简单配置link

Simple Configurationlink

The following route specifies that when navigating to, for example, /team/11/user/bob, the router creates the 'Team' component with the 'User' child component in it.

      
        content_copy
      
      [{
  path: 'team/:id',
 component: Team,
  children: [{
    path: 'user/:name',
    component: User
  }]
}]
    

Multiple Outletslink

The following route creates sibling components with multiple outlets. When navigating to /team/11(aux:chat/jim), the router creates the 'Team' component next to the 'Chat' component. The 'Chat' component is placed into the 'aux' outlet.

      
        content_copy
      
      [{
  path: 'team/:id',
  component: Team
}, {
  path: 'chat/:user',
  component: Chat
  outlet: 'aux'
}]
    

Wild Cardslink

The following route uses wild-card notation to specify a component that is always instantiated regardless of where you navigate to.

      
        content_copy
      
      [{
  path: '**',
  component: WildcardComponent
}]
    

Redirectslink

The following route uses the redirectTo property to ignore a segment of a given URL when looking for a child path.

When navigating to '/team/11/legacy/user/jim', the router changes the URL segment '/team/11/legacy/user/jim' to '/team/11/user/jim', and then instantiates the Team component with the User child component in it.

      
        content_copy
      
      [{
  path: 'team/:id',
  component: Team,
  children: [{
    path: 'legacy/user/:name',
    redirectTo: 'user/:name'
  }, {
    path: 'user/:name',
    component: User
  }]
}]
    

The redirect path can be relative, as shown in this example, or absolute. If we change the redirectTo value in the example to the absolute URL segment '/user/:name', the result URL is also absolute, '/user/jim'.

空路径link

Empty Pathlink

空路径路由可用来实例化一些不"消费"任何 url 区段的组件。

Empty-path route configurations can be used to instantiate components that do not 'consume' any URL segments.

在下列配置中，当导航到 /team/11 时，路由器会实例化 'AllUsers' 组件。

In the following configuration, when navigating to /team/11, the router instantiates the 'AllUsers' component.

      
        content_copy
      
      [{
  path: 'team/:id',
  component: Team,
  children: [{
    path: '',
    component: AllUsers
  }, {
    path: 'user/:name',
    component: User
  }]
}]
    

Empty-path routes can have children. In the following example, when navigating to /team/11/user/jim, the router instantiates the wrapper component with the user component in it.

Note that an empty path route inherits its parent's parameters and data.

      
        content_copy
      
      [{
  path: 'team/:id',
  component: Team,
  children: [{
    path: '',
    component: WrapperCmp,
    children: [{
      path: 'user/:name',
      component: User
    }]
  }]
}]
    

Matching Strategylink

The default path-match strategy is 'prefix', which means that the router checks URL elements from the left to see if the URL matches a specified path. For example, '/team/11/user' matches 'team/:id'.

      
        content_copy
      
      [{
  path: '',
  pathMatch: 'prefix', //default
  redirectTo: 'main'
}, {
  path: 'main',
  component: Main
}]
    

You can specify the path-match strategy 'full' to make sure that the path covers the whole unconsumed URL. It is important to do this when redirecting empty-path routes. Otherwise, because an empty path is a prefix of any URL, the router would apply the redirect even when navigating to the redirect destination, creating an endless loop.

In the following example, supplying the 'full' pathMatch strategy ensures that the router applies the redirect if and only if navigating to '/'.

      
        content_copy
      
      [{
  path: '',
  pathMatch: 'full',
  redirectTo: 'main'
}, {
  path: 'main',
  component: Main
}]
    

Componentless Routeslink

You can share parameters between sibling components. For example, suppose that two sibling components should go next to each other, and both of them require an ID parameter. You can accomplish this using a route that does not specify a component at the top level.

In the following example, 'MainChild' and 'AuxChild' are siblings. When navigating to 'parent/10/(a//aux:b)', the route instantiates the main child and aux child components next to each other. For this to work, the application component must have the primary and aux outlets defined.

      
        content_copy
      
      [{
   path: 'parent/:id',
   children: [
     { path: 'a', component: MainChild },
     { path: 'b', component: AuxChild, outlet: 'aux' }
   ]
}]
    

The router merges the parameters, data, and resolve of the componentless parent into the parameters, data, and resolve of the children.

This is especially useful when child components are defined with an empty path string, as in the following example. With this configuration, navigating to '/parent/10' creates the main child and aux components.

      
        content_copy
      
      [{
   path: 'parent/:id',
   children: [
     { path: '', component: MainChild },
     { path: '', component: AuxChild, outlet: 'aux' }
   ]
}]
    

惰性加载link

Lazy Loadinglink

Lazy loading speeds up application load time by splitting the application into multiple bundles and loading them on demand. To use lazy loading, provide the loadChildren property instead of the children property.

Given the following example route, the router will lazy load the associated module on demand using the browser native import system.

      
        content_copy
      
      [{
  path: 'lazy',
  loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule),
}];
