这是对xxx.nginx转发+OpenResty(nginx升级版)_web服务器+lua_tgbyhn31的博客-CSDN博客 的一个补充，用于nginx处理请求参数。

附代码：

nginx 配置

#user  nobody;
worker_processes  1;
error_log  logs/error.log;
 
events {
    worker_connections  1024;
}
 
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    #lua 模块
    lua_package_path "/usr/local/openresty/lualib/?.lua;;";
    #c模块  
    lua_package_cpath "/usr/local/openresty/lualib/?.so;;";
 
    server {
        listen       8081;
        server_name  localhost;
        location ~ /api/item/(\d+) {
            # 默认的响应类型
            default_type application/json;
            # 响应结果由lua/item.lua文件来决定
            content_by_lua_file lua/item.lua;
        }
        location / {
            root   html;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

lua 代码（nginx的lua目录下的item.lua文件) 

--  获取路径参数
local id = ngx.var[1]
--  返回结果
