Nginx Change Request from PUT to POST

I'm using nginx for a PHP REST API that I'm working on. To be fully REST-ful, I'm using PUT/DELETE requests where appropriate. However, PHP doesn't parse the post body on PUT requests - which I need for this particular scenario.

I had considered parsing it myself, but a) I'd rather let PHP do it in C as it's considerably faster than any implementation I could come up with in PHP and b) there are a lot of edge cases that people have already spent a lot of time working around - I'd rather not duplicate those efforts.

On the API side, I have already added support to read the X-HTTP-Method-Override header and use that when available over the actual verb.

All I'm looking for now is a way, in nginx, to take a PUT request, and change it to a POST request with that header set.

I feel ike I have looked all over the place but can't find a solution. Anything would be helpful (even if you recommend a different parsing technique so I don't have to deal with this).

I think it's worth pointing out in case anyone else considers this method for processing a PUT request in PHP (or any other request method that isn't populated into some global $_WHATEVER array to make life easy) that the correct way to get the body of a put request is to read the contents of php://input.

Something like this should work:

$data = file_get_contents("php://input");

Nginx only informs FastCGI of the request method via REQUEST_METHOD param. So you may simply override the value and report anything you want to PHP. You'll have to declare another variable in your Nginx configuration, let's name it $fcgi_method, based on the original request method:

map $request_method $fcgi_method {
  default $request_method;
  PUT POST;
}

(note that map sections should be at http level, i.e. the same configuration level as server blocks)

Then you may use it in your location like so:

fastcgi_param REQUEST_METHOD  $fcgi_method;

It's important that this snippet is after typical include fastcgi_params or alike.
