   *
   * With regular HTTP calls the request always completes sending before the response may begin

   * may be sent after response headers or body bytes have been received.

## Instance'ı dependency olarak kullanma { #use-the-instance-as-a-dependency }

Sonra `Depends(FixedContentQueryChecker)` yerine `Depends(checker)` içinde bu `checker`'ı kullanabiliriz. Çünkü dependency, class'ın kendisi değil, `checker` instance'ıdır.

Ve dependency çözülürken **FastAPI** bu `checker`'ı şöyle çağırır:

```Python
checker(q="somequery")
```

 * them into smaller messages or using HTTP requests instead.

To send data, you should use one of: `POST` (the more common), `PUT`, `DELETE` or `PATCH`.

Sending a body with a `GET` request has an undefined behavior in the specifications, nevertheless, it is supported by FastAPI, only for very complex/extreme use cases.
