### Déployer votre application (optionnel) { #deploy-your-app-optional }

Vous pouvez, si vous le souhaitez, déployer votre application FastAPI sur [FastAPI Cloud](https://fastapicloud.com), allez vous inscrire sur la liste d'attente si ce n'est pas déjà fait. 🚀

 * Updating the table can change the contents of those collections, and updating the collections
 * will change the table.
 *
 * <p>All methods that modify the table are optional, and the views returned by the table may or may
 * not be modifiable. When modification isn't supported, those methods will throw an {@link
 * UnsupportedOperationException}.
 *
 * <h3>Implementations</h3>
 *
 * <ul>

        return parser.getAttributeValue(null, "implementation");
    }

    /**
     * Attempts to load the named implementation, uses default implementation if no name is given.
     *
     * @param name The optional implementation name
     * @param defaultClazz The default implementation type
     * @return Custom implementation type if one was given; otherwise default implementation type
     */

 * For production or when the IdP is configured with a different URL, you should
 * set one of the following:</p>
 *
 * <h3>Option 1: Set base URL (recommended for simplicity)</h3>
 * <pre>
 * # All SP URLs will be derived from this base URL
 * saml.sp.base.url=https://your-fess-server.example.com
 * </pre>
 *
 * <h3>Option 2: Set individual SP URLs</h3>
 * <pre>
 * # SP Entity ID (Audience URI in IdP)

* 许多额外特性（归功于 Starlette），例如：
    * **WebSockets**
    * 基于 HTTPX 和 `pytest` 的极其简单的测试
    * **CORS**
    * **Cookie Sessions**
    * ……以及更多。

### 部署你的应用（可选） { #deploy-your-app-optional }

你可以选择把 FastAPI 应用部署到 [FastAPI Cloud](https://fastapicloud.com)，如果还没有的话去加入候补名单吧。🚀

如果你已经有 **FastAPI Cloud** 账号（我们从候补名单邀请了你 😉），你可以用一个命令部署你的应用。

<div class="termy">

```console
$ fastapi deploy

    }

    /**
     * Executes the upgrade goal.
     * Template method that calls doUpgrade and optionally saves modifications.
     */
    @Override
    public int execute(UpgradeContext context) throws Exception {
        UpgradeOptions options = context.options();

        // Determine target model version
        // Default to 4.0.0 unless --all is specified or explicit --model-version is provided

No more typing the wrong key names, coming back and forth between docs, or scrolling up and down to find if you finally used `username` or `user_name`.

### Short { #short }

It has sensible **defaults** for everything, with optional configurations everywhere. All the parameters can be fine-tuned to do what you need and to define the API you need.

But by default, it all **"just works"**.

### Validation { #validation }

 *
 * ### Query
 *
 * The query is optional: it can be null, empty, or non-empty. For many HTTP URLs the query string
 * is subdivided into a collection of name-value parameters. This class offers methods to set the
 * query as the single string, or as individual name-value parameters. With name-value parameters
 * the values are optional and names may be repeated.

 * Table} interface.
 *
 * <p>The views returned by {@link #column}, {@link #columnKeySet()}, and {@link #columnMap()} have
 * iterators that don't support {@code remove()}. Otherwise, all optional operations are supported.
 * Null row keys, columns keys, and values are not supported.
 *
 * <p>Lookups by row key are often faster than lookups by column key, because the data is stored in
