关于demo客户端连接不上本地搭建的ejabberd服务器

[yangtao639999]

自己的demo客户端连接不上本地搭建的ejabberd服务器,Psi软件都能连上，请教一下不知道哪里出了问题？代码如下：

var Hello = {
    connection: null,
    start_time: null,

    log: function (msg) {
        $('#log').append("<p>" + msg + "</p>");
    },

    send_ping: function (to) {
        var ping = $iq({
            to: to,
            type: "get",
            id: "ping1"}).c("ping", {xmlns: "urn:xmpp:ping"});

        Hello.log("Sending ping to " + to + ".");

        Hello.start_time = (new Date()).getTime();
        Hello.connection.send(ping);
    },

    handle_pong: function (iq) {
        var elapsed = (new Date()).getTime() - Hello.start_time;
        Hello.log("Received pong from server in " + elapsed + "ms.");

        Hello.connection.disconnect();
        
        return false;
    }
};

$(document).ready(function () {
    $('#login_dialog').dialog({
        autoOpen: true,
        draggable: false,
        modal: true,
        title: 'Connect to XMPP',
        buttons: {
            "Connect": function () {
                $(document).trigger('connect', {
                    jid: $('#jid').val(),
                    password: $('#password').val()
                });
                
                $('#password').val('');
                $(this).dialog('close');
            }
        }
    });
});

$(document).bind('connect', function (ev, data) {
    var conn = new Strophe.Connection(
        "http://127.0.0.1:5280/xmpp-httpbind");

    conn.connect(data.jid, data.password, function (status) {
        if (status === Strophe.Status.CONNECTED) {
            $(document).trigger('connected');
        } else if (status === Strophe.Status.DISCONNECTED) {
            $(document).trigger('disconnected');
        }
    });

    Hello.connection = conn;
});

$(document).bind('connected', function () {
    // inform the user
    Hello.log("Connection established.");

    Hello.connection.addHandler(Hello.handle_pong, null, "iq", null, "ping1");

    var domain = Strophe.getDomainFromJid(Hello.connection.jid);
    
    Hello.send_ping(domain);

});

$(document).bind('disconnected', function () {
    Hello.log("Connection terminated.");

    // remove dead connection object
    Hello.connection = null;
});

这段代码是连接ejabberd服务器，然后客户端这里显示一下ejabberd服务器回应的信息。运行以后什么反应都没有。。不显示回显信息。求救！！
