for example, the route name is
"test1","test2"
the URL is
domain.com/test1 or domain.com/test2
how to get this full address
in the official document, there is only one $route.path whose address is obtained through the current route

the complete address does not need to be obtained by route, can't the native location.href be obtained?
console.log (location); print location, to see what you want
