在使用Asp.Net Core Mvc时 404处理整理以下html
1、自带404状态处理post
1.控制器视图子弹404视图 NotFoundResult,NotFoundObjectResult网站
// // 摘要: // Creates an Microsoft.AspNetCore.Mvc.NotFoundObjectResult that produces a Microsoft.AspNetCore.Http.StatusCodes.Status404NotFound // response. // // 返回结果: // The created Microsoft.AspNetCore.Mvc.NotFoundObjectResult for the response. [NonAction] public virtual NotFoundObjectResult NotFound(object value); // // 摘要: // Creates an Microsoft.AspNetCore.Mvc.NotFoundResult that produces a Microsoft.AspNetCore.Http.StatusCodes.Status404NotFound // response. // // 返回结果: // The created Microsoft.AspNetCore.Mvc.NotFoundResult for the response. [NonAction] public virtual NotFoundResult NotFound();
2.当前操做返回404状态,或者返回404的一句话提示。url
2、自定义404页面显示spa
在网站中,为了加强提早,一般使用自定义404页面code
1.自定义404视图,在控制器中返回htm
/// <summary> /// 定义404视图 /// </summary> public class NotFoundViewResult : ViewResult { public NotFoundViewResult(string viewName) { ViewName = viewName; StatusCode = (int)HttpStatusCode.NotFound; } }
2.在控制器中返回使用blog
public IActionResult Index() { //返回404页面 return new NotFoundViewResult("~/views/Error/code_404.cshtml"); return View(); }
3.呈现结果:get
