17.5.1 asyncore Example basic HTTP client

Here is a very basic HTTP client that uses the `dispatcher` class to implement its socket handling:

    import asyncore, socket

    class http_client(asyncore.dispatcher):

        def __init__(self, host, path):
            asyncore.dispatcher.__init__(self)
            self.create_socket(socket.AF_INET, socket.SOCK_STREAM)
            self.connect( (host, 80) )
            self.buffer = 'GET %s HTTP/1.0\r\n\r\n' % path

        def handle_connect(self):
            pass

        def handle_close(self):
            self.close()

        def handle_read(self):
            print self.recv(8192)

        def writable(self):
            return (len(self.buffer) > 0)

        def handle_write(self):
            sent = self.send(self.buffer)
            self.buffer = self.buffer[sent:]

    c = http_client('www.python.org', '/')

    asyncore.loop()
