Ancak `Depends` yerine `Security` kullanınca **FastAPI**, security scope'larının tanımlanabileceğini bilir, bunları içeride kullanır ve API'yi OpenAPI ile dokümante eder.

Fakat `fastapi` içinden `Query`, `Path`, `Depends`, `Security` vb. import ettiğiniz şeyler, aslında özel sınıflar döndüren fonksiyonlardır.

///

## `SecurityScopes` kullanımı { #use-securityscopes }

### Contenedores con Múltiples Procesos y Casos Especiales { #containers-with-multiple-processes-and-special-cases }

Por supuesto, hay **casos especiales** donde podrías querer tener **un contenedor** con varios **worker processes de Uvicorn** dentro.

En esos casos, puedes usar la opción de línea de comandos `--workers` para establecer el número de workers que deseas ejecutar:

Но используя `Security` вместо `Depends`, **FastAPI** будет знать, что можно объявлять security scopes, использовать их внутри и документировать API в OpenAPI.

Однако когда вы импортируете `Query`, `Path`, `Depends`, `Security` и другие из `fastapi`, это на самом деле функции, возвращающие специальные классы.

* the contents of a file in the disk to be read by the system and given to your program
* the contents your program gave to the system to be written to disk
* a remote API operation
* a database operation to finish
* a database query to return the results

As the execution time is consumed mostly by waiting for <abbr title="Input and Output">I/O</abbr> operations, they call them "I/O bound" operations.
