I want to configure regular expression on location
example: /order-service/js/app.js or /order-service/js/xxxx/xxxxxx/app.js like this,
So order-service will be set proxy_pass://order-service/js/xxxx/xxxxxx/app.js
that means I will get 2 variables, one is order-service, and another is /js/xxxx/xxxx/app.js, so how can I write the URL wildcard?
location ~ ^/(order-service)(/js/.*) {}
or more specific:
location ~ ^/(order-service)(/js.*/app.js) {}

My nginx should match these requests:
/id/12345
/id/12345/qualifier
and /qualifier should be optional.
i want to use in a small lua openresty script the two matched groups (12345, qualifier) with ngx.var[]
i am trying with this location, but is not working for me.
how i can say that / and qualifier are optional?
location ~ ^/id/(\d+)(/?)(\w+?)$ {
^/id/(\d+)(?:/(\w+))?$
(?:) is a non-capturing group.
i want to support all level subdomains to "domain.com" for my configuration. That's possible with:
server_name "~^(?<sub>.+)\.domain\.com$";
My root looks like this:
set $subDirectory subdomains/$sub/;
set $root /var/www/domain.com/$subDirectory/www/;
root $root;
Example:
"abc.domain.com" will be /var/www/domain.com/subdomains/abc/www/
Now i want to support all level subdomains. For every sub i want to set in root between domain.com/HERE/www/ subdomains/$sub/. How can i do it?
"abc.domain.com" will be /var/www/domain.com/subdomains/abc/www/
"test.abc.domain.com" should be /var/www/domain.com/subdomains/abc/subdomains/test/www/
"hello.test.abc.domain.com" should be /var/www/domain.com/subdomains/abc/subdomains/test/subdomains/hello/www/
Currently "$sub" is for the last example hello.test.abc;.
Could i copy "$sub" to "$subRoot" and can replace all the points (.) on $subRoot with "/subdomains/"?
$subRoot looks then like "hello/subdomains/test/subdomains/abc"
My url format :
http://example.org/img?src=http://a.com/logo.png
I want nginx to rewrite this request to http://example.org/logo.png
(not url redriect)
how to do this?
The src argument is available as the $arg_src variable, however, you will need to use an if block to extract the part that you need. See this caution on using if.
For example (and you will need to adapt the regex to your specific needs):
location = /img {
if ($arg_src ~ \w(?<src>/\w.*)$) {
rewrite ^ $src last;
}
}
See nginx documentation here and a useful resource for regular expressions here.
I need to know how do i do a proxy pass in nginx for certain url pattern only
i have written following but i am not sure whether its working as i wanted. What i wanted is
1. if the url matches '/member-chat' it needs to be redirected the proxy pass
2. anything else needs to be re-written as below
is what have written is correct ?
location ^/member-chat {
proxy_pass http://lxx.com:5280/http-bind;
}
location !/member-chat {
rewrite ^/files/([^/]+)/([^/]+)$ /_files/$1/$2;
rewrite ^/plugins/([^.]+) http://www.lxx.com:9090/plugins/$1;
}
if i do this as below
location / {
rewrite ^/files/([^/]+)/([^/]+)$ /_files/$1/$2;
rewrite ^/plugins/([^.]+) http://www.lxx.com:9090/plugins/$1;
}
i get a error
nginx: [emerg] duplicate location "/" in /var/www/vhosts/system/lxx.com
/conf/vhost_nginx.conf:4
nginx: configuration file /etc/nginx/nginx.conf test failed
Several issues:
Your location #1 location ^/member-chat is wrong
because ^ to match the beginning of the path only works with regular expression matching (location ~ or location ~* for case-sensitive/-insensitive expression matching).
Either do location /member-chat which will also match locations like /member-chatABCDE or /member-chat/xyz
or use location = /member-chat to only match /member-chat.
You can also use regular expressions like location ~ ^/member-chat (prefix-match) or location ~* ^/member-chat$ (exact match), but avoiding regular expressions in favor of prefix or even better exact matches is recommended
(regular expressions have much worse performance and are compared at the very last in the matching process).
Location #2 is just plain wrong because there is nothing like a not operator for location matching.
nginx will process locations in a certain order, e.g. it will start with exact matches (=), then check for prefix-matches (no modifier) and afterwards check for regular expressions (~ or ~*).
However, if a regular expression match is found, it will be favored over the prefix-match.
Conclusion
location = /member-chat {
# exact match
# proxy stuff for chat goes here
}
location /files {
# match files
}
location /plugin {
# match plugin
}
I really recommend you to read the nginx docs to prevent you from asking one question after another.
E.g. location matching is a complex topic but so far well covered by the docs already.
Hi need help to reqrite this rule from apache to nginx, trying all day but nothing:
apache:
^pimage/small-([^/.]+)-([^/.]+).jpg$ /img_on_fly.php?iname=$1&iuid=$2&isize=small
tried with all online converters, tried everything I found online and nothing. I have no experience with nginx but other 15 rules rewrited one by one, but all were simple than this, so if someone can. Also, I am not sure what is "location" for this rule in nginx conf?
try the following in the server element of your conf file
location ~ ^\/pimage\/small\-(?<iname>[^\/\.]+)\-(?<iuid>[^\/\.]+)\.jpg$ {
try_files $uri /img_on_fly.php?iname=$iname&iuid=$iuid&isize=small
}
your conf file should look like:
server {
...
...
...
}
you can just change it to
server {
...
...
...
location ~ ^\/pimage\/small\-(?<iname>[^\/\.]+)\-(?<iuid>[^\/\.]+)\.jpg$ {
try_files $uri /img_on_fly.php?iname=$iname&iuid=$iuid&isize=small
}
}
What about escaping the dots, like so:
rewrite ^pimage/small-([^/\.]+)-([^/\.]+).jpg$ /img_on_fly.php?iname=$1&iuid=$2&isize=small;
try it and comment back.
UPDATE:
Try escaping the dashes too, like so:
rewrite ^pimage/small\-([^/\.]+)\-([^/\.]+).jpg$ /img_on_fly.php?iname=$1&iuid=$2&isize=small;
After try that, try also the variation of "dots not escaped and dashes escaped".
