SignalR Console应用程序示例
是否有一个使用signalR将消息发送到.net集线器的控制台或winform应用程序的小示例?我尝试了.net示例,并查看了Wiki,但对我而言,集线器(.net)与客户端(控制台应用程序)之间的关系没有任何意义(找不到此类示例)。该应用程序是否仅需要连接集线器的地址和名称?
是否有人可以提供一小段代码来显示应用程序连接到集线器并发送“ Hello World”或.net集线器收到的内容?
PS。我有一个很好的标准集线器聊天示例,如果尝试在Cs中为其指定一个集线器名称,它将停止工作,即[HubName(“ test”)],您知道原因吗?
谢谢。
当前控制台应用程序代码。
static void Main(string[] args){
//Set connection
var connection = new HubConnection("http://localhost:41627/");
//Make proxy to hub based on hub name on server
var myHub = connection.CreateProxy("chat");
//Start connection
connection.Start().ContinueWith(task =>
{
if (task.IsFaulted)
{
Console.WriteLine("There was an error opening the connection:{0}", task.Exception.GetBaseException());
}
else
{
Console.WriteLine("Connected");
}
}).Wait();
//connection.StateChanged += connection_StateChanged;
myHub.Invoke("Send", "HELLO World ").ContinueWith(task => {
if(task.IsFaulted)
{
Console.WriteLine("There was an error calling send: {0}",task.Exception.GetBaseException());
}
else
{
Console.WriteLine("Send Complete.");
}
});
}
集线器服务器。(不同的项目工作区)
public class Chat : Hub{
public void Send(string message)
{
// Call the addMessage method on all clients
Clients.addMessage(message);
}
}

回答:
首先,您应该通过nuget在服务器应用程序上安装SignalR.Host.Self,在客户端应用程序上安装SignalR.Client:
PM>安装包SignalR.Hosting.Self-版本0.5.2
PM>安装包Microsoft.AspNet.SignalR.Client
然后将以下代码添加到您的项目中;)
(以管理员身份运行项目)
服务器控制台应用程序:
using System;using SignalR.Hubs;
namespace SignalR.Hosting.Self.Samples {
class Program {
static void Main(string[] args) {
string url = "http://127.0.0.1:8088/";
var server = new Server(url);
// Map the default hub url (/signalr)
server.MapHubs();
// Start the server
server.Start();
Console.WriteLine("Server running on {0}", url);
// Keep going until somebody hits 'x'
while (true) {
ConsoleKeyInfo ki = Console.ReadKey(true);
if (ki.Key == ConsoleKey.X) {
break;
}
}
}
[HubName("CustomHub")]
public class MyHub : Hub {
public string Send(string message) {
return message;
}
public void DoSomething(string param) {
Clients.addMessage(param);
}
}
}
}
客户端控制台应用程序:
using System;using SignalR.Client.Hubs;
namespace SignalRConsoleApp {
internal class Program {
private static void Main(string[] args) {
//Set connection
var connection = new HubConnection("http://127.0.0.1:8088/");
//Make proxy to hub based on hub name on server
var myHub = connection.CreateHubProxy("CustomHub");
//Start connection
connection.Start().ContinueWith(task => {
if (task.IsFaulted) {
Console.WriteLine("There was an error opening the connection:{0}",
task.Exception.GetBaseException());
} else {
Console.WriteLine("Connected");
}
}).Wait();
myHub.Invoke<string>("Send", "HELLO World ").ContinueWith(task => {
if (task.IsFaulted) {
Console.WriteLine("There was an error calling send: {0}",
task.Exception.GetBaseException());
} else {
Console.WriteLine(task.Result);
}
});
myHub.On<string>("addMessage", param => {
Console.WriteLine(param);
});
myHub.Invoke<string>("DoSomething", "I'm doing something!!!").Wait();
Console.Read();
connection.Stop();
}
}
}
