Question

我在刷新浏览器时遇到问题，显示404找不到错误。

我试过添加
在index.html但它没用。并且 LocationStrategy，HashLocationStrategy 但似乎行不通。

我正在使用带有4.5 .net框架的VS2015

这是我的app.routes.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

import { JobBookingComponent } from './component/jobbooking';
import { JobDetailsComponent } from './component/jobbookingdetailscomponent';
import { JPTemplateComponent } from './component/jptemplate.component';


const routes: Routes = [
{ path: '', redirectTo: '/templatejp', pathMatch: 'full' },

{ path: 'template', component: JobBookingComponent },
{ path: 'templatejp', component: JPTemplateComponent },
{ path: 'detail/:templateid', component: JobDetailsComponent }

];

@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { }

的index.html

<html>
<head>
<script>document.write('<base href="/" />');</script>
<title>Demo</title>
 <meta charset="UTF-8">
 <meta name="viewport" content="width=device-width, initial-scale=1">

</script>
</head>
<!-- 3. Display the application -->

</html>

app.ts

import './rxjs-operator';
import { Component, ViewContainerRef } from '@angular/core';

@Component({
selector: 'my-app',
template: `
<nav>
<a routerLink="/template" routerLinkActive= "active" > Template </a>
  <a routerLink="/templatejp" routerLinkActive= "active" > Templatejp </a>
    </nav>
 <router-outlet></router-outlet>`
 })

 export class AppComponent {

  }

请帮助解决问题感谢。

好的问题是我导入的PathLocationStrategy需要使用HashLocationStrategy 更新（app.module.ts）通过导入HashLocationStrategy和locationstrategy并添加提供程序。

import { NgModule }       from '@angular/core';
import { BrowserModule  } from '@angular/platform-browser';
import { AppComponent }   from './app.component';
import { HashLocationStrategy, LocationStrategy } from '@angular/common';

@NgModule({
declarations: [AppComponent],
imports: [BrowserModule],
providers: [{provide: LocationStrategy, useClass: HashLocationStrategy}],
bootstrap: [AppComponent],
})
export class AppModule {}

Answer 2

在索引页面上添加<base href="/" />，而不是从脚本

动态添加它

Answer 3

因此，404错误意味着您的Web服务器（在本例中是您在构建应用程序时运行的开发服务器）无法找到该页面。您的应用程序是否构建没有任何错运行控制台时，应显示所请求页面的日志以及是否找到它们（http状态200）。

问题正在发生，因为无法找到路线，请使用来自＆＃39; @ angular / core＆＃39 ;;的导入{ModuleWithProviders};以下是路由导出的示例代码：

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

import { JobBookingComponent } from './component/jobbooking';
import { JobDetailsComponent } from './component/jobbookingdetailscomponent';
import { JPTemplateComponent } from './component/jptemplate.component';


const routes: Routes = [
{ path: '', redirectTo: 'templatejp', pathMatch: 'full' },

{ path: 'template', component: JobBookingComponent },
{ path: 'templatejp', component: JPTemplateComponent },
{ path: 'detail/:templateid', component: JobDetailsComponent }

];

@NgModule({
export const routing: ModuleWithProviders = RouterModule.forRoot(appRoutes, { useHash: true });
})
export class AppRoutingModule { }
