文件大小5622620小于此API允许的最小值:“20000000”,Python Box SDK

将文件上传到box时,会出现一个错误,显示文件大小小于要求。这是我的代码:

import os
from boxsdk import JWTAuth, Client
import schedule
import time

directory = '/videos'


def save_video():
    retval = os.getcwd()
    help = (retval)
    os.chdir(help + directory)
    retval = os.getcwd()

    config = JWTAuth.from_settings_file('box_config.json')
    client = Client(config)

    for file_name in os.listdir(retval):
        print(file_name)
        if file_name == 'box_config.json':
            continue
        file_size = os.path.getsize(file_name)
        print(file_name)
        folder_id = '144613233618'

        upload_session = client.folder(folder_id=folder_id).create_upload_session(file_size, file_name)
        print('Created upload session {0} with chunk size of {1} bytes'.format(upload_session.id, upload_session.part_size))

        chunked_upload = upload_session.get_chunked_uploader(file_name)
        uploaded_file = chunked_upload.start()
        print('File "{0}" uploaded to Box with file ID {1}'.format(uploaded_file.name, uploaded_file.id))

        os.remove(file_name)



schedule.every().day.at("11:34").do(save_video)

while True:
    schedule.run_pending()
    time.sleep(1)

我将上传多个文件作为序列,一些文件的大小可能小于2000万。
