rwbr / exmlrpc Goto Github PK

Hi

I get the following error when using exmlrpc with ejabberd.

I use ejabberd2.1.6 and erlang R14B03.
ejabberd.cfg contains

{4560, ejabberd_xmlrpc, [{maxsessions, 10}, {timeout, 5000}]}

Could you please tell me if this is a known problem or if there is something wrong? TIA.

last.fm uses the XMLRPC server at ws.audioscrobbler.com. Using the example Python code for accessing this server works fine, but using the equivalent for Erlang didn't work. Studying the output with Wireshark, I noticed that Erlang wasn't outputting a Host header, and started digging into the XMLRPC code. Hacking a Host header manually into the POST fixed the basic bug, but other issues cropped up (the request comes back as "HTTP/1.0 200 OK" not HTTP/1.1), and they all appeared to come back to being a result of manually building/parsing the HTTP request as opposed to using the inets http client, which would seems the sensible option to me!

Problem with rewriting the xmlrpc module like that is that call/3 and call/5 wouldn't work as inets won't let you specify the socket to use AFAIK, and I can't seem to figure out how to set KeepAlive with that, but it still seems like a sensible option.

Example code used for testing:

-module(lastfm).
-export([start/0]).

start() -> 
    io:format("~p~n", [artist()]).

artist() ->
    case xmlrpc:call("ws.audioscrobbler.com", 80, "/2.0/", {call, artist.search, [{struct,[{artist,"blah"}]}]}, false,
             10000) of
    {error, Reason} ->
        {error, Reason};
    {ok, Result} ->
        Result
    end.
