GodletRouter
Introduction
GodletRouter is a HTTP request multiplexer. It matches the URL of each incoming request against a list of registered patterns and calls the handler for the pattern that most closely matches the URL.
GodletRouter provides a class HttpServer, which works over HttpListener. Clients can embed a HttpServer in their applications, which can be easily called by a browser or a curl client.
Samples
class Program
{
static void Main(string[] args)
{
HttpServer server = new HttpServer();
server.Start("localhost", 4006);
//add MiddleWares
server.AddMiddleWares(new LogMiddleWare());
//set common page handlers
server.SetHomePageHandler(new HomeHttpHandler());
server.SetPageErrorHandler(new PageErrorHandler());
//dispatch urls to handlers
server.AddHandler("/test", new TestHttpHandler());
server.AddHandler("/test/child", new TestChildHttpHandler());
// wait for system exit
while (true)
{
string text = Console.ReadLine();
if (text == "exit" || text == "quit")
{
server.Stop();
break;
}
Console.WriteLine("please type 'exit' or 'quit' to exit this application...");
}
}
}
//How to implement a http handler
class TestHttpHandler : AbstractHttpHandler
{
protected override void doGet(HttpListenerRequest request, HttpListenerResponse response) {
string responseString =
@"<html>
<head><title>doGet</title></head>
<body><h2>test doGet</h2></body>
</html>";
this.WriteString(response, responseString);
}
protected override void doPost(HttpListenerRequest request, HttpListenerResponse response)
{
string responseString =
@"<html>
<head><title>doPost</title></head>
<body><h2>test doPost</h2></body>
</html>";
this.WriteString(response, responseString);
}
}
When you run this application, you can try it now:
-
Visit the home page
-
Test "Get" method
-
Test "Post" method
curl -X POST http://localhost:4006/test -d 'FOO'
-
Test a subsidiary url request
-
Visit a unknown page
