Functions

func IsCellphoneOfChina

func IsCellphoneOfChina(str string) bool

IsCellphoneOfChina regular expression is used to check whether the telephone number is china.

func IsEmail

func IsEmail(str string) bool

IsEmail Use a regular expression to check whether the email address is valid.

func IsIPv4

func IsIPv4(str string) bool

IsIPv4 regular expression is used to check whether the IP address is IPV4.

func IsInternalIPv4

func IsInternalIPv4(str string) bool

IsInternalIPv4 Use a regular expression to check whether the ip address is ipv4.

func IsTelephoneOfChina

func IsTelephoneOfChina(str string) bool

IsTelephoneOfChina regular expression is used to check whether the telephone number is china.

func IsTimeHourPoint

func IsTimeHourPoint(str string) bool

IsTimeHourPoint matched time str is time hour point. str similar 00:01/05:28/19:25/23:59

func IsWebDomain

func IsWebDomain(str string) bool

IsWebDomain Use a regular expression to check whether the web domain is valid.

func RegularMatchString

func RegularMatchString(patten string, s string) (bool, error)

RegularMatchString reports whether the string s contains any match of the regular expression pattern. More complicated queries need to use Compile and the full Regexp interface.

func RegularReplaceMatch

func RegularReplaceMatch(patten string, original string, replace string) (string, error)

RegularReplaceMatch Use a regular expression to replace original string to novel string. The underlying call is regexp.Compile(patten).ReplaceAllString() method.
