我无法在列表视图中配置路由参数 . 单击链接时，ContentViewer组件无法打开 . 调试写入错误：
1.Uncaught（承诺）：错误：无法匹配任何路由 .
2.未处理的承诺拒绝：无法匹配任何路线 . 网址段：'components / input';区域：角;任务：Promise.then;值：
这是我的主要服务 .
const LSNS = [
{ name: 'Helpers' ,
items: [
{ id : "autocomplete" , name : "Autocomplete" },
{ id : "checkbox" , name : "Checkbox" },
{ id : "input" , name : "Input" },
]
},
{ name: 'front-back-end',
items: [
{ id : "video_chat", name : "Video chat" },
{ id : "audio_chat", name : "Audio chat" },
{ id : "simple_chat", name : "Simple chat"},
{ id : "another", name : "Another"}
]
}
]
const BMJ = LSNS.reduce((function(a,b){
return a.concat(b.items);
}), []);
@Injectable()
export class LSNDiscriptionService {
getItemLSNS(): Hlsns[] {
return LSNS;
};
getBMJ(id:string) {
return BMJ.find(bm => bm.id === id);
};
};
我的路由 .
{ path: 'web_app', component: LeftSideNav,
children:[
{ path:'', component: BossContent },
{ path:'components/:id', component: ContentViewer }
HTML
<nav *ngFor="let lsn of lsns" class="lsnss" >
<h3>{{ lsn.name }}</h3>
<ul class="lsns">
<li *ngFor="let bm of lsn.items" class="lop" >
<a [routerLink]="['/components', bm.id]">{{bm.name}}</a>
未显示的组件
import { Component, OnInit } from '@angular/core';

您当前的实现指示一个绝对路由，您希望导航到子路由 . 在子路由前添加父路径可能会解决问题 .
