signalr组添加 [英] signalr group add

问题描述

我可以添加例如用户名代替的 connection.id 的。它的工作原理？我问这是因为过度的ConnectionId我不能发送通知给用户，因为总的ConnectionId是变化？

can i add e.g. username instead of connection.id. does it work? i'm asking this because over ConnectionId i can't send notification to the user, because ConnectionId always is changes?

Groups.Add（my_username，MyGroup1的）;

Groups.Add("my_username", "mygroup1);

推荐答案

没有你不行，你必须使用的ConnectionId。但是，您可以做到以下几点。

No you cannot, you must use a ConnectionID. You can however do the following.

在集线器商店的用户列表映射到连接ID：

On your hub store a list of users mapped to connection IDs:

static ConcurrentDictionary<string, User> _users = new ConcurrentDictionary<string, User>();

然后，客户端连接启动后，你可以调用的方法，如：

Then after a client connection has been started you can call into a method like:

myHub.server.createUser("MyUsername");

当然，在服务器上你必须：

Of course on the server you'd have:

public void createUser(string userName) 
{
    // You'd create a User class that had both of the following properties
    var user = new User
    {
        UserName = userName,
        ConnectionID = Context.ConnectionId
    };
    _users.TryAdd(user.ConnectionID, user);        
}

所以每当你想通过查找连接ID的用户，你仍然有他/她通过_users词典的用户名的情况下。

SO whenever you want to lookup a user via connection ID you still have context of his/her username via the _users dictionary.
