For those cases, you can use a `Response` parameter.

## Use a `Response` parameter { #use-a-response-parameter }

You can declare a parameter of type `Response` in your *path operation function* (as you can do for cookies and headers).

And then you can set the `status_code` in that *temporal* response object.

{* ../../docs_src/response_change_status_code/tutorial001_py310.py hl[1,9,12] *}

   * equivalent to that of calling {@code put(k, v)} on this map once for each mapping from key
   * {@code k} to value {@code v} in the specified map. The behavior of this operation is undefined
   * if the specified map is modified while the operation is in progress.
   *
   * @since 12.0
   */
  void putAll(Map<? extends K, ? extends V> m);

  /** Discards any cached value for key {@code key}. */

FastAPI transmettra chaque bloc de données à la `StreamingResponse` tel quel ; il n'essaiera pas de le convertir en JSON ni autre chose similaire.

### Fonctions de chemin d'accès non async { #non-async-path-operation-functions }

Vous pouvez également utiliser des fonctions `def` classiques (sans `async`), et utiliser `yield` de la même manière.

# Command Line

Usage:

	go tool asm [flags] file

The specified file must be a Go assembly file.
The same assembler is used for all target operating systems and architectures.
The GOOS and GOARCH environment variables set the desired target.

Flags:

	-D name[=value]
		Predefine symbol name with an optional simple value.

檔案與表單欄位會作為表單資料上傳，而你將能接收到這些檔案與欄位。

你也可以將部分檔案宣告為 `bytes`，另一些宣告為 `UploadFile`。

/// warning

你可以在一個路徑操作 (path operation) 中宣告多個 `File` 與 `Form` 參數，但不能同時再宣告預期以 JSON 接收的 `Body` 欄位，因為該請求的本文會使用 `multipart/form-data` 而非 `application/json` 進行編碼。

這不是 **FastAPI** 的限制，這是 HTTP 通訊協定本身的規範。
