func BaseAdornStcp

func BaseAdornStcp(method, password string) func(conn net.Conn) net.Conn

BaseAdornStcp base adorn encrypt with method and password

func BaseAdornTLSClient

func BaseAdornTLSClient(conf *tls.Config) func(conn net.Conn) net.Conn

BaseAdornTLSClient base adorn tls client

func BaseAdornTLSServer

func BaseAdornTLSServer(conf *tls.Config) func(conn net.Conn) net.Conn

BaseAdornTLSServer base adorn tls server

func DialContext

func DialContext(ctx context.Context, d Dialer, network, address string) (net.Conn, error)

DialContext dial context with dialer WARNING: this can leak a goroutine for as long as the underlying Dialer implementation takes to timeout A Conn returned from a successful Dial after the context has been cancelled will be immediately closed.

func IPv4

func IPv4(v uint32) net.IP

IPv4 数值转换为net.IP

func IsDomain

func IsDomain(host string) bool

IsDomain 是否是域名,只检查host或ip,不可带port,否则会误判

func IsIntranet

func IsIntranet(host string) bool

IsIntranet is intranet network,if host is domain,it will looks up host using the local resolver. net.LookupIP may cause deadlock in windows see https://github.com/golang/go/issues/24178 局域网IP段:

A类: 10.0.0.0~10.255.255.255
B类: 172.16.0.0~172.31.255.255
C类: 192.168.0.0~192.168.255.255

func JoinHostPort

func JoinHostPort(host string, port uint16) string

JoinHostPort combines host and port into a network address of the form "host:port". If host contains a colon, as found in literal IPv6 addresses, then JoinHostPort returns "[host]:port".

See func Dial for a description of the host and port parameters.

func Listen

func Listen(network string, addr string, afterChains ...AdornConn) (net.Listener, error)

Listen announces on the local network address and afterChains

func ListenWith

func ListenWith(network string, addr string, base AdornConn, afterChains ...AdornConn) (net.Listener, error)

ListenWith announces on the local network address , base afterChains

func NewListener

func NewListener(inner net.Listener, base AdornConn, afterChains ...AdornConn) net.Listener

NewListener new listener

func ParseNumeric

func ParseNumeric(s string) (uint32, error)

ParseNumeric 点分十进制字符串转换数值

func SplitHostPort

func SplitHostPort(addr string) (string, uint16, error)

SplitHostPort splits a network address of the form "host:port", "host%zone:port", "[host]:port" or "[host%zone]:port" into host or host%zone and port.

A literal IPv6 address in hostport must be enclosed in square brackets, as in "[::1]:80", "[::1%lo0]:80".

See func Dial for a description of the hostport parameter, and host and port results.

func ToNumeric

func ToNumeric(p net.IP) (uint32, error)

ToNumeric net.IP转换为数值

Types

type AdornConn

type AdornConn func(conn net.Conn) net.Conn

AdornConn defines the conn decorate.

type AdornConnsChain

type AdornConnsChain []AdornConn

AdornConnsChain defines a adornConn array. NOTE: 在conn read或write调用过程是在链上从后往前执行的,(类似栈,先进后执行,后进先执行),

所以统计类的应放在链头,也就是AfterChains的第一个,最靠近出口

type Client

type Client struct {
	Timeout          time.Duration   // timeout for dial
	BaseAdorn        AdornConn       // base adorn conn
	AfterAdornChains AdornConnsChain // chains after base
	Forward          Dialer          // if set it will use forward.
}

Client tcp dialer

func (*Client) Dial

func (sf *Client) Dial(network, addr string) (net.Conn, error)

Dial connects to the address on the named network.

func (*Client) DialContext

func (sf *Client) DialContext(ctx context.Context, network, addr string) (net.Conn, error)

DialContext connects to the address on the named network using the provided context.

type ContextDialer

type ContextDialer interface {
	DialContext(ctx context.Context, network, address string) (net.Conn, error)
}

ContextDialer A ContextDialer dials using a context.

type Dialer

type Dialer interface {
	Dial(network, address string) (net.Conn, error)
}

Dialer A Dialer is a means to establish a connection.
