Javascript PayPal Checkout v2 SDK.NET与PayPalHttp.HttpResponse存在问题

我在事务设置流程的最后一部分遇到问题： 客户端正确地调用我的后端，该后端调用PayPal创建订单，并收到状态代码为200的响应

当http响应返回到客户端时会发生错误，这里我们意识到paypal类创建的json是不完整的！没有使json无效的右括号。“}]}”

我向paypal团队寻求帮助，但它没有帮助我。他们继续绕过这个问题，说蜜蜂总是将完整的json返回给我，但我也知道这一点，因为在调试模式下，结果会给我一个链接，正确地将我发送回paypal支付

这让我明白，实际上我创建的流是完整的，但是PayPalHttp.HttpResponse类创建了一个不正确的主体

我正在附上密码

Public Shared Async Function CreateOrder(ByVal Optional debug As Boolean = False) As Task(Of PayPalHttp.HttpResponse)

    Dim result As New Order
    Dim request = New OrdersCreateRequest()

    request.Prefer("return=representation")
    Dim newRequest As New OrderActionRequest
    request.RequestBody(BuildRequestBody(dicNameValue))


    Dim response = Await PayPalClient.client().Execute(request)

    If debug Then
    result = response.Result(Of Order)()
    Console.WriteLine("Status: {0}", result.Status)
    Console.WriteLine("Order Id: {0}", result.Id)
    Console.WriteLine("Links:")

    For Each link As LinkDescription In result.Links
    Console.WriteLine(vbTab & "{0}: {1}" & vbTab & "Call Type: {2}", link.Rel, link.Href, link.Method)
    Next

     /*--- HERE THE PROBLEM ----*/
    Dim json As String = PayPalClient.ObjectToJSONString(result)
    Console.WriteLine("Response JSON: {0}", json)
    /*----------*/

    Dim amount As AmountWithBreakdown = result.PurchaseUnits(0).AmountWithBreakdown
    Console.WriteLine("Total Amount: {0} {1}", amount.CurrencyCode, amount.Value)

    End If

    Return response
  End Function

这是不完整的json：

注：该项目在VB.NET 4.6.1（web表单）中

Dim响应=等待PayPalClient.client（）.Execute（请求）

什么是

响应

您能否在

PayPalClient.client（）.Execute（request）

贝宝通过网络发送JSON。看起来您正在接收JSON，它被转换成一个对象，然后您正在调用该对象上的一个函数来返回JSON

---

我不知道为什么在您调用该函数时，该函数给出了错误的JSON，但我知道PayPal的原始JSON可能已经完成。

响应是一个

PayPalHttp.HttpResponse

，这些都是PayPal dll提供的类。PayPalClient.ObjectToJSONString（结果）方法仅用于检查这些类正在执行的操作。Paypal似乎不想让我相信他们的.NET类有问题。他们的.NET类可能有问题，但作为JSON接收的数据应该没有问题，类内的数据可能也没有问题。当你把这个类从一个对象转换回JSON时，你在进程中投入了太多的麻烦，所以我的建议是，回溯一点。将类的内容作为数据结构检查（不将其转换为JSON），更好的是检查HTTP请求中通过网络从PayPal接收的JSON。这一切都应该是有效和完整的。技术支持部门向我展示了他们发送的json是完整的，然后说要在stackoverflow上查找答案，因为他们无法帮助我，最后他们链接了我这个：。在几行文字中你比在5-6封电子邮件中的Paypal更了解你。
