Yes, and infact i am doing exactly this. But the accept call has no effect
it seems.
messenger = Messenger()
messenger.start()
messenger.subscribe(address)
message = Message()
while should_run:
messenger.recv()
while messenger.incoming:
try:
messenger.get(message)
messenger.accept()
except Exception, e:
print "Exception occurred while retrieving the message: " +
e
else:
print "Destination: " + message.address + "\n" + \
"Properties: " + str(message.properties) + "\n" + \
"Body: " + str(message.body) + "\n"
messenger.stop()
Output for the first time:
Destination: queue://test_accept.0
Properties: None
Body:
TestDataTestDataTestDataTestDataTestDataTestDataTestDataTestDataTestDataTestDataTestDataTestDataTestData
Destination: queue://test_accept.0
Properties: None
Body:
TestDataTestDataTestDataTestDataTestDataTestDataTestDataTestDataTestDataTestDataTestDataTestDataTestData
Destination: queue://test_accept.0
Properties: None
Body: SHUTDOWN
Output if I run the consumer again:
Destination: queue://test_accept.0
Properties: None
Body:
Destination: queue://test_accept.0
Properties: None
Body:
Destination: queue://test_accept.0
Properties: None
Body:
