- 聊天客户端：ConverseJS，内部使用 StropheJS
- 聊天服务器：Ejabberd 最新版本
- 聊天地点：NodeBB 网站。
为了让您了解问题的背景，我正在从服务器端代码连接到 XMPP，并将 JID、SID 和 RID 传递给客户端，从那里我使用 prebind / keepalive 为 true，并通过传递 JID、SID 和 RID 连接到聊天。连接成功。但是，当聊天名单加载时，我看不到用户在线（即使他们在线），没有设置图像（即使用户设置了他们的图片）。当我查看 Fiddler 来解决这个问题时，我发现对 XMPP 的第二个响应（获取用户详细信息，如状态、vcard 信息）为空白。但是，我无法理解出现空白响应的原因。你能告诉我为什么会这样吗？
以下是我通过Fiddler捕获的请求响应：
