My first WEB servicee usinf Visual Studio 2013 Express WEB, and I can't make it restfull. basically want to return a json string and got the following service definition;
[OperationContract]
[WebInvoke(Method = "GET",
ResponseFormat = WebMessageFormat.Json, UriTemplate = "Name")]
string Name();
Implementation of Name just returns a string which is shown when I Invoke the function through the WCF Test Client, but calling the http://localhost:58116/Service1.svc/Name returns nothing. I was expecting a json representation of the Name.
Any idea's?

I have a wcf service, which I made restfull, but editing the intereface and the webconfig.
In the interface, I have the following:
[ServiceContract]
public interface ITsmApi
{
[OperationContract]
[WebInvoke(UriTemplate = "/GetOrganizationNo", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Xml, Method = "POST")]
string GetOrganizationNo(CustomerNoInput input);
}
I would like if it is possible that I call the webservice function in this manner:
http://foo.example/api/v1/accounts/3
I would like that my URL link to the functions don't look like this:
http://servername.com/MyApi/MyApi.svc/AddPerson - meaning I would like to not have the SVC extension. Is that possible at all?
I have suspicion that I have to use service contract namespace, but I can't find what the procedure is?
I have WCF webservice that has contract like this
[OperationContract]
void UpdateEncounterStatus(int BookingID, string BookingStatus);
and in the class
[WebInvoke(Method = "POST",
ResponseFormat = WebMessageFormat.Json,
UriTemplate = "UpdateEncounterStatus/{BookingID}/{BookingStatus}")]
public void UpdateEncounterStatus(int BookingID, string BookingStatus)
but when call it , I get
Operation 'UpdateEncounterStatus' in contract 'IPMA' has a path variable named 'BookingID' which does not have type 'string'. Variables for UriTemplate path segments must have type 'string'.
and when change the parameter to string I got
method not allowed
any idea how to fix that
You can use only string types for the parameters that comes in the route of UriTemplate. In your example BookingID is integer and it comes in the route so it won't work. If you move BookingID to querystring them things will work.
See this thread for more details.
I have a big problem.
I created a WCF service.My POST declaration looks like this:
[OperationContract]
[WebInvoke(UriTemplate = "json/put",
Method = "POST",
BodyStyle = WebMessageBodyStyle.Wrapped,
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json)]
string PutData(string jsonText);
I was expecting that when I'm sending data (I'm using fiddler2 to test it) that it will automaticly "put" into the jsonText variable.
The service works, but there is no data :(.
Can anybody help? The whole project
WCF expects the JSON payload to be deserialized into a type. Try creating a class that is shaped like your JSON payload and use that as the parameter type.
I created a REST GetTime Service in WCF and the service returns JSON as the response message. Also the WebMessageBodyStyle is set to wrapped so it would have an ID associated with that data it returns. But when I use Fiddler to test my service the response string is:
{"GetTimeResult":"2010614104013"}
As the response above the ID of the string is GetTimeResult, I'm wondering is there any way on changing that bit of test to timestamp. So it looks like this:
{"timestamp":"2010614104013"}
Cheers.
If you are using the DataContract/DataMember attributes in your code, you add a name (as well as some other named parameters).
[DataMember(Name = "timestamp")]
public string GetTimeResult
As pointed out in this article, suppose you are not using a data member explicitly in a data contract and want to return, say, a timestamp as a simple string for the response. Just use the annotation [return: MessageParameter(Name = "timestamp")] with your operation contract method:
[OperationContract]
[WebInvoke(Method = "GET", UriTemplate = "/timestamps", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
[return: MessageParameter(Name = "timestamp")]
string GetStringTimestamp();
When using the following interface to talk to PHP from .NET, .NET builds the request body XML with parameter names barcode and branch. The parameter names should be Barcode and Branch. Yes, the PHP server is case sensitive.
Am I forced to capitalise my parameter names? or can I specify names using attributes?
Many Thanks

[ServiceContract]
public interface IStockEnquiryService
{
[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "")]
Branches GetStockInfo(string barcode, string branch);
}
Try applying the MessageParameterattribute to the method arguments and specify the right case in its Name property.
