## Change Default Swagger UI Parameters { #change-default-swagger-ui-parameters }

FastAPI includes some default configuration parameters appropriate for most of the use cases.

It includes these default configurations:

{* ../../fastapi/openapi/docs.py ln[9:24] hl[18:24] *}

* Add support for `UploadFile` in `File` parameter annotations.
    * This includes a file-like interface.
    * Here's the updated documentation for declaring [`File` parameters with `UploadFile`](https://fastapi.tiangolo.com/tutorial/request-files/#file-parameters-with-uploadfile).

        // We verify the object was created successfully instead
        assertNotNull(trans2GetDfsReferral);

        // Verify that request buffer was created with correct parameters
        Field requestField = Trans2GetDfsReferral.class.getDeclaredField("request");
        requestField.setAccessible(true);

You can think of `APIRouter` as a "mini `FastAPI`" class.

All the same options are supported.

All the same `parameters`, `responses`, `dependencies`, `tags`, etc.

/// tip

In this example, the variable is called `router`, but you can name it however you want.

///

   * Tests equality of {@link Hashing#goodFastHash} instances. This test must be separate from
   * {@link #testSeededHashFunctionEquals} because the parameter to {@code goodFastHash} is a size,
   * not a seed, and because that size is rounded up. Thus, {@code goodFastHash} instances with
   * different parameters can be equal. That fact is a problem for {@code
   * testSeededHashFunctionEquals}.

# パスパラメータ { #path-parameters }

Pythonのformat文字列と同様のシンタックスで「パスパラメータ」や「パス変数」を宣言できます:

{* ../../docs_src/path_params/tutorial001_py310.py hl[6:7] *}

パスパラメータ `item_id` の値は、引数 `item_id` として関数に渡されます。

したがって、この例を実行して [http://127.0.0.1:8000/items/foo](http://127.0.0.1:8000/items/foo) にアクセスすると、次のレスポンスが表示されます。

```JSON
{"item_id":"foo"}
```

## 型付きパスパラメータ { #path-parameters-with-types }

標準のPythonの型アノテーションを使用して、関数内のパスパラメータの型を宣言できます:
