Functions

func ClientIP

func ClientIP(r *http.Request) string

ClientIP 尽最大努力实现获取客户端 IP 的算法。 解析 X-Real-IP 和 X-Forwarded-For 以便于反向代理（nginx 或 haproxy）可以正常工作。

func ClientPublicIP

func ClientPublicIP(r *http.Request) string

ClientPublicIP 尽最大努力实现获取客户端公网 IP 的算法。 解析 X-Real-IP 和 X-Forwarded-For 以便于反向代理（nginx 或 haproxy）可以正常工作。

func ExtractIP

func ExtractIP(addr net.Addr) net.IP

ExtractIP extract IP from net.Addr

func ExtractPort

func ExtractPort(addr net.Addr) int

ExtractPort extract Port from net.Addr

func GlobalUnicastIP

func GlobalUnicastIP() (net.IP, error)

GlobalUnicastIP get a global unicast IP address

func GlobalUnicastIPString

func GlobalUnicastIPString() (string, error)

GlobalUnicastIPString get a global unicast IP address string

func IP2Long

func IP2Long(ip net.IP) (uint, error)

IP2Long 把net.IP转为数值

func IPString2Long

func IPString2Long(ip string) (uint, error)

IPString2Long 把ip字符串转为数值

func IPs

func IPs() []net.IP

IPs get all IP addresses

func InterfaceIPs

func InterfaceIPs(name string) ([]net.IP, error)

InterfaceIPs get public IP addresses by interface name

func InterfaceIPv4

func InterfaceIPv4(name string) (net.IP, error)

InterfaceIPv4 get a public IPv4 address

func IsLocalIP

func IsLocalIP(ip net.IP) bool

IsLocalIP 检测 IP 地址是否是内网地址 通过直接对比ip段范围效率更高

func IsLocalIPAddr

func IsLocalIPAddr(ip string) bool

IsLocalIPAddr 检测 IP 地址字符串是否是内网地址

func Long2IP

func Long2IP(i uint) (net.IP, error)

Long2IP 把数值转为net.IP

func Long2IPString

func Long2IPString(i uint) (string, error)

Long2IPString 把数值转为ip字符串

func PickFreePort

func PickFreePort() (int, error)

PickFreePort automatically chose a free port and return it

func RemoteIP

func RemoteIP(r *http.Request) string

RemoteIP 通过 RemoteAddr 获取 IP 地址， 只是一个快速解析方法。
