Python使用Requests下载时获取实时下载进程

request_url = 'https://download.jetbrains.com/idea/ideaIU-2018.2.1.exe'
res = requests.get(request_url , stream=True)

content_length = res.headers['content-length']

import requests
from contextlib import closing
 
if __name__ == '__main__':
    url = 'https://download.jetbrains.com/idea/ideaIU-2018.2.1.exe'
    with closing(requests.get(url, stream=True)) as response:
        chunk_size = 1024  # 单次请求最大值
        content_size = int(response.headers['content-length'])  # 内容体总大小
        data_count = 0
        with open('idea.exe', "wb") as file:
            for data in response.iter_content(chunk_size=chunk_size):
                file.write(data)
                data_count = data_count + len(data)
                now_jd = (data_count / content_size) * 100
                print("\r 文件下载进度：%d%%(%d/%d) - %s" % (now_jd, data_count, content_size, url), end=" ")
