我最近将PayPal付款添加到了我的网站（一般使用Laravel）。因此，我使用this plugin。
我使用的完整代码是：
public function getCheckout(Request $request)
{
$userInfo = \App\User::where('id', '=', \Auth::user()->id)
->first();
if ($userInfo->street == "") {
$request->session()->flash('alert-info', 'Vor der ersten Bestellung müssen Sie erst Ihre Daten vervollständigen');
return redirect('/editData');
}
$cart = Cart::where('user_id', \Auth::user()->id)->first();
$items = $cart->cartItems;
$total = 0;
foreach ($items as $item) {
$total += $item->product->price;
}
$itemList = PayPal::itemList();
foreach ($items as $item) {
$product = Product::where('id', '=', $item->product->id)->first();
$itemName = $product->name;
$itemPrice = $product->price;
$payPalItem = PayPal::item();
$payPalItem->setName($itemName)
->setDescription($itemName)
->setCurrency('EUR')
->setQuantity(1)
->setPrice($itemPrice);
$itemList->addItem($payPalItem);
}
$payer = PayPal::Payer();
$payer->setPaymentMethod('paypal');
$details = PayPal::details();
$details->setShipping("2.50")
->setSubtotal($total);
$amount = PayPal:: Amount();
$amount->setCurrency('EUR');
$amount->setTotal(($total + 2.5));
$amount->setDetails($details);
$transaction = PayPal::Transaction();
$transaction->setAmount($amount);
$transaction->setItemList($itemList);
$transaction->setDescription('Ihr Warenkorb');
$redirectUrls = PayPal:: RedirectUrls();
$redirectUrls->setReturnUrl(action('PayPalController@getDone'));
$redirectUrls->setCancelUrl(action('PayPalController@getCancel'));
$payment = PayPal::Payment();
$payment->setIntent('sale');
$payment->setPayer($payer);
$payment->setRedirectUrls($redirectUrls);
$payment->setTransactions(array($transaction));
try {
$response = $payment->create($this->_apiContext);
} catch (PayPalConnectionException $ex) {
echo $ex->getCode(); // Prints the Error Code
echo $ex->getData(); // Prints the detailed error message
die($ex);
}
$redirectUrl = $response->links[1]->href;
return Redirect::to($redirectUrl);
}
public function getDone(Request $request)
{
$cart = Cart::where('user_id', \Auth::user()->id)->first();
$items = $cart->cartItems;
$total = 0;
foreach ($items as $item) {
$total += $item->product->price;
}
$order = new Order();
$order->total_paid = $total + 2.5;
$order->user_id = \Auth::user()->id;
$order->save();
foreach ($items as $item) {
$orderItem = new OrderItem();
$orderItem->order_id = $order->id;
$orderItem->product_id = $item->product->id;
$orderItem->save();
$product = $item->product;
if ($product->stockCount != "") {
$product->stockCount--;
}
$product->save();
CartItem::destroy($item->id);
}
$id = $request->get('paymentId');
$token = $request->get('token');
$payer_id = $request->get('PayerID');
$payment = PayPal::getById($id, $this->_apiContext);
$paymentExecution = PayPal::PaymentExecution();
$paymentExecution->setPayerId($payer_id);
try {
$payment->create($this->_apiContext);
} catch (PayPalConnectionException $ex) {
echo $ex->getCode(); // Prints the Error Code
echo $ex->getData(); // Prints the detailed error message
die($ex);
}
try {
$payment->execute($paymentExecution, $this->_apiContext);
} catch (PayPalConnectionException $ex) {
echo $ex->getCode();
echo $ex->getData();
die($ex);
}
// Clear the shopping cart, write to database, send notifications, etc.
// Thank the user for the purchase
$userInfo = \App\User::where('id', '=', \Auth::user()->id)
->first();
$userMail = $userInfo->email;
$orderItems = OrderItem::where('order_id', '=', $order->id)->get();
Mail::to($userMail)->send(new orderFinished($order));
$sellerArray = [];
foreach ($orderItems as $orderItem) {
$product = $orderItem->product;
$seller = User::where('id', '=', $product->user_id)->first();
$buyer = User::where('id', '=', $order->user_id)->first();
if (!in_array($seller, $sellerArray)) {
Mail::to($seller->email)->send(new newOrderMail($order, $seller, $buyer));
array_push($sellerArray, $seller);
}
}
return view('checkout.done');
}
以前工作过，我很确定我没有改变任何东西，但突然间它不再起作用了...... 我收到此错误：
400 {＆＃34; name＆＃34;：＆＃34; MALFORMED_REQUEST＆＃34;，＆＃34; message＆＃34;：＆＃34;传入的JSON请求未映射到API请求＆＃34;，＆ ＃34; information_link＆＃34;：＆＃34; https://developer.paypal.com/webapps/developer/docs/api/#MALFORMED_REQUEST＆＃34;，＆＃34; debug_id＆＃34;：＆＃34; 5c8663496f505＆＃34;} PayPal \ Exception \ PayPalConnectionException：获得Http响应代码访问https://api.sandbox.paypal.com/v1/payments/payment
时为400有人发现为什么会发生这种情况会有问题吗？我真的不知道......
编辑：在恢复到最新版本后（我确信它有效），我收到另一个错误，说：
PayPalConnectionException in PayPalHttpConnection.php line 174:
Got Http response code 500 when accessing https://api.sandbox.paypal.com/v1/payments/payment/PAY-1DS60820MW1392725LAYAB6A/execute.

at Controller->callAction('getDone', array(object(Request))) in ControllerDispatcher.php line 44
at ControllerDispatcher->dispatch(object(Route), object(PayPalController), 'getDone') in Route.php line 189
但是：这并不是每次都会发生，有些订单有效，有些则没有，或者用其他话说：有时候它有效，有时候不行......我不知道的是，不仅仅是，为什么发生错误，但也发生了行为改变的原因，因为正如我所说，我所做的唯一一件事就是将文件恢复到最新版本（使用GIT）。从我的本地版本到最新版本的唯一变化是一些格式化的东西（(之前的空格等）以及stockCount，它只是产品的计数器，我也添加了一些尝试捕获执行（正如你在代码中看到的）
答案 0 :(得分：0)
嗨亲爱的抱歉细节。我认为发送给paypal的总金额没有正确计算。 当你在细节中设置小计时，你可以确认那里的小计集是用这个公式计算的 小计=总和（（item1价格*数量）+ ...（item2价格*数量）） 然后检查使用此公式计算的总金额 总计=小计+运费 只需确保发送到paypal的金额已正确计算
