我是靠谱客的博主还单身星月，最近开发中收集的这篇文章主要介绍nginx request的几个变量，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

nginx配置：

fastcgi_param
SCRIPT_FILENAME
$document_root$fastcgi_script_name;
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
HTTP_USER_AGENT
$http_user_agent;
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
HTTP_HOST
$host;
fastcgi_param
GATEWAY_INTERFACE
CGI/1.1;
fastcgi_param
SERVER_SOFTWARE
nginx/$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
HTTP_CLIENTIP
$remote_addr;
fastcgi_param
SCRIPT_URL
$request_uri;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param
REDIRECT_STATUS
200
location / {
root /home/fangfang/runroot;
rewrite ^/(.*)$ /index_9299.php?route=$1 break;
fastcgi_pass
phpserver;
}

请求：127.0.0.1:8282/ff?name=ff

变量值：

request:GET /ff?name=ff HTTP/1.0

uri:/index_9299.php

request_uri:/ff?name=ff

document_uri:/index_9299.php

request_filename:/home/fangfang/runroot/index_9299.php

args:route=ff&name=ff

query_string:route=ff&name=ff

SCRIPT_FILENAME:/home/fangfang/runroot/index_9299.php（此参数决定了php路径）

uri和request_uri的区别是前者随着rewrite改变，而后者不改变，现我还没有在nginx找到表示url:/ff的变量。
