我正在开发一个通用库，用于通过BOSH服务与xmpp用户进行通信。我使用Strophe.js
我无法理解为什么在课堂上BoshCommunicator方法onConnect我有一个Strophe对象，但没有像预期的那样BoshCommunicator。
当我在console.log（这个）时，我得到了对象{service =“http：// myboshim / http-bind”，jid =“aivaras37 @ myboshim / 29785298701381498988721337”，rid = 4092107607，more ...}
此外，在建立连接之前，我为BoshCommunicator类设置了listener属性。当我在console.log（this.listener）中我得到了未定义，但是如果我在connect（）方法中调用console.log（this.listener），我会得到预期的侦听器对象转储。你能解释一下如何在BoshCommunicator.prototype.onConnect（）中获得初始化的BoshCommunicator吗？另外请解释为什么我松开了我的物体并改为使用Strophe。
这是我使用的特定代码：
function BoshCommunicator(boshUri, host)
{
this.connection = null;
this.boshUri = null;
this.host = null;
this.listener = null;
this.setBoshUri(boshUri);
this.setHost(host);
}
BoshCommunicator.prototype.setBoshUri = function(boshUri)
{
this.boshUri = boshUri;
};
BoshCommunicator.prototype.setHost = function(host)
{
this.host = host;
};
BoshCommunicator.prototype.setListener = function(listener)
{
this.listener = listener;
this.listener.setListenHost(this.host);
};
BoshCommunicator.prototype.connect = function(jid, jpass)
{
this.connection = new Strophe.Connection(this.boshUri);
this.connection.connect(jid, jpass, this.onConnect);
};
BoshCommunicator.prototype.onConnect = function(status)
{
if (status === Strophe.Status.CONNECTED) {
console.log("Send me messages!");
console.log(this); // dumps strophe object. Paste from console: Object { service="http://myboshim/http-bind", jid="aivaras37@myboshim/29785298701381498988721337", rid=4092107607, more...}
console.log(this.listener); // undefined - how come?
this.connection.addHandler(this.listener.onReceivedMessage, null, 'message', null, null, null);
this.connection.send($pres().tree());
}
};
function MessageListener()
{
this.host = null;
}
MessageListener.prototype.setListenHost = function(host)
{
this.host = host;
};
function ReceivedMessageNotify()
{
MessageListener.call(this);
}
ReceivedMessageNotify.prototype = new MessageListener();
ReceivedMessageNotify.prototype.constructor = ReceivedMessageNotify;
ReceivedMessageNotify.prototype.onReceivedMessage = function(message)
{
console.log(message);
var elems = message.getElementsByTagName('body');
var body = elems[0];
if (Strophe.getText(body).length > 0) {
this.sendNewMessageNotify(message.getAttribute('from'), Strophe.getText(body));
}
return true;
};
ReceivedMessageNotify.prototype.sendNewMessageNotify = function(sender, messageBody)
{
alert("New message: " + sender + " wrote: " + messageBody);
};
$(document).ready(function() {
var communicator = new BoshCommunicator('http://myboshim/http-bind', 'myboshim');
communicator.setListener(new ReceivedMessageNotify());
communicator.connect('jabberId', 'accPasswd');
});
