In my RESTful WCF Serice I need to pass a class as a parameter for URITemplate. I was able to pass a string or multiple strings as parameters. But I have a lot of fields are there to pass to WCF Service. So I have created a class and added all the fields as properties and then I want to pass this class as one paramenter to the URITemplate. When I am trying to pass class to the URITemplate I am getting error "Path segment must have type string". Its not accepting class as a parameter. Any idea how to pass class as a parameter. Here is my code (inputData is class)
[OperationContract]
[WebGet(UriTemplate = "/InsertData/{param1}")]
string saveData(inputData param1);
You actually can pass a complex type (class) in a GET request, but you need to "teach" WCF how to use it, via a QueryStringConverter. However, you usually shouldn't do that, especially in a method which will change something in the service (GET should be for read-only operations).
The code below shows both passing a complex type in a GET (with a custom QueryStringConverter) and POST (the way it's supposed to be done).
Passing a class (data contract) is only possible with POST or PUT request (
WebInvoke
). GET request allows only simple types where each must be part ofUriTemplate
to be mapped to parameter in the method.
