11.25.1 asyncore Example basic HTTP client
</H2>
<P>
As a basic example, below is a very basic HTTP client that uses the
<tt class="class">dispatcher</tt> class to implement its socket handling:
<P>
<div class="verbatim"><pre>
class http_client(asyncore.dispatcher):
def __init__(self, host,path):
asyncore.dispatcher.__init__(self)
self.path = path
self.create_socket(socket.AF_INET, socket.SOCK_STREAM)
self.connect( (host, 80) )
self.buffer = 'GET %s HTTP/1.0\r\n\r\n' % self.path
def handle_connect(self):
pass
def handle_read(self):
data = self.recv(8192)
print data
def writable(self):
return (len(self.buffer) > 0)
def handle_write(self):
sent = self.send(self.buffer)
self.buffer = self.buffer[sent:]
</pre></div>
