如何利用Python對接又拍雲接口，實現影片上傳進度顯示

pip install requests tqdm

import requests
import tqdm

def upload_video(file_path, bucket_name, api_key, api_secret):
    # 构造上传文件的URL
    url = f'https://v0.api.upyun.com/{bucket_name}/'
    # 读取视频文件
    video_file = open(file_path, 'rb')
    # 计算视频文件总大小
    total_size = len(video_file.read())
    video_file.seek(0) # 将文件指针返回到文件开头
    # 构造请求头
    headers = {
        'Content-Length': str(total_size),
        'Content-Type': 'video/mp4',
        'Authorization': f'UPYUN {api_key}:{api_secret}'
    }
    # 构造进度条
    progress_bar = tqdm.tqdm(total=total_size, unit='B', unit_scale=True)
    # 发送文件分块进行上传
    for chunk in video_file:
        # 利用requests发送请求，进行文件分块上传
        response = requests.post(url, data=chunk, headers=headers)
        # 更新进度条
        progress_bar.update(len(chunk))
    # 关闭进度条
    progress_bar.close()
    # 关闭文件
    video_file.close()

# 示例用法
if __name__ == '__main__':
    file_path = 'test.mp4'
    bucket_name = 'your_bucket_name'
    api_key = 'your_api_key'
    api_secret = 'your_api_secret'
    upload_video(file_path, bucket_name, api_key, api_secret)
