我想验证来自golang前端的后端时区 [英] I want to validate timezone at the backend which is coming from the frontend in golang

问题描述

前端在注册期间发送时区以及其他用户详细信息.我需要在时区放置一个验证器以进行api测试.时区中的数据格式为:

The front-end is sending timezones along with other user details during sign up. I need to put a validator on timezone for api testing. The data in the timezone is of the format:

(GMT-10:00) Hawaii
(GMT-08:00) Pacific Time (US & Canada)

我所做的是在数组中定义所有时区，然后搜索接收到的时区.如果存在，则返回err.我的功能是:

What I did is define all the timezones in an array and then search for the received timezone. If it exists then ok else return err. My function is:

func timeZoneValidator(field validator.FieldLevel) bool {
    if field.Field().Kind() != reflect.String {
        return false
    }
    timeZoneField := field.Field().String()

    for i:= range timeZones {
        if timeZones[i] == timeZoneField {
            // Found!
            return true
        }
    }
    return false
}

但是我想使用一个库或可以为我完成此任务的东西.如果有，请告知.

But I want to use a library or something that does this task for me. If you got any, please advise.

推荐答案

您也许可以使用 time.LoadLocation .

You might be able to use time.LoadLocation.

func LoadLocation(name string) (*Location, error)

您可以传入诸如"America/New_York"之类的字符串，并且错误返回信息会告诉您它是否有效.

You can pass in a string such as "America/New_York" and the error return should tell you if it's valid.

请注意，格式将与您当前使用的格式不同.查看 https://www.iana.org/time-zones

Note the format will be different from what you currently have. Check out https://www.iana.org/time-zones
