## 実行

/// info | "情報"

まず<a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>をインストールします。

例えば、`pip install python-multipart`。

これは、**OAuth2**が `ユーザー名` や `パスワード` を送信するために、「フォームデータ」を使うからです。

例を実行します:

<div class="termy">

```console
$ uvicorn main:app --reload

 *   // The resource was cached! Show it.
 * } else {
 *   // The resource was not cached.
 * }
 * ```
 *
 * This technique works even better in situations where a stale response is better than no response.
 * To permit stale cached responses, use the `max-stale` directive with the maximum staleness in
 * seconds:
 *
 * ```java
 * Request request = new Request.Builder()
 *     .cacheControl(new CacheControl.Builder()

	// CustomLabels are labels to add to the generated webhook.
	CustomLabels map[string]string
	// UserManaged indicates whether the revision tag is user managed.
	// If true, the revision tag will not be affected by the installer.
	UserManaged bool
}

// Generate generates the manifests for a revision tag pointed the given revision.
func Generate(ctx context.Context, client kube.Client, opts *GenerateOptions, istioNS string) (string, error) {

*----+------+------+

*----+------+------+

That when called, return instances of classes of the same name.

So, you import `Query`, which is a function. And when you call it, it returns an instance of a class also named `Query`.

These functions are there (instead of just using the classes directly) so that your editor doesn't mark errors about their types.

type QueueStore[_ any] struct {
	sync.RWMutex
	entryLimit uint64
	directory  string
	fileExt    string

	entries map[string]int64 // key -> modtime as unix nano
}

// NewQueueStore - Creates an instance for QueueStore.
func NewQueueStore[I any](directory string, limit uint64, ext string) *QueueStore[I] {
	if limit == 0 {
		limit = defaultLimit
	}

	if ext == "" {
		ext = defaultExt
	}

そして、Gunicorn互換の**Uvicornワーカー**クラスが、FastAPIが使えるように、Gunicornから送られてきたデータをASGI標準に変換する役割を担います。

## GunicornとUvicornをインストールする

<div class="termy">

```console
$ pip install "uvicorn[standard]" gunicorn

---> 100%
```

</div>

これによりUvicornと（高性能を得るための）標準（`standard`）の追加パッケージとGunicornの両方がインストールされます。

## UvicornのワーカーとともにGunicornを実行する

Gunicornを以下のように起動させることができます:

要使其工作，您需要执行 `pip install python-dotenv`。

### `.env` 文件

您可以使用以下内容创建一个名为 `.env` 的文件：

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
