详解Angular4 路由设置相关

/*路由基本模型*//*导入RouterModule，Routes类型*/import { RouterModule, Routes } from '@angular/router';import { LoginComponent } from "./login/login.component";/*定义路由const表示不可改变*/const routers: Routes = [ /*  path：字符串，表示默认登入,  path为路径 /login component:组件  component：组件  pathMatch：为字符串默认为前缀匹配 "prefix"; "full" 为完全匹配。  redirectTo：指向为路径，既path  outlet：字符串，路由目标，面对多个路由的情况  children：Routes 子路由相关  */ { path: '', component: LoginComponent }, // path:路径 /detail/1 :id代表参数相关 { path: 'detail/:id', component: LoginComponent }, // 懒加载子模块, 子模块需要配置路由设置启动子组件，如果这样设置了路由，需要在子模块中再定义路由 { path: 'other', loadChildren:"./demo/demo.module#demoModule" }, // 重定向，路径为** 表示不能识别的路径信息，重定向到相关路径下 { path: '**', pathMatch: 'full', redirectTo: '' }];/*将路由设置导出,子模块中的路由使用 forChild 而不是 forRoot*/export const appRouter = RouterModule.forRoot(routers);

@NgModule({ declarations: [ ...... ], imports: [ ......  appRouter ]})

<router-outlet></router-outlet>

{ path: 'news', outlet: 'let1', component: NewsComponent },{ path: 'news', outlet: 'let2', component: News2Cmponent },//模板中<router-outlet name="let1"></router-outlet><router-outlet name="let2"></router-outlet>

<a routerLink="/detail/1" routerLinkActive="active">detail</a><a [routerLink]="['/detail', news.id]">{{news.title}}</a><a [routerLink]="[{ outlets: { let2: ['news'] } }]">Contact</a>

this.router.navigate(['/detail', this.news.id])this.router.navigate([{ outlets: { let2: null }}]);

import { Injectable }   from '@angular/core';import { CanActivate }  from '@angular/router';@Injectable()export class AuthService implements CanActivate { canActivate() {  // 这里判断登录状态, 返回 true 或 false  return true; }}

import { Injectable }   from '@angular/core';import { CanDeactivate, ActivatedRouteSnapshot, RouterStateSnapshot }  from '@angular/router';// CanDeactivateComponent 是定义的接口,见下段代码import { CanDeactivateComponent } from './can-deactivate.omponent';@Injectable()export class DeacService implements CanDeactivate<CanDeactivateComponent> { canDeactivate(  canDeactivateComponent: CanDeactivateComponent,  activatedRouteSnapshot: ActivatedRouteSnapshot,  routerStateSnapshot: RouterStateSnapshot ) {  // 目标路由和当前路由  console.log(activatedRouteSnapshot);  console.log(routerStateSnapshot);  // 判断并返回  return canDeactivateComponent.canDeactivate ? canDeactivateComponent.canDeactivate() : true }}

// 接口组件, 返回 true 或 false 如表单发生改变则调用对话框服务export interface CanDeactivateComponent { canDeactivate: () => Observable<boolean> | Promise<boolean> | boolean;}
