推荐项目:WebSocket-Manager - 简单实时的.NET Core中间件
WebSocket-Manager是一个.NET Core库,用于简化WebSocket的使用。以下是一个如何使用WebSocket-Manager发送和接收消息的示例代码:
首先,安装NuGet包:
Install-Package WebSocketManager
然后,在你的Startup.cs文件中配置服务和中间件:
public void ConfigureServices(IServiceCollection services)
{
services.AddWebSocketManager();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseWebSockets();
app.UseWebSocketManager();
// 其余配置...
}
在你的控制器或中间件中,你可以这样使用WebSocket-Manager:
public class WebSocketTestController : Controller
{
private IWebSocketManager _webSocketManager;
public WebSocketTestController(IWebSocketManager webSocketManager)
{
_webSocketManager = webSocketManager;
}
public async Task SendMessage(string message)
{
await _webSocketManager.WebSocketConnections.BroadcastAsync(message);
}
public async Task ReceiveMessage()
{
var webSocket = await _webSocketManager.GetWebSocket();
var buffer = new byte[1024 * 4];
while (webSocket.State == WebSocketState.Open)
{
var result = await webSocket.ReceiveAsync(new ArraySegment<byte>(buffer), CancellationToken.None);
if (result.MessageType == WebSocketMessageType.Text)
{
var message = Encoding.UTF8.GetString(buffer, 0, result.Count);
// 处理接收到的消息
}
}
}
}
在这个示例中,SendMessage
方法使用_webSocketManager.WebSocketConnections.BroadcastAsync
来发送广播消息,而ReceiveMessage
方法使用WebSocket.ReceiveAsync
来接收客户端发送的消息。这个库简化了WebSocket的使用,使得在.NET Core应用中集成WebSocket变得更加容易。
