我希望匿名连接到Android Smack 4.1客户端的openfire服务器并使用AccountManager注册新用户（用户名=＆＃34; wq＆＃34;，密码=＆＃34; wq＆＃34;）然后断开连接以非匿名注册用户身份登录。
3.1.1 Registration with a Server
未注册实体与之互动时必须特别小心 服务器而不是服务。通常，服务器启用带内 注册，以便实体可以＆＃34; bootstrap＆＃34;他们参与 Jabber网络;这种引导发生在未注册的时候 和未经身份验证的实体打开与服务器的TCP连接 然后立即完成与服务器的注册用例 使用新注册的身份进行身份验证。如上所述，当一个 服务器收到IQ-get的注册信息，它应该是 假设请求实体未注册，除非该实体 已经过身份验证。根据本地服务提供，a 如果未注册，服务器可能会返回节错误 实体在验证之前尝试注册太多次，或者是否 实体成功后尝试注册第二个身份 完成注册用例;服务器也可以返回一个 如果未注册的实体也等待，则会出现流错误 在认证或尝试完成除以外的任务之前很久 成功完成注册使用后的身份验证 情况下。
连接构建器如下所示：
xmpptcpConnection = new XMPPTCPConnection(XMPPTCPConnectionConfiguration.builder()
.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
.setResource(resource)
.setHost(localhost)
.setServiceName(serviceName)
.setPort(port)
.setDebuggerEnabled(true)
.setSendPresence(true)
.build()
);
注册：
if (password != null && username != null) {
AccountManager accountManager = AccountManager.getInstance(xmpptcpConnection);
accountManager.sensitiveOperationOverInsecureConnection(true);
accountManager.createAccount(username, password);
}
else {
smackError("Username or password wrong");
}
但是我得到了错误的请求错误

如果我与非匿名帐户建立连接，我没有收到错误，仅在连接构建器中添加了：
.setUsernameAndPassword(username, password)
但我不想使用其他已经注册的帐户向服务器注册新用户。 有没有什么好的解决方案可以通过这种方式传递它？
答案 0 :(得分：3)
You have to separate connect().login() chain.
xmpptcpConnection.connect();
if (anonymous) {
AccountManager accountManager = AccountManager.getInstance(xmpptcpConnection);
accountManager.sensitiveOperationOverInsecureConnection(true);
accountManager.createAccount(username, password)
}
xmpptcpConnection.login(); //with old or newly created username, password from shared preferences
