Rewrite for javascript files.. again, fire on live site


#1

Hello,

Somehow my rewrite for Javascript got broken again. I’ve tried every
possible combination of things I can think of. What I need is:

orig URL: http://mysite.com/javascript/fileA.js,fileB.js,fileC.js

…becomes…

dest URL:
http://mysite.com/combine.php?type=javascript&files=fileAjs.,fileB.js,fileC.js

So this is the latest variation I’ve tried, with the new nginx 0.7.40:

location ^/javascript/(.*)$ {
fastcgi_pass 127.0.0.1:10005;
fastcgi_param SCRIPT_FILENAME
/home/fugbert/www/live/escort-space/trunk/html/public/combine.php?type=javascript&files=$1;
fastcgi_param QUERY_STRING q=$request_uri;
include /etc/nginx/fastcgi_params;
}

** in fastcgi_params, I have the defaults except I commented out
QUERY_STRING line.

The error I’m getting is undefined index “type” which tells me that the
$_GET array is not available to combine.php.

This is hurting a live site.

Thanks in advance for your help,
Chris

It’s really strange: in my debug log I see

2009/03/10 21:35:31 [debug] 10047#0: *1 http request line: “GET
/javascript/fileA.js,fileB.js,fileC.js HTTP/1.0”

/home/fugbert/www/live/escort-space/trunk/html/public/combine.php?type=javascript&files=fileA.js,fileB.js,fileC.js”

I.e., SCRIPT_FILENAME is right.

I finally got this working but I had to go back to a rewrite method.

The relevant part of the config is:

location ~ /javascript/(..js) {
rewrite /javascript/(.
.js) /combine.php?type=javascript&files=$1
last;
}

(and similarly for css)

I’m not sure why I couldn’t get the non-rewrite method working. I am
not really clear on how QUERY_STRING works. For 99% of the php (the
code igniter part), setting the QUERY_STRING q=$request_uri does it (in
the CodeIgniter config you have to set the protocol to REQUEST_URI).
like so:

location / {
fastcgi_pass 127.0.0.1:10005;
fastcgi_param SCRIPT_FILENAME
/home/fugbert/www/live/escort-space/trunk/html/public/index.php;
fastcgi_param QUERY_STRING q=$request_uri;
include /usr/local/nginx/conf/fastcgi_params;
}

combine.php doesn’t work the way CodeIgniter does. It’s just a PHP
script that expects (for example)
?type=javascript&files=fileA.js,fileB.js,fileC.js

Hi All,
I did this for my customers (highly using apache before) to let them
convert htaccess rewrite rules to nginx. Check it from
http://www.anilcetin.com/convert-apache-htaccess-to-nginx/ If you have
any feedbacks please email me (anil?saog.net)

I tried going back to what I had previously posted here that worked, at
least for the location /javascript/ part. Now it gives me 503 error.

Here’s my config:

Thank you so much for the great tools. Hopefully someone will clarify if
it’s 100% correct


#7

Is the code available to look at and or use? It would be greatly
beneficial
to use on the commandline for me :s


#8

Oh that’s really helpful, it’s a real time saving tool. Thanks.

Max


#9

Hrm, I need to learn to read first. Sorry hah.


#10

No problem, I just updated the code, I think this time it is more close
to be a “working” thing :slight_smile: If anyone knows a way of getting environment
variables please inform me, I couldnt find if there is. (yes someone
said mod_parsed_vars thing but I am not sure of it, is this patch
applied already to nginx sources? if not so, the patch is very old to
apply I think)
