* 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):
    return {"item_id": item_id, "q": q}
```

### Dockerfile

现在在相同的project目录创建一个名为`Dockerfile`的文件:

</tr>
</tbody>
</table> </td>
</tr>
<tr>
<td height="15" style="height:15px;padding:0;margin:0;line-height:1px;font-size:1px;"></td>
</tr>
<!-- **END CONTEXT** -->

    // HttpUrl is quite lenient with what characters it accepts. In particular, characters like '{'
    // and '"' are permitted but unlikely to occur in real-world URLs. Unfortunately we can't just
    // lock it down due to URL templating: "http://{env}.{dc}.example.com".
    UrlComponentEncodingTester.newInstance()
      .nonPrintableAscii(Encoding.FORBIDDEN)

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

対応するFastAPIのパスオペレーションはこのようになります:

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

 `requests.get(...)` と`@app.get(...)` には類似点が見受けられます。

/// check | "**FastAPI**へ与えたインスピレーション"

* シンプルで直感的なAPIを持っている点。
* HTTPメソッド名を直接利用し、単純で直感的である。
* 適切なデフォルト値を持ちつつ、強力なカスタマイズ性を持っている。

///

* 다음과 같은 `main.py`을 생성합니다:

```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}
```

### 도커파일

이제 같은 프로젝트 디렉터리에 다음과 같은 파일 `Dockerfile`을 생성합니다:

        app = FastAPI()
        router = APIRouter()

        @router.head("/items/", status_code=204)
        def get_items_headers(response: Response):
            response.headers["X-Cat-Dog"] = "Alone in the world"

        app.include_router(router)
        ```
        """
        return self.api_route(
            path=path,
            response_model=response_model,
            status_code=status_code,

* `main.py` ファイルを作成します：

```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

同じプロジェクト・ディレクトリに`Dockerfile`というファイルを作成します：

interpreted_string_lit = `"` { unicode_value | byte_value } `"` .
</pre>

<pre>
`abc`                // same as "abc"
`\n
\n`                  // same as "\\n\n\\n"
"\n"
"\""                 // same as `"`
"Hello, world!\n"
"日本語"
"\u65e5本\U00008a9e"
"\xff\u00FF"
"\uD800"             // illegal: surrogate half
"\U00110000"         // illegal: invalid Unicode code point
</pre>

<p>

  
  This is currently an alpha-level feature and while it probably will not
  eat your data, it may nibble at it a bit. (It passes e2e testing but has
  not yet seen real-world use.)
  
  At this point it should be functionally mostly identical to the iptables
  mode, except that it does not (and will not) support Service NodePorts on
