angular - 动态路由被添加到路由器但不起作用

问题描述

我在 Angular 6 中创建了一个应用程序，登录后将用户带到主页。toolbar此页面在顶部的导航栏（称为）和左侧的侧栏（称为 ）上包含多个链接side-nav。我创建了一个自定义动态路由服务，它将为 html 模板添加链接及其标签。

使用 将路径添加到路由器，并且当我在控制台中登录路由器时router.config.unshift，我已验证这些路径已正确添加。config

我的应用程序的登录页面有根路径（即' '），Main登录后的页面有路径/main（下面添加了路由器配置）。

我似乎遇到的问题有两个部分：

  1. 每当我单击side-nav或 上toolbar的链接时，地址栏上的 url 都会显示给我localhost.com:4200/main/<path>，而显示的页面是NotFoundComponent（即找不到路线）。我不希望路径是child根/mainurl (ie ' ')，因为导航栏会在每个页面上，这可能会导致localhost:4200/main/<path>/<anotherpath>/<someotherpath>/<path>单击多个项目的情况，这是一个非常糟糕的设计。

  2. 如果我尝试手动添加应用程序的路径，例如。localhost:4200/<path>显示相同的结果（NotFoundComponent）。无论我做什么，它都找不到路径，即使在控制台中它在我登录路由器时已经完美定义。

出于测试目的，我的所有路径都将我重定向到DummyComponent.

这是我的代码，我正在分享我的代码，ToolbarComponent除了一些点点滴滴，Side Nav 几乎相同：

app.routing.ts：

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


import { LoginComponent } from 'src/app/views/login/login.component';
import { MainComponent } from 'src/app/views/main/main.component';
import { AuthGuardService } from 'src/app/services/auth-guard/auth-guard.service';
import { NotFoundComponent } from 'src/app/views/error/not-found/not-found.component';
/**
* Contains a list of routes to enable navigation from one view to the next
* as users perform application tasks
* @property {array} routes
*/
export const routes: Routes = [
  {
    path: '',
    component: LoginComponent,
  },
  {
    path: 'main',
    component: MainComponent,
    canActivate: [AuthGuardService]
  },
  {
    path: '**',
    component: NotFoundComponent
  }
];

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

动态路由.service.ts

import { Injectable } from '@angular/core';
import { TranslatePipe } from 'src/app/pipes/translate/translate.pipe';

@Injectable({
  providedIn: 'root'
})
/*
* This service will provide components with the ability to dynamically create
* routes within the application
*/
export class DynamicRoutingService {

  /*
  * Array for storing links
  *
  */
  private links = new Array<{ text: string, path: string, icon: string }>();

  constructor(private translate: TranslatePipe) { }

  /*
  * Method to fetch data
  *
  */
  getLinks() {
    if (this.links.length != 0) {
      return this.links;
    }
    else {
      throw new Error(this.translate.transform("generic[responses][error][404][002]"));
    }
  }

  /*
  * Method to store data
  *
  */
  addItem({ text, path, icon = null }) {
    try {
      this.links.push({ text: text, path: path, icon: icon });
    } catch (e) {
      throw new Error(this.translate.transform("generic[responses][error][400]"));
    }
  }

  /*
  * Method to remove a specific link
  *
  */
  removeItem({ text }) {
    if (this.links.length != 0) {
      this.links.forEach((link, index) => {
        if (link.text === text) {
          this.links.splice(index, 1);
        }
      });
    } else {
      throw new Error (this.translate.transform('generic[resposnes][error][404][002]'));
    }
  }

  /*
  * Remove all links from the array
  */
  clearAll() {
    this.links.length = 0;
  }
}
