javascript - 返回 HttpResponse 并在 PayPal 系统中进行响应

Question

我是贝宝系统的新手，我在捕获从客户端服务器返回的 orderID 时遇到了很大的问题。

我在服务器端有这个代码：

[HttpPost]
[Route("/Order/create-paypal-order")]
public async Task<HttpResponse> CreatePayPalOrder(bool debug = false)
{
    var request = new OrdersCreateRequest();
    request.Prefer("return=representation");
    request.RequestBody(BuildRequestBody());
    //3. Call PayPal to set up a transaction
    HttpResponse response = await PayPalClient.client().Execute(request);
    if (debug)
    {
        var result = response.Result<Order>();
        Console.WriteLine("Status: {0}", result.Status);
        Console.WriteLine("Order Id: {0}", result.Id);
        Console.WriteLine("Intent: {0}", result.CheckoutPaymentIntent);
        Console.WriteLine("Links:");
        foreach (LinkDescription link in result.Links)
        {
            Console.WriteLine("\t{0}: {1}\tCall Type: {2}", link.Rel, link.Href, link.Method);
        }
        AmountWithBreakdown amount = result.PurchaseUnits[0].AmountWithBreakdown;
        Console.WriteLine("Total Amount: {0} {1}", amount.CurrencyCode, amount.Value);
    }

    return response;
}
private static OrderRequest BuildRequestBody()
{
    OrderRequest orderRequest = new OrderRequest()
    {
        CheckoutPaymentIntent = "CAPTURE",

        ApplicationContext = new ApplicationContext

                        {

              }
            }
    };

    return orderRequest;
}

在客户端：

<div id="paypal-button-container" style="text-align: center"></div>
<script>
    paypal.Buttons({
        createOrder: function () {
            return fetch('/Order/create-paypal-order', {
                method: 'post',
                headers: {
                    'content-type': 'application/json'
                }
            }).then(function (res) {
                console.log(res);
                var a = res.json();
                alert("RES:" + a);
                console.log(a);
                return a;
            }).then(function (data) {
                console.log(data);
                alert("DATA: " + data.id);
                return data.id; // Use the key sent by your server's response, ex. 'id' or 'token'
            });
        },
        onApprove: function (data, actions) {
            // This function captures the funds from the transaction.
            return actions.order.capture().then(function (details) {
                // This function shows a transaction success message to your buyer.
                alert('Transaction completed by ' + details.payer.name.given_name);
            });
        }
  }).render('#paypal-button-container');
</script>

这是我在调试时得到的：

如您所见，有数据和 ID 以及其他所有内容（不确定是否需要直接在“标题”中，但也尝试手动添加）

在客户端，我收到错误“预计要传递一个订单 ID”。这是控制台：

所有返回数据都需要位于服务器 HTTP 响应的正文（而不是标头）中，格式为 JSON。您应该能够将完整的 URL/Order/create-paypal-order放入任何 Web 浏览器并查看 JSON 数据，其中 id 键具有 orderID 值。如果您看不到这一点，则您的服务器正在返回错误的数据或格式错误。

您还应该在浏览器开发者工具的网络选项卡中调试服务器返回的内容，在获取请求的响应部分到/Order/create-paypal-order. 如果您确实返回了与您的服务器对象对应的 JSON 数据，这将被格式化为原始字符串，result就像您应该的那样。
