如何在Python中使用代理IP进行文件下载

import requests

# 代理IP
proxies = {
  'http': 'http://IPAddress:port',
  'https': 'http://IPAddress:port',
}

# 文件下载链接
url = 'http://pidancode.com/logo.png'

# 发送请求，并保存文件
r = requests.get(url, stream=True, proxies=proxies)
with open('pidancode_logo.png', 'wb') as f:
    for chunk in r.iter_content(chunk_size=1024):
        if chunk:
            f.write(chunk)
