angular打包后路由和文件路径不对

base href换成如下script标签

  <!-- <base href="/"> -->
  <script>
    document.write('<base href="' + document.location + '" />');
  </script>

在app.module.ts下添加 { provide: LocationStrategy, useClass: HashLocationStrategy }

providers: [
    HttpErrorHandler,
    httpInterceptorProviders,
    CookieService,
    { provide: NZ_I18N, useValue: zh_CN },
    { provide: RequestCache, useClass: RequestCacheWithMap },
    { provide: RouteReuseStrategy, useClass: CustomReuseStrategy },
    { provide: LocationStrategy, useClass: HashLocationStrategy }
  ]

搞定！
