Later, when reading about how to structure bigger applications ([Bigger Applications - Multiple Files](../../tutorial/bigger-applications.md)), possibly with multiple files, you will learn how to declare a single `dependencies` parameter for a group of *path operations*....

        formatType = detectFormatType(request);
        request.setAttribute(API_FORMAT_TYPE, formatType);
        return formatType;
    }

    /**
     * Detects the format type from the request parameters.
     * @param request The HTTP servlet request.
     * @return The detected format type.
     */
    protected FormatType detectFormatType(final HttpServletRequest request) {

    /** The document paths to exclude from search results (pattern-based). */
    @CustomSize(maxKey = "form.admin.max.input.size")
    public String excludedDocPaths;

    /** Additional configuration parameters for the file crawler. */
    @CustomSize(maxKey = "form.admin.max.input.size")
    public String configParameter;

    /** The maximum crawling depth (0 to 2147483647, 0 means unlimited). */
    @Min(value = 0)

     * @throws CIFSException if decompression fails
     */
    byte[] decompress(byte[] compressedData, int algorithm) throws CIFSException;

    /**
     * Decompresses data with offset and length parameters.
     *
     * @param compressedData the compressed data buffer
     * @param offset the offset in the buffer
     * @param length the length of compressed data

```

这是因为上传文件是以「表单数据」发送的。

///

## 导入 `File` { #import-file }

从 `fastapi` 导入 `File` 和 `UploadFile`：

{* ../../docs_src/request_files/tutorial001_an_py310.py hl[3] *}

## 定义 `File` 参数 { #define-file-parameters }

像为 `Body` 或 `Form` 一样创建文件参数：

{* ../../docs_src/request_files/tutorial001_an_py310.py hl[9] *}

/// info | 信息

`File` 是直接继承自 `Form` 的类。

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