路径：{ path: '/a', redirect: '/b' }
命名的路由： { path: '/a', redirect: {name:'/foo'} }
动态重定向目标： { path: '/a', redirect: to => {
const {
query,
params,
hash
} = to
if (params.name) {
return
/${params.name}} else if (query.to && query.to === "bar") {
return
/${query.to}} else if (hash === '#baz') {
return '/baz'
}
}
}
