WCF 休息服务 500 内部服务器错误

Question

I encountered followed exception while accessing service method.All GET methods working properly on my service but when i run a POST method as followed i am getting 500 Internal Server Error.

https://mservice.domain.com/ServicesRestful.svc/json/addorder

{"userId":"30155496","locationId":"10","order":"lorem"}

Service Code

[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "addorder", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
[FaultContract(typeof(ServiceException), Name = "ServiceException")]
Standard AddOrder(string personId, int locationId, string order);

Error message

The incoming message has an unexpected message format 'Raw'. The expected message formats for the operation are 'Xml'; 'Json'. This can be because a WebContentTypeMapper has not been configured on the binding. See the documentation of WebContentTypeMapper for more details.

Answer 1

Change your contract in this way:

[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "addorder", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)]
[FaultContract(typeof(ServiceException), Name = "ServiceException")]
Standard AddOrder(Order order);

Where your Order class is:

[DataContract]
public class Order
{
    [DataMember]
    public string personId {get; set;}
    [DataMember]
    public int locationId {get; set;}
    [DataMember]
    public string order {get; set;}
}

Now, try and run. Make sure that your JSON is in proper format.
