要简化C# WebSocket服务器的代码,可以使用一些现成的库和框架,例如Microsoft.AspNetCore.Http.WebSocket
。以下是一个简单的示例,展示了如何使用ASP.NET Core创建一个基本的WebSocket服务器:
Microsoft.AspNetCore.Http.Abstractions
Microsoft.AspNetCore.Http.Core
Microsoft.AspNetCore.WebSockets
Startup.cs
的文件,并添加以下内容:using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using System.Threading.Tasks;
namespace WebSocketServer
{
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddControllers();
services.AddEndpointsApiExplorer();
services.AddSwaggerGen();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseSwagger();
app.UseSwaggerUI();
}
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
endpoints.MapWebSocket("/ws", async (client, context) =>
{
await Echo(client, context);
});
});
}
private async Task Echo(WebSocketClient client, WebSocketContext context)
{
byte[] buffer = new byte[1024 * 4];
WebSocketReceiveResult result;
do
{
result = await client.ReceiveAsync(new ArraySegment<byte>(buffer), CancellationToken.None);
if (result.CloseStatus != null)
{
break;
}
await client.SendAsync(new ArraySegment<byte>(buffer, 0, result.Count), result.CloseStatus.Value, CancellationToken.None);
}
while (!result.CloseStatus.HasValue);
await client.CloseAsync(result.CloseStatus.Value, result.CloseStatusDescription, CancellationToken.None);
}
}
}
这个示例中,我们创建了一个简单的WebSocket服务器,监听/ws
路径。当客户端连接到该路径时,服务器会将接收到的消息原样发送回客户端。
Program.cs
的文件,并添加以下内容:using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Hosting;
namespace WebSocketServer
{
public class Program
{
public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
});
}
}
Program.cs
文件,启动WebSocket服务器。现在,你已经创建了一个简单的C# WebSocket服务器。你可以根据需要扩展此示例,例如添加身份验证、消息处理等。
