SyntaxTree.FastSpring

SyntaxTree.FastSpring is a C# helper library to validate the different requests FastSpring can send.

It works on .NET 3.5, .NET 4.0 and .NET 4.5. It supports both ASP.NET MVC and the ASP.NET WebForms.

API

For ASP.NET MVC.

namespace SyntaxTree.FastSpring
{
	public sealed class HttpRequestBaseExtensions
	{
		public static bool IsValidNotification (this HttpRequestBase request, string privateKey) {}
		public static bool IsValidLicenseRequest (this HttpRequestBase request, string privateKey) {}
	}
}

Test the validity of a request.

Usage from a controller:

using SyntaxTree.FastSpring;

public class NotificationController : Controller
{
	[HttpPost]
	public ActionResult NotifyOrder(
		string customerCompany,
		string customerEmail,
		string customerFirstName,
		string customerLastName,
		string customerPhone,
		string orderId)
	{
		const string privateKey = "75f0fff79f988c10b2c4f6315aec5a86";

		if (!Request.IsValidNotification(privateKey))
		{
			// ...
		}

		// ...
	}
}

The API for the ASP.NET WebForms is exactly the same except that we define the extension methods on the type System.Web.HttpRequest.
