## 多文件上传

FastAPI 支持同时上传多个文件。

可用同一个「表单字段」发送含多个文件的「表单数据」。

上传多个文件时，要声明含 `bytes` 或 `UploadFile` 的列表（`List`）：

{* ../../docs_src/request_files/tutorial002_py39.py hl[8,13] *}

接收的也是含 `bytes` 或 `UploadFile` 的列表（`list`）。


/// note | 技术细节

也可以使用 `from starlette.responses import HTMLResponse`。

  override fun matchesSocket(sslSocket: SSLSocket): Boolean = socketAdapterFactory.matchesSocket(sslSocket)

  override fun configureTlsExtensions(
    sslSocket: SSLSocket,
    hostname: String?,
    protocols: List<Protocol>,
  ) {
    getDelegate(sslSocket)?.configureTlsExtensions(sslSocket, hostname, protocols)
  }

You can optionally deploy your FastAPI app to <a href="https://fastapicloud.com" class="external-link" target="_blank">FastAPI Cloud</a>, go and join the waiting list if you haven't. 🚀

If you already have a **FastAPI Cloud** account (we invited you from the waiting list 😉), you can deploy your application with one command.

Before deploying, make sure you are logged in:

...the prefix must not include a final `/`.

So, the prefix in this case is `/items`.

We can also add a list of `tags` and extra `responses` that will be applied to all the *path operations* included in this router.

And we can add a list of `dependencies` that will be added to all the *path operations* in the router and will be executed/solved for each request made to them.
