vue3路由router.push的使用以及问题分析

// 字符串路径
router.push('/users/eduardo')

// 带有路径的对象
router.push({ path: '/users/eduardo' })

// 带查询参数，结果是 /register?plan=private
router.push({ path: '/register', query: { plan: 'private' } })

// 带 hash，结果是 /about#team
router.push({ path: '/about', hash: '#team' })

// 命名的路由，并加上参数，让路由建立 url
router.push({ name: 'user', params: { username: 'eduardo' } })

// 命名的路由，并加上参数，让路由建立 url
router.push({ name: 'user', params: { username: 'eduardo' } })

const routes = [
    { path: '/other-page', component: () => import('../views/OtherPage.vue') },    
];

try {
  this.$router.push({
    name: 'OtherPage', // 目标页面的路由名称
    query: {
      param1: 'value1',
      param2: 'value2'
    }
  });
} catch (error) {
  console.log(`router.push.err=${error}`)
}

router.push.err=Error: No match for
 {"name":"OtherPage","query":{"param1":"value1","param2":"value2"},"params":{}}

  const routes = this.$router.options.routes;
  console.log(routes)
  const routeNames = routes.map(route => route.name);
  console.log(routeNames);

{ path: '/other-page',name:'OtherPage', component: () => import('../views/OtherPage.vue') },

// NO1 和 NO2 两种写法均可
