基于保护的同一路径上的延迟加载模块

Question

我想基于同一（“”）路径（home）上的用户角色加载特定的角度模块。比方说，我有两个名为AdminModule和OperatorModule的模块。如果角色是ADMIN，那么我想加载AdminModule，否则加载OperatorModule。我想用Angular Guard归档这个。

现在在app.routing.ts我添加了以下代码：

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

import { AuthGuard } from './core/guards/auth.guard';

import { AdminModule } from './modules/admin';
import { OperatorModule } from './modules/operator';

const routes: Routes = [
   {
      path: '',
      loadChildren: () => AdminModule,
      canLoad: [ AuthGuard ],
      data: { role: 'ADMIN' }
   },

   {
      path: '',
      loadChildren: () => OperatorModule,
      canLoad: [ AuthGuard ],
      data: { role: 'OPERATOR' }
   },
];

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

我已经使用以下代码实现了AngularGuard，它必须显示OperatorModule：

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

@Injectable({
   providedIn: 'root'
})
export class AuthGuard implements CanLoad {
   constructor(private router: Router) {}

   canLoad(route: Route): Promise<boolean> | boolean {
      if (route.data.role === 'OPERATOR') {
         return true;
      }

      return false;
   }
}

不知怎的，它停止照顾第一条路线失败，我做错了什么？

Matcher也不起作用：

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

import { AuthGuard } from './core/guards/auth.guard';

import { AdminModule } from './modules/admin';
import { OperatorModule } from './modules/operator';

const routes: Routes = [
   {
      loadChildren: () => AdminModule,
      matcher: AdminMatcher,
      data: { role: 'NO' }
   },

   {
      loadChildren: () => OperatorModule,
      matcher: OperatorMatcher,
      data: { role: 'OPERATOR' }
   },
];

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

   }
}


import { UrlSegment, UrlSegmentGroup, Route } from '@angular/router';
export function AdminMatcher(segments: UrlSegment[], group: UrlSegmentGroup, route: Route) {
   const isPathMatch = segments[0].path === route.path;

   if (isPathMatch && route.data.role === 'ADMIN') {
      return { consumed: [segments[0]] };
   } else {
      return null;
   }
}

export function OperatorMatcher(segments: UrlSegment[], group: UrlSegmentGroup, route: Route) {
   const isPathMatch = segments[0].path === route.path;

   if (isPathMatch && route.data.role === 'OPERATOR') {
      return { consumed: [segments[0]] };
   } else {
      return null;
   }
}

最好是使用UrlMatchers代替canLoad，根据你的条件匹配每一个，当2路径中的一个匹配时，另一个路径将自动被忽略

 const routes: Routes = [{
  path: '',
  matcher: adminMatcher,
  oadChildren: () => AdminModule,
  data: { role: 'ADMIN' }
 },
 {
  path: '',
  matcher: operatormatcher,
  loadChildren: () => OperatorModule,
  data: { role: 'OPERATOR' }

 }]
