How to run a specific function when refreshing a router vue.js 2.0 page?

Question

Vue.js

How to find out the path of the vue.js router when loading the page and execute the parameters?
Example. There is a link site/users/:UserId
When you select a user, his data is loaded. But if I update, I can’t tie up the update function at startup.
That is, if the site/users/:UserId route is selected and the page has started, then you need to make a request to the server, and not only when you click on this link.
How to implement this?
