我正在尝试从facebook chat api获取好友列表，引用此答案Integrate Facebook chat in android with Asmack API。我无法理解如何获得受信任的商店密码和路径。因此，xmpp.connect（）给出了一个异常“无法连接到chat.facebook.com”。有人可以帮忙吗？ 在此先感谢： - ）
public void connectToFb() throws XMPPException {
ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com", 5222);
config.setSASLAuthenticationEnabled(true);
config.setSecurityMode(SecurityMode.required);
config.setRosterLoadedAtLogin(true);
config.setTruststorePath("/system/etc/security/cacerts.bks");
config.setTruststorePassword("");
config.setTruststoreType("bks");
config.setSendPresence(false);
try {
SSLContext sc = SSLContext.getInstance("TLS");
sc.init(null, MemorizingTrustManager.getInstanceList(this), new java.security.SecureRandom());
config.setCustomSSLContext(sc);
} catch (GeneralSecurityException e) {
Log.w("TAG", "Unable to use MemorizingTrustManager", e);
}
XMPPConnection xmpp = new XMPPConnection(config);
try {
xmpp.connect();
xmpp.login("username", "password"); // Here you have to used only facebookusername from facebookusername@chat.facebook.com
Roster roster = xmpp.getRoster();
Collection<RosterEntry> entries = roster.getEntries();
System.out.println("Connected!");
System.out.println("\n\n" + entries.size() + " buddy(ies):");
// shows first time onliners---->
String temp[] = new String[50];
int i = 0;
for (RosterEntry entry : entries) {
String user = entry.getUser();
Log.i("TAG", user);
}
} catch (XMPPException e) {
xmpp.disconnect();
e.printStackTrace();
}
}
