GO 网络模块

net.Conn 网络连接 net.Dial("TCP/UDP/IP", "43.225.158.198:80")

面向字节流的网络连接。

Read(b []byte) (n int, err error)
Write(b []byte) (n int, err error)
Close() error
LocalAddr() Addr
RemoteAddr() Addr
SetDeadline(t time.Time) error
SetReadDeadline(t time.Time) error
SetWriteDeadline(t time.Time) error

net.PacketConn

面向消息的连接。

ReadFrom(p []byte) (n int, addr Addr, err error)
WriteTo(p []byte, addr Addr) (n int, err error)
Close() error
LocalAddr() Addr
SetDeadline(t time.Time) error
SetReadDeadline(t time.Time) error
SetWriteDeadline(t time.Time) error

net.UDPConn <==> net.Conn + net.PacketConn net.ListenUDP("udp", "8080")

UDP 网络连接

Read(b []byte) (n int, err error)
Write(b []byte) (n int, err error)
ReadFrom(p []byte) (n int, addr Addr, err error)
WriteTo(p []byte, addr Addr) (n int, err error)
Close() error
LocalAddr() Addr
RemoteAddr() Addr
SetDeadline(t time.Time) error
SetReadDeadline(t time.Time) error
SetWriteDeadline(t time.Time) error

net.Listener 网络服务器，监听一个地址 net.Listen("tcp", ":8080")

Accept() (Conn, error)
Close() error
Addr() Addr

net.Addr 网络地址

Network() string
String() string

net.Dialer 拨号器

包含连接相关的配置。
