Question

爬虫代码

import requests
url = 'http://filehelper.weixin.qq.com'
headers={
        'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.61 Safari/537.36'
    }
response = requests.get(url=url, headers=headers)
page_text=response.text
with open("url.html",'w',encoding='utf-8') as fp:
    fp.write(page_text)
print("保存成功！")

错误：

requests.exceptions.SSLError: HTTPSConnectionPool(host='filehelper.weixin.qq.com', port=443): Max retries exceeded with url: / (Caused by SSLError(SSLError(1, '[SSL: NO_CIPHERS_AVAILABLE] no ciphers available (_ssl.c:841)'),))
