Question

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，我使用直接身份验证<浏览器提示jid / pwd 没有问题。但是，如果我在执行服务器端预绑定（uisng MatriX）之后将样本更改为使用Candy.Core.attach（几乎是直通Strophe.Connection.attach），我似乎陷入某种空闲循环每秒3次向XMPP服务器发送空消息。

当我使用Candy.Core.attach时，有什么想法导致这种循环以及为什么演示Candy UI没有出现？

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
    });

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

注意：前缀为“LIBS：”的条目来自strophe的低级别日志记录（级别，msg）。还应该注意的是，糖果演示将strophe.js包装成一个名为libs.bundle.js的更大的包。

Answer 1

通常，当您连接到BOSH连接管理器时，您可以在第一个节（会话创建请求）上设置wait属性。

XEP-0124 Session Creation Response

Strophe和Candy使用的默认值为60。你能确定MatriX在建立BOSH会话时使用的价值吗？

例如：

<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'/>

Answer 2

似乎Openfire v3.9.3 BOSH实施是“古怪的”＃39; MatriX开发人员能够解决这个问题。从MatriX v1.6.0.1开始，该方案已得到解决。
