[rabbitmq-discuss] Using rabbitmq-http2 (was: simple.publish over the JSON RPC interface)

Thu Aug 6 05:36:53 BST 2009

Hi Nathan,

because you're using json_rpc synchronous requests - call, you must
keep-alive it with steps 5s/request.
It think you have to set : session timeout = 5s (gen_server:call default
time out is 5000ms).

resp = proxy.rpccall("/rpc/rabbitmq", "open", ["guest", "guest",*5*,"/"])

i think you should not set http channel session timeout to large

Cuong,

This is result dump on my server when run *stupidRpc.py* script :

==================================
Calling /rpc/rabbitmq, open, ['guest', 'guest', 5, None]

connect: (localhost, 55672)
send: 'POST /rpc/rabbitmq HTTP/1.1\r\nHost:
localhost:55672\r\nAccept-Encoding: identity\r\nContent-Length:
84\r\nContent-Type: application/json; charset=UTF-8\r\nAccept:
application/json\r\nUser-Agent: python\r\n\r\n'
send: '{"version": "1.1", "params": ["guest", "guest", 9, null], "id": 0,
"method": "open"}'
-----------------------
reply: 'HTTP/1.1 200 OK\r\n'

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

got channel: B959C017343A362D4539668F9D6BA37F

==================================
Calling /rpc/B959C017343A362D4539668F9D6BA37F, poll, []

send: u'POST /rpc/B959C017343A362D4539668F9D6BA37F HTTP/1.1\r\nHost:

send: '{"version": "1.1", "params": [], "id": 1, "method": "poll"}'
-----------------------
