nginx 内置绑定变量 ngx.var.xxx

名称说明

$arg_name	请求中的name参数

$args	请求中的参数

$binary_remote_addr	远程地址的二进制表示

$body_bytes_sent	已发送的消息体字节数

$content_length	HTTP请求信息里的"Content-Length"

$content_type	请求信息里的"Content-Type"

$document_root	针对当前请求的根路径设置值

$document_uri	与$uri相同; 比如 /test2/test.php

$host	请求信息中的"Host"，如果请求中没有Host行，则等于设置的服务器名

$hostname	机器名使用 gethostname系统调用的值

$http_cookie	cookie 信息

$http_referer	引用地址

$http_user_agent	客户端代理信息

$http_via	最后一个访问服务器的Ip地址。

$http_x_forwarded_for	相当于网络访问路径

$is_args	如果请求行带有参数，返回“?”，否则返回空字符串

$limit_rate	对连接速率的限制

$nginx_version	当前运行的nginx版本号

$pid	worker进程的PID

$query_string	与$args相同

$realpath_root	按root指令或alias指令算出的当前请求的绝对路径。其中的符号链接都会解析成真是文件路径

$remote_addr	客户端IP地址

$remote_port	客户端端口号

$remote_user	客户端用户名，认证用

$request	用户请求

$request_body	这个变量（0.7.58+）包含请求的主要信息。在使用proxy_pass或fastcgi_pass指令的location中比较有意义

$request_body_file	客户端请求主体信息的临时文件名

$request_completion	如果请求成功，设为"OK"；如果请求未完成或者不是一系列请求中最后一部分则设为空

$request_filename	当前请求的文件路径名，比如/opt/nginx/www/test.php

$request_method	请求的方法，比如"GET"、"POST"等

$request_uri	请求的URI，带参数

$scheme	所用的协议，比如http或者是https

$server_addr	服务器地址，如果没有用listen指明服务器地址，使用这个变量将发起一次系统调用以取得地址(造成资源浪费)

$server_name	请求到达的服务器名

$server_port	请求到达的服务器端口号

$server_protocol	请求的协议版本，"HTTP/1.0"或"HTTP/1.1"

$uri	请求的URI，可能和最初的值有不同，比如经过重定向之类的
