## 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`）。

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

            task.include("package-list", "element-list");
            task.into(layout.getBuildDirectory().dir("groovyPackageList"));
        });

* The Kubernetes API server now supports the ability to break large LIST calls into multiple smaller chunks.  A client can specify a limit to the number of results to return, and if more results exist a token will be returned that allows the client to continue the previous list call repeatedly until all results are retrieved.  The resulting list is identical to a list call that does not perform chunking thanks to capabilities provided by etcd3.  This allows the server...

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:

<div class="termy">

```console
$ fastapi login

        // Value taken from p2
        // ----------------------------------------------------------------------

        assertEquals("mailing-list", p4.getMailingLists().get(0).getName());

        // ----------------------------------------------------------------------
        // Value taken from p1
