支持X-FACEBOOK-PLATFORM的带Java Asmack库的XMPP
我正试图在Android上与Smack库进行Facebook聊天。我已经阅读了Facebook上的内容，但我不明白如何使用该库通过Facebook的身份验证 有人能告诉我如何做到这一点吗 更新：根据no.good.at.coding答案，我将此代码改编为Asmack库。所有工作正常，但我收到的登录响应：未授权。以下是我使用的代码：支持X-FACEBOOK-PLATFORM的带Java Asmack库的XMPP,java,android,facebook,xmpp,smack,Java,Android,Facebook,Xmpp,Smack,我正试图在Android上与Smack库进行Facebook聊天。我已经阅读了Facebook上的内容，但我不明白如何使用该库通过Facebook的身份验证 有人能告诉我如何做到这一点吗 更新：根据no.good.at.coding答案，我将此代码改编为Asmack库。所有工作正常，但我收到的登录响应：未授权。以下是我使用的代码： public class SASLXFacebookPlatformMechanism extends SASLMechanism { private st

如果（0你想做什么
如果您只想登录FB聊天，您可以像其他任何XMPP服务器一样连接到FB
我会查看并使用聊天API中的“使用用户名/密码进行身份验证”，这是Smack支持的。除非我想编写FaceBook应用程序。然后我会尝试使用“使用FaceBook平台进行身份验证”登录
所以，只需使用Smack连接到FB聊天，就像使用普通的Jabber客户端一样
对于用户名，请使用您的Facebook用户名。（请参阅）
对于域，请使用：chat.facebook.com
