ZeroMQ comes with 5 basic patterns
- Synchronous Request/Response
- Asynchronous Request/Response
- Publish/Subscribe
- Push/Pull
- Exclusive Pair
Synchronous Request/Response
Client Requests
socket = context.socket(zmq.REQ)
socket.connect("tcp://wbhs-pkg.webhuis.nl:8080")
# Do 10 requests, waiting each time for a response
print("Sending request %s ..." % request)
socket.send(b"Hello")
# Get the reply.
message = socket.recv()
print("Received reply %s [ %s ]" % (request, message))
Server Replies
socket = context.socket(zmq.REP)
socket.bind("tcp://10.68.71.184:8080")
# Wait for next request from client
message = socket.recv()
print("Received request: %s" % message)
# Send reply back to client
socket.send(b"World")
Asynchronous Request/Response
Publish/Subscribe
socket = context.socket(zmq.PUB)
socket.bind("tcp://10.68.71.184:8080")
# Wait for next request from client
message = socket.recv()
print("Received request: %s" % message)
# Send reply back to client
socket.send(b"World")
