QuickBlox' QB.chat.addlistener 只是偶尔工作，不知道为什么或什么触发了它

Question

很难在看似随机的时间进行这项工作。当我进入聊天页面时，控制器激活，紧接着 before addlistener 和 after addlistener console.logs 触发，然后有时当我发送消息时，会收到包内容的控制台打印输出，但更多时候不是。有时，它会打印在触发发送消息而不是接收端的计算机控制台上。

不过，至少，每当我发送消息时，即使我没有得到包的控制台打印输出，我也会得到相应的 [QBChat RECV]:, [object Object] - 点击按钮十次，获得十个QBChat RECV。

太棒了！想通了。

您需要注意它发送的XML个包裹。发生的事情是，不知何故，当它第一次启动并运行并且与该帐户的相应 QB 聊天地址配合良好时，在那之后，在某个时候它开始附加一串数字-quickblox-数字（ 35896363-quickblox-20942 或其他）在地址的 'from' 字段中，这是我让我的听众听到的。令人困惑的是，这偶尔会起作用。

您不能对地址进行硬编码，因为末尾的这串数字会随着每次登录而变化。

相反，它暂时只监听参数为{name: 'message', type: 'chat'}的消息。

更好的方法是：

QB.chat.addListener( {name: 'message'}, function() {
            $log.debug(" main: QB listener by filter was triggered");
});

或者只是：

QB.chat.onMessageListener = showMessage;

该代码必须运行一次（在第一次初始化时，在系统加载时）。

onMessageListener 每次都会被触发。
addListener 只有在msg 的名称为'message' 时才会被触发。（侦听器过滤器）

那么你需要一个具有这样签名的函数：

function showMessage(userId, msg) {
    console.log('main.showMessage:: on message', msg)
}
