- To be able to reliably use S3 multipart APIs feature of the SDKs without re-inventing the wheel of pre-signing the each URL in multipart API. This is very tedious to implement with all the scenarios of fault tolerance that's already implemented by the client SDK. The general client SDKs don't support multipart with presigned URLs.

	checksumCombined = append(checksumCombined, part3Checksum.Raw...)

	// Create the final checksum (checksum of the combined checksums)
	// Add BOTH the multipart flag AND the includes-multipart flag
	finalChecksumType := checksumType | ChecksumMultipart | ChecksumIncludesMultipart
	finalChecksum := NewChecksumFromData(finalChecksumType, checksumCombined)

	// Set WantParts to indicate 3 parts

The [`python-multipart`](https://github.com/Kludex/python-multipart) package is automatically installed with **FastAPI** when you run the `pip install "fastapi[standard]"` command.

However, if you use the `pip install fastapi` command, the `python-multipart` package is not included by default.

當你使用 `pip install "fastapi[standard]"` 指令安裝時，[`python-multipart`](https://github.com/Kludex/python-multipart) 套件會隨 FastAPI 自動安裝。

不過若只執行 `pip install fastapi`，預設不會包含 `python-multipart`。

若要手動安裝，請先建立並啟用一個[虛擬環境](../../virtual-environments.md)，接著執行：

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

因為 OAuth2 會以「form data」傳送 `username` 與 `password`。

当你使用命令 `pip install "fastapi[standard]"` 安装 **FastAPI** 时，[`python-multipart`](https://github.com/Kludex/python-multipart) 包会自动安装。

但是，如果你使用 `pip install fastapi`，默认不会包含 `python-multipart` 包。

如需手动安装，请先创建并激活[虚拟环境](../../virtual-environments.md)，然后执行：

```console
