O marcador `@pytest.mark.anyio` informa ao pytest que esta função de teste deve ser invocada de maneira assíncrona:

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[7] *}

/// tip | Dica

Note que a função de teste é `async def` agora, no lugar de apenas `def` como quando estávamos utilizando o `TestClient` anteriormente.

    Note over Proxy: Proxy adds forwarded headers

    Note over Server: Server interprets headers<br/>(if --forwarded-allow-ips is set)

* 它接收你的应用的每一个**请求**。
* 然后它可以对这个**请求**做一些事情或者执行任何需要的代码。
* 然后它将这个**请求**传递给应用程序的其他部分（某个*路径操作*）处理。
* 之后它获取应用程序生成的**响应**（由某个*路径操作*产生）。
* 它可以对该**响应**做一些事情或者执行任何需要的代码。
* 然后它返回这个**响应**。

/// note | 技术细节

如果你有使用 `yield` 的依赖，依赖中的退出代码会在中间件之后运行。

如果有任何后台任务（会在[后台任务](background-tasks.md)一节中介绍，你稍后会看到），它们会在所有中间件之后运行。

///

## 创建中间件 { #create-a-middleware }

要创建中间件，你可以在函数的顶部使用装饰器 `@app.middleware("http")`。

/// info | 說明

要使用表單，首先安裝 [`python-multipart`](https://github.com/Kludex/python-multipart)。

請先建立[虛擬環境](../virtual-environments.md)、啟用後再安裝，例如：

```console
$ pip install python-multipart
```

///

/// note | 注意

此功能自 FastAPI 版本 `0.113.0` 起支援。🤓

## 針對表單的 Pydantic 模型 { #pydantic-models-for-forms }

你只需要宣告一個 **Pydantic 模型**，包含你要接收為 **表單欄位** 的欄位，然後將參數宣告為 `Form`：

## 1. Prerequisites

- Familiarity with [chroot](http://man7.org/linux/man-pages/man2/chroot.2.html)
- Chroot installed on your machine.

## 2. Install MinIO in Chroot

> **Note:** MinIO community edition is now distributed as source code only. Pre-compiled binaries are no longer provided for new releases.

Build MinIO from source and install it in the chroot directory:

```sh

   *
   * <p>This implementation synchronously delegates to {@link #load}. It is recommended that it be
   * overridden with an asynchronous implementation when using {@link
   * CacheBuilder#refreshAfterWrite}.
   *
   * <p><b>Note:</b> <i>all exceptions thrown by this method will be logged and then swallowed</i>.
   *
   * @param key the non-null key whose value should be loaded
   * @param oldValue the non-null old value corresponding to {@code key}
