### 使用 `settings` { #use-the-settings }

然后你可以在应用中使用新的 `settings` 对象：

{* ../../docs_src/settings/tutorial001_py310.py hl[18:20] *}

### 运行服务器 { #run-the-server }

接下来，运行服务器，并把配置作为环境变量传入，例如你可以设置 `ADMIN_EMAIL` 和 `APP_NAME`：

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

			if err != nil {
				info.Disks = getOfflineDisks(client.host.String(), globalEndpoints)
			}
			replies[idx] = info
		}(client, i)
	}
	wg.Wait()

	// Add local to this server.
	replies = append(replies, objLayer.LocalStorageInfo(ctx, metrics))

	storageInfo.Backend = objLayer.BackendInfo()
	for _, sinfo := range replies {
		storageInfo.Disks = append(storageInfo.Disks, sinfo.Disks...)

var ntpServer = env.Get(ntpServerEnv, "")

// UTCNowNTP - is similar in functionality to UTCNow()
// but only used when we do not wish to rely on system
// time.
func UTCNowNTP() (time.Time, error) {
	// ntp server is disabled
	if ntpServer == "" {
		return time.Now().UTC(), nil
	}
	return ntp.Time(ntpServer)
}

// Retention - bucket level retention configuration.
type Retention struct {
	Mode        RetMode

* **預設**情況下，這表示你每個 IP 位址**只能**使用**一張 HTTPS 憑證**。
    * 不論你的伺服器多強或你在上面跑的應用多小。
    * 不過，這是有**解法**的。
* 在 **TLS** 協定（在 HTTP 之前於 TCP 層處理加密的協定）上有個**擴充**稱為 **[<abbr title="Server Name Indication - 伺服器名稱指示">SNI</abbr>](https://en.wikipedia.org/wiki/Server_Name_Indication)**。
    * 這個 SNI 擴充讓單一伺服器（單一 IP 位址）可以擁有**多張 HTTPS 憑證**，並服務**多個 HTTPS 網域／應用**。

                        // if we catch a ChecksumFailedException, it means the transfer/read succeeded, but the
                        // checksum doesn't match. This could be a problem with the server (ibiblio HTTP-200 error
                        // page), so we'll try this up to two times. On the second try, we'll handle it as a bona-fide
                        // error, based on the repository's checksum checking policy.

		// performed at '/' resource should be routed by the muxer,
		// the assumption is simply such that requests without a bucket
		// in a federated setup cannot be proxied, so serve them at
		// current server.
		if bucket == "" {
			h.ServeHTTP(w, r)
			return
		}

		// MakeBucket requests should be handled at current endpoint
		if r.Method == http.MethodPut && bucket != "" && object == "" && r.URL.RawQuery == "" {

        final SystemHelper systemHelper = ComponentUtil.getSystemHelper();
        final long execTime = systemHelper.getCurrentTimeAsLong();
        if (logger.isDebugEnabled()) {
            logger.debug("Sending {} documents to a server.", docList.size());
        }
        try {
            if (fessConfig.isThumbnailCrawlerEnabled()) {
                final ThumbnailManager thumbnailManager = ComponentUtil.getThumbnailManager();

       * fastest (more than twice as fast as the Java implementation, vs ~1.5x with non-final static
       * fields, on x86_32) under the Hotspot server compiler. The reason is obviously that the
       * non-final fields need to be reloaded inside the loop.
       *
       * And, no, defining (final or not) local variables out of the loop still isn't as good
