variable capture in Nginx location matching
Solution 1:
Old thread but I had the same problem...
I think the error isn't related to the PCRE version installed
NGINX doesn't parse your regex if your location tag doesn't start with ~ You need to use something like this
location ~ ^/a/b/(?<myvar>[a-zA-Z]+) {
# use variable $myvar here
if ($myvar = "sth") { ... }
}
Solution 2:
As Stefano Fratini correctly pointed out in his answer, your location
declaration has an error: for regular expressions you should use ~
alone, not ^~
.
Named captures are a feature of PCRE and they have different syntax available in different versions. For the syntax you use ?<var>
you must have PCRE 7.0 at least.
Please see the extensive information in official Nginx documentation
Solution 3:
^~ is not regex match, it stands longest matching prefix. you should use ~ or ~* (case insenstive) instead
Solution 4:
Untested, but the correct way to capture a block into a named variable using PCRE is (?P). So your example misses the P.
