HarmonyOS 怎么跨模块路由跳转界面

import router from ‘@ohos.router’; 
import(‘library/src/main/ets/pages/Index’) // 引入共享包中的命名路由页面，如果存在红色波浪线，不影响编译打包 
@Entry 
@Component 
struct Index { 
 build() { 
  Text(‘点击’).onclick(()=>{ 
   router.pushNamedRoute({ 
    name: ‘harA’ 
   }) 
  }) 
 } 
}

@Entry({ routeName : ‘harA’ }) 
@Component 
export struct HarA { 
} 
 
@Entry({ routeName : ‘harA’ }) 
@Component 
export struct HarA { 
 build() { 
  Text(‘点击’).onclick(()=>{ 
   router.pushNamedRoute({ 
    name: ‘harB’ 
   }) 
  }) 
 } 
} 
 
@Entry({ routeName : ‘harB’ }) 
@Component 
export struct HarB { 
}
