**FastAPI**, request içindeki **headers** bölümünden **her alan** için veriyi **çıkarır** ve size tanımladığınız Pydantic model örneğini verir.

Gerekli header'ları `/docs` altındaki doküman arayüzünde görebilirsiniz:

## Code Conventions

### Class Structure

- **Utility classes**: `abstract` class + `protected` constructor

### Preferred translations / glossary

- Should avoid using simplified Chinese characters and terms. Always examine if the translation can be easily comprehended by the Traditional Chinese readers.
- For some Python-specific terms like "pickle", "list", "dict" etc, we don't have to translate them.
- Use the following preferred translations when they apply in documentation prose:

- request (HTTP): 請求

type Type interface {
	fmt.Stringer

	IsRequested(http.Header) bool
	IsEncrypted(map[string]string) bool
}

// IsRequested returns true and the SSE Type if the HTTP headers
// indicate that some form server-side encryption is requested.
//
// If no SSE headers are present then IsRequested returns false
// and no Type.
func IsRequested(h http.Header) (Type, bool) {
	switch {
	case S3.IsRequested(h):
		return S3, true
