Go如何实现枚举小实例分享

package handler

const (
StatusDefaultError  = 1
StatusAuthFaild     = 600
StatusUnknowAction  = 601
StatusPostArgsError = 602
StatusNotValidFile  = 603
)

var statusText = map[int]string{
StatusDefaultError:  "Unknow Error",
StatusAuthFaild:     "Authentication Failed!",
StatusUnknowAction:  "Unknow Action",
StatusPostArgsError: "Post Args Error",
StatusNotValidFile:  "Not Is A Valid Zip File",
}

func StatusText(code int) string {
str, ok := statusText[code]
if ok {
return str
}
return statusText[StatusDefaultError]
}
