纠正以下go代码：package confconst env = devvar devConf = mapstringinterface port 8080var prodConf = mapstringinterface port 80var Conf = prodConfifenv==dev Conf = devConf

package conf

const env = "dev"

var devConf = map[string]interface{}{ "port": 8080, }

var prodConf = map[string]interface{}{ "port": 80, }

var Conf map[string]interface{}

func init() { if env == "dev" { Conf = devConf } else { Conf = prodConf } }
