Artık şunları yapan bir API oluşturdunuz:

* `/` ve `/items/{item_id}` _path_'lerinde HTTP request'leri alır.
* Her iki _path_ de `GET` operasyonlarını (HTTP _method_'ları olarak da bilinir) kabul eder.
* `/items/{item_id}` _path_'i, `int` olması gereken `item_id` adlı bir _path parameter_'a sahiptir.
* `/items/{item_id}` _path_'i, opsiyonel `str` bir _query parameter_ olan `q`'ya sahiptir.

```JSON
{"item_id": 5, "q": "somequery"}
```

Ya creaste una API que:

* Recibe requests HTTP en los _paths_ `/` y `/items/{item_id}`.
* Ambos _paths_ toman _operaciones_ `GET` (también conocidas como métodos HTTP).
* El _path_ `/items/{item_id}` tiene un _parámetro de path_ `item_id` que debe ser un `int`.
* El _path_ `/items/{item_id}` tiene un _parámetro de query_ `q` opcional que es un `str`.

{"item_id": 5, "q": "somequery"}
```

Você acabou de criar uma API que:

* Recebe requisições HTTP nos _paths_ `/` e `/items/{item_id}`.
* Ambos _paths_ fazem operações `GET` (também conhecido como _métodos_ HTTP).
* O _path_ `/items/{item_id}` tem um _parâmetro de path_ `item_id` que deve ser um `int`.
* O _path_ `/items/{item_id}` tem um _parâmetro query_ `q` `str` opcional.

{"item_id": 5, "q": "somequery"}
```

You already created an API that:

* Receives HTTP requests in the _paths_ `/` and `/items/{item_id}`.
* Both _paths_ take `GET` operations (also known as HTTP _methods_).
* The _path_ `/items/{item_id}` has a _path parameter_ `item_id` that should be an `int`.
* The _path_ `/items/{item_id}` has an optional `str` _query parameter_ `q`.

Sonra alt uygulamanın dokümanlarını [http://127.0.0.1:8000/subapi/docs](http://127.0.0.1:8000/subapi/docs) adresinden açın.

Alt uygulama için otomatik API dokümanlarını göreceksiniz; yalnızca onun kendi _path operation_’larını içerir ve hepsi doğru alt-path öneki `/subapi` altında yer alır:

"Mounting" means adding a completely "independent" application in a specific path, that then takes care of handling everything under that path, with the _path operations_ declared in that sub-application.

### Top-level application { #top-level-application }

First, create the main, top-level, **FastAPI** application, and its *path operations*:

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[3, 6:8] *}

                    String path = htmlNext.getRoutingPath();
                    assertFalse("Duplicate path found: " + path + " in field " + field.getName(), paths.contains(path));
                    paths.add(path);
                }
            }
        }
        assertTrue("Should have unique paths", paths.size() > 0);
    }

    @Test

In Ihrem Client erhalten Sie eine JSON-Response, wie etwa:

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

## Pfad-Parameter, die Pfade enthalten { #path-parameters-containing-paths }

Angenommen, Sie haben eine *Pfadoperation* mit einem Pfad `/files/{file_path}`.

Aber `file_path` soll selbst einen *Pfad* enthalten, etwa `home/johndoe/myfile.txt`.
