问题描述

在我的应用程序中重新加载某些路由时出现错误.第一次加载工作正常 http://localhost:8001，所有其他路由从那里工作.但是，如果我在其他路线上重新加载页面，则会在下面出现异常...

例如:

  • http://localhost:8001 有效
  • http://localhost:8001/application 有效
  • http://localhost:8001/application/ 不起作用
  • http://localhost:8001/application/add 不起作用

有人知道为什么会这样吗?

例外:

root.route.ts:

@Component(...)@RouteConfig([{ path: '/', name: 'Root', 组件: DashboardComponent, useAsDefault: true },{ path: '/application/...', name: 'Application', 组件: ApplicationRoute},{ path: '/:unknown', redirectTo: ['/Root'] }])导出类 RootRoute {...}

application.route.ts:

@Component({ 模板:`<p>虚拟模板...</p>` })导出类 Dummy {}@成分(...)@RouteConfig([{ path: '/', name: 'Root', component: Dummy },{ 路径:'/add'，名称:'Add'，组件:Dummy }])导出类 ApplicationRoute 扩展 RouteComponent {...}

更新:

我做了一些调试，结果发现错误是由 TemplateNormalizer，更具体地说是 HtmlParser.parse() 方法.当我从 中删除 标签时，错误消失了.但是没有其他事情发生 - 应用程序没有显示 - 即使 SystemJS 加载了背景...

我还注意到我的一项服务返回了奇怪的结果，原来我使用了相对 URL.这导致我将 <base href="/"> 添加到标题中并解决了所有问题......我不知道为什么，但它接缝 provide(APP_BASE_HREF, { useValue: '/' }) 来自 bootstrap.ts 在某些地方被忽略...

解决方案

另见 Angular 2 路由器没有设置基本的 href

https://angular.io/docs/ts/latest/guide/router.html

<块引用>

在 标签之后添加基本元素.如果 app 文件夹是应用程序根目录，就像我们的应用程序一样，请设置 href 值完全，如下所示.

或者添加

import {provide} from 'angular2/core';从'angular2/router'导入{APP_BASE_HREF}；引导程序(应用程序组件，[ROUTER_PROVIDERS,提供(APP_BASE_HREF，{useValue:'/'})；]);

在您的引导程序中.

I'm getting an error when reloading some of the routes in my app. First load works fine http://localhost:8001, and all other routes work from there. But if I reload page on some other route I get an exception below...

For example:

  • http://localhost:8001 works
  • http://localhost:8001/application works
  • http://localhost:8001/application/ doesn't work
  • http://localhost:8001/application/add doesn't work

Anyone knows why is this happening?

//]]></script>

  <!-- endinject -->
</body>

</html>

UPDATE:

I did some debugging and it turns out errors are generated by TemplateNormalizer, more specifically by HtmlParser.parse() method. When I removed <meta> tags from <head> errors were gone. But nothing else was happening - app didn't show - only <div class="app-loader"> was rendered even though SystemJS loaded all the modules in the background...

I also noticed one of my services was returning weird results, turns out I used relative URL. This lead me to add <base href="/"> to the header and that fixed all the issues... I'm not sure why, but it seams provide(APP_BASE_HREF, { useValue: '/' }) from bootstrap.ts is ignored in some places...

解决方案

See also Angular 2 router no base href set

https://angular.io/docs/ts/latest/guide/router.html

Add the base element just after the <head> tag. If the app folder is the application root, as it is for our application, set the href value exactly as shown here.

<base href="/">

Alternatively add 

import {provide} from 'angular2/core';
import {APP_BASE_HREF} from 'angular2/router';

bootstrap(AppComponent, [
  ROUTER_PROVIDERS, 
  provide(APP_BASE_HREF, {useValue : '/' });
]);

in your bootstrap.
