将登录信息与套接字相关联？

[英]Associating login information with a socket?

原文 2011-12-31 08:20:27 0 2 c/ sockets/ login/ winsock

I'm writing a server that needs to know if you are logged in or not. 我正在编写一个服务器，该服务器需要知道您是否已登录。 To log in, the user sends his username and password as a packet through a socket. 要登录，用户将其用户名和密码作为数据包通过套接字发送。 Based on that socket, how can I tell if the user has been logged in? 基于该套接字，如何确定用户是否已登录？

Should I be associating login information with the socket - at that low a level? 我应该将登录信息与套接字相关联吗？

Better yet, is there a simple solution to this problem that I'm missing? 更好的是，是否存在针对我所缺少的此问题的简单解决方案？

I would just create a struct that groups information about the user with the socket. 我只是创建一个struct ，用套接字将有关用户的信息分组。

It's something I do with a User or Player class when writing in C#, no reason you can't translate that to C. 在用C＃编写时，这是我对User或Player类所做的事情，没有理由不能将其转换为C。

All you need to do is keep a structure (array, hash, map, whatever; array is simple, hash would more efficient, but hardly available in C), where you store your sockets ids (in C each socket has an int identifier like file), along with all the other information, you would like to have about every single connection/user. 您需要做的就是保持一个结构（数组，哈希，映射等；数组简单，哈希效率更高，但在C中几乎不可用），在此存储套接字ID（在C中，每个套接字都有一个int标识符，例如文件）以及所有其他信息，您希望拥有每个连接/用户。

Each time the package comes you have to lookup the data in the structure. 每次打包时，您都必须在结构中查找数据。
