WCF RESTful Service - HTTP POST Request - wcf

Question

I developed a WCF Service with the following post method:
[OperationContract]
[WebInvoke(Method = "POST",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Wrapped,
UriTemplate = "/InsertBearingData")]
bool InsertBearingData(String JSONString);
I am using Fiddler to formulate an HTTP POST Request for this method but, it is returning Status Code - 400 Bad Request. This is the request formulated:
Request Header:
Host: localhost:21468
Content-Length: 96
Content-Type: application/json
Request Body:
[{"start time":"29-03-2013 11:20:11.340","direction":"SW","end time":"29-03-2013 11:20:14.770"}]
Can you please tell me how to formulate a good request in order to get a succesful response?

Answer 1

There are a few issues in your code:
The data type of the parameter is string, but you're passing a JSON array to it; a string parameter requires a JSON string to be passed.
The body style of the operation is set to Wrapped, which means that the parameter should be wrapped in an object whose key is the parameter name, something like {"JSONString":<the actual parameter value>}
To receive a request like the one you're sending, you need to have an operation like the following:
[ServiceContract]
public interface ITest
{
[WebInvoke(Method = "POST",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Bare,
UriTemplate = "/InsertBearingData")]
bool InsertBearingData(MyType[] param);
}
[DataContract]
public class MyType
{
[DataMember(Name = "start time")]
public string StartTime { get; set; }
[DataMember(Name = "end time")]
public string EndTime { get; set; }
[DataMember(Name = "direction")]
public string Direction { get; set; }
}
