我正在使用 Ejabberd 和 Orbited，但我的 JavaScript 回调函数没有被调用时遇到了一些问题。以下是发生 TCPSocket 连接的 JavaScript 文件，我有两个回调函数，即
onSocketConnect: 当 Orbited 与 XMPP 服务器的 5222 端口建立连接时调用
onLoginSuccess: 在xmpp_client.login函数成功完成时调用
我面临的问题是连接成功，但我的回调仅在我使用 FireFox 时调用，而不是在使用 Safari 或 Chrome 时调用。我完全不知道是什么导致了这个问题，但我确信该方法xmpp_client.login确实被调用了，因为用户已登录并在 ejabberd 管理控制台中显示为在线。
TCPSocket = Orbited.TCPSocket;
Orbited.settings.port = 8000;
Orbited.settings.hostname = 'localhost';
document.domain = document.domain;
<script src='http://localhost:8000/static/protocols/xmpp/xmpp.js'></script>
//xmpp.js file is included after this which is available with the Orbited. I have not included the code here.
<% if current_user %>
<script>
notifier = ' ';
user = "<%= current_user.jabber_id %>";
alert(user);
password = '123456';
domain = XMPPDOMAIN;
/* function onLoginSuccess(){
$('.status').html("Connected and Logged In");
xmpp_client.set_presence('available');
} */
var onLoginSuccess = function(){
$('.status').html("Connected and Logged In");
}
function onLoginFailure(){
alert('User could not be logged in');
}
function connectSuccess(){
$('.status').html("Connection Successful.");
}
function connectFailure(){
$('.status').html("Connection Failed!");
}
function onSetupNotification(){}
xmpp_client = new XMPPClient();
xmpp_client.connect('localhost',5222);
xmpp_client.onPresence = function(ntype, from) {
alert('Presence message' + ntype + ' From :' + from)
}
xmpp_client.onSocketConnect = function(domain, connectSuccess, connectFailure){
var domain = XMPPDOMAIN;
$('.status').html('Connected');
alert(user);
if(domain)
{
xmpp_client.connectServer(domain, connectSuccess, connectFailure);
xmpp_client.login(user, password, onLoginSuccess, onLoginFailure);
xmpp_client.set_presence('available');
}
}
function send_message(id, msg){
var j_id = id + '@' + 'siddharth-ravichandrans-macbook-pro.local';
alert('jid_id' + j_id);
var status = xmpp_client.msg(j_id, msg);
alert(status);
}
xmpp_client.onMessage = function(jid, username, text) {
alert('message-recieved');
if ( $('.discussion-area').length > 0 ){
$('.discussion-area').append('<div class=\'new-message\'>' + text + '</div>');
return false;
}
}
/* self.login = function(nick, pass, s, f) {
conn.onread = setUser;
success = s;
failure = f;
user = nick;
bare_jid = nick + "@" + domain;
full_jid = bare_jid + "/Orbited";
self.send(construct(LOGIN, [user, pass]));
}
self.set_presence = function(status, status_msg) {
self.send(EXT_PRESENCE[0] + full_jid + EXT_PRESENCE[1] + room_jid + EXT_PRESENCE[3] + status + EXT_PRESENCE[4] + status_msg + EXT_PRESENCE[5]);
}
*/
</script>
<% end %>
这是我在安装轨道时得到的 xmpp.js 的一部分，为了测试我的请求是否真的到达，我在登录方法中添加了一个警报，如下所示
...
...
self.login = function(nick, pass, s, f) {
conn.onread = setUser;
success = s;
failure = f;
user = nick;
bare_jid = nick + "@" + domain;
full_jid = bare_jid + "/Orbited";
self.send(construct(LOGIN, [user, pass]));
alert("bazingaa");
}
self.connectServer = function(d, s, f) {
success = s;
failure = f;
doma
...
...
现在我不知道这是如何得到我的回调的，并且非常感谢对此的一些帮助。
谢谢
实际上，我发现删除 xmpp_client.set_presence 并将其移动到 onLoginSuccess 似乎已经成功了。我在登录方法调用后添加 set_presence 方法的那一刻，功能在 Chrome 中失败。那么为什么这会阻止它在成功登录时调用回调呢？
var onLoginSuccess = function(){
$('.status').html("Connected and Logged In");
xmpp_client.set_presence('available');
}
xmpp_client.onSocketConnect = function(domain, connectSuccess, connectFailure){
var d = "";
$('.status').html('Connected');
xmpp_client.connectServer(d, connectSuccess, connectFailure);
xmpp_client.login(user, password, onLoginSuccess, onLoginFailure);
//xmpp_client.set_presence('available');
}
帮助！
