示例1: on_send
def on_send(self, callback):
"""Register a callback to be called on each send
There will be two arguments: the message being sent (always a list),
and the return result of socket.send_multipart(msg).
Non-copying sends return a MessageTracker object whose
`done` attribute will be True when the send is complete.
This allows users to track when an object is safe to write to
again.
The second argument will always be None if copy=True
on the send.
on_send(None) disables recv event polling.
Parameters
----------
callback : callable
callback must take exactly two arguments, which will be
