推荐答案

这不是P2P，这种问题不适用，对吧?

我没看到问题.您的应用程序将所有注册的用户保留在一个词典中(如果您完全注册了)，而所有当前已签名的用户保留在另一本词典中.然后，一个新用户提交用户名，您将检测使用的用户名是否已经是当前用户名(出现在当前已签名用户的词典中).如果已经签名，则必须进行不同的连接.然后(可选)断开较旧的用户，并使用同一用户的新连接.

请注意，用户身份与会话无关(如果您基于TCP工作).从技术上讲，从两个不同的计算机/IP/套接字连接的同一用户是两个不同的实体. (可选)您可以通过两个不同的远程套接字(从个人身份的角度)继续使用同一用户的两个化身.这就是为什么我在上面说可选"的原因.

This is not P2P, where such issue should not apply, right?

I don''t see a problem. You application keeps all registered users in one dictionary (if you have registration at all), all currently signed users in another one. Then a new user submit user name, you detect if the same used is already current (present in dictionary of currently signed users). If it is already signed, you have to different connections. Then you (optionally) break the older one and work with the new connection of the same users.

Note, that user identity has nothing to do with the sessions (if you work TCP-based). Technically, the same user connected from two different computers/IPs/sockets are two different entities. Optionally, you can keep working with two incarnations of the same user (from the standpoint of personal identity) through two different remote sockets. That''s why I said "optionally" above.
