README ¶

Request decompression middleware

decompress expands Content-Encoding: gzip request bodies with both an absolute output limit and an expansion-ratio limit.

app.Post("/ingest",
    decompress.New(decompress.Config{
        MaxSize: 8 << 20,
        MaxExpansionRatio: 50,
    }),
    ingest,
)

The compressed wire body remains subject to the server's MaxRequestBodySize; MaxSize separately bounds the decoded body.

var (
	ErrTooLarge         = errors.New("decompress: expanded body exceeds limit")
	ErrExpansionRatio   = errors.New("decompress: expansion ratio exceeds limit")
	ErrUnsupported      = errors.New("decompress: unsupported content encoding")

)

Functions ¶

func DecodeGzip ¶

func DecodeGzip(src []byte, maxSize, maxRatio int) ([]byte, error)

DecodeGzip expands src with both an absolute limit and an expansion-ratio limit. The ratio check makes small, highly compressible bombs fail early.

func New ¶

func New(config ...Config) fh.HandlerFunc

Types ¶

type Config ¶

type Config struct {
	MaxSize           int
	MaxExpansionRatio int
	Next              func(fh.Ctx) bool
}
