Error: Cannot match any routes. URL Segment: 'admin/projects/projectssCategory/list'

Question

对于一个和另一个模块，我反复收到此错误。

ListProjectCategoryRoutingModule

看起来像：

import { NgModule } from '@angular/core';
import { AuthGuard } from '../../../../../helpers/auth.gaurd';
import { Role } from '../../../../../data/schema/role';
import { Routes, RouterModule } from '@angular/router';

import { ListProjectCategoryComponent } from './list-project-category.component';

const routes: Routes = [{ path: 'admin/projects/projectCategory/list', 
component: ListProjectCategoryComponent 
//canActivate: [AuthGuard],
//data: { roles: [Role.Admin]}
}];

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


ListProjectCategoryComponent

看起来像：

import { DetailsProjectCategoryComponent } from '../details-project-category/details-project-category.component';
import { Observable } from "rxjs";
import { ProjectsCategoryService } from "../../../../../data/service/projectsCategory.service";
import { ProjectsCategory } from "../../../../../data/schema/projects";
import { Component, OnInit } from "@angular/core";
import { Router } from '@angular/router';

@Component({
  selector: "app-list-project-category",
  templateUrl: "./list-project-category.component.html",
  styleUrls: ["./list-project-category.component.css"]
})
export class ListProjectCategoryComponent implements OnInit {
  projectsCategory: Observable<ProjectsCategory[]>;

  constructor(private projectsCategoryService: ProjectsCategoryService,
    private router: Router) {}

  ngOnInit() {
    this.reloadData();
  }

  reloadData() {
    this.projectsCategory = this.projectsCategoryService.getProjectsCategorysList();
  }

  deleteProjectsCategory(id: number) {
    this.projectsCategoryService.deleteProjectsCategory(id)
      .subscribe(
        data => {
          console.log(data);
          this.reloadData();
        },
        error => console.log(error));
  }

  // employeeDetails(id: number){
  //   this.router.navigate(['details', id]);
  //}
}

我从 html 文件调用它，Home、Admin、Projects 页面导航正确，但我在 ProjectCategory 页面中遇到错误

<div *ngIf="isAdmin">
<nav class="navbar navbar-expand navbar-dark bg-dark" *ngIf="user">
    <div class="navbar-nav">
        <a class="nav-item nav-link" routerLink="/admin/home">Home</a>
        <a class="nav-item nav-link" routerLink="/admin" *ngIf="isAdmin">Admin</a>
        <a class="nav-item nav-link" routerLink="/admin/projects">Projects</a>
        <a class="nav-item nav-link" routerLink="/admin/projects/projectssCategory/list">List Project Category</a>
        <a class="nav-item nav-link" (click)="logout()">Logout</a>
    </div>
</nav>
</div>

我必须添加更多类似于 ListProjectCategory

的模块

已在 app.routing.ts 中添加了他们的路线，并且它对其他模块工作正常

{ path: '', loadChildren: () => import('./modules/admin/project-folder/projectCategory/list-project-category/list-project-category.module').then(m => m.ListProjectCategoryModule) },

Answer 1

你有路径

routerLink="/admin/projects/projectssCategory/list"

但路线预期

admin/projects/projectCategory/list

只需合并预期结果和实际结果

我认为 projectssCategory 有问题，其中双 s

Answer 2

在应用路由中。在作为路由的模块架构中，您应该提供基本路径，例如 admin。如果你有第二个模块，那么你可能会遇到空基本路线的问题。

{ path: 'admin', loadChildren: () => import('./modules/admin/project-folder/projectCategory/list-project-category/list-project-category.module').then(m => m.ListProjectCategoryModule) }

在路由模块中

const routes: Routes = [{ path: 'projects/projectCategory/list', 
component: ListProjectCategoryComponent 
//canActivate: [AuthGuard],
//data: { roles: [Role.Admin]}
}];

并确保 link 您提供的

是正确的

在html中调用/admin/projects/projectCategory/list在routerLink

中

Error: Cannot match any routes. URL Segment: 'admin/projects/projectssCategory/list'

Error: Cannot match any routes. URL Segment: 'admin/projects/projectssCategory/list'
