Making a Javascript call for JSON data in an ASP.NET MVC 3 application that is authenticated using Forms Authentication

Question

Making a Javascript call for JSON data in an ASP.NET MVC 3 application that is authenticated using Forms Authentication

My MVC 3 REST API features a straightforward controller called ApiController. Within this controller, there exists a method named Foo that accepts string data and returns a JSON result:

public class ApiController : Controller
{
    [HttpPost]
    public JsonResult Foo(string input)
    {
        ...
    }
}

My goal is to utilize a JQuery function to invoke Foo with user-provided information and exhibit the outcome.

The challenge is ensuring that only authorized users have access to Foo. What steps should I take within ASP.NET MVC 3 to address this? I'm considering implementing SSL and basic authentication, but I need guidance on how to implement it. Additionally, I am unsure if I need to develop my own password encryption method or if there is a way to leverage Forms Authentication.

Edit: It's important to note that my aim is to develop an API for third-party developers to utilize. For instance, allowing someone to create a browser extension similar to Rapportive that scans Gmail, sends the text to Foo, and displays the results in the browser.

Furthermore, I am concerned that using just Forms Authentication may transmit username and password details in plain text. How can I incorporate SSL to prevent this security risk?

To enhance security in your application, consider using FormsAuthentication along with the [Authorize] attribute. One approach is to create an AccountController with a LogOn action that can only be accessed via HTTPS. This controller allows clients to authenticate and receive an authentication cookie for accessing the API:

public class AccountController: Controller
{
    [HttpPost]
    [RequireHttps]
    public ActionResult LogOn(string username, string password)
    {
        // Validate credentials and provide an authentication cookie if they are correct
        // Return a response (possibly JSON) indicating the success or failure of the operation
    }
}

After setting up the LogOn action, you can secure other controller actions by adding the [Authorize] attribute:

public class ApiController : Controller
{
    [HttpPost]
    [Authorize]
    public JsonResult Foo(string input)
    {
        // Code implementation for the Foo method
    }
}

Clients will need to first call the LogOn action to obtain the authentication cookie, which must be included in subsequent API calls for authorization.

To achieve the desired functionality, consider utilizing the [Authorize] attribute. For more information and a practical example, refer to the resources available on MSDN: http://msdn.microsoft.com/en-us/library/system.web.mvc.authorizeattribute.aspx

With the [Authorize] attribute, you have the flexibility to grant access to specific users or users belonging to a particular role.

Upon creating a new ASP.NET MVC project (non-empty), the default Forms-based authentication mechanism will facilitate user authorization seamlessly.
