Question

我正在尝试从ejabberd服务器向客户端手动发送消息。我创建了一个模块，并使用offline_message_hook将消息发送到FCM并对FCM响应采取了措施。如果我在FCM响应中没有收到任何错误，我尝试向发送方发送确认消息，该消息已发送到FCM。我正在使用erlang为ejabberd服务器创建模块。当我尝试发送这样的消息时：

ejabberd_ctl:send_message("normal", From, To, "ack", "101020").

我收到此错误：

exception error: undefined function ejabberdctl:send_message/5
   in function  mod_http_offline:create_message/1 (/opt/ejabberd-modules/mod_http_offline.erl, line 36)
   in call from ejabberd_hooks:safe_apply/4 (src/ejabberd_hooks.erl, line 236)
   in call from ejabberd_hooks:run_fold1/4 (src/ejabberd_hooks.erl, line 217)
   in call from ejabberd_sm:route/1 (src/ejabberd_sm.erl, line 146)
   in call from ejabberd_router:do_route/1 (src/ejabberd_router.erl, line 399)
   in call from ejabberd_router:route/1 (src/ejabberd_router.erl, line 92)
   in call from ejabberd_c2s:check_privacy_then_route/2 (src/ejabberd_c2s.erl, line 855)

错误似乎是该模块无法访问该函数，但我不知道要使用此函数需要包含哪个文件？当我尝试发送这样的消息时：

XmlBody = {xmlelement, "message", [{"id", []},{"type", "normal"}, {"from", From}, {"to", To}], [{xmlelement, "body", [], [{xmlcdata, <<"Test Message">>}]}]},
ejabberd_router:route(From, To, XmlBody);

我收到此错误：

                                          {"from",
                                           <<"e5d6d83c-ea77-4d10-aaac-4e0e38899ac2">>},

                                         [{xmlelement,"body",[],
                                           [{xmlcdata,<<"Test Message">>}]}]}) (src/ejabberd_router.erl, line 101)

   in call from ejabberd_c2s:check_privacy_then_route/2 (src/ejabberd_c2s.erl, line 855)

我不明白此错误。

是否可以从ejabberd服务器手动发送消息？
