`Angularjs` call to `WebMethod` with `PARAMETERS`

Question

How to post parameters to [WebMethod] using angularjs.

My angularjs script is::

app.factory('checkAvabService', function ($http) {
    return {
        checkFare: function () {
            return $http.post('onewaydomflt.aspx/checkAvab', { 

             data:{test:"hello"} //post test as parameter to web method

          })
        }
    };
});

My Web Method is::

[System.Web.Services.WebMethod]
public static string checkAvab(string test)  // string test is not accept value "hello"
{
    string x = test;
    return x;
}

Here I am not getting test parameter value hello to WebMethod.

Whats wrong in this code.

Just pass data in the 2nd parameter of $http.post call which takes data in JSON format. There is no need to use data again in object which you are passing.

return $http.post('onewaydomflt.aspx/checkAvab', {test:"hello"})

@JBNizet Thanks man for heads up.. but may I know while posting any data to ASP.Net MVC -4 action, why we need to pass request body in stringified format. Just asking for curiosity..

I don't know anything about ASP.Net MVC -4, and am not sure what you mean by "stringified format".

@JBNizet I meant to say, before sending data to server I stringify it(JSON.strigify(data))..

JB Nizet Over a year ago

I don't see why this would be of any use. Angular transforms the objects passed to $http to JSON by default: docs.angularjs.org/api/ng/service/$http#default-transformations If the data property of the request configuration object contains an object, serialize it into JSON format.
