angular – 为什么这条路线在直接导航时不匹配？

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：

> Works：在地址栏中输入http：// localhost：9292,正确转发到http：// localhost：9292 / about
> Works：通过地址栏直接导航到http：// localhost：9292 / about
> Works：如果我通过< a>导航到http：// localhost：9292 / about / projects tag,在FrontComponent和[routerLink] =“[‘projects’]”属性的上下文中,路由工作正常.
> Broken：直接导航到http：// localhost：9292 / about / projects会导致以下错误消息(缩短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

我可能在这里做错了什么？有可能有任何方法可以查看错误消息中已拒绝的所有路由吗？

编辑,因为现在已多次建议：我不怀疑这是服务器端问题.以前通过路由器弃用的路由工作正常,从失败路由提供的HTML看起来很好.但为了以防万一,这是相关的服务器端路由代码(与sinatra的ruby)：

# 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(路由确实通过链接工作),但为了完整起见,这些是路由：

前/ front.routes.ts：

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

编辑/ 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)
]
