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`）：

//// tab | Python 3.9+

```Python hl_lines="8  13"
{!> ../../docs_src/request_files/tutorial002_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="10  15"
{!> ../../docs_src/request_files/tutorial002.py!}
```

////

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

```Python hl_lines="10  15"
{!> ../../docs_src/request_files/tutorial002.py!}
```

////

//// tab | 🐍 3️⃣.9️⃣ & 🔛

```Python hl_lines="8  13"
{!> ../../docs_src/request_files/tutorial002_py39.py!}
```

////

👆 🔜 📨, 📣, `list` `bytes` ⚖️ `UploadFile`Ⓜ.

/// note | "📡 ℹ"

👆 💪 ⚙️ `from starlette.responses import HTMLResponse`.

টাইপ হিসেবে, `list` ব্যবহার করুন।

যেহেতু লিস্ট এমন একটি টাইপ যা অভ্যন্তরীণ টাইপগুলি ধারণ করে, আপনি তাদের স্কোয়ার ব্রাকেটের ভিতরে ব্যবহার করুন:

```Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial006_py39.py!}
```

////

//// tab | Python 3.8+

`typing` থেকে `List` (বড় হাতের `L` দিয়ে) ইমপোর্ট করুন:

``` Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial006.py!}
```

For that, use the standard Python `typing.List` (or just `list` in Python 3.9 and above):

//// tab | Python 3.9+

```Python hl_lines="18"
{!> ../../docs_src/extra_models/tutorial004_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="1  20"
{!> ../../docs_src/extra_models/tutorial004.py!}
```

////

## Response with arbitrary `dict`

Als type, vul `list` in.

Doordat de list een type is dat enkele interne types bevat, zet je ze tussen vierkante haakjes:

```Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial006_py39.py!}
```

////

//// tab | Python 3.8+

Van `typing`, importeer `List` (met een hoofdletter `L`):

```Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial006.py!}
```
