## Manejo de codificaciones personalizadas de request body { #handling-custom-request-body-encodings }

Veamos cómo hacer uso de una subclase personalizada de `Request` para descomprimir requests gzip.

Y una subclase de `APIRoute` para usar esa clase de request personalizada.

    }

    Request compressedRequest = originalRequest.newBuilder()
        .header("Content-Encoding", "gzip")
        .method(originalRequest.method(), gzip(originalRequest.body()))
        .build();
    return chain.proceed(compressedRequest);
  }

  private RequestBody gzip(final RequestBody body) {
    return new RequestBody() {
      @Override public MediaType contentType() {

import gzip
from typing import Annotated, Callable

from fastapi import Body, FastAPI, Request, Response
from fastapi.routing import APIRoute


class GzipRequest(Request):
    async def body(self) -> bytes:
        if not hasattr(self, "_body"):
            body = await super().body()
            if "gzip" in self.headers.getlist("Content-Encoding"):
                body = gzip.decompress(body)
            self._body = body

## `GZipMiddleware` { #gzipmiddleware }

Обрабатывает GZip‑ответы для любых запросов, которые включают `"gzip"` в заголовке `Accept-Encoding`.

Это middleware обрабатывает как обычные, так и потоковые ответы.

{* ../../docs_src/advanced_middleware/tutorial003_py39.py hl[2,6] *}

Поддерживаются следующие аргументы:

null-long-match.wb.expect-noinput", "src/compress/flate/token.go", "src/compress/flate/writer_test.go", "src/compress/gzip/", "src/compress/gzip/example_test.go", "src/compress/gzip/gunzip.go", "src/compress/gzip/gunzip_test.go", "src/compress/gzip/gzip.go", "src/compress/gzip/gzip_test.go", "src/compress/gzip/issue14937_test.go", "src/compress/gzip/testdata/", "src/compress/gzip/testdata/issue6550.gz.base64", "src/compress/lzw/", "src/compress/lzw/reader.go", "src/compress/lzw/reader_test.go", ...

## `GZipMiddleware` { #gzipmiddleware }

Handles GZip responses for any request that includes `"gzip"` in the `Accept-Encoding` header.

The middleware will handle both standard and streaming responses.

{* ../../docs_src/advanced_middleware/tutorial003_py39.py hl[2,6] *}

The following arguments are supported:

* `minimum_size` - Do not GZip responses that are smaller than this minimum size in bytes. Defaults to `500`.

        .post("This is the original message".toRequestBody())
        .gzip()
        .gzip()
        .build()
    }.also {
      assertThat(it).hasMessage("Content-Encoding already set: gzip")
    }
  }

  @Test
  fun curlGet() {
    val request =
      Request
        .Builder()
        .url("https://example.com")
        .header("Authorization", "Bearer abc123")
        .build()

* Descomprimir corpos de requisição comprimidos com gzip.

## Manipulando codificações de corpo de requisição personalizadas { #handling-custom-request-body-encodings }

Vamos ver como usar uma subclasse personalizada de `Request` para descomprimir requisições gzip.

E uma subclasse de `APIRoute` para usar essa classe de requisição personalizada.

* Decompressing gzip-compressed request bodies.
* Automatically logging all request bodies.

## Handling custom request body encodings { #handling-custom-request-body-encodings }

Let's see how to make use of a custom `Request` subclass to decompress gzip requests.

And an `APIRoute` subclass to use that custom request class.

- UTF-8 is the only encoding type the Select API supports.
- GZIP or BZIP2 - CSV and JSON files can be compressed using GZIP, BZIP2, [ZSTD](https://facebook.github.io/zstd/), and streaming formats of [LZ4](https://lz4.github.io/lz4/), [S2](https://github.com/klauspost/compress/tree/master/s2#s2-compression) and [SNAPPY](http://google.github.io/snappy/).
