     * The imgur client ID for OkHttp recipes. If you're using imgur for anything other than running

// When **no** flags are passed, the behavior is to trace both headers and body,
// gzip the response and throttle the handler via `maxClients`. Each of these
// can be disabled via the corresponding `s3HFlag`.
//
// CAUTION: for requests involving large req/resp bodies ensure to pass the
// `traceHdrsS3HFlag`, otherwise both headers and body will be traced, causing
// high memory usage!

De la misma forma en que usas `Body`, `Query`, etc. con los parámetros de tu *path operation function*, usa `Depends` con un nuevo parámetro:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

Aunque usas `Depends` en los parámetros de tu función de la misma manera que usas `Body`, `Query`, etc., `Depends` funciona un poco diferente.

Le das a `Depends` un solo parámetro.

  @StartStop
  private val server = MockWebServer()

  @AfterEach fun tearDown() {
    httpClient.close()
  }

  @Test fun get() {
    server.enqueue(
      MockResponse
        .Builder()
        .body("hello, Apache HttpClient 5.x")
        .build(),
    )

    val request = HttpGet(server.url("/").toUri())
    request.addHeader("Accept", "text/plain")

    httpClient.execute(request).use { response ->

    assert response.status_code == 422
    assert response.json() == {
        "detail": [
            {
                "type": "string_pattern_mismatch",
                "loc": ["body", "q"],
                "msg": "String should match pattern '^fixedquery$'",
                "input": "nonregexquery",
                "ctx": {"pattern": "^fixedquery$"},
            }
        ]
    }

The same way you use `Body`, `Query`, etc. with your *path operation function* parameters, use `Depends` with a new parameter:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

Although you use `Depends` in the parameters of your function the same way you use `Body`, `Query`, etc, `Depends` works a bit differently.

You only give `Depends` a single parameter.

They will receive an error response telling them that the field `extra` is not allowed:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["body", "extra"],
            "msg": "Extra inputs are not permitted",
            "input": "Mr. Poopybutthole"
        }
    ]
}
```

## Summary { #summary }

So wie auch `Body`, `Query`, usw., verwenden Sie `Depends` mit den Parametern Ihrer *Pfadoperation-Funktion*:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

Obwohl Sie `Depends` in den Parametern Ihrer Funktion genauso verwenden wie `Body`, `Query`, usw., funktioniert `Depends` etwas anders.

Sie übergeben `Depends` nur einen einzigen Parameter.

{* ../../docs_src/request_files/tutorial001_an_py39.py hl[3] *}

## Definir Parámetros `File` { #define-file-parameters }

Crea parámetros de archivo de la misma manera que lo harías para `Body` o `Form`:

{* ../../docs_src/request_files/tutorial001_an_py39.py hl[9] *}

/// info | Información

`File` es una clase que hereda directamente de `Form`.

例如： `pip install python-multipart`。

///

## 导入 `File`

从 `fastapi` 导入 `File` 和 `UploadFile`：

{* ../../docs_src/request_files/tutorial001.py hl[1] *}

## 定义 `File` 参数

创建文件（`File`）参数的方式与 `Body` 和 `Form` 一样：

{* ../../docs_src/request_files/tutorial001.py hl[7] *}

/// info | 说明

`File` 是直接继承自 `Form` 的类。

注意，从 `fastapi` 导入的 `Query`、`Path`、`File` 等项，实际上是返回特定类的函数。
