10.6命名路由

注意点1：
命名路由请使用name属性，替换掉path属性的作用，且name直接指定名称即可，而path必须指定3级目录（path=’/demo/test/welcome’）才行。

注意点2：
name属性必须包裹在<router-link>标签里面才能使用，举例比如放在App.vue中有2种写法
写法1：用最普通的to属性跳转

<router-link class="list-group-item" active-class="active" to="/about">About</router-link>

写法2：:to属性，且用{}包裹，明显这种写法太费事

<router-link class="list-group-item" active-class="active" :to={“name”:"/about"}>About</router-link>

案例：将案例改为“命名路由”
