Python通过requests从一个链接下载存放在临时文件tempfile

import requests
import tempfile


def download(url):
    r = requests.get(url, stream=True)
    file_len = int(r.headers.get('content-length'))
    tf = tempfile.mktemp(suffix='.zip', dir='./')

    f = open(tf, 'wb')

    count = 0
    for ch in r:
        count = count + len(ch)

        f.write(ch)

        progress = ''.format(count / file_len * 100)
        print(f'count/file_len:progress%')
        
    f.close()
