WCF Rest和Soap服务-（415）无法处理消息，因为内容类型'；应用程序/json；字符集=utf-8'；

无法处理消息，因为内容类型为“application/json；charset=utf-8“不是预期的类型”text/xml；字符集=utf-8'

我有一个支持Soap的WCF服务，该服务按预期工作，但当我尝试将其作为Restful服务使用时，我收到了上面的错误消息。我花了无数个小时研究错误，尝试了所有建议，但都没有成功

这是我的Web.config`

有没有关于如何修复此错误的建议？

在我尝试之后，我认为问题可能在于服务接口的实现。您可以提供实现该服务的特定代码吗？公共函数GetRestTestData（sData）作为字符串实现ITest_Rest_服务。GetRestTestData Dim oOutput作为对象oOutput=New，带有{.Return=“Hello World”}返回新的JavaScriptSerializer（）.Serialize（oOutput）结束函数

<ServiceContract()>
Public Interface ITest_Service

<OperationContract()>
Function GetData(ByVal TestInfo As TestInputData) As TestOutputData

End Interface

    <ServiceContract()>
Public Interface ITest_Rest_Service
    <OperationContract()>
    <WebInvoke(Method:="Post", UriTemplate:="GetRestTestData", BodyStyle:=WebMessageBodyStyle.Bare, RequestFormat:=WebMessageFormat.Json, ResponseFormat:=WebMessageFormat.Json)>
    Function GetRestTestData(sData As String) As String
End Interface

Dim oData As Object = New With {
                        Key .Client = "123",
                        Key .DeviceType = "Computer"             
                      }

        sData = (New JavaScriptSerializer().Serialize(oData))
        Dim sURL As String = "https://Test.com/Test_Service.svc/GetRestTestData"
        Dim postReq As HttpWebRequest = DirectCast(WebRequest.Create(New Uri(sURL)), HttpWebRequest)
        postReq.Method = "Post"
        postReq.ContentType = "application/json; charset=utf-8"
        postReq.Accept = "application/json"            
        Dim byteData As Byte() = Encoding.UTF8.GetBytes(sData)
        postReq.ContentLength = byteData.Length

        Dim postreqstream As Stream = postReq.GetRequestStream()
        postreqstream.Write(byteData, 0, byteData.Length)
        postreqstream.Close()

        Dim postresponse As HttpWebResponse

        postresponse = DirectCast(postReq.GetResponse(), HttpWebResponse)
