与signalR成角度：到同一路由的多个集线器连接

Question

I have my client code as below. I have a signalr route and hub connection name. I am able to connect to the hub and get events. Now I need to connect to one more hub for the same route to get more events.

  this.hubConnection = this.window.$.hubConnection();
    this.hubConnection.url = this.apiUrl  + "api/signalr";
    this.hubProxy = this.hubConnection.createHubProxy("Event1Hub");
    this.hubProxy = this.hubConnection.createHubProxy("Event2Hub"); // When I add this line it is overriding first hub and only connecting to Event2Hub.

I am using "signalr": "2.3.0",

Answer 1

You are creating a proxy for Event1Hub and then reassining that object instance with proxy for Event2Hub . If you want to communicate with both hubs you'll have to initialize separate proxy objects in order for this to work.

this.hubConnection = this.window.$.hubConnection();
this.hubConnection.url = this.apiUrl  + "api/signalr";
this.hubEvent1Proxy = this.hubConnection.createHubProxy("Event1Hub");
this.hubEvent2Proxy = this.hubConnection.createHubProxy("Event2Hub");

This way hubEvent1Proxy will provide Event1Hub communication while hubEvent2Proxy will provide Event2Hub communication.
