net.Listen()

監聽某個tcp,utp,id prot

net.Dial()

連接到某個tcp,utp,id的prot

Conn

透過net.Dial建立跟service連線後會得到一個Conn，該interface實作了兩個func

// 讀取service傳遞過來的資料
Read(b []byte) (n int, err error)

// 發送資料到service
Write(b []byte) (n int, err error)

listener.Accept()

等待同意Client的連線

net.ResolveTCPAddr

將ip:prot解析成Tcp Addr，該interface實作了兩個func

// 是tcp or utp
Network() string

// ip
String() string
