在浏览不同页面时重复使用signalR中的相同连接

I have an MVC project, with multiple pages.

我有一个MVC项目，有多个页面。

I have a long running process, which updates the client on its progress. However, this update is sent only to a single client, instead of broadcasting to all.

我有一个漫长的运行过程，它会更新客户端的进度。但是，此更新仅发送给单个客户端，而不是向所有客户端广播。

Clients.Client(ConnectionId).sendMessage(msg);

In my layout.cshtml, this is how I connect to the hub

在我的layout.cshtml中，这是我连接到集线器的方式

    var serverHub = $.connection.notifier;
    window.hubReady = $.connection.hub.start(function () { });

The problem is, when I navigate to another page, I no longer receive the messages from signalr, because the connection id has changed.

问题是，当我导航到另一个页面时，我不再收到来自signalr的消息，因为连接ID已更改。

How should I workaround this issue, such that my signalr hub can still send messages to a single client, while the client navigates from page to page.

我应该如何解决此问题，以便我的信号器中心仍然可以向单个客户端发送消息，同时客户端从一个页面导航到另一个页面。

You will want to create a server mapping of users to connection id's. See: SignalR 1.0 beta connection factory.

您将需要创建用户到连接ID的服务器映射。请参阅：SignalR 1.0 beta连接工厂。

You will want to let your users persist past an OnDisconnected event and when they connect with a different connection Id you can continue pumping data down to them.

您将希望让您的用户坚持通过OnDisconnected事件，当他们使用不同的连接ID连接时，您可以继续向他们提取数据。

So the thought process could be as follows:

所以思考过程可以如下：

Page loads, SignalR connection is instantiated
页面加载，SignalR连接被实例化
Once connection is fully started call => TryCreateUser (returns a user, whether it existed or it was created).
连接完全启动后，调用=> TryCreateUser（返回一个用户，无论它是否存在或是否已创建）。
Long Running process Starts
长时间运行过程开始
Client changes pages -> SignalR connection stops
客户端更改页面 - > SignalR连接停止
New Page loads, new SignalR connection is instantiated
新页面加载，新的SignalR连接被实例化
Once connection is fully started see if you have a cookie, session, or some type of data representing who you are => TryCreateUser(userData) (returns the user you created on the last page).
连接完全启动后，查看您是否有cookie，会话或某种类型的数据表示您是谁=> TryCreateUser（userData）（返回您在最后一页上创建的用户）。
Data continues pumping down to user.
数据继续向用户灌输。

Note: if you take an authentication approach you will have to be authenticated prior to starting a connection and that data cannot change during the lifetime of a SignalR connection, it can only be created/modified while the connection is in the disconnected state.

注意：如果采用身份验证方法，则必须在开始连接之前进行身份验证，并且在SignalR连接的生命周期内数据不能更改，只能在连接处于断开连接状态时创建/修改数据。
