NGINX: route to index.php within alias for specific path component with query string

Question

This is legacy app (Zend framework 1), we are moving from apache to nginx. We have front controller which dispatches to specific controller/action based on request URI.

Requirement

 1. www.example.com --> /home/user/www/public/index.php 2. www.example.com/a/b --> /home/user/www/public/index.php 3. www.example.com/api --> /home/user/api/public/index.php 4. www.example.com/api/a/b --> /home/user/api/public/index.php 5. www.example.com/api/a/b?x=1 --> /home/user/api/public/index.php 

Current Config

 location /api { alias /home/user/api/public/; try_files $uri /api/index.php; location ~ \.php$ { fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include /etc/nginx/fastcgi_params; } } 

Here is what PHP scripts receives

array ( [USER] => www-data [HOME] => /var/www [FCGI_ROLE] => RESPONDER [SCRIPT_FILENAME] => /home/user/api/public//index.php [QUERY_STRING] => [REQUEST_METHOD] => GET [CONTENT_TYPE] => [CONTENT_LENGTH] => [SCRIPT_NAME] => /api/index.php [REQUEST_URI] => /api/account/get?id=1 [DOCUMENT_URI] => /api/index.php ... ) 

Problem Above config is working fine. But query string is missing, so $_GET is empty.

Hack: Generate $_GET from Request URI before front controller dispatches.

$arr = explode("?",$_SERVER['REQUEST_URI']); if (count($arr) == 2 && count($_GET) == 0){ parse_str($arr[1], $_GET); } 

But I would like fix this at server level, please tell me how to pass query string in this case. Thanks in advance.

[EIDT] /etc/nginx/fastcgi_params

fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_FILENAME $request_filename; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param HTTPS $https if_not_empty; # PHP only, required if PHP was built with --enable-force-cgi-redirect fastcgi_param REDIRECT_STATUS 200;

Answer 1

You're missing it because you're not passing it.

fastcgi_param QUERY_STRING $query_string; 

And, by the way, you need the $_SERVER['QUERY_STRING'].

Answer 2

You need to check that /etc/nginx/fastcgi_params is as shipped by the vendor, and has not been altered in any way. If it has been changed at all, you should restore a clean copy.

Also, when using alias in a location, you need to have matching trailing slashes.

You currently have:

 location /api { alias /home/user/api/public/; 

But this should be:

 location /api/ { alias /home/user/api/public/; 

Without this, depending on which trailing slash is missing, URLs may have double slashes (which Linux doesn't care about, but web applications might) or URLs may not have a slash at all (which always breaks).
