blocks|key|217090|text|是啊。您可以使用$.connection.hub.id。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|217091|entityMap^0|8|J|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

Yep. You can use <code>$.connection.hub.id</code>.

blocks|key|112|text|对于.NET客户端，它位于HubConnection继承的Connection对象上。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|113|Connection.ConnectionId|code-block|syntax|javascript|114|因此，通常可以在|115|hubConnection.ConnectionId|116|entityMap^0|D|D|T|A|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|V|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|W|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|X|8|@]|D|@]|E|$I|J]]|$1|O|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|P|$]]

For a .NET Client it is on the <code>Connection</code> object, inherited by <code>HubConnection</code>.

<pre><code>Connection.ConnectionId
</code></pre>

So typically can be found on

<pre><code>hubConnection.ConnectionId
</code></pre>

blocks|key|172|text|使用下面的代码，它适用于我。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|173|在hub类中。|174|+public+static+ConcurrentDictionary<string,+MyUserType>+MyUsers+=+new+ConcurrentDictionary<string,+MyUserType>();

use the following code it works for me.

in the hub class.

<pre><code> public static ConcurrentDictionary&lt;string, MyUserType&gt; MyUsers = new ConcurrentDictionary&lt;string, MyUserType&gt;();



 public override Task OnConnected()
 {
 MyUsers.TryAdd(Context.User.Identity.Name, new MyUserType() { ConnectionId = Context.ConnectionId,UserName=Context.User.Identity.Name });
 string name = Context.User.Identity.Name;

 Groups.Add(Context.ConnectionId, name);

 return base.OnConnected();
 }
</code></pre>

in the hub class file create the following class

<pre><code>public class MyUserType
{
 public string ConnectionId { get; set; }
 public string UserName { get; set; }

}
</code></pre>

and outside the hub class.

<pre><code> var con = MyHub1.MyUsers;
 var conId =con.Select(s =&gt; s.Value).Where(s =&gt; s.UserName == User.Identity.Name).FirstOrDefault();
</code></pre>

blocks|key|217239|text|这对我来说很有效：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|217240|var+hub+=+$.connection.someHub;
//+After+connection+is+started

This works for me: 

<pre><code>var hub = $.connection.someHub;
// After connection is started
console.log(hub.connection.id);
</code></pre>

Server : 
Context.ConnectionId 
=> "dJSbEc73n6YjGIhj-SZz1Q"

Client : 

<pre><code> this._hubConnection
 .start()
 .then(() =&gt; { 
 var hub = this._hubConnection ;
 var connectionUrl = hub["connection"].transport.webSocket.url ;
 console.log(connectionUrl);
</code></pre>

=> wss://localhost:5001/notify?id=dJSbEc73n6YjGIhj-SZz1Q 

you can extract the id.
(far to be a perfect solution)

blocks|key|292|text|要获得完整的集线器url，您可以说：hubConnection.connection.transport.webSocket.url|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|293|这类似于："wss://localhost:1234/myHub?id=abcdefg"|294|获取ID的正则表达式：|295|var+r+=+/.*\=(.*)/+var+id+=+r.exec(url)[1]|296|entityMap^0|I|1C|0|5|13|0|0|0|16|0^^$0|@$1|2|3|4|5|6|7|N|8|@$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Q|8|@$9|R|A|S|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|T|8|@]|D|@]|E|$]]|$1|J|3|K|5|6|7|U|8|@$9|V|A|W|B|C]]|D|@]|E|$]]|$1|L|3|-4|5|6|7|X|8|@]|D|@]|E|$]]]|M|$]]

To get the full hub url, you can say: <code>hubConnection.connection.transport.webSocket.url</code>

this is something like: <code>"wss://localhost:1234/myHub?id=abcdefg"</code>

Regex to get the ID:

<code>
var r = /.*\=(.*)/
var id = r.exec(url)[1]
</code>

I am using SignalR in my ASP.NET web application. Here I am calling client from outside to hub class using <code>IHubContext</code>. I need to get the current user's connection ID in order to send messages to the current user only. How can I get the connection ID on the client side?

how to get SignalR user connection id out side the hub class?

服务器

我在我的ASP.NET web应用程序中使用SignalR。在这里，我使用IHubContext从外部调用客户端到集线器类。我需要获取当前用户的连接ID，以便仅向当前用户发送消息。如何在客户端获取连接ID？
