Post JSON 数据到 vb.net 中的网络服务器使用 JSON.Net

Question

我正在尝试将 post 数据以 JSON 形式发送到网站，但无论我做什么，我都会收到 500 内部错误。

我打算创建的字符串是这样的：{"orders":[{"id":"7","invoice_number":"1007"},{"id":"8","invoice_number":"1008"},{"id":"11","invoice_number":"1011"}]} ，我可以用 JSON.net

站点的网站管理员向我发送了此命令，以便 post 数据

curl -vvvvvvvv "http://staging.voltige2001.net/fr/api/update-orders" --data '{"orders":[{"id":"7","invoice_number":"1007"},{"id":"8","invoice_number":"1008"},{"id":"11","invoice_number":"1011"}]}' -X PATCH

但我不知道什么是 curl 以及这与我所做的有何不同。

这是我的代码：

    Dim strInvNumber As String

    If Not IsNothing(oDsFacture) AndAlso oDsFacture.Tables.Count > 0 AndAlso oDsFacture.Tables(0).Rows.Count > 0 Then
        strInvNumber = oDsFacture.Tables(0).Rows(0)("No_Facture")
    Else
        strInvNumber = "9999" ' Pas de facture
    End If

    Dim oOrder As New Confirmation.Order With {.ID = oCommande.ID, .InvoiceNumber = strInvNumber}

    Dim oConfirmation As New Confirmation With {.Orders = New List(Of Confirmation.Order) From {oOrder}}
    Dim strResponse As String = JsonConvert.SerializeObject(oConfirmation)

    Dim data = Encoding.UTF8.GetBytes(strResponse)


    Dim req As WebRequest = WebRequest.Create(_ResponseURL)
    req.ContentType = "application/json"
    req.Method = "POST"
    'req.ContentLength = strResponse.Length

    Using oStream As New StreamWriter(req.GetRequestStream)
        oStream.Write(strResponse)
        oStream.Flush()
        oStream.Close()
    End Using

    Try
        Dim response As HttpWebResponse = req.GetResponse
        Using oSReader As New StreamReader(response.GetResponseStream)

        End Using
    Catch ex As Exception

    End Try

这是我用来转换成JSON

的class

Public Class Confirmation


Public Class Order
    <JsonProperty("id")> Public Property ID As String
    <JsonProperty("invoice_number")> Public Property InvoiceNumber As String
        End Class

<JsonProperty("orders")> Public Property Orders As List(Of Order)
End Class

curl 是一个用于传输网络数据的命令行工具。这是手册页：man.cx/curl.

给定的 curl 示例中的 -X 选项表示使用 GET 以外的其他内容。在这种情况下，他们期待 PATCH。试试 req.Method = PATCH.

我之前没有运行进入 PATCH 方法，RFC 摘要让它听起来像一个 HTTP upsert：

The PATCH method requests that a set of changes described in the request entity be applied to the resource identified by the Request- URI. The set of changes is represented in a format called a "patch document" identified by a media type. If the Request-URI does not point to an existing resource, the server MAY create a new resource, depending on the patch document type (whether it can logically modify a null resource) and permissions, etc.
