response = requests.get("http://example.com/some/url")
```

Die entsprechende *Pfadoperation* der FastAPI-API könnte wie folgt aussehen:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

Sehen Sie sich die Ähnlichkeiten in `requests.get(...)` und `@app.get(...)` an.

        byte[] plaintext = "Hello, SMB3 Encryption!".getBytes();

        // When - Encrypt
        byte[] encrypted = context.encryptMessage(plaintext, sessionId);

En contrepartie l'API _des opérations de chemin_ de FastAPI pourrait ressembler à ceci :

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

Notez les similitudes entre `requests.get(...)` et `@app.get(...)`.

* Erstellen Sie eine `main.py`-Datei mit:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


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


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

## 프로그램 실행

가상 환경을 활성화한 후에는 프로그램을 실행할 수 있습니다. 이때 해당 가상 환경에 설치된 Python과 패키지들이 사용됩니다.

<div class="termy">

```console
$ python main.py

Hello World
```

</div>

## 에디터 설정

에디터를 사용할 경우, 앞서 만든 가상 환경을 사용하도록 설정하는 것이 좋습니다. (대부분의 에디터는 자동으로 감지하기도 합니다.)
이렇게 하면 자동 완성 기능이나 코드 내 오류 표시 기능을 제대로 사용할 수 있습니다.

예시:

* Crea un archivo `main.py` con:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


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


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

### Dockerfile { #dockerfile }

* Crie um arquivo `main.py` com:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


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


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

### Dockerfile { #dockerfile }

        // Write content to file
        try (OutputStream out = file.openOutputStream(false)) {
            out.write(testContent.getBytes("UTF-8"));
        }

    // attempt to delete the file. Do not explicitly close the cache here so the entry is left as
    // incomplete.
    val creator = cache.edit("k1")!!
    creator.newSink(0).buffer().use {
      it.writeUtf8("Hello")
    }

    // Simulate a severe Filesystem failure on the first initialization.
    filesystem.setFaultyDelete(cacheDir / "k1.0.tmp", true)
    filesystem.setFaultyDelete(cacheDir, true)
    cache =

* 创建一个 `main.py` 文件：



```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


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


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