MVC异常日志生产者消费者模式记录（异常过滤器）

生产者消费者模式

定义自己的异常过滤器并注册

namespace Eco.Web.App.Models
{
    public class MyExceptionAttribute : HandleErrorAttribute
    {
        public static Queue<Exception> ExceptionQueue = new Queue<Exception>();
        public override void OnException(ExceptionContext filterContext)
        {
            base.OnException(filterContext);
            ExceptionQueue.Enqueue(filterContext.Exception);//将异常信息添加到队列中。
            filterContext.HttpContext.Response.Redirect("/Error.html");

        }
    }
}

namespace Eco.Web.App
{
    public class FilterConfig
    {
        public static void RegisterGlobalFilters(GlobalFilterCollection filters)
        {
            filters.Add(new MyExceptionAttribute());
        }
    }
}
