正则表达式否定前瞻以匹配 url

Question

I'm trying to match urls /api/v1/users... /api/v1/other_stuff...

Except for /api/v1/users/invitation_register

I've been trying to use negative lookbehind

^\/api.*(?<!\binvitation_register\b)

and several similar constructs and have no idea how to actually do this. Any help would be more then welcome.

Answer 1

You can use this negative lookahead instead of lookbehind:

^\/api\/(?!v1\/users\/invitation_register\b).*

(?!v1\\/users\\/invitation_register\\b) is a negative lookahead that asserts that v1/users/invitation_register fails after /api/ .

RegEx Demo

If your intended match is always starting with /api/v1/... then you can use:

^\/api\/v1\/(?!users\/invitation_register\b).*

which asserts that users/invitation_register fails after /api/va/ .
