I'm trying to pass requests from address helpme,com/donor/2014/12/07/Name on the other server.
URL like the: /donor/2014/12/07/Mike
need to convert to a query type of: /donor.php?yyyy=2014&mm=12&dd=07&donor=Name.
Now i have:
location ~* ^/donor/+$ {
rewrite ^/(.*) /donor.php?yyyy=$1&mm=$2&dd=$3&donor=$4 break;
proxy_pass http://164,151,234,168;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
Help me please.
The regex for that should be (untested) something like /donor/(\d{4})/(\d{2})/(\d{2})/(.+).
The use of commas (,) instead of periods (.) for the hostname/IP seems wrong, though. As far as I know the same character is used everywhere….

I have an issue into the configuration of my nginx proxy.
I just try to use regex has it is defined here: https://underthehood.meltwater.com/blog/2017/12/12/lightweight-tests-for-your-nginx-api-gateway/
But nothing works. My server won't start if it is any regex into the path.
I tried:
location ~ ^/tesla/(?<id>.*)$ {
proxy_pass http://localhost:8081/;
proxy_set_header Host $host;
}
or
location ~ ^/tesla/test/ {
proxy_pass http://localhost:8081/;
proxy_set_header Host $host;
}
or
location ~* ^/tesla/test/ {
proxy_pass http://localhost:8081/;
proxy_set_header Host $host;
}
Nothing work. My final aim is to extract a value from the url and do the following thing:
location ~* ^/(<version>.*)/test/ {
proxy_pass http://localhost:8081/;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-Prefix $version;
}
UPDATE (SOLVED)
I finally succeed thanks to Richard.
Here is the complete code:
location ~* ^/api/(?<version>.*)/(?<service>.*)(/.*/.*)$ {
proxy_pass http://$service.localnetwork:8080$3;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Prefix /api/$version/$service;
proxy_set_header msvc_name $service;
proxy_set_header msvc_version $version;
}
You can't use a proxy_pass with a static URI within a regular expression location block, it will throw an error - see your Nginx error log. See this document for details.
However, you can construct the URI to send upstream by appending variables to the proxy_pass statement. In your case, you could capture the remainder of the URI in the same regular expression.
For example:
location ~* ^/([^/]+)/test(/.*)$ {
proxy_pass http://localhost:8081$2;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-Prefix $1;
}
So I am trying to forward a url that contains a # and am having some difficulty. I have the following in the location sections:
location ~* /.%23/evl {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass https://foo.com;
}
location ~* /(?!.%23/evl) {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://bar.com;
}
I would like everything with
http://example.com/#/evl/* to goto foo.com
everything else to bar.com
Any help would be appreciated.
I have the following location config:
location ~ ^/(trucks|cars|planes|system|tools) {
auth_basic "Restricted";
auth_basic_user_file /etc/nginx/htauth_file;
proxy_set_header Host "server.lan";
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://127.0.0.1:8080$request_uri;
}
When anyone makes requests to
/trucks
or
/cars
etc, I want them to be authenticated by the basic auth. But when anyone makes requests to
/trucks?id=123
or
/cars?id=124
then I want no authentication, taken care of a lower location block.
I basically dont want the location to match when there is a question mark in the URI.
Is there a way to modify my pasted config so that it does not match when there is a question mark in the URI?
I suggest the following regex:
^/(trucks|cars|planes|system|tools)(?![^\s?]*\?)
DEMO.
Try following regex:
location ~ ^/[^?]+ {
auth_basic "Restricted";
auth_basic_user_file /etc/nginx/htauth_file;
proxy_set_header Host "server.lan";
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://127.0.0.1:8080$request_uri;
}
It will:
/cars <--match
/trucks <--match
/trucks?id=123 <-- no match
I have my frontend server running nginx. The backend is on another machine on the same VPN. This is its config:
server {
listen 80;
server_name *.vpn.domain.com;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://10.8.25.102:8100/;
proxy_redirect http://10.8.25.102:8100/ http://$server_name/;
}
}
I would like to pass a different host to the backend... I'd like the backend to receive, for requests done tosubdomain.vpn.domain.com the host subdomain.local.domain.com
Is there any way to do this? I'm looking for a regexp substitution (or even a substring substitution) but I'm having surprisingly little success... I thought it would be a piece of cake. I think the solution would be in the lines of
server {
listen 80;
server_name *.vpn.domain.com;
set $my_host $http_host;
replace $my_host .vpn. .local.
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $my_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://10.8.25.102:8100/;
proxy_redirect http://10.8.25.102:8100/ http://$server_name/;
}
}
It's just that I haven't found yet the proper syntax for replace $my_host .vpn. .local. I don't really care about multiple substitutions... I won't have a.vpn.a.vpn.domain.com
I finally figured it out, I can do
if ($http_host ~ ^(.*)\.vpn\.(.*)$) {
set $my_host $1.local.$2;
}
And then, as there're CSRF validations in place, I also need to rewrite the Referer... so this is how it ended up looking
server {
listen 80;
server_name *.vpn.domain.com;
set $my_host $http_host;
if ($http_host ~ ^(.*)\.vpn\.(.*)$) {
set $my_host $1.local.$2;
}
set $referer $http_referer;
set $referer_host no;
if ($http_referer ~ ^(https?://)([^/]+)(/.*)$) {
set $referer_host $2;
set $rewritten_referer $1$my_host$3;
}
if ($referer_host = $http_host) {
set $referer $rewritten_referer;
}
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $my_host;
proxy_set_header X-NginX-Proxy true;
proxy_set_header Referer $referer;
proxy_set_header IS_SECURE no;
proxy_pass http://10.8.25.102:8100/;
proxy_redirect https://$my_host/ https://$http_host/;
proxy_redirect http://$my_host/ http://$http_host/;
}
}
i'm getting trouble with my regex don't know what is wrong with it. it's returning a URi with orls/f instead of orls/f?p=4550. When i pass https://secure.toto02.com/orls/myservice/f?p=4550
my conf file is below
location ~ "^/([a-zA-Z]+)/myservice/(.+)$" {
error_log /var/log/nginx/error-server.log notice;
rewrite_log on;
#proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://192.168.3.45:8080/orls/$2;
proxy_redirect http://192.168.3.45:8080/orls/ https://secure.toto02.com/$1/myservice/ ;
}
Can anyone help?
Capturing the location will not encompass the query string. You have to manually include it via $is_args and $args variables like so:
proxy_pass http://192.168.3.45:8080/orls/$2$is_args$args;
