Precisa do equivalente SCRIPT_URL do Apache em nginx + php-fpm

Question

Estou movendo um aplicativo herdado do Zend Framework para o Nginx + php-fpm. Aqui estão minhas configurações relevantes:

server {
  listen 80;

  server_name *.sandbox.journalexperts.com;
  port_in_redirect off;
  server_tokens off;
  autoindex off;

  include /etc/nginx/conf.d/assets.conf; # this file contains some info about not access logging robots.txt, favicon.ico, etc.

  client_max_body_size 15m;
  client_body_buffer_size 128k;

  root /wwwroot/vhosts/$host;
  index index.html index.php;
  access_log off;

  # deliver a static 404
  error_page 404 /404.html;
  location /404.html {
      internal;
      root html;
      allow all;
  }

  # Deliver 404 instead of 403 "Forbidden"
  error_page 403 = 404;

  # Deny access to hidden files
  location ~ /\. {
      deny all;
      access_log off;
      log_not_found off;
  }

  location / {
      try_files $uri $uri/ /index.php$is_args$args;
  }

  location ~ \.php$ {
      include /etc/nginx/conf/fastcgi.conf;

      fastcgi_intercept_errors on;
      fastcgi_ignore_client_abort off;
      fastcgi_connect_timeout 60;
      fastcgi_send_timeout 180;
      fastcgi_read_timeout 180;
      fastcgi_buffer_size 128k;
      fastcgi_buffers 4 256k;
      fastcgi_busy_buffers_size 256k;
      fastcgi_temp_file_write_size 256k;

      fastcgi_pass 127.0.0.1:9000;
      fastcgi_index index.php;
  }
}

Este é o meu arquivo fastcgi.conf:

fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param REQUEST_URI $request_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 $host;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

# http://wiki.nginx.org/HttpFastcgiModule#fastcgi_split_path_info
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;

fastcgi_param SCRIPT_URL $script_url; # This is a mapped variable.
fastcgi_param SCRIPT_URI $scheme://$http_host$script_url; # Uses above mapped variable.

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  PHP_SELF           $uri;
fastcgi_param  HTTPS              $https if_not_empty;

Eu preciso imitar o comportamento de SCRIPT_URL e SCRIPT_URI conforme eles são preenchidos no Apache. Eu encontrei este tópico onde o cartaz usou map para preencher esses itens.

map $uri $script_url {
    ~^(?<script_filename>.+\.(php|html))(?<path_info>.+)$ $path_info;
    ~^(?<script_filename>.+\.(php|html))$ $script_filename;
}

Isso, infelizmente, não funciona para mim e mostra /index.php como o SCRIPT_URI. Eu suspeito que isso é por causa do meu bloco try_files onde eu envio a solicitação para /index.php. Isso é suportado pela documentação do Nginx:

$uri
This variable is the current request URI, without any arguments (see $args for those). This variable will reflect any modifications done so far by internal redirects or the index module. Note this may be different from $request_uri, as $request_uri is what was originally sent by the browser before any such modifications. Does not include the protocol or host name. Example: /foo/bar.html

Ok, vamos tentar reescrever o mapa usando $request_uri .

map $request_uri $script_url {
    default $request_uri;
    ~^(?<script_filename>.+\.(php|html))(?<path_info>.+)$ $path_info;
    ~^(?<script_filename>.+\.(php|html))$ $script_filename;
}

Isso é um pouco melhor, mas ainda não alcança o resultado desejado. Aqui está o que eu recebo no Apache:

$_SERVER['SCRIPT_URL']: /tos/show.php/article/0000
$_SERVER['SCRIPT_URI']: http://example.com/tos/show.php/article/0000

Isso é o que eu recebo no Nginx:

$_SERVER['SCRIPT_URL']: /tos/show.php/article/0000?hello=world
$_SERVER['SCRIPT_URI']: http://example.com/tos/show.php/article/0000?hello=world

Eu não sei como fazer isso.

    

Answer 1

Isso foi o que acabei fazendo, o que funciona.

nginx.conf, no bloco http {}:

map $request_uri $my_script_url {
    default $request_uri;
    ~^(?<script_filename>.+\.(php))(.*)?$ $script_filename; #/test.php or /test.php?hello=world
    ~^(?<script_filename>.*)(\?.*)$ $script_filename; #/tos?hello=world
    ~^(?<script_filename>.*)(\?.*)?$ $script_filename; #/tos or /tos/hello/world or /tos/hello/world?omg=what
}

Coisas que aprendi:

• as expressões regulares são correspondidas de cima para baixo e o processamento é interrompido quando a primeira correspondência é encontrada.
• a documentação do nginx poderia ter feito muito mais para mim do que realmente aconteceu.

Dentro do bloco {} do servidor:

location / {
    try_files $uri $uri/ /index.php$is_args$args;
}

location ~* \.php(.*)?$ {
    include /etc/nginx/conf/fastcgi.conf;
    [...]
}

fastcgi.conf:

fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param REQUEST_URI $request_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 $host;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

# http://wiki.nginx.org/HttpFastcgiModule#fastcgi_split_path_info
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;

fastcgi_param SCRIPT_URL $my_script_url;
fastcgi_param SCRIPT_URI $scheme://$http_host$my_script_url;

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  PHP_SELF           $uri;
fastcgi_param  HTTPS              $https if_not_empty;

try_files $uri =404;

php.ini:

; cgi.fix_pathinfo = 1

Parece que você só precisa remover os parâmetros da consulta:

map $request_uri $script_url {
    default $request_uri;
    ~^(?<script_filename>.+\.(php|html))(?<path_info>.+)(\?.*)?$ $path_info;
    ~^(?<script_filename>.+\.(php|html))(\?.*)?$ $script_filename;
}
