SignalR 2 连接未保留

Question

我设置了示例 SignalR 中心 ChatHub，添加了连接列表。当它运行 OnConnected 时，我看到它被添加到列表中。但是，当我在另一个浏览器中打开该页面时（期望列表现在有 2 个连接，我在列表中看到 0 个连接）。 ChatHub 是否根据请求实例化？

    List<string> connections = new List<string>();
    public override Task OnConnected()
    {
        connections.Add(Context.ConnectionId);
        return base.OnConnected();
    }

Answer 1

是的，为每个请求创建一个集线器实例。

specifically:

You don't instantiate the Hub class or call its methods from your own code on the server; all that is done for you by the SignalR Hubs pipeline. SignalR creates a new instance of your Hub class each time it needs to handle a Hub operation such as when a client connects, disconnects, or makes a method call to the server.
