just trying to work out the regex for this. Say I have to following list of URL paths

/v1/users/
/v1/users/123abc/
/v1/users/123abc/456def/
/v1/users/123abc/456def/789ghi/
/v1/users/123abc/me/
/v1/users/123abc/me/456def/

where some parts are set, like v1 and users, and some parts are path parameters so they can be any values/characters, like 123abc and 456def.

What regex pattern can I put in place for the path parameters so it matches against the right ones.

For example, I tried to get /v1/users/123abc/456def/ using ^/v1/users/.*?/.*?/$. However, this regex matched with the following:

/v1/users/123abc/456def/
/v1/users/123abc/456def/789ghi/
/v1/users/123abc/me/
/v1/users/123abc/me/456def/

I understand it may be impossible to not match with /v1/users/123abc/me/ however I have a way around this if someone can find a solution which can get both /v1/users/123abc/456def/ and /v1/users/123abc/me/.

Thanks in advance.

CodePudding user response：

You can replace both .*? with [^/]* or even [^/] (as subparts must contain at least one char) and use

^/v1/users/[^/] /[^/] /$

See the regex demo.

Details:

• ^ - start of string
• /v1/users/ - a literal string
• [^/] - one or more chars other than /
• / - a / char
• [^/] - one or more chars other than /
• / - a / char
• $ - end of string.
