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

Mon Aug 3 20:12:00 BST 2009

Hi Cuong,

Thanks for the reply!  It turns out that I'm not only hitting this
problem with simple.publish, but also other methods.  For example,
when I try to declare an exchange, the same thing happens.  Am I
supposed to be acking responses to my method calls or something?

Sending:
{"version":"1.1", "method": "call", "params": ["exchange.declare", [0,
"gx.quincy.foo.g1", "fanout", false, true, false, false, true, []]],
"id": 0}
-----------------------
Response:
200 OK
[('date', 'Mon, 03 Aug 2009 18:55:47 GMT'), ('content-length',
'1074'), ('content-type', 'text/plain'), ('server', 'inets/5.1')]

{"version":"1.1","id":0,"error":{"name":"JSONRPCError","code":500,"message":"Internal
error","error":"{timeout,\n    {gen_server,call,\n
[<0.248.0>,\n         {jsonrpc,<<\"call\">>,\n             {obj,\n
            [{\"http_method\",<<\"POST\">>},\n
{\"http_query_parameters\",{obj,[]}},\n
{\"http_headers\",\n                   {obj,\n
[{\"user-agent\",<<\"python\">>},\n
{\"accept\",<<\"application/json\">>},\n
{\"content-type\",<<\"application/json\">>},\n
{\"content-length\",<<\"148\">>},\n
{\"accept-encoding\",<<\"identity\">>},\n
{\"host\",<<\"localhost:55672\">>}]}},\n
{\"remote_port\",59596},\n
{\"remote_peername\",<<\"0:0:0:0:0:0:0:1\">>},\n
{\"scheme\",<<\"http\">>}]},\n
[<<\"exchange.declare\">>,\n
[0,<<\"gx.quincy.foo.g1\">>,<<\"fanout\">>,false,true,false,false,\n
            true,[]]]}]}}"}}
