Streamlit上传并解压RAR文件

测试程序如下：

import streamlit as st
import os
import rarfile

def unrar_file(rar_file, output_dir):
    with rarfile.RarFile(rar_file, 'r') as rar_ref:
        rar_ref.extractall(output_dir)
uploaded_files = st.file_uploader(":rainbow[**请上传文件压缩包**]", type=['zip','rar'], accept_multiple_files=True)
for uploaded_file in uploaded_files:
    archive_file = os.path.join('./', uploaded_file.name)
    with open(archive_file, 'wb') as f:
        f.write(uploaded_file.getvalue())

    unrar_file('./'+uploaded_file.name, './unrar_output')

报错：rarfile.BadRarFile: Failed the read enough data: req=1048576 got=5
