nginx rewrite rule to overwrite $uri as well

  • 772

I have an URL like ^/d/something/(.*)$, what I want to do is rewrite it internally, with no permanent or temporary HTTP redirect, so that $_SERVER['REQUEST_URI'] will have just $1 and not the whole ^/d/something/(.*)$. Using nginx.

Here is what I tried:

location /d/something/ {
  rewrite "^/d/something/(.*)$" /$1 last;
}

location / {
    include php-fcgi.conf;
    try_files $uri $uri/ /index.php$args;
}

in the php-fcgi.conf there is fastcgi_param REQUEST_URI $request_uri; and $request_uri remains the same, so when I hit /d/something/something2 symfony reouter, which relies on $_SERVER['REQUEST_URI'] shows /d/something/something2 while I expect it to be just /something2. I assume that's because $request_uri is not changed.

If I replace it with fastcgi_param REQUEST_URI $uri; then $_SERVER['REQUEST_URI'] becomes / , no matter what I send in something2 part, it's always just /. Why is that happening and how can I internally rewrite it to /$1?

Thanks!

UPDATE: here are the contents of php-fcgi.conf:

location ~ \.php {
  include fastcgi_params;
  fastcgi_pass   127.0.0.1:9000;
  fastcgi_read_timeout 60s;
}

    I would expect $uri to have the value /index.php by the time the request is passed to the PHP script, so I don't understand why you are seeing /. However...

    The simplest solution would be to execute the PHP script from within the location where the URI is rewritten. This is achieved using a rewrite...break and overwriting the REQUEST_URI and SCRIPT_FILENAME parameters.

    For example:

    location /d/something/ {
    rewrite "^/d/something/(.*)$" /$1 break;

    include fastcgi_params;
    fastcgi_param  REQUEST_URI      $uri;
    fastcgi_param  SCRIPT_FILENAME  $document_root/index.php;

    fastcgi_pass   127.0.0.1:9000;
    fastcgi_read_timeout 60s;
}

    Place the fastcgi_param statements after the include statement.

    Alternatively, use a regular expression location block. Note that the order of regular expression location blocks is significant. See this document for details.

    For example:

    location ~ ^/d/something(/.*)$ {
    try_files /index.php =404;

    include fastcgi_params;
    fastcgi_param  REQUEST_URI  $1;

    fastcgi_pass   127.0.0.1:9000;
    fastcgi_read_timeout 60s;
}
