I am trying to rewrite the following url in NGINX:
https://example.com/ab12-cdef4567?c=123
Into this:
https://example.com/ab12-cdef4567.php?c=123
The pattern will always be {4 alphanumeric}-{8 alphanumeric}
This is what I am attempting without success:
rewrite ^/(.{4}-.{8})?(.*)$ /$1.php?$2 last;
You may try:
^(.*)(\w{4}-\w{8})(.*)$
Explanation of the above regex:
^, $ - Represents start and end of line respectively.(.*) - Represents first capturing group matching everything before alphanumeric pattern string.(\w{4}-\w{8}) - Represents second capturing group matching the required alphnumeric pattern. If you do not want to include _ then you can assign them manually; something like [0-9A-Za-z].(.*) - Represents third capturing group matching everything after alphanumeric pattern string.$1$2.php$3 - For the replacement part; you can use the first, second and 3rd capturing group along with .php extension.
You can find the demo of the above regex in here.
You cannot match the query string (?c=123) using rewrite. Nginx uses a normalised URI when matching location and rewrite statements, which has the query string removed.
The rewrite directive will append the original query string to the resulting URI unless the replacement string ends with a ?. See this document.
For example:
rewrite "^(/.{4}-.{8})$" $1.php last;
The entire regular expression needs to be in quotes because of the braces.
