i have wcf service hosed in sharepoint application. But when i try to call method from jquery it always fails.
I have tested service with such string:
ttp://localhost/_vti_bin/webservices/wcfservice.svc/**mex**
and have normal response.
WCF test client have response too.
But in my javascript code i recieve always error. Why? What i am doing wrong?
$.ajax({
url: "/_vti_bin/webservices/wcfservice.svc/HelloWorld",
dataType: 'json',
contentType: "application/json",
success: function (res) {
alert("good answer");
},
error: function (xhr) {
alert("error");
return;
}
});
Browser response:

Code of service:
[BasicHttpBindingServiceMetadataExchangeEndpoint]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
[ServiceContract]
public class WCFService
{
// To test this service, use the Visual Studio WCF Test client
// set the endpoint to http://<Your server name>/_vti_bin/WebServices/WCFService.svc/mex
[OperationContract]
//[WebGet(UriTemplate = "HelloWorld", 开发者_开发百科ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)]
[WebInvoke(RequestFormat = WebMessageFormat.Json, UriTemplate="/HelloWorldM", BodyStyle = WebMessageBodyStyle.Wrapped)]
public string HelloWorld()
{
return "Hello World from WCF and SharePoint 2010";
}
}
Try to use MultipleBaseAddressWebServiceHostFactory instead of MultipleBaseAddressBasicHttpBindingServiceHostFactory in SVC files.
