Types ¶

type Conn ¶

type Conn struct {
	net.Conn
	// contains filtered or unexported fields
}

Conn is server-side connection which could sniff info.

func (*Conn) Read ¶

func (c *Conn) Read(p []byte) (n int, err error)

WARNING: data read by NormalReader can't be read from RewindReader again.

func (*Conn) SniffedInfo ¶

func (c *Conn) SniffedInfo() *Info

SniffedInfo returns sniffed info.

type Err ¶

type Err struct {
	// contains filtered or unexported fields
}

func (*Err) Error ¶

func (se *Err) Error() string

type Info ¶

type Info struct {
	Network     string // listening network
	Addr        string // listen address
	Usage       Usage
	UsageExt    string
	Protocols   []string // "http1", "socks5", TODO "SMux", "http2", "websocket", "grpc"...
	HTTP1Req    *http.Request
	HTTP2Fields [][2]string
	Reasons     map[string]string
}

Info is sniffed info.

type Listener ¶

type Listener struct {
	// contains filtered or unexported fields
}

Listener is a multiple networks / ports / protocols listener.

func NewListener ¶

func NewListener() *Listener

NewListener creates new Listener.

func (*Listener) Accept ¶

func (ml *Listener) Accept() (net.Conn, error)

Accept waits for and returns the next connection to the listener.

func (*Listener) AddListen ¶

AddListen add new listen address.

func (*Listener) AddListener ¶

func (ml *Listener) AddListener(rawLn net.Listener, matchers ...Matcher) error

AddListener add new listener.

func (*Listener) Addr ¶

func (ml *Listener) Addr() []string

Addr returns all the listener's network address.

func (*Listener) Close ¶

func (ml *Listener) Close() error

Close closes all the listeners. Any blocked 'Accept' operations will be unblocked and return errors.

func (*Listener) CloseOne ¶

func (ml *Listener) CloseOne(network, addr string) error

CloseOne closes one listener.

type Matcher ¶

type Matcher = func(r io.Reader, out *Info) (toDelBytes int, err error)

Matcher is match method implement.
