Question

I have a WCF service which is connected to an sql server database which is called from a mobile application. I have the following method which helps create bookings.

public void CreateBooking(Booking booking)
    {
        Booking newbooking = new Booking();
        sql = new SqlConnection("Data Source=comp;Initial Catalog=BookingDB;Integrated Security=True");
        sql.Open();

        string command =
            ("INSERT INTO Bookings( BookingName, BookingStart, BookingEnd, RoomID ) " +
             "VALUES ("
                + "'" + booking.BookingName + "'" + ", "   
                + "'" + booking.BookingStart  + "'" + ", " 
                + "'" + booking.BookingEnd + "'" + ", "
                        + booking.RoomID + ")");

        SqlCommand cmd = new SqlCommand(command, sql);                
        cmd.ExecuteNonQuery();            
    }

    public void Close()
    {
        sql.Close();
    }

Interface:

[OperationContract(Name="postmethod")]
    [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, UriTemplate = "postmethod/new")]

    void CreateBooking(Booking booking); 
}

Booking class:

[DataContract]
public class Booking
{
    [DataMember]
    public int BookingID { get; set; }

    [DataMember]
    public string BookingName { get; set; }

    [DataMember]
    public DateTime BookingStart { get; set; }

    [DataMember]
    public DateTime BookingEnd { get; set; }

    [DataMember]
    public int RoomID { get; set; }

}

However, whenever I call the method I am getting a 405 error. My question is, is the method above causing the error or is it something in the connection end of things? Thanks.

Answer 1

I have tried the above scenario and with few changes i got it working as shown below:

[OperationContract]
        [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, UriTemplate = "postmethod/new")]
        Booking CreateBooking(Booking booking); 

You can remove the WrappedRequest setting as you just have only 1 param.

When i perform a POST from Fidder with the below request i get a successful response:

POST http://localhost/SampleApp/Service1.svc/postmethod/new HTTP/1.1
Content-Type: application/json
Host: localhost
Content-Length: 144
Expect: 100-continue

{"BookingEnd":"\/Date(1332420656202+0000)\/","BookingID":1,"BookingName":"client sent","BookingStart":"\/Date(1332334256202+0000)\/","RoomID":2}

You can remove the name attribute in the OperationContract as well. If you are hosting in IIS then the address can be empty as the address is assigned by IIS.
