ERROR Error: Uncaught (in promise), Cannot match any routes. URL Segment

Question

我在 angular 6 个应用中有简单的导航，

这里是HTML

<nav class="main-nav>
<ul class="main-nav__list " ng-sticky [addClass]="'main-sticky-link'" [ngClass]="ref.click === true? 'Navbar__ToggleShow' :''">
            <li class="main-nav__item">
              <a class="main-nav__link" routerLink="['/']" routerLinkActive="active">Home</a>
            </li>
            <li class="main-nav__item"> 
              <a class="main-nav__link" routerLink="['/about']" routerLinkActive="active">About us</a>
            </li>

          </ul>
</nav>

这里是app.routing模块

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { MainLayoutComponent } from './layout/main-layout/main-layout.component';
import { AboutComponent } from './components/about/about.component';
import { WhatwedoComponent } from './components/whatwedo/whatwedo.component';
import { FooterComponent } from './components/footer/footer.component';
import { ProjectsComponent } from './components/projects/projects.component';
const routes: Routes = [
  { path: 'about', component: AboutComponent },
  { path: 'what', component: WhatwedoComponent },
  { path: 'contacts', component: FooterComponent },
  { path: 'projects', component: ProjectsComponent},
];

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

这是应用模块

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { NgStickyDirective } from 'ng-sticky';
import { RouterModule } from '@angular/router';
import { AppComponent } from './app.component';
import { MainLayoutComponent } from './layout/main-layout/main-layout.component';
import { AppRoutingModule } from './/app-routing.module';
import { MainNavDirective } from './layout/main-nav.directive';
import { AboutComponent } from './components/about/about.component';
import { WhatwedoComponent } from './components/whatwedo/whatwedo.component';
import { FooterComponent } from './components/footer/footer.component';
import { WhyChooseUsComponent } from './components/why-choose-us/why-choose-us.component';
import { TeamComponent } from './components/team/team.component';
import { ProjectsComponent } from './components/projects/projects.component';
import { ClientsComponent } from './components/clients/clients.component';
import { HowItWorksComponent } from './components/how-it-works/how-it-works.component';
import { PartnersComponent } from './components/partners/partners.component';

@NgModule({
  declarations: [
    AppComponent,
    NgStickyDirective,
    MainLayoutComponent,
    MainNavDirective,
    AboutComponent,
    WhatwedoComponent,
    FooterComponent,
    WhyChooseUsComponent,
    TeamComponent,
    ProjectsComponent,
    ClientsComponent,
    HowItWorksComponent,
    PartnersComponent
  ],
  imports: [
    BrowserModule,
    RouterModule,
    AppRoutingModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

当我运行我的应用程序并点击关于我们时，我收到以下错误：

core.js:1673 ERROR Error: Uncaught (in promise): Error: Cannot match any routes. URL Segment: '%5B'/about'%5D'
Error: Cannot match any routes. URL Segment: '%5B'/about'%5D'
    at

我已经尝试了不同的组合来解决这个问题，但仍然无法摆脱这个错误，

我的代码哪里做错了？任何帮助都会有帮助谢谢

Answer 1

当你这样使用routerLink时，你需要传递它应该去的路由的值。但是当你使用带有属性绑定语法的 routerLink 时，像这样：[routerLink]，那么它应该被分配一个属性的名称，其值将是它应该导航的路由用户到。

因此，要解决您的问题，请将 HTML 中的 routerLink="['/about']" 替换为 routerLink="/about"。

在其他地方，您在并非真正需要时使用了属性绑定语法。我已经修复了它，您可以简单地使用下面的模板语法：

<nav class="main-nav>
  <ul 
    class="main-nav__list" 
    ng-sticky 
    addClass="main-sticky-link" 
    [ngClass]="ref.click ? 'Navbar__ToggleShow' : ''">
    <li class="main-nav__item" routerLinkActive="active">
      <a class="main-nav__link" routerLink="/">Home</a>
    </li>
    <li class="main-nav__item" routerLinkActive="active"> 
      <a class="main-nav__link" routerLink="/about">About us</a>
    </li>
  </ul>
</nav>

它还需要知道应该在哪里加载与它到达的路由对应的组件的模板。因此，不要忘记在上面提供的模板或父组件中添加 <router-outlet></router-outlet>。

您的 AppRoutingModule 还有一个问题。您需要从那里导出 RouterModule，以便您的 AppModule 在导入时可以使用它。要解决此问题，请通过将其添加到 exports 数组来将其从 AppRoutingModule 中导出。

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { MainLayoutComponent } from './layout/main-layout/main-layout.component';
import { AboutComponent } from './components/about/about.component';
import { WhatwedoComponent } from './components/whatwedo/whatwedo.component';
import { FooterComponent } from './components/footer/footer.component';
import { ProjectsComponent } from './components/projects/projects.component';
const routes: Routes = [
  { path: 'about', component: AboutComponent },
  { path: 'what', component: WhatwedoComponent },
  { path: 'contacts', component: FooterComponent },
  { path: 'projects', component: ProjectsComponent},
];

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

Answer 2

如错误所述，您的路由器 link 应与配置的现有路由相匹配

应该只是 routerLink="/about"

Answer 3

如果您需要 [] 语法，当您需要传递 id[=25= 等参数时，可用于“edit forms” ] 路线，你会做这样的事情：

[routerLink]="['edit', business._id]"

至于没有像您这样的参数的“关于页面”，

[routerLink]="/about"

或

[routerLink]=['about']

会成功的。

Answer 4

我找了很多天找到了正确答案；只需转换 routerLink="['/jkh',id]"

至

[routerLink]="['/jkh',id]"

并给出所有的要求和它的解决方案 ;
