注释很详细，直接上代码

上一篇

本篇建立在之前篇目前提下针对重定向进行演示

新增内容
路由重定向写法

源码

src/router/index.js

//导入所需模块
import Vue from "vue";
import VueRouter from "vue-router";
import myMusic from "@/views/myMusic.vue";
import findMusic from "@/views/findMusic.vue";
import attentionSigner from "@/views/attentionSigner.vue";
import recommendList from "@/views/recommendList.vue";
import rankingList from "@/views/rankingList.vue";
import songList from "@/views/songList.vue";
//调用函数将VueRouter插件安装为Vue的插件
Vue.use(VueRouter);

//配置路由规则
const routes = [
  //重定向
  { path: "/", redirect: "/MyMusic/recommendList" },
  {
    path: "/myMusic",
    component: myMusic,
    // 二级路由无需写'/'
    children: [
      {
        path: "recommendList",
        component: recommendList,
      },
      {
        path: "rankingList",
        component: rankingList,
      },
      {
        path: "songList",
        component: songList,
      },
    ],
  },
  {
    // 动态路由接受参数（后面加问号表示为可选参数）
    path: "/findMusic/:name?",
    component: findMusic,
  },
  {
    path: "/attentionSigner",
    component: attentionSigner,
  },
];

//创建路由实例
const router = new VueRouter({
  // 路由配置
  routes,

  //这里可以修改router-link的默认类名
  /*
    linkActiveClass:'my-active-class',
    linkExactActiveClass:'my-exact-active-class'
    */
});
//导出路由实例
export default router;
