为什么直接导航到这条路线时不匹配？

Question

声明：这里使用的是当前相当新的"@angular/router": "3.0.0-alpha.8"，路由定义在帖子底部。

尝试在我的应用程序中导航时，行为会有所不同，具体取决于我是直接输入 URL 还是跟随链接：

• 作品：在地址栏中输入http://localhost:9292，正确转发到http://localhost:9292/about
• 工作：通过地址栏直接导航到http://localhost:9292/about
• 有效：如果我通过<a> 标记导航到http://localhost:9292/about/projects，在FrontComponent 和[routerLink]="['projects']" 属性的上下文中，路由工作正常。

• 损坏：直接导航到 http://localhost:9292/about/projects 会导致以下错误消息（缩短的 Stacktrace）：

  Unhandled Promise rejection: Cannot match any routes: 'projects' ; Zone: angular ; Task: Promise.then ; Value: Error: Cannot match any routes: 'projects'
  Stack trace:
  applyRedirects/<@http://localhost:9292/node_modules/@angular/router/apply_redirects.js:29:34
  Observable.prototype.subscribe@http://localhost:9292/node_modules/rxjs/Observable.js:52:57
  

我在这里可能做错了什么？有没有办法查看错误消息中所有被拒绝的路由？

编辑，因为这已被多次建议：我不怀疑这是服务器端问题。先前通过router-deprecated 的路由工作正常，而从失败路由提供的HTML 看起来也很好。但以防万一，这是相关的服务器端路由代码（ruby 和 sinatra）：

# By now I have too often mistakenly attempted to load other assets than
# HTML files from "user facing" URLs, mostly due to paths that should have
# been absolute but weren't. This route attempts to catch all these
# mistakes rather early, so that the show up as a nice 404 error in the
# browsers debugging tools
get /^\/(about|editor)\/.*\.(css|js)/ do
  halt 404, "There are no assets in `editor` or `about` routes"
end

# Matching the meaningful routes the client knows. This enables navigation
# even if the user submits a "deep link" to somewhere inside the
# application.
index_path = File.expand_path('index.html', settings.public_folder)
get '/', '/about/?*', '/editor/*' do
  send_file index_path
end

# Catchall for everything that goes wrong
get '/*' do
  halt 404, "Not found"
end

我不怀疑这是由于错误的路由定义（路由确实通过链接起作用），但为了完整起见，这些是路由：

front/front.routes.ts：

export const FrontRoutes : RouterConfig = [
    {
        path: '',
        redirectTo: '/about',
        terminal: true
    },
    {
        path : 'about',
        component: FrontComponent,
        children : [
            { path: 'projects', component: ProjectListComponent},
            { path: '',         component: AboutComponent},
        ]
    }
]

editor/editor.routes.ts：

export const EditorRoutes : RouterConfig = [
    {
        path: "editor/:projectId",
        component : EditorComponent,
        children : [
            { path: '', redirectTo: 'settings', terminal: true},
            { path: 'settings', component : SettingsComponent },
            { path: 'schema', component : SchemaComponent },
            { path: 'query/create', component : QueryCreateComponent },
            { path: 'query/:queryId', component : QueryEditorComponent },
            { path: 'page/:pageId', component : PageEditorComponent },
        ]
    }
]

app.routes.ts：

import {EditorRoutes}                   from './editor/editor.routes'
import {FrontRoutes}                    from './front/front.routes'

export const routes : RouterConfig = [
    ...FrontRoutes,
    ...EditorRoutes,
]

export const APP_ROUTER_PROVIDERS = [
    provideRouter(routes)
]

将"/" 设置为base 标记的值index.html 以使路由器正确解析子路径。这是not in line with the offical docs，但似乎有效。
