Question

在golang中我需要创建一个websocket连接并跟踪所有连接的用户，广播或用户到用户的通信等。作为我计划使用该连接的内存地址的每个用户的标识符。这种方法有什么缺点吗？在我看来，这不应该造成任何问题，因为每个套接字是在websocket连接结束时销毁的请求端的上下文中创建的，只要连接存活，程序就应该保留所有这些内存地址。

var Socket *socket //i did this in order Socket to be ready without init out of the box just like Mutex //check init function to see how i handle this

type socket struct {
    connectedUsers []*User
}

type User struct {
    Id   unsafe.Pointer
    Conn *websocket.Conn
}

func init() {
    var sock = new(socket)
    sock.connectedUsers = make([]*User, 0)
    Socket = sock
}

//NewConnection add a new *User into connected users list
func (*socket) NewConnection(sock *websocket.Conn) {
    usr:=new(User)
    usr.Conn=sock
    usr.Id=unsafe.Pointer(usr)
    Socket.connectedUsers=append(Socket.connectedUsers,usr)
}
//then i can do something like
//theOtherUser:=*(*websocket.Conn)(usr.Id)//this will give the connection of the user (hopefully)

最后我做了类似this的事情并且效果很好

获取指针地址并在上下文中用作唯一标识符是否安全？
