在C#中,处理WebSocket服务器的异常主要涉及到以下几个方面:
public async Task HandleWebSocketAsync(HttpContext context, WebSocket webSocket)
{
try
{
// WebSocket连接处理逻辑
}
catch (Exception ex)
{
// 处理异常,例如记录日志、发送错误消息等
Console.WriteLine($"Error: {ex.Message}");
}
}
IExceptionFilter
接口来创建全局异常过滤器。例如:public class GlobalExceptionHandler : IExceptionFilter
{
public void OnException(ExceptionContext context)
{
// 处理异常,例如记录日志、发送错误消息等
Console.WriteLine($"Global Error: {context.Exception.Message}");
}
}
然后,在Startup.cs
文件中注册全局异常过滤器:
public void ConfigureServices(IServiceCollection services)
{
services.AddControllersWithViews()
.AddRazorPages()
.AddExceptionFilter<GlobalExceptionHandler>();
}
private static readonly NLog _logger = LogManager.GetCurrentClassLogger();
public async Task HandleWebSocketAsync(HttpContext context, WebSocket webSocket)
{
try
{
// WebSocket连接处理逻辑
}
catch (Exception ex)
{
_logger.Error(ex, "Error occurred while handling WebSocket connection.");
}
}
webSocket.CloseAsync()
方法来关闭连接。例如:public async Task HandleWebSocketAsync(HttpContext context, WebSocket webSocket)
{
try
{
// WebSocket连接处理逻辑
}
catch (Exception ex)
{
_logger.Error(ex, "Error occurred while handling WebSocket connection.");
await webSocket.CloseAsync(WebSocketCloseStatus.InternalServerError, "An error occurred while processing the request.", CancellationToken.None);
}
}
通过以上方法,可以有效地处理C# WebSocket服务器中的异常,确保服务器的稳定运行。
