## 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。

///

/// tip | 提示

声明文件体必须使用 `File`，否则，FastAPI 会把该参数当作查询参数或请求体（JSON）参数。

///

文件作为「表单数据」上传。

如果把*路径操作函数*参数的类型声明为 `bytes`，**FastAPI** 将以 `bytes` 形式读取和接收文件内容。

   * @param promisedStreamId server-initiated stream ID.  Must be an even number.
   * @param requestHeaders minimally includes `:method`, `:scheme`, `:authority`, and `:path`.

  @Throws(IOException::class)
  fun pushPromise(

    promisedStreamId: Int,

  ) {
    withLock {

        }
    }

    /**

    protected String convertRobotsTxtPatternToRegex(final String path) {
        String newPath = path.replace(".", "\\.").replace("?", "\\?").replace("*", ".*");
        if (newPath.charAt(0) != '/') {

    private static final Logger logger = LogManager.getLogger(TikaExtractor.class);

   * 8`, so the class files from that build can't express nestmates. Thus, when those class files

首先，要关注的是依赖项。

依赖项就是一个函数，且可以使用与*路径操作函数*相同的参数：

{* ../../docs_src/dependencies/tutorial001.py hl[8:11] *}

大功告成。

只用了**2 行**代码。

依赖项函数的形式和结构与*路径操作函数*一样。

因此，可以把依赖项当作没有「装饰器」（即，没有 `@app.get("/some-path")` ）的路径操作函数。

依赖项可以返回各种内容。

本例中的依赖项预期接收如下参数：

* 类型为 `str` 的可选查询参数 `q`
* 类型为 `int` 的可选查询参数 `skip`，默认值是 `0`
* 类型为 `int` 的可选查询参数 `limit`，默认值是 `100`

然后，依赖项函数返回包含这些值的 `dict`。

### 导入 `Depends`

		name    string
		fv      formValues
		expired bool
		wantErr string
	}

	// Test case just contains fields we override from defaultFormVals.
	testCases := []testCase{

			name:    "happy path no errors",
			fv:      defaultFormVals.Clone(),
			wantErr: "",
		},
		{
			name:    "expired policy document",
			fv:      defaultFormVals.Clone(),
			expired: true,
