from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float
    is_offer: bool = None


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: str = None):
    return {"item_id": item_id, "q": q}


@app.put("/items/{item_id}")

## **FastAPI** compatibility

The simplicity of the dependency injection system makes **FastAPI** compatible with:

* all the relational databases
* NoSQL databases
* external packages
* external APIs
* authentication and authorization systems
* API usage monitoring systems
* response data injection systems
* etc.

## Simple and Powerful

Als Nächstes würden Sie den Server ausführen und die Konfigurationen als Umgebungsvariablen übergeben. Sie könnten beispielsweise `ADMIN_EMAIL` und `APP_NAME` festlegen mit:

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

}
```

Nachdem Sie das NPM-Skript `generate-client` dort stehen haben, können Sie es ausführen mit:

<div class="termy">

```console
$ npm run generate-client

frontend-app@1.0.0 generate-client /home/user/code/frontend-app
> openapi-ts --input http://localhost:8000/openapi.json --output ./src/client --client axios
```

</div>

```Python
results = await some_library()
```

O zaman *path operasyon fonksiyonunu* `async def` ile tanımlayın örneğin:

```Python hl_lines="2"
@app.get('/')
async def read_results():
    results = await some_library()
    return results
```

!!! note "Not"
    Sadece `async def` ile tanımlanan fonksiyonlar içinde `await` kullanabilirsiniz.

                    <mxGeometry x="895" y="650" width="300" height="100" as="geometry"/>...

  offline mode, and then test to see if the file-based basedir for an artifact
  repository works...if it doesn't work, we can mark that repository offline...

  OTOH, all offline-mode checks can probably be run from Wagon-based APIs.

** Maven-SCM

  In all but trivial examples, SCM operations cannot complete without
  having access to the versioning server. Therefore, it is assumed that

  /** Returns true if this cookie should be limited to only HTTPS requests. */
  @get:JvmName("secure") val secure: Boolean,
  /**
   * Returns true if this cookie should be limited to only HTTP APIs. In web browsers this prevents
   * the cookie from being accessible to scripts.
   */
  @get:JvmName("httpOnly") val httpOnly: Boolean,
  /**
   * Returns true if this cookie does not expire at the end of the current session.

    ```Python hl_lines="8-11"
    {!> ../../../docs_src/dependencies/tutorial001.py!}
    ```

이게 다입니다.

**단 두 줄입니다**.

그리고, 이 함수는 여러분의 모든 *경로 작동 함수*가 가지고 있는 것과 같은 형태와 구조를 가지고 있습니다.

여러분은 이를 "데코레이터"가 없는 (`@app.get("/some-path")`가 없는) *경로 작동 함수*라고 생각할 수 있습니다.

그리고 여러분이 원하는 무엇이든 반환할 수 있습니다.

이 경우, 이 의존성은 다음과 같은 경우를 기대합니다:

* 선택적인 쿼리 매개변수 `q`, `str`을 자료형으로 가집니다.
* 선택적인 쿼리 매개변수 `skip`, `int`를 자료형으로 가지며 기본 값은 `0`입니다.

RUN pip install fastapi uvicorn

EXPOSE 80

COPY ./app /app

CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "80"]
```

### Crie o código **FastAPI**

* Crie um diretório `app` e entre nele.
* Crie um arquivo `main.py` com:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}
