1. 路由嵌套和参数传递
传参的两种形式：
a.查询字符串：login?name=tom&pwd=123
{{$route.query}}
------
<li><router-link to="/user/login?name=wushi&pass=123">用户登录</router-link></li>
{{$route.query}}
b.rest风格url：regist/alice/456
{{$route.params}}
<li><router-link to="/user/regist/qwe/123">用户注册</router-link></li>
{{$route.params}}
c.{{$route.path}}
获取url路径
路由实例
router.push({path:'/home'}) 添加路由，功能上与<route-link>相同
router.replace({path:'/home'}) 替换路由，不产生历史记录
