Question

我尝试将PayPal PLUS API集成到NativeScript Mobile App中。当创建付款（调用此API：https://developer.paypal.com/docs/api/payments/#create_payment）并且旁边显示缩短的调用时，我一直收到500错误。可悲的是，我没有找到如何显示它的消息。

我通过NativeScript在iOS模拟器（Xcode 7）上运行我的代码。

我尝试了以下curl-call，这对我有用：

我尝试使用curl：

<router-outlet></router-outlet>

回复201创建的回复。

现在我在TypeScript中使用相同的元素创建了一个XHR-Object。到目前为止我的代码：

curl -v -X POST https://api.sandbox.paypal.com/v1/payments/payment \
-H "Content-Type:application/json" \
-H "Authorization: Bearer <my-token>„ \
-d '{
  "intent": "sale",
  "payer": {
      "payment_method": "paypal"
  },
  "transactions": [
  {
      "amount": {
      "total": "30.11",
      "currency": "EUR",
      "details": {
          "subtotal": "30.00",
          "tax": "0.07",
          "shipping": "0.03",
          "handling_fee": "1.00",
          "shipping_discount": "-1.00",
          "insurance": "0.01"
      }
  },
  "item_list": {
      "items": [
      {
          "name": "hat",
          "description": "Brown hat.",
          "quantity": "5",
          "price": "3",
          "tax": "0.01",
          "sku": "1",
          "currency": "EUR"
      },
      {
          "name": "handbag",
          "description": "Black handbag.",
          "quantity": "1",
          "price": "15",
          "tax": "0.02",
          "sku": "product34",
          "currency": "EUR"
      }
    ]}
  }
  ],
  "redirect_urls": {
  "return_url": "http://www.paypal.com/return",
  "cancel_url": "http://www.paypal.com/cancel"
  }
}'

（如上所述）不适合我。有人知道，如何显示该XHR-Object的错误消息？或许有人甚至可以看到我的代码可能出现的问题。如果您需要一个有效的API调用（通过XHR）：

    var oReq = new XMLHttpRequest();    
    oReq.open("POST", PayPalEndpoints.getPaymentEndpoint, true);
    oReq.setRequestHeader('Authorization', "Bearer " + access_token);
    oReq.setRequestHeader('Accept', "application/json");
    oReq.onreadystatechange = function () {
        console.log("state changed - new state: " + oReq.readyState + " and Status: " + oReq.status);
        if (oReq.readyState === 4) {     
            if (oReq.status === 200) {        
                var response = JSON.parse(oReq.responseText);          
                console.log("response = " + response);
            } else { 
                console.log("Error: " + oReq.status + " Message: " + oReq.responseText);
            } 
        }    
    };

    oReq.send({
        "intent": "sale",
        "payer": {
            "payment_method": "paypal"
        },
        "transactions": [
        {
            "amount": {
                "total": "30.11",
                "currency": "EUR",
                "details": {
                "subtotal": "30.00",
                "tax": "0.07",
                "shipping": "0.03",
                "handling_fee": "1.00",
                "shipping_discount": "-1.00",
                "insurance": "0.01"
            }
            },
            "item_list": {
                "items": [
                    {
                        "name": "hat",
                        "description": "Brown hat.",
                        "quantity": "5",
                        "price": "3",
                        "tax": "0.01",
                        "sku": "1",
                        "currency": "EUR"
                    },
                    {
                        "name": "handbag",
                        "description": "Black handbag.",
                        "quantity": "1",
                        "price": "15",
                        "tax": "0.02",
                        "sku": "product34",
                        "currency": "EUR"
                    }
                ]
            }
        }
        ],
        "redirect_urls": {
            "return_url":"http://www.paypal.com/return",
            "cancel_url":"http://www.paypal.com/cancel"

如果有人正在研究同等问题：

您需要更改

 oReq.setRequestHeader('Accept', "application/json");

到

oReq.setRequestHeader('Grant-Type', "application/json");

并且您需要将send-Method中的数据作为json-string传递，因此请调用：

 oReq.send(JSON.stringify(data));

使用＆＃34;数据＆＃34;成为你的JSON字符串。

尝试创建付款对象时，PayPal REST API返回500错误
