I'm trying to invoke a WCF rest service as shown below:
[WebInvoke(UriTemplate = "Login", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
public string Process(string AuthenticationInfo)
{
I'm trying to invoke it using the following below in Fiddler 2:
User-Agent: Fiddler
Host: localhost
content-type: application/json;charset=utf-8
content-length: 0
data: {"AuthenticationInfo": "data"}
I have a breakpoint in the method, and it does hit the breakpoint, but the value for AuthenticationInfo is always null, and not "data".
What am I doing wrong?
Thanks.
The default "body style" of the [WebInvoke]
attribute is "Bare", which means that the input (in your case, "data"
) must be sent "as is". What you're sending is a wrapped version of the input (i.e., wrapped in an object whose key is the parameter name.
There are two ways you can make this work: either change the WebInvoke
declaration to include the BodyStyle parameter:
[WebInvoke(
UriTemplate = "Login",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.WrappedRequest)]
public string Process(string AuthenticationInfo)
Or you can change the request to send the parameter "bare":
POST .../Login HTTP/1.1
User-Agent: Fiddler
Host: localhost
Content-Type: application/json;charset=utf-8
Content-Length: 6
"data"
