有没有一种方法可以连接到ASP中内置的SignalR Hub. NET从其他应用程序? [英] Is there a way to connect to SignalR Hub built in ASP. NET from other application?

问题描述

为了实现实时在线聊天，我已经有一些使用ASP .NET MVC和SignalR的Web应用程序. 我有SignalR ChatHub : Hub并从客户端连接到此集线器，如下所示: let hub = $.connection.chatHub并且运行良好. 如果我想在桌面应用程序中使用该中心怎么办?这甚至可能吗，这是一个好习惯吗?如果是，我该如何连接?有任何想法吗?谢谢！

For implmenting a real-time online chat, I already have some web application using ASP .NET MVC and SignalR. I have SignalR ChatHub : Hub and connect to this hub from the client side like following: let hub = $.connection.chatHub and it's working well. And what if I want to use this hub in desktop application? Is this even possible and is this a good practice? If yes, how do I connect to it? Any Ideas? Thanks!

推荐答案

存在一个.NET SignalR客户端，该客户端可用于允许桌面应用程序连接到SignalR集线器.可从NuGet获得.

A .NET SignalR client exists that can be used to allow a desktop application to connect to a SignalR hub. It is available from NuGet.

配置客户端以与您的Web客户端相同的方式连接到集线器，并且无论平台如何，所有连接的用户之间都将共享消息.

Configure the client to connect to the hub in the same way your web client does and messages will be shared between all connected users regardless of platform.

SignalR集线器和客户端必须为相同版本(请参见此处:

The SignalR hub and client must be the same version (see here: Connect to SignalR server in dotnet core from .NET client).

.NET 4.5 +

对于.NET 4.5+版本(不包括.NET Core)，您需要较旧的客户端:Microsoft.AspNet.SignalR.Client

For .NET versions 4.5+ (not including .NET Core) you require the older client: Microsoft.AspNet.SignalR.Client

可在此处找到文档和代码示例: https://docs.microsoft.com/zh-cn/aspnet/signalr/overview/guide-to-the-api/hubs-api-guide-net-client

Documentation and code samples are available here: https://docs.microsoft.com/en-us/aspnet/signalr/overview/guide-to-the-api/hubs-api-guide-net-client

ASP.NET Core

如果您的MVC应用程序使用的是ASP.NET Core，请改用以下程序包:Microsoft.AspNetCore.SignalR.Client

If your MVC application is using ASP.NET Core then use this package instead: Microsoft.AspNetCore.SignalR.Client

您可以在此处找到文档: https://docs.microsoft.com/zh-cn/aspnet/core/signalr/dotnet-client?view=aspnetcore-2.2

You can find documentation here: https://docs.microsoft.com/en-us/aspnet/core/signalr/dotnet-client?view=aspnetcore-2.2

示例-从桌面应用程序客户端调用服务器方法

以下来自.NET 4.5+文档:

The following is from the .NET 4.5+ documentation:

// Connect
var hubConnection = new HubConnection("http://www.contoso.com/");
IHubProxy stockTickerHubProxy = hubConnection.CreateHubProxy("stockTicker");
await hubConnection.Start();

// Call server method "JoinGroup" from client
stockTickerHubProxy.Invoke("JoinGroup", "SignalRChatRoom");
