[英]SignalR self hosted windows service, listening for messages
I'm attempting to build a windows service that's self-hosting SignalR. 我正在尝试构建一个自托管SignalR的Windows服务。
I have read through tutorials such as SignalR Self-Host on ASP.Net 我已经阅读了ASP.Net上的SignalR Self-Host等教程
I'm noticing that, least it seems, that they're based around broadcasting messages, and can't seem to find anything around listening. 我注意到,至少看起来,它们是基于广播信息,并且似乎无法找到任何有关聆听的内容。
I need to listen to messages from within the service, as well as broadcast. 我需要收听服务中的消息以及广播。
We already have our backplane setup - it's the same one that the site uses. 我们已经有了背板设置 - 它与网站使用的设置相同。
In a web site I can join a group, via Javascript. 在一个网站上,我可以通过Javascript加入一个群组。 How do I join a group in a self-hosted SignalR service.
如何在自托管SignalR服务中加入组。
In a web site I register a callback on a hub. 在网站中,我在集线器上注册回调。 How do i register the same callback in a self-hosted service?
如何在自托管服务中注册相同的回调?
some example code that I have in place, for registering and starting SignalR is: 我有一些示例代码,用于注册和启动SignalR:
GlobalHost.DependencyResolver.UseSqlServer(Settings.Default.ISDBContext);
app.Map("/signalr", map =>
{
map.UseCors(CorsOptions.AllowAll);
HubConfiguration hubConfig = new HubConfiguration()
{
EnableDetailedErrors = true,
EnableJSONP = true,
};
map.RunSignalR(hubConfig);
});
I then start my webApp like this: 然后我像这样启动我的webApp:
SignalR = WebApp.Start<Startup>(options);
options are the url's i'm registering. 选项是我正在注册的网址。 Startup is the startup class containing the signalR mapping above.
Startup是包含上面signalR映射的启动类。
Little lost here as I haven't built a self-hosting service before 由于我之前没有建立自助托管服务,因此很少丢失
In general SignalR offers a real-time messaging environment with the benefit that it can push messages to clients without them requesting the update (you've read the intro, so enough for that). 通常,SignalR提供了一个实时的消息传递环境,它可以将消息推送到客户端,而无需他们请求更新(您已经阅读了介绍,因此足够了)。 Whether you start your self-host from within a service shouldn't make a difference.
无论您是从服务中启动自托管,都不应该有所作为。
From what I understand from your scenario: You need to consume the messages from the self-hosted service. 根据我对您的场景的理解:您需要使用来自自托管服务的消息。 I think you might only need a hint to the SignalR Desktop Client .
我想你可能只需要一个SignalR Desktop Client的提示。 I think your app/service should start off the service and then act as a client to the service itself.
我认为您的应用/服务应该从服务开始,然后充当服务本身的客户端。 This would be the cleanest approach.
这将是最干净的方法。
As the javascript client it acts as a consumer of the service with the same capabilities: 作为javascript客户端,它充当具有相同功能的服务的使用者:
HubConnection conn = new HubConnection("http://192.168.1.1:8080");
IHubProxy hub = conn.CreateHubProxy("ChatHub");
// call from hub to client
hub.On<string, string>("addMessage", (name, message) =>
{
// Handle incoming data update
});
and vice versa from the desktop client to the hub: 从桌面客户端到集线器,反之亦然:
await hub.Invoke<string, string>("Send", name, message);
To work with groups, the logic needs to be defined within your hub. 要使用组,需要在集线器中定义逻辑。 The documentation Working with groups gives an understandable overview.
文档使用组提供了可理解的概述。
