In this article I will explain with an example, how to use the $http POST service with parameters in AngularJS.
This article will illustrate usage of AngularJS $http POST service with parameters by calling the Controller Action method in ASP.Net MVC Razor.
Note: For beginners in ASP.Net MVC, please refer my article ASP.Net MVC Hello World Tutorial with Sample Program example.
Following is a Model class named PersonModel with two properties i.e. Name and DateTime.
public class PersonModel
    /// Gets or sets Name.
    public string Name { get; set; }
    /// Gets or sets DateTime.
    public string DateTime { get; set; }
The Controller consists of two Action methods.
Action method for handling GET operation
Inside this Action method, simply the View is returned.
Action method for handling AngularJS AJAX operation
This Action method handles the call made from the AngularJS AJAX function from the View.
Note: The following Action method handles AJAX calls and hence the return type is set to JsonResult.
The value of the name parameter is assigned to the Name property of the PersonModel object along with the Current DateTime and finally the PersonModel object is returned back as JSON to the AngularJS AJAX function.
public class HomeController : Controller
    // GET: Home
    public ActionResult Index()
        return View();
    public JsonResult AjaxMethod(string name)
        PersonModel person = new PersonModel
            Name = name,
            DateTime = DateTime.Now.ToString()
        return Json(person);
Next step is to add a View for the Controller.

The View HTML Markup consists of an HTML DIV to which ng-app and ng-controller AngularJS directives have been assigned.
Note: If you want to learn more about these directives, please refer my article Introduction to AngularJS.
The HTML DIV consists of an HTML TextBox and a Button. The Button has been assigned AngularJS ng-click directive. When the Button is clicked, the ButtonClick function is executed.
Note: If you want to learn more about ng-click directive, please refer my article AngularJS: Implement Button click event using ng-click directive example.
Inside the ButtonClick function, the $http service is used to make an AJAX call to the Controller’s Action method. The $http service has following properties and methods.
1. method – The method type of HTTP Request i.e. GET or POST.
2. url – URL of the Controller’s Action method.
3. dataType - The format of the data i.e. XML or JSON.
4. data – The parameters to be sent to the Controller's Action method.
5. headers - List of headers to be specified for the HTTP Request.
Event Handler
1. success – This event handler is triggered once the AJAX call is successfully executed.
2. error – This event handler is triggered when the AJAX call encounters an error.
The response from the AJAX call is received in JSON format inside the Success event handler of the $http service and the result is displayed using JavaScript Alert Message Box.

            var post = $http({
                method: "POST",
                url: "/Home/AjaxMethod",
                dataType: 'json',
                data: { name: $scope.Name },
                headers: { "Content-Type": "application/json" }
            post.success(function (data, status) {
                $window.alert("Hello: " + data.Name + " .\nCurrent Date and Time: " + data.DateTime);
            post.error(function (data, status) {
    <div ng-app="MyApp" ng-controller="MyController">
        <input type="text" ng-model="Name"/>
        <input type="button" value="Submit" ng-click="ButtonClick()"/>
