API

Config.path

• <string> 配置文件目录，默认为 ngx.config.prefix() .. "config"

Config.exts

• <table> 配置文件加载策略

自定义加载策略

; {ngx.config.prefix()}/config/master.ini
isMaster=true

-- in master
local Config = require "resty.config"
local fs = require "fs"
local String = require "utility.string"

Config.exts.ini = function(path)
  local content, err = fs.readFile(path)
  if not content then return nil, err end

  return String.split(content, "\n"):reduce(function(config, str)
    str = String.trim(str)

    if String.startsWith(str, "[") then return config end

    local fragments = String.split(str, "=")
    config[fragments[1]] = fragments[2]

    return config
  end, {})
end

local config = Config()
-- true
print(config.isMaster)
