使用Python将zip文件拆分成块

import os
import zipfile

def split_zip_file(file_path, chunk_size):
    # 创建一个目录来存储拆分后的文件块
    output_dir = os.path.dirname(file_path)
    output_dir = os.path.join(output_dir, 'split_files')
    os.makedirs(output_dir, exist_ok=True)

    # 打开zip文件
    with zipfile.ZipFile(file_path, 'r') as zip_ref:
        # 获取zip文件中的所有文件列表
        file_list = zip_ref.namelist()

        # 拆分zip文件
        for file_name in file_list:
            # 读取文件内容
            with zip_ref.open(file_name) as file:
                # 按照指定的块大小拆分文件
                chunk_num = 0
                while True:
                    chunk = file.read(chunk_size)
                    if not chunk:
                        break

                    # 生成拆分后的文件名
                    output_file_name = f'{file_name}.part{chunk_num}'

                    # 写入拆分后的文件块
                    with open(os.path.join(output_dir, output_file_name), 'wb') as output_file:
                        output_file.write(chunk)

                    chunk_num += 1

file_path = 'path/to/your/zip/file.zip'
chunk_size = 1024 * 1024  # 指定块大小为1MB

split_zip_file(file_path, chunk_size)
