我正在使用 Candy.js (v1.7.1) 和 Openfire v3.9.3。运行 Candy 包中包含的示例 index.html，我没有问题（浏览器提示输入 jid/pwd）。但是，如果我在执行服务器端预绑定（uisng MatriX）之后将示例更改为使用 Candy.Core.attach（几乎是 Strophe.Connection.attach 的直通），我似乎陷入了某种空闲循环每秒向 XMPP 服务器发送 3 次空消息。

任何想法是什么导致了这种循环以及为什么我使用 Candy.Core.attach 时没有出现演示 Candy UI？

修改样本...

$(document).ready(function() {
    var httpbindUrl = 'http://xmpp.mydomain.net:7070/http-bind/';
    var chatRoom = 'testroom@conference.mydomain.net';

    // These values come from a REST call to our services that perform
    // the prebind authentication (using MatriX, obviously)
    var jid = 'someuser@mydomain.net/MatriX';
    var sid = 'b95ffa4';  // must be a string despite what candy's doc say
    var rid = 1983626985;

    Candy.init(httpbindUrl, {
        core: {
            debug: true,
            autojoin: [chatRoom]
        },
        view: { assets: './res/' }
    });

    Candy.Core.attach(jid, sid, rid); // this seems to cause some sort of looping to occur
    // Candy.Core.connect('someuser@mydomain.net', 'password'); // <-- this works as expected
    });

浏览器的控制台日志显示...

...continues in a similar pattern until I close the browser window.

注意：以“LIBS:”开头的条目来自 strophe 的低级日志记录（级别、味精）。还应该注意的是，糖果演示将 strophe.js 包装成一个更大的包，称为 libs.bundle.js。

看来 Openfire v3.9.3 BOSH 实现很“古怪”。MatriX 开发人员能够解决这个问题。从 MatriX v1.6.0.1 开始，该场景已解决。

通常，当您连接到 BOSH 连接管理器时，您可以在wait第一节（会话创建请求）上设置属性。

XEP-0124 会话创建响应

Strophe 和 Candy 使用的默认值为60. 您能否确认 MatriX 在建立 BOSH 会话时使用的值？

前任：

<body content='text/xml; charset=utf-8'
  from='user@example.com'
  hold='1'
  rid='1573741820'
  to='example.com'
  route='xmpp:example.com:9999'
  wait='60'
  xml:lang='en'
  xmpp:version='1.0'
  xmlns='http://jabber.org/protocol/httpbind'
  xmlns:xmpp='urn:xmpp:xbosh'/>
