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

  • Config.exts.lua <function> lua 文件加载策略

  • Config.exts.json <function> json 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)
