transfer

传输层协议库。

• ReadSocket：从Socket中读取指定长度数据。
• ReadSocketWithMaxLength：从Socket中读取指定长度的数据，校验最大长度是否有效。
• IsLAN：判断是否是局域网IP地址。
• CheckIpRange：判断IP是否位于区间内。
• 字节流大端序：ReadBigEndian、WriteBigEndian
• 字节流小端序：ReadLittleEndian、WriteLittleEndian

Functions

func CheckIpRange

func CheckIpRange(
	curIp net.IP,
	fromIp net.IP,
	toIp net.IP,
) bool

检查IP是否位于区间中

func IsLAN

func IsLAN(addr string) bool

检查是否为局域网地址

func ReadBigEndian

func ReadBigEndian(content []byte, target interface{}) (err error)

按大端序解析[]byte到结构体

func ReadLittleEndian

func ReadLittleEndian(content []byte, target interface{}) (err error)

按小端序解析[]byte到结构体

func ReadSocket

func ReadSocket(
	conn net.Conn,
	length uint32,
) (buf []byte, err error)

从连接中读取数据，不判断最大长度

func ReadSocketWithMaxLength

func ReadSocketWithMaxLength(
	conn net.Conn,
	length uint32,
	maxLength uint32,
) (buf []byte, err error)

从连接中读取数据，判断最大长度

func WriteBigEndian

func WriteBigEndian(content interface{}) (result []byte, err error)

将数据转换为大端序

func WriteLittleEndian

func WriteLittleEndian(content interface{}) (result []byte, err error)

将数据转换为小端序
