lua-resty-qqwry

lua-resty版本的高性能客户端，用于解析纯真社区版IP库(qqwry.dat)

状态

此库经过生产环境长期验证

主要功能

1. 高性能: qqwry.dat数据库只在nginx启动的时候加载一次，后续完全基于内存查找，零IO

2. 基于FFI的libiconv调用，自动将结果字符集由GBK转为UTF-8

安装

    opm get axpwx/lua-resty-qqwry

使用

    http {
      init_by_lua_block {
        -- 将/path/to/qqwry.dat换成qqwry.dat的实际地址
        qqwry = require ('resty.qqwry').init('/path/to/qqwry.dat')
      }
    
      server {
        listen 80;
    
        location =/ip {
          content_by_lua_block {
            local json = require 'cjson'
            local ip = ngx.var.arg_ip or ngx.var.remote_addr
            local res, err = qqwry:lookup(ip)
            if err then
              ngx.say(err)
              ngx.exit(200)
            end
            ngx.header['Content-Type'] = 'application/json; charset=UTF-8'
            ngx.print(json.encode(res))
          }
        }
    }


    curl http://localhost/ip?ip=223.5.5.5
    
    {"region":"浙江省杭州市","isp":"阿里巴巴anycast公共DNS"}
