}

// URI scheme constants.
const (
	httpScheme  = "http"
	httpsScheme = "https"
)

// nopCharsetConverter is a dummy charset convert which just copies input to output,
// it is used to ignore custom encoding charset in S3 XML body.
func nopCharsetConverter(label string, input io.Reader) (io.Reader, error) {
	return input, nil
}

// xmlDecoder provide decoded value in xml.

    source.append(newPreFilledByteArray(5, 10));

    // The stream reports no bytes... importantly, it doesn't read the byte at index 5 when it
    // should be reading the byte at index 10.
    // We could use a custom InputStream instead to make the read start at index 10, but since this
    // is a racy situation anyway, this behavior seems reasonable.
    assertEquals(-1, in.read());
  }

This could be especially useful during testing, as it's very easy to override a dependency with your own custom settings.

### The config file { #the-config-file }

Coming from the previous example, your `config.py` file could look like:

{* ../../docs_src/settings/app02_an_py310/config.py hl[10] *}

## Utiliser des dépendances avec `yield` et `except` { #dependencies-with-yield-and-except }

FastAPI 0.106.0 이전에는 `yield` 이후에 예외를 발생시키는 것이 불가능했습니다. `yield`가 있는 의존성의 종료 코드는 응답이 전송된 *후에* 실행되었기 때문에, [예외 핸들러](../tutorial/handling-errors.md#install-custom-exception-handlers)가 이미 실행된 뒤였습니다.

이는 주로 백그라운드 태스크 안에서 의존성이 "yield"한 동일한 객체들을 사용할 수 있게 하기 위한 설계였습니다. 백그라운드 태스크가 끝난 뒤에 종료 코드가 실행되었기 때문입니다.

이는 응답이 네트워크를 통해 전달되기를 기다리는 동안 리소스를 점유하지 않기 위한 의도로 FastAPI 0.106.0에서 변경되었습니다.

- Now users can get object info like:

  ```bash
    a. kubectl get pod test-pod -o custom-columns=CONTAINER:.spec.containers[0:3].name
    b. kubectl get pod test-pod -o custom-columns=CONTAINER:.spec.containers[-2:].name
  ```

### 后台任务与带 `yield` 的依赖项（技术细节） { #background-tasks-and-dependencies-with-yield-technical-details }

在 FastAPI 0.106.0 之前，`yield` 之后抛出异常是不可行的，因为带 `yield` 的依赖项中的退出代码会在响应发送之后才执行，此时[异常处理器](../tutorial/handling-errors.md#install-custom-exception-handlers)已经运行完毕。

之所以这样设计，主要是为了允许在后台任务中继续使用依赖项通过 `yield`“产出”的对象，因为退出代码会在后台任务完成之后才执行。

在 FastAPI 0.106.0 中，这一行为被修改，目的是避免在等待响应通过网络传输时一直占用资源。
