Question

什么是仅从nginx日志中查找URI的完全匹配正则表达式（python）？

00.00.00.00 - - [23/Mar/2020:16:23:04 +0000] "GET /foo/bar/uri.js?id=123 HTTP/1.1" 200 19165 "https://nginx.com/foo/bar" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36" "00.00.00.00" 0.000

00.00.00.00 - - [23/Mar/2020:16:23:04 +0000] "GET /foo/bar/uri HTTP/1.1" 200 19165 "https://nginx.com/foo/bar" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36" "00.00.00.00" 0.000

00.00.00.00 - - [23/Mar/2020:16:23:04 +0000] "GET /foo/bar/uri.png HTTP/1.1" 200 19165 "https://nginx.com/foo/bar" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36" "00.00.00.00" 0.000

完全匹配正则表达式应在下面给出

/foo/bar/uri.js?id=123
/foo/bar/uri
/foo/bar/uri.png

与URI相匹配的正则表达式如下（click here）：

很显然，如果您不仅要匹配，而且要提取，这意味着删除所有其余部分，那么您也要匹配（click here）：

(?<=GET )([^ ]*)

并在替换中使用.*(?<=GET )([^ ]*).*（在Perl中；如果需要Python，则使用$1）。
