Forum: NGINX PATH_INFO

PATH_INFO is supposed to be decoded by the server and then passed to
the CGI application.

How can I do that from nginx.  My PATH_INFO never gets decoded and it
throws off my CGI scripts.

Dave,

    There is no support for CGI in Nginx. You have to FastCGI or HTTP 
(proxy)

Yeah, I'm passing everything to FastCGI.

I'm using something similar to this:

location \.php(/|$) {
>
> fastcgi_param SCRIPT_FILENAME /path*/to/*$script_name;
> fastcgi_param PATH_INFO $path_info;
> }
>
>

but really $path_info should be url_decoded before being set as a
fastcgi_param.  Since the CGI spec says:

The extra path information, as given by the client. In other words, 
scripts
> can be accessed by their virtual pathname, followed by extra information at

But is there a way that I can just do

fstcgi_param PATH_INFO urldecode($path_info); ?

>From php.ini:

; cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for 
CGI.  PHP's
; previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and 
to not grok
; what PATH_INFO is.  For more information on PATH_INFO, see the cgi 
specs.  Setting
; this to 1 will cause PHP CGI to fix it's paths to conform to the spec. 
A setting
; of zero causes PHP to behave as before.  Default is 1.  You should fix 
your scripts
; to use SCRIPT_FILENAME rather than PATH_TRANSLATED.

Try setting

cgi.fix_pathinfo=0

in php.ini

Nope, that doesn't work either.  I instead opted to use a PHP script to
urldecode the data (using the prepend options in php.ini).  It works for
now, not ideal, but I get to use nginx.

Anibal,

I am using a FastCGI server that nginx calls.  Right now (through
regexp) it takes the URL and figures out what part is the script
(blah.php) and what's the pathinfo (/q/string as in http://nginx/
blah.php/q/string).

But I need to decode the PATH_INFO before I pass it as a fast_Cgi
param.  is their a way to do that?
