### Use it { #use-it }

Now you can pass that `oauth2_scheme` in a dependency with `Depends`.

{* ../../docs_src/security/tutorial001_an_py39.py hl[12] *}

This dependency will provide a `str` that is assigned to the parameter `token` of the *path operation function*.

**FastAPI** will know that it can use this dependency to define a "security scheme" in the OpenAPI schema (and the automatic API docs).

## Codegröße

Dieses Beispiel mag ausführlich erscheinen. Bedenken Sie, dass wir Sicherheit, Datenmodelle, Hilfsfunktionen und *Pfadoperationen* in derselben Datei vermischen.

Aber hier ist der entscheidende Punkt.

Der Code für Sicherheit und Dependency Injection wird einmal geschrieben.

  // It's a constant, and we can't use ImmutableMap here without creating a circular dependency.
  @SuppressWarnings("ConstantCaseForConstants")
  private static final Map<Class<?>, Class<?>> PRIMITIVE_TO_WRAPPER_TYPE;

  /** A map from wrapper types to their corresponding primitive types. */
  // It's a constant, and we can't use ImmutableMap here without creating a circular dependency.
  @SuppressWarnings("ConstantCaseForConstants")

# Implantação

A implantação de uma aplicação **FastAPI** é relativamente simples.

Existem várias maneiras para fazer isso, dependendo do seu caso específico e das ferramentas que você utiliza.

import org.apache.maven.api.annotations.Experimental;
import org.apache.maven.api.annotations.Immutable;

/**
 * A {@link Dependency} that has been resolved, i.e. downloaded to the local repository.
 *
 * @since 4.0.0
 */
@Experimental
@Immutable

### Dependency Injection

FastAPI bao gồm một hệ thống <abbr title='cũng biết đến như là "components", "resources", "services", "providers"'><strong>Dependency Injection</strong></abbr> vô cùng dễ sử dụng nhưng vô cùng mạnh mẽ.

* Thậm chí, các dependency có thể có các dependency khác, tạo thành một phân cấp hoặc **"một đồ thị" của các dependency**.
* Tất cả **được xử lí tự động** bởi framework.

# `Response` class

You can declare a parameter in a *path operation function* or dependency to be of type `Response` and then you can set data for the response like headers or cookies.

You can also use it directly to create an instance of it and return it from your *path operations*.

You can import it directly from `fastapi`:

```python
from fastapi import Response
```

	"github.com/minio/minio/internal/logger"
	"github.com/minio/pkg/v3/quick"
)

// FileLogger is introduced to workaround the dependency about logrus
type FileLogger struct {
	Enable   bool   `json:"enable"`
	Filename string `json:"filename"`
}

// ConsoleLogger is introduced to workaround the dependency about logrus
type ConsoleLogger struct {
	Enable bool `json:"enable"`
}
