使用regexp查找更干净的nginx位置

Question

I would like to create a location that matches all but

http://uri/proxy-wmts

For example:

http://uri/proxy/toto
http://uri/proxy?param=value

I came out with that:

location  ~ ([^/]*)/proxy(\-[^w][^m][^t][^s])* 

But I think it's kind of ugly, I am looking for a cleaner solution.

As I already stated in my comment, using proper location order would be much easier and more performant (matching a constant string is faster than a regular expression).

location = /proxy-wmts {} # matches *exactly* /proxy-wmts
location /proxy {}

or

location /proxy-wmts {} # also matches /proxy-wmts....
location /proxy {}

would pretty much do what you want.

One regular expression you could apply here is a zero-length negative lookahead assertion (?!...) :

location ~ ([^/]*)/proxy(?!-wmts)

Which will match for

/uri/proxy
/uri/proxy-abc
/uri/proxy/abc
...

but not for

/uri/proxy-wmts
/uri/proxy-wmts-abc
/uri/proxy-wmts/abc
