Angular 路由器无法正确响应浏览器 url

Question

我的问题是，当我在浏览器中更改 url 时，它总是指向起始路线，当我输入路由器中存在的路径以外的其他内容时，我得到 404。

app-routing.module.ts

const routes: Routes = [
  {path: "start", canActivate:[RoutingGuard], component: Start},
  {path: "path-1", canActivate:[RoutingGuard], component: One},
  {path: "path-2", canActivate:[RoutingGuard], component: Two},
  {path: "path-3", canActivate:[RoutingGuard], component: Three},
  {path: "path-4", canActivate:[RoutingGuard], component: Four},
  {path: "", component: Public},
  {path: "**", redirectTo: "", pathMatch:'full'}
];

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

路由-guard.service.ts:

canActivate() {
        this._mysvc.isAuthorized().subscribe(data => this.auth = data);
        if (!this.auth) {
            this._router.navigate(['/']);
        }
        return this.auth;
    }

我有一个登录名，在 Public 组件中我有这个方法，如果用户已登录则重定向到 /start。

public.component.ts:

    isAuthorized(authorized:boolean):void {
        if (authorized) {
          this._router.navigate(['/start']);
        }
      }
  ngOnInit():void {
    this._mysvc.isAuthorized().subscribe(this.isAuthorized.bind(this), this.isAuthorizedError);
  }

index.html:

<html lang="en">
<head>
  <base href="/">

  <!--<meta charset="UTF-8">-->
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
</head>
<body>
  <app-root></app-root>
</body>
</html>

我使用重写配置，所以我跳过了 url

中的#

rewrite.config:

RewriteRule /start/? /index.html [NC]
RewriteRule /path-1/? /index.html [NC]
RewriteRule /path-2/? /index.html [NC]
RewriteRule /path-3/? /index.html [NC]
RewriteRule /path-4/? /index.html [NC]

问题是 async 您处理的请求 sync:

canActivate(): Observable<boolean> {
  return this._mysvc.isAuthorized().do((auth: boolean) => {
     if (!auth) {
       this._router.navigate(['/']);
     }
  });
}

为此，您需要导入 do 运算符：

import 'rxjs/add/operator/do'

或者：

async canActivate(): Promise<boolean> {
  if (!await this._mysvc.isAuthorized().toPromise()) {
     this._router.navigate(['/']);
  }
  return auth;
}

为此，您需要导入 toPromise 运算符

import 'rxjs/add/operator/toPromise';
