需要一个javascript正则表达式来匹配特定的路径

Question

I need help to match a url that matches only if

• the path matches exactly /gummybear/ or /gummybear (case sensetive)
• the protocol is http or https
• the domain/host/port/hash can be anything

the regex should not match if

• the path is /gummybear/foobar
• it contains search parameters such as ?query=string

So far i got this:

/^http[s]?:\/\/?[^\/\s]+\/gummybear[\/]?/

examples it should be true for

https://www.example.com:81/gummybear/
http://www.example.com/gummybear#top
https://example.com:81/gummybear#/foobar/?search=params
http://www.exa.mple.com:81/gummybear
https://example.com:81/gummybear/#/exaple/1234/

examples that it should be false for

https://www.example.com:81/foo/gummybear/
https://www.example.com:81/guMmybear/
https://www.example.com:81/gummybear.html
http://www.example.com/gummybear/apple#top
file://example.com:81/gummybear#/foobar/?search=params
http://www.exa.mple.com:81/gummybear?search=apple#lol
https://example.com:81/#/gummybear/
http://www.test.com:81/dir/dir.2/index.htm?q1=0&&test1&test2=value#top

Answer 1

For your specific needs, I can come up with this regex:

^https?://[^/]+/gummybear(?:/?|/?#.*)$

Working demo

I haven't escaped slashes to make it more readable, but for javascript you can use:

^https?:\/\/[^\/]+\/gummybear(?:\/?|\/?#.*)$
