Functions ¶

This section is empty.

Types ¶

type Error ¶

type Error string

Error represents a SOCKS error

func (Error) Error ¶

func (err Error) Error() string

type Socks5Addr ¶

type Socks5Addr struct {
	Raw     []byte
	AType   int
	Address string
	Port    int
}

Socks5Addr represents a SOCKS address as defined in RFC 1928 section 5.

func NewSSProtocol ¶

func NewSSProtocol(atype, port int, address string) *Socks5Addr

func NewSocks5Addr ¶

func NewSocks5Addr(raw []byte, atype int) *Socks5Addr

func ParseAddr ¶

func ParseAddr(s string) *Socks5Addr

ParseAddr parses the address in string s. Returns nil if failed.

func ReadAddr ¶

func ReadAddr(r io.Reader) (*Socks5Addr, error)

ReadAddr reads just enough bytes from r to get a valid Addr.

func SplitAddr ¶

func SplitAddr(b []byte) (*Socks5Addr, error)

SplitAddr slices a SOCKS address from beginning of b. Returns nil if failed.

func (*Socks5Addr) GetAType ¶

func (s *Socks5Addr) GetAType() int

func (*Socks5Addr) GetAddress ¶

func (s *Socks5Addr) GetAddress() string

func (*Socks5Addr) GetPort ¶

func (s *Socks5Addr) GetPort() int

func (*Socks5Addr) GetRaw ¶

func (ss *Socks5Addr) GetRaw() (raw []byte, err error)

Example ¶

fmt.Printf("%v\n", utils.NewSSProtocol(utils.AtypIPv4, 3306, "127.0.0.1").MustGetRaw())
ss := utils.SplitAddr(utils.NewSSProtocol(utils.AtypIPv4, 3306, "127.0.0.1").MustGetRaw())
if ss == nil {
	fmt.Println("ss is null")
}
fmt.Printf("%v\n", ss.MustGetRaw())

fmt.Printf("%v\n", utils.NewSSProtocol(utils.AtypDomainName, 3306, "baidu.com").MustGetRaw())
ss = utils.SplitAddr(utils.NewSSProtocol(utils.AtypDomainName, 3306, "baidu.com").MustGetRaw())
if ss == nil {
	fmt.Println("ss is null")
}
fmt.Printf("%v\n", ss.MustGetRaw())

Output:

[1 127 0 0 1 12 234]
[1 127 0 0 1 12 234]
[3 9 98 97 105 100 117 46 99 111 109 12 234]
[3 9 98 97 105 100 117 46 99 111 109 12 234]

func (*Socks5Addr) MustGetRaw ¶

func (ss *Socks5Addr) MustGetRaw() []byte

func (*Socks5Addr) String ¶

func (s *Socks5Addr) String() string
