Decompress

O middleware Decompress descomprime o body do request HTTP quando o header Content-Encoding está definido como gzip.

Todo o middleware principal fica no pacote middleware:

import "github.com/labstack/echo/v5/middleware"

Uso

e.Use(middleware.Decompress())

Configuração customizada

e := echo.New()
e.Use(middleware.DecompressWithConfig(middleware.DecompressConfig{
  Skipper: middleware.DefaultSkipper,
}))

Configuração

type DecompressConfig struct {
  // Skipper defines a function to skip middleware.
  Skipper Skipper

  // GzipDecompressPool provides the sync.Pool used to create and store gzip readers.
  GzipDecompressPool Decompressor

  // MaxDecompressedSize limits the maximum size of the decompressed request body in
  // bytes. If the decompressed body exceeds this limit, the middleware returns an
  // HTTP 413 error. This prevents zip-bomb attacks where a small compressed payload
  // decompresses to a huge size.
  // Default: 100 * MB (104,857,600 bytes). Set to -1 to disable limits (not recommended).
  MaxDecompressedSize int64
}

Configuração padrão

// Effective defaults applied when fields are left unset.
DecompressConfig{
  Skipper:             DefaultSkipper,
  GzipDecompressPool:  &DefaultGzipDecompressPool{},
  MaxDecompressedSize: 100 * MB,
}
