verbose in the 'FINE' level and decreases as you 
    * proceed towards ERROR 
    */ 
    'log.LogLevel' => 'FINE' 
) 

控制器

$paypal_conf = config('paypal'); 
    $this->_api_context = new ApiContext(new OAuthTokenCredential($paypal_conf['client_id'], $paypal_conf['secret'])); 
    $this->_api_context->setConfig($paypal_conf['settings']); 

的構造函數創建路線

// create a payment 
    public function create(Request $request) 
    { 
     $payer = new Payer(); 
     $payer->setPaymentMethod('paypal'); 

     $price = '10.00'; // 10 € for example 

     if($price == 0) { // ensure a price above 0 
      return Redirect::to('/'); 
     } 

     // Set Item 
     $item_1 = new Item(); 
     $item_1->setName('My Item') 
      ->setCurrency('EUR') 
      ->setQuantity(1) 
      ->setPrice($price); 

     // add item to list 
     $item_list = new ItemList(); 
     $item_list->setItems(array($item_1)); 

     $amount = new Amount(); 
     $amount->setCurrency('EUR') 
      ->setTotal($price); // price of all items together 

     $transaction = new Transaction(); 
     $transaction->setAmount($amount) 
      ->setItemList($item_list) 
      ->setDescription('Fitondo Fitnessplan'); 

     $redirect_urls = new RedirectUrls(); 
     $redirect_urls->setReturnUrl(URL::to('/payment/status')) 
      ->setCancelUrl(URL::to('/payments/cancel')); 

     $payment = new Payment(); 
     $payment->setIntent('Sale') 
      ->setPayer($payer) 
      ->setRedirectUrls($redirect_urls) 
      ->setTransactions(array($transaction)); 

     try { 
      $payment->create($this->_api_context); 
     } catch (\PayPal\Exception\PayPalConnectionException $ex) { 
      if (config('app.debug')) { 
       echo "Exception: " . $ex->getMessage() . PHP_EOL; 
       $err_data = json_decode($ex->getData(), true); 
       exit; 
      } else { 
       die('Error.'); 
      } 
     } 

     foreach($payment->getLinks() as $link) { 
      if($link->getRel() == 'approval_url') { 
       $redirect_url = $link->getHref(); 
       break; 
      } 
     } 

     /* here you could already add a database entry that a person started buying stuff (not finished of course) */ 

     if(isset($redirect_url)) { 
      // redirect to paypal 
      return Redirect::away($redirect_url); 
     } 

     die('Error.'); 
    } 

成功路線

public function get(Request $request) 
{ 
    // Get the payment ID before session clear 
    $payment_id = $request->paymentId; 

    if (empty($request->PayerID) || empty($request->token)) { 
     die('error'); 
    } 

    $payment = Payment::get($payment_id, $this->_api_context); 

    // PaymentExecution object includes information necessary 
    // to execute a PayPal account payment. 
    // The payer_id is added to the request query parameters 
    // when the user is redirected from paypal back to your site 
    $execution = new PaymentExecution(); 
    $execution->setPayerId($request->PayerID); 

    //Execute the payment 
    $result = $payment->execute($execution, $this->_api_context); 

    if ($result->getState() == 'approved') { // payment made 

     /* here you should update your db that the payment was succesful */ 

     return Redirect::to('/this-is-what-you-bought') 
      ->with(['success' => 'Payment success']); 
    } 

    return Redirect::to('/') 
     ->with(['error' => 'Payment failed']); 
} 

我希望我得到的一切 - 我不得不清理我的編碼以簡化它。
