Question

目前我正在使用ejabberd 14.05服务器并使用它的mod_rest模块根据来自第三方Web服务的特定条件更新用户在服务器中的存在。但我无法发布存在节来更新用户的存在。以下是我的发现。

命令用于通过mod_rest调用presence节。 curl --verbose --data＆＃34; World＆＃34; -X POST servername：5280 / rest / -H＆＃34; Content-Type：text / xml＆＃34; -H＆＃34;接受：application / xml＆＃34;

它以某种方式无法解析该节。不知道为什么会发生这种情况:(这方面的任何指针都很有用。另请告诉我，有任何其他方法可以提供帮助。

编辑1：CURL存在一些问题。所以我在chrome中切换到POSTMan客户端。现在这个节至少被解析了。现在的问题是消息节对我有用，但Presence节对我不起作用。我现在能够建立客户端到服务器会话。任何人都可以帮助我。

mod_admin_extra.erl中set_presence方法的代码

命令定义

#ejabberd_commands{name = set_presence,
                    tags = [session],
                    desc = "Set presence of a session",
                    module = ?MODULE, function = set_presence,
                    args = [{user, string}, {host, string},
                            {resource, string}, {type, string},
                            {show, string}, {status, string},
                            {priority, string}],
                    result = {res, rescode}},

指挥机构截至目前，我评论了大部分身体。一旦我得到有效的Pid，我将取消注释剩下的代码。

set_presence(User, Host, Resource, Type, Show, Status, Priority) ->
    Pid = ejabberd_sm:get_session_pid(User, Host, Resource),
%%    USR = User ++ "@" ++ Host ++ "/" ++ Resource,
%%    US = User ++ "@" ++ Host,
%%    Message = {route_xmlstreamelement,
%%             {xmlel, <<"presence">>,
%%              [{<<"from">>, USR}, {<<"to">>, US}, {<<"type">>, Type}],
%%              [{xmlel, <<"show">>, [], [{xmlcdata, Show}]},
%%               {xmlel, <<"status">>, [], [{xmlcdata, Status}]},
%%               {xmlel, <<"priority">>, [], [{xmlcdata, Priority}]}]}},

%%    ?INFO_MSG("Message : ~p~n",[Message]),
    ?INFO_MSG("Pid : ~s~n",[Pid]).
%%    Pid ! Message.

用法

su - root set_presence 2067343756 host 5599628551424712277712378 subscribed dnd Im_away_25_minutes 127

输出

Problem 'error undef' occurred executing the command.

Answer 1

我不确定为什么你需要发送一个存在节。

仅发送存在节不足以模拟用户存在。仍然没有任何与该存在节相关联的XMPP会话。

是的，您之前在套接字上发送了错误的XML数据。

存在Stanze for ejabberd不能通过mod_rest模块工作
