Below is a simple HTTP server that answers a request from a browser with "Hello!":
from weightless import Reactor, Server, HttpProtocol, http, be class HelloWorld(object): def processRequest(self, *args, **kwargs): yield http.ok() yield http.headers('Content-Length', 6) yield 'Hello!' reactor = Reactor() dna = \ (Server(reactor, 8080), (HttpProtocol(), (HelloWorld(),) ) ) server = be(dna) reactor.loop()
Simply start this server with:
$ python httpserver.py
Next, use your browser to go to http://localhost:8080.
In practice, you would have the class HelloWorld in a separate file. We call the remaining things in httpserver.py the server configuration.
If you like to see large real-world server configurations, take a look at the example in Meresco: server.py.
