C# 全局异常过滤器

1、定义一个类 使其继承 IExceptionFilter 接口

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

public class MyExceptionFilter : IExceptionFilter {     public MyExceptionFilter(ILogger<MyExceptionFilter> logger)     {         Logger = logger;     }       public ILogger<MyExceptionFilter> Logger { get; }       public void OnException(ExceptionContext context)     {         if (!context.ExceptionHandled)         {             Logger.LogInformation($"全局异常过滤器:{context.Exception.Message}");             context.Result = new ContentResult             {                 Content = "服务器异常，请稍后再试。。"             };         }         context.ExceptionHandled = true;     } }

2、在program　中配置

builder.Services.AddControllers(x =>
{
    x.Filters.Add<MyExceptionFilter>();
});
