# 경로 매개변수와 숫자 검증 { #path-parameters-and-numeric-validations }

`Query`를 사용하여 쿼리 매개변수에 더 많은 검증과 메타데이터를 선언하는 방법과 동일하게 `Path`를 사용하여 경로 매개변수에 검증과 메타데이터를 같은 타입으로 선언할 수 있습니다.

## `Path` 임포트 { #import-path }

먼저 `fastapi`에서 `Path`를 임포트하고, `Annotated`도 임포트합니다:

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[1,3] *}

/// info | 정보

FastAPI는 0.95.0 버전에서 `Annotated` 지원을 추가했고(그리고 이를 권장하기 시작했습니다).

# 路径参数和数值校验 { #path-parameters-and-numeric-validations }

与使用 `Query` 为查询参数声明更多的校验和元数据的方式相同，你也可以使用 `Path` 为路径参数声明相同类型的校验和元数据。

## 导入 `Path` { #import-path }

首先，从 `fastapi` 导入 `Path`，并导入 `Annotated`：

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[1,3] *}

/// info | 信息

FastAPI 在 0.95.0 版本添加了对 `Annotated` 的支持（并开始推荐使用它）。

如果你使用的是更旧的版本，尝试使用 `Annotated` 会报错。

type ListMultipartsInfo struct {
	// Together with upload-id-marker, this parameter specifies the multipart upload
	// after which listing should begin.
	KeyMarker string

	// Together with key-marker, specifies the multipart upload after which listing
	// should begin. If key-marker is not specified, the upload-id-marker parameter
	// is ignored.
	UploadIDMarker string

            assertEquals(customLevel, infoLevel.getInt(resp));
        }
    }

        void testReadParametersWireFormat() {
            byte[] buffer = new byte[10];
            int result = response.readParametersWireFormat(buffer, 0, 2);
            assertEquals(2, result);
        }

# `UploadFile` class

You can define *path operation function* parameters to be of the type `UploadFile` to receive files from the request.

You can import it directly from `fastapi`:

```python
from fastapi import UploadFile
```

::: fastapi.UploadFile
    options:
        members:
            - file
            - filename
            - size
            - headers
            - content_type
            - read

public class SearchBody extends BaseSearchDictBody {

    /**
     * Default constructor for SearchBody.
     */
    public SearchBody() {
        super();
    }

# `FastAPI` class

Here's the reference information for the `FastAPI` class, with all its parameters, attributes and methods.

You can import the `FastAPI` class directly from `fastapi`:

```python
from fastapi import FastAPI
```

::: fastapi.FastAPI
    options:
        members:
            - openapi_version
            - webhooks
            - state
            - dependency_overrides
