如何从BytesIO - Flask的数组创建zipFile

from io import BytesIO
from zipfile import ZipFile
from flask import Flask, send_file

app = Flask(__name__)

@app.route('/create_zip')
def create_zip():
    # 创建一个BytesIO对象，用于在内存中存储zip文件
    zip_data = BytesIO()

    # 创建一个ZipFile对象，将文件写入BytesIO对象中
    with ZipFile(zip_data, 'w') as zip_file:
        # 将文件或数据添加到zip文件中
        zip_file.writestr('file1.txt', 'This is file 1')
        zip_file.writestr('file2.txt', 'This is file 2')

    # 将BytesIO对象指针指向开头
    zip_data.seek(0)

    # 返回zip文件给客户端
    return send_file(zip_data, attachment_filename='example.zip', as_attachment=True)

if __name__ == '__main__':
    app.run()
