vue-router参数传递

1.在vue-router中，有两大对象被挂载到了实例this
2.$route(只读、具备信息的对象)、$router(具备函数功能)
3.查询字符串方式传递参数
1).去哪里 <router-link :to="{name:'detail'，query：｛id:1｝}">xxx</router-link>
2).路由导航设置{name:'detail',path:'/detail',组件}
3).去了干嘛,获取路由参数(要注意是query还是params和对应的id名) this.$router.query.id

4.path方式传递参数
1).去哪里 <router-link :to="{name:'detail'，params:｛id:1｝}">xxx</router-link>
2).路由导航设置(path方式需要在路由规则上加上/:xxx){name:'detail',path:'/detail/id',组件}
3).去了干嘛,获取路由参数(要注意是query还是params和对应的id名) this.$router.params.id
