Question

当用户输入的网址与我的网络应用中的任何路径不匹配时，我设置了“404页面未找到”页面：

export const routerConfig: Routes = [
   {
      component: LandingPageComponent,
      path: "",
   },
   {
      component: ProfilePageComponent,
      path: "profile",
   },
   {
      component: NotFoundPageComponent,
      path: "**",
   },
];

但是当我输入我的应用地址然后输入错误的路径（例如http://localhost:3000/prcds）时，它只会显示：

Cannot GET /prcds

在控制台出错的空白网页中：

无法加载资源：服务器响应状态为404 （未找到）

我已将NotFoundPageModule添加到app.module个导入中。

我使用了https://angular.io/docs/ts/latest/guide/router.html中的“配置”部分，并复制了他们如何在我的项目中设置404未找到的页面。

如何让它停止显示该错误并显示我为404错误制作的实际页面？

它显示了我的其他问题中的相同页面，因此它与this issue相关的可能性很小：

我的代码：

找不到页面文件结构：

notfoundpage.component.ts

import { Component } from "@angular/core";
import { Title } from "@angular/platform-browser";

@Component({
   selector: "not-found-page",

   templateUrl: "dist/app/components/not-found-page/not-found-page.component.html",

使用以下代码替换app.routes.ts文件：

＆＃13;

import { Routes, RouterModule } from "@angular/router";
import { AboutPageComponent } from "./components/about-page/about-page.component";
import { AddPageComponent } from "./components/add-page/add-page.component";
import { FindPageComponent } from "./components/find-page/find-page.component";
import { LandingPageComponent } from "./components/landing-page/landing-page.component";
import { NotFoundPageComponent } from "./components/not-found-page/not-found-page.component";
import { ProfilePageComponent } from "./components/profile-page/profile-page.component";
import { RegisterPageComponent } from "./components/register-page/register-page.component";

const routerConfig: Routes = [
   {
      component: LandingPageComponent,
      path: "",
   },
   {
      component: FindPageComponent,
      path: "find",
   },
   {
      component: AddPageComponent,
      path: "add",
   },
   {
      component: RegisterPageComponent,
      path: "register",
   },
   {
      component: AboutPageComponent,
      path: "about",
   },
   {
      component: ProfilePageComponent,
      path: "profile",
   },
   {
      component: NotFoundPageComponent,
      path: "404",
   },
   {
      path: "**",
      redirectTo: '404' 
   }
];

export const routerConfig = RouterModule.forRoot(routerConfig);

您需要提供pathMatch：'full'，如下所示：

        export const routerConfig: Routes = [
           {
              component: LandingPageComponent,
              path: "",
           },
           {
              component: ProfilePageComponent,
              path: "profile",
           },
            { path: '', redirectTo: 'NotFoundPageComponent', pathMatch: 'full' },
           {
              component: NotFoundPageComponent,
              path: "**",
           },
        ];

在“notfoundpage.module.ts”中，请尝试以下操作：

替换它：

       import * as NotFoundPage from "./index";

有了这个：

        import {NotFoundPageComponent } from './not-found-page.component';

并替换它：

     declarations: [
          NotFoundPage.NotFoundPageComponent,
       ],
       exports: [NotFoundPage.NotFoundPageComponent]

有了这个：

         declarations: [
              NotFoundPageComponent,
           ],
           exports: [NotFoundPageComponent]
