Она спроектирована так, чтобы быть очень простой в использовании и облегчать любому разработчику интеграцию других компонентов с **FastAPI**.

## Что такое инъекция зависимостей («Dependency Injection») { #what-is-dependency-injection }

В программировании **«Dependency Injection»** означает, что у вашего кода (в данном случае у ваших *функций обработки пути*) есть способ объявить вещи, которые требуются для его работы и использования: «зависимости».

It is designed to be very simple to use, and to make it very easy for any developer to integrate other components with **FastAPI**.

## What is "Dependency Injection" { #what-is-dependency-injection }

Es ist so konzipiert, sehr einfach zu verwenden zu sein und es jedem Entwickler sehr leicht zu machen, andere Komponenten mit **FastAPI** zu integrieren.

## Was ist „Dependency Injection“ { #what-is-dependency-injection }

## Code size { #code-size }

This example might seem verbose. Keep in mind that we are mixing security, data models, utility functions and *path operations* in the same file.

But here's the key point.

The security and dependency injection stuff is written once.

## Codegröße { #code-size }

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.

Each process, or "runtime", applies different constraints to the code that runs in that process.
For example, each process has different supported JVMs and a different set of services available for dependency injection.
While a lot of Gradle source code runs only in the Gradle daemon, not all of it does so.
When working on some source code it is important to be aware of the runtimes in which it will run, so that you don't break these constraints.
