调用Web API方法

Question

I am trying to call the DataByLocation with parameter but its calling DataByLocation function with no parameter. Am I missing something? Below is the code. Thanks in advance.

Js Code

 getData:function(){
        var _data = {_location:'ABC'};
        $.ajax({
            type: "POST",
            contentType: "application/json",
            url: 'ABService/api/ABService/DataByLocation',
            data: JSON.stringify(_data),
            success: this.receivedData                
        });
    }

Controller Code

[HttpPost]
public string DataByLocation(string _location)
{
    return _location;
}
[HttpPost]
public string DataByLocation()
{

    return "no parameter";
}

Config Code

    RouteTable.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = System.Web.Http.RouteParameter.Optional }
        );

Since you have not posted actual class name, i am assuming this to be TestController. Keeping that in mind, you can use following URLs for webapi. Assume , this is hosted in http://www.example.com`

If you need execute without id , then url will be.

http://www.example.com/api/Test/DataByLocation

If with id then url will remain same, but you need to pass post object as JSON.

EDIT

Since controller name is ABService , and virtual directory is ABService

URL will be http://www.example.com/ABService/api/ABService/DataByLocation
