【中文标题】与 Facebook 聊天连接时远程连接失败【英文标题】：remote-connection-failed when connecting with Facebook Chat 【发布时间】：2012-01-25 05:27:45 【问题描述】：我正在尝试在我的 jQuery Mobile 上集成 Facebook Chat 并考虑关注
但是当我打开服务器（旁遮普语），并将以下必要的凭据放入与 facebook 相关的 javascript 中时，我收到 remote-connection-failed 错误 谁能告诉我缺少什么。
JID : XXX@chat.facebook.com
PASSWORD: <FacebookPassword>
传出和传入请求
SENT:<body rid='1283282620' xmlns='http://jabber.org/protocol/httpbind' to='chat.facebook.com' xml:lang='en' wait='300' hold='1' content='text/xml; charset=utf-8' ver='1.6' xmpp:version='1.0' xmlns:xmpp='urn:xmpp:xbosh'/>
RECV:<body xmlns='http://jabber.org/protocol/httpbind' type='terminate' condition='remote-connection-failed'/>

请有人建议我集成 Facebook 聊天的正确方法
【问题讨论】：
【参考方案1】：这是一个非常古老的问题，但我只是遇到了同样的问题，并发布此问题以防万一有人遇到同样的问题。
我还没有安装 pyopenssl，安装它立即解决了问题。
【讨论】：
是的，正如 HyperGeek 提到的，安装 pyopenssl 为我修复了它！【参考方案2】：你需要检查几件事：
punjab 返回的错误是远程连接失败。这意味着它无法打开与 chat.facebook.com 的连接。您的旁遮普语日志似乎不匹配，因为您没有尝试连接到 Facebook。 您可能会遇到跨域问题，这可能是您的客户端无法连接到旁遮普邦的原因。旁遮普在端口 5280 上运行，而您的客户端在端口 80 上提供服务。这是不同的服务，您的浏览器可能会阻止从端口 80 上提供服务的客户端连接回端口 5280。检查您的 Javascript 浏览器日志。我预计那里会出现错误。 Facebook 在使用代理时不支持标准身份验证。您将需要一个支持 X-FACEBOOK-PLATFORM SASL 身份验证机制的库。见：http://developers.facebook.com/docs/chat/【讨论】：
我只需要旁遮普语还是我也需要ejabberd？以上是关于与 Facebook 聊天连接时远程连接失败的主要内容，如果未能解决你的问题，请参考以下文章
