1.验证是否匹配正则;

package lib

import (
    "regexp"
)

func IsEmail(email string) bool {
    if email != "" {
        if isOk, _ := regexp.MatchString("^[_a-z0-9-]+(\\.[_a-z0-9-]+)*@[a-z0-9-]+(\\.[a-z0-9-]+)*(\\.[a-z]{2,4})$", email); isOk {
            return true
        }
    }

    return false
}

func IsPhone(phoneStr string) bool {
    if phoneStr != "" {
        if isOk, _ := regexp.MatchString(`^\([\d]{3}\) [\d]{3}-[\d]{4}$`, phoneStr); isOk {
            return isOk
        }
    }

    return false
}

 

2.用正则抽取信息

re :=regexp.MustCompile("[\u0020-\u002F]|[\u003A-\u0040]|[\u005B-\u0060]|[\u00A0-\u00BF]")

re.MatchString(str)
