Initial navigation allows missing the base part

[donne1226]

Version

3.0.3

Reproduction link

https://codesandbox.io/s/pyl49

Steps to reproduce

set url /home or /app/home

What is expected?

/app/home -> direct to home page.
/home -> direct to blank page.

What is actually happening?

/app/home -> direct to home page.
/home -> direct to home page.

---

I wonder know if this is a bug or feature? And I expect /home should not link to home page, do I use the 'base' option correctly

The base prefix in path will be trimmed here, while a path without a leading base will be used directly.

vue-router/src/history/html5.js

Lines 74 to 80 in 9b01cbc

	export function getLocation (base: string): string {
	let path = decodeURI(window.location.pathname)
	if (base && path.indexOf(base) === 0) {
	path = path.slice(base.length)
	}
	return (path || '/') + window.location.search + window.location.hash
	}

It looks like a issue to me too, can we change the behavior?

This should indeed not happen

Coming back at this: the point of the base attribute is to allow serving an application from a different folder in your server like example.com/app instead of example.com. This means that the server must serve the application bundle only at /app. It shouldn't be serving an app at the root that uses a base option to /app and this scenario shouldn't exist
