Question

我正在寻找具有超过64K的SOAP请求的WCF错误400错误请求的解决方案。我知道当我谷歌时，有很多解决方案。但是，我仍然没有成功修复我的网站工作。因此，我在这里寻求专业建议。

客户端代码：

Private Sub Calculate()
    Dim svc As New XXXService.XXXServiceClient
    Dim i As Integer
    Dim attributes As List(Of XXXService.AttributesStruct)
    Dim calculateSingleResponse As XXXService.SingleXXXResponseStruct

    Try
        attributes = New List(Of XXXService.AttributesStruct)
        attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_One", .AttributesValue = "1"})
        attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Two", .AttributesValue = "XXX"})
        attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Three", .AttributesValue = "1"})
        attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Four", .AttributesValue = "0"})
        attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Five", .AttributesValue = "1"})
        attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Six", .AttributesValue = "70"})
        attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Seven", .AttributesValue = "80"})
        attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Eight", .AttributesValue = "09.12.2012"})
        attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Nine", .AttributesValue = "12.12.2012"})
        attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Ten", .AttributesValue = "15.11.2012"})
        i = 0
        While i < 80
            attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Eleven[" & i.ToString & "]", .AttributesValue = "2"})
            attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Twelve[" & i.ToString & "]", .AttributesValue = "5"})
            attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Thirteen[" & i.ToString & "]", .AttributesValue = "1"})
            attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Fourteen[" & i.ToString & "]", .AttributesValue = "NA"})
            attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Fifteen[" & i.ToString & "]", .AttributesValue = "0"})
            attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Sixteen[" & i.ToString & "]", .AttributesValue = "0"})
            i = i + 1
        End While
        attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Seventeen", .AttributesValue = "0"})
        attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Eighteen", .AttributesValue = "0"})
        attributes.Add(New XXXService.AttributesStruct With {.AttributesKey = "A_Nineteen", .AttributesValue = "0"})
        calculateSingleResponse = _
            svc.Calculate("Test", True, "XXX", attributes.ToArray(),{"P_XXX"})                  
        svc.Close()
        Response.Write("********************************************<br/>")
        Response.Write("[ErrorCode: " & calculateSingleResponse.ErrorCode & "]<br/>")
        Response.Write("[ErrorDescription: " & calculateSingleResponse.ErrorDescription & "]<br/>")

    Catch ex As Exception
        Response.Write("EXCEPTION:" & "<br/>" & ex.Message & "<br/>" & ex.StackTrace & "<br/>")
        If Not ex.InnerException Is Nothing Then
            Response.Write("INNER EXCEPTION:" & "<br/>" & ex.InnerException.Message & "<br/>" & ex.InnerException.StackTrace)
        End If
    End Try

End Sub

Answer 1

我自己发现了这个问题：

服务器端和客户端之间的绑定必须相同，因此我将两者都更改为basicHttpBinding
服务名称区分大小写，我将“WcfClient.XXXService”更改为“wcfClient.XXXService”，现在可以使用了。

希望这可以帮助其他人遇到同样的困难=）
