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))
      }
    }
}
