强制用户在Angular 2中按顺序导航

import { Injectable } from '@angular/core';
import { CanActivate, Router } from '@angular/router';

@Injectable()
export class OrderGuard implements CanActivate {
  constructor(private router: Router) {}

  canActivate(): boolean {
    // 检查用户是否已按顺序导航
    if (用户已按顺序导航) {
      return true;
    } else {
      // 如果用户未按顺序导航，则导航到指定页面
      this.router.navigate(['/指定页面']);
      return false;
    }
  }
}

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { OrderGuard } from './order.guard';

const routes: Routes = [
  { path: '页面1', component: 页面1组件 },
  { path: '页面2', component: 页面2组件, canActivate: [OrderGuard] },
  { path: '页面3', component: 页面3组件, canActivate: [OrderGuard] },
  // 其他路由配置...
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule],
  providers: [OrderGuard]
})
export class AppRoutingModule { }
