How to map requests from a path? - nginx

Question

I have the following domain:
https://example.com
I want, when the following /path/ is hit:
https://example.com/path/subpath/?param1=value1&param2=value2
​
the content from this url to be served:
https://example.com/subpath/?param1=value1&param2=value2
​
without performing a redirect.
​
I have tried using an alias like this:
​
location /path/ {
alias /home/forge/example.com/current/;
}
​
where current is a symlink pointing to the latest release:
​
current -> /root/example.com/releases/timestamp/
​
But it doesn't work. it gives 404.
How can I achieve this?
The entire server block:
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name example.com;
server_tokens off;
root /home/forge/example.com/current;
add_header X-Frame-Options "SAMEORIGIN";
add_header X-XSS-Protection "1; mode=block";
add_header X-Content-Type-Options "nosniff";
index index.html index.htm index.php;
charset utf-8;
location /path/ {
alias /home/forge/example.com/current/;
}
location / {
gzip_static on;
try_files $uri $uri/ /index.php?$query_string;
}
location = /favicon.ico { access_log off; log_not_found off; }
location = /robots.txt { access_log off; log_not_found off; }
access_log /var/log/nginx/example.com-access.log;
error_log /var/log/nginx/example.com-error.log error;
error_page 404 /index.php;
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}
location ~ /\.(?!well-known).* {
deny all;
}
gzip on;
}

I don't see any reason why
rewrite ^/path(/.*) $1;
didn't work as expected. But if you want to use an alias solution instead, you should take into account that regex matching locations have a greater priority than prefix ones and any request for /path/subpath/index.php would be processed by location ~ \.php { ... } rather than location /path/ { ... }. You can override this with ^~ location modifier using a second nested PHP handler:
location ^~ /path/ {
alias /home/forge/example.com/current/;
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}
}
