使用 Smack 加载 vCard 信息时出错："EmptyResultIQ cannot be cast to org.jivesoftware.smackx.vcardtemp.packet.VCard"
Error loading vCard information using Smack: "EmptyResultIQ cannot be cast to org.jivesoftware.smackx.vcardtemp.packet.VCard"
我正在使用 smack 4.1.1
创建一个 android 聊天应用程序
我可以在本地测试服务器 (Openfire) 上加载用户 vcard。
但是现在在 ejabberd 服务器上，当我尝试加载 vcard 时，出现以下错误：

我实际上在另一个问题中写过这个问题。我希望我在这里重新发布修复程序不是野蛮人：
您可能面临的问题是 JID 的后缀。 entry.getUser() 方法 returns JID 为 user@example.com/Smack。要获取 vCard 详细信息，您需要以 user@example.com（不带 /Smack）的身份进行查询。试试看，如果有效请告诉我。
SENT: <iq to='jafar123@myserver.com' id='VSflA-26' type='get'><vCard xmlns='vcard-temp'/></iq>
RECV: <iq from='jafar123@myserver.com' to='mehdi123@myserver.com/roo' id='VSflA-26' type='result'/>
这似乎是服务器实现中的错误。 XEP-54 § 3.2 清楚地表明 vcard get 的结果必须是
- 一个有效的 vcard 结果 IQ
- 智商失误
If no vCard exists or the user does not exist, the server MUST return
a stanza error...
这里的服务器return一个空的IQ结果。
我建议将此报告给服务器开发人员。

我实际上在另一个问题中写过这个问题。我希望我在这里重新发布修复程序不是野蛮人：
您可能面临的问题是 JID 的后缀。 entry.getUser() 方法 returns JID 为 user@example.com/Smack。要获取 vCard 详细信息，您需要以 user@example.com（不带 /Smack）的身份进行查询。试试看，如果有效请告诉我。
SENT: <iq to='jafar123@myserver.com' id='VSflA-26' type='get'><vCard xmlns='vcard-temp'/></iq>
RECV: <iq from='jafar123@myserver.com' to='mehdi123@myserver.com/roo' id='VSflA-26' type='result'/>
这似乎是服务器实现中的错误。 XEP-54 § 3.2 清楚地表明 vcard get 的结果必须是
- 一个有效的 vcard 结果 IQ
- 智商失误
If no vCard exists or the user does not exist, the server MUST return a stanza error...
这里的服务器return一个空的IQ结果。
我建议将此报告给服务器开发人员。
