Использовать его очень просто. Например, чтобы выполнить запрос `GET`, Вы бы написали:

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

Противоположная *операция пути* в FastAPI может выглядеть следующим образом:

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

Глядите, как похоже `requests.get(...)` и `@app.get(...)`.

Kullanım şekli oldukça basit. Örneğin bir `GET` isteği yapmak için aşağıdaki yeterli:

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

Bunun FastAPI'deki API <abbr title="Yol İşlemi: Path Operation">*yol işlemi*</abbr> şöyle görünür:

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

        serverList.add(server1);
        serverList.add(server2);

        // Then

        assertEquals("SERVER1", serverList.get(0).oemDomainName);
        assertEquals("SERVER2", serverList.get(1).oemDomainName);
