I'm doing some test over WCF REST WebServices and i'm stuck with the POST call. I've created a webservice that exposes some test data about the good ol' Northwind DB and since i wish to consume it locally from a test HTML page and since i'd like to test CORS capabilities, i made it CORS compliant by following these instruction http://enable-cors.org/server_wcf.html.
Unfortunately problems comes out when i make POST calls. Unlike GET calls (works very well), POST call throws this error:
What the hell is it? it seems that "Access-Control-Allow-Origin" header is not correctly managed client-side, beacuse in my EnableCrossOriginResourceSharingBehavior WCF class, the method "ApplyDispatchBehavior" (it filter "Access-Control-Allow-Origin" headers of the arrival requests) is hit when i make a POST call, but then Ajax call fails.
This is my jQuery Ajax post command:
//Create new object
var item = {
"CustomerId": "0",
"CompanyName": "prova"
};
//Push object
$.ajax({
type: "POST",
url: 'http://localhost:3434/NorthwindService.svc/Customer/Create',
crossDomain: true,
headers: {'Access-Control-Allow-Origin' : '*'},
data: JSON.stringify(item),
success: function (data) {
alert('ok!');
},
contentType: 'application/json; charset=utf-8',
dataType: 'json'
});
This is my WCF service Visual Studio 2013 project. To test it, you only have to set "NorthwindConnectionString" in web.config to an existing one. The webservice method that i've problem with, is the POST to the "http://localhost:3434/NorthwindService.svc/Customer/Create" method, all the others works fine. This is a preview of my method contract:
[OperationContract]
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, UriTemplate = "Customer/Create", BodyStyle=WebMessageBodyStyle.WrappedRequest)]
void NewCustomer(CustomerDTO customer);
Thanks in advance.
