通过实现接口IExceptionFilter

Global文件添加GlobalFilters.Filters.Add(new ExExceptionFilter());

 public class ExExceptionFilter : IExceptionFilter { private static ILog log = LogManager.GetLogger(typeof(ExExceptionFilter)); public void OnException(ExceptionContext filterContext) { log.Error("出现未处理异常", filterContext.Exception); HttpRequestBase request = filterContext.RequestContext.HttpContext.Request; if (request.Headers.AllKeys.Contains("X-Requested-With") && request.Headers["X-Requested-With"].Equals("XMLHttpRequest")) { AjaxResult ajaxResult = new AjaxResult(0, "发生错误"); ajaxResult.data.Add("Exception", filterContext.Exception.Message); ajaxResult.data.Add("detail", filterContext.Exception.ToString()); filterContext.Result = new JsonResult() { Data = ajaxResult }; } else { filterContext.Result = new RedirectResult("/Manager/Manager/Error"); } filterContext.ExceptionHandled = true; filterContext.HttpContext.Response.Clear(); //filterContext.HttpContext.Response.StatusCode = 500; filterContext.HttpContext.Response.TrySkipIisCustomErrors = true; } }
