ZeroMQ with Producer-consumer

</step00>

Make sure need!

Let's see the map below:

</step01> If Your Data centre send many many data to a socket ...

Let's see the map again.

</step02> So what know how to use the ZeroMQ deal with your data ...

We assume the the socket.recv just like a client ... (Actually,it ' s server/client)

So the code can is like the below ...

</pre><pre name= "code" class= "python" >#!/usr/bin/pythonimport zmq import timecontext = Zmq. Context () socket = Context.socket (ZMQ. REQ) Socket.connect ("tcp://localhost:5559") for request in range (1,11):            socket.send (b "hello:-->%d"% request)        message = SOCKET.RECV ()        print ("Received reply%s [%s]"% (request,message))        Time.sleep (1)

</step03> Here,you has the data source ... But where is the ZeroMQ.

Good! Let ' s create one, Because it's work like a broker, so we name it as "broker.py"

#!/usr/bin/pythonimport Zmqcontext = zmq. Context () frontend = Zmq. Context () frontend = Context.socket (zmq. ROUTER) backend = Context.socket (zmq. DEALER) Frontend.bind ("tcp://*:5559") backend.bind ("tcp://*:5560") Poller = Zmq. Poller () Poller.register (FRONTEND,ZMQ. Pollin) Poller.register (BACKEND,ZMQ. Pollin) while True:        socks = Dict (Poller.poll ())        if Socks.get (frontend) = = Zmq. Pollin:                message = Frontend.recv_multipart ()                backend.send_multipart (message)        if Socks.get (backend) = = Zmq. Pollin:                message = Backend.recv_multipart ()                frontend.send_multipart (message)

</step04> we have a broker, so he/she looking for someone work for him/her ....

Here,we'll hire some worker ... (Actually,we make them ...)

How-to-make it ... Let's see the code below

#!/usr/bin/pythonimport Zmqcontext = zmq. Context () frontend = Zmq. Context () frontend = Context.socket (zmq. ROUTER) backend = Context.socket (zmq. DEALER) Frontend.bind ("tcp://*:5559") backend.bind ("tcp://*:5560") Poller = Zmq. Poller () Poller.register (FRONTEND,ZMQ. Pollin) Poller.register (BACKEND,ZMQ. Pollin) while True:        socks = Dict (Poller.poll ())        if Socks.get (frontend) = = Zmq. Pollin:                message = Frontend.recv_multipart ()                backend.send_multipart (message)        if Socks.get (backend) = = Zmq. Pollin:                message = Backend.recv_multipart ()                frontend.send_multipart (message)

</step05>

That ' s all! Thanks:)
