Functions

func AttachDefenseAgainstDarkArts

func AttachDefenseAgainstDarkArts(e *echo.Echo, maxRequestSize int, timeout time.Duration)

Attach middleware to Echo to prevent slow-loris attacks and DDoS-es by extremely large requests.

func LimitReaderWithErr

func LimitReaderWithErr(r io.ReadCloser, n int64, err error) io.ReadCloser

LimitReader returns a Reader that reads from r but stops with an error after n bytes. The underlying implementation is a *LimitedReaderWithErr.

func NewEchoTargetedHttpClient

func NewEchoTargetedHttpClient(ec *echo.Echo) http.Client

Types

type DirectEchoTransport

type DirectEchoTransport struct {
	Echo *echo.Echo
}

func (*DirectEchoTransport) RoundTrip

func (f *DirectEchoTransport) RoundTrip(req *http.Request) (*http.Response, error)

type LimitedReaderWithErr

type LimitedReaderWithErr struct {
	Reader    io.ReadCloser // underlying reader
	BytesLeft int64         // max bytes remaining
	Error     error         // the error to return in case of too much data
}

A LimitedReaderWithErr reads from Reader but limits the amount of data returned to just BytesLeft bytes. Each call to Read updates BytesLeft to reflect the new amount remaining. Read returns error when BytesLeft <= 0 or when the underlying Reader returns EOF.

func (*LimitedReaderWithErr) Close

func (l *LimitedReaderWithErr) Close() error

func (*LimitedReaderWithErr) Read

func (l *LimitedReaderWithErr) Read(p []byte) (n int, err error)
