Angular 2路由在部署到Http服务器时不起作用

Question

我将开发一个简单的Angular 2应用程序。我使用Angular CLI创建了一个带有路由的项目，并使用'ng generate component‘命令向应用程序添加了几个组件。然后我在app-routing.module.ts中指定路由，如下所示。

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { AboutComponent } from './about/about.component';
import { UserComponent } from './user/user.component';
import { ErrorComponent } from './error/error.component';
import { SpecialpageComponent } from './specialpage/specialpage.component';

const routes: Routes = [
  {
    path: '',
    component: HomeComponent
  },
  {
    path: 'about',
    component: AboutComponent
  },
    {
    path: 'user',
    component: UserComponent
  },
  {
    path: 'specialpage',
    component: SpecialpageComponent
  },
  {
    path: '**',
    component: ErrorComponent
  }

];

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

app.module.ts如下所示。

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { AppRoutingModule } from './app-routing.module';

import { AppComponent } from './app.component';
import { HomeComponent } from './home/home.component';
import { AboutComponent } from './about/about.component';
import { ErrorComponent } from './error/error.component';
import { UserComponent } from './user/user.component';
import { SpecialpageComponent } from './specialpage/specialpage.component';

@NgModule({
  declarations: [
    AppComponent,
    HomeComponent,
    AboutComponent,
    ErrorComponent,
    UserComponent,
    SpecialpageComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    AppRoutingModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

我没有为其他组件添加任何修改。然后，我使用'ng serve'命令部署了应用程序，应用程序可以很好地处理链接。例如：http://localhost:4200/关于

如有任何帮助，我们将不胜感激。提前道谢。

我已经把我的项目上传到了GitHub。

通过实现HashLocationStrategy来解决这个问题，它将#添加到所有路由。您可以通过向AppModule Providers添加HashLocationStrategy来实现这一点。

    providers: [{provide: LocationStrategy, useClass: HashLocationStrategy}],

并添加相应的导入

   import { HashLocationStrategy, LocationStrategy } from '@angular/common';

这会解决你的问题。
