使用requests获取网页源码的时候报错:failed to decode gzip

import requests
if __name__ == "__main__":
    url = "http://www.wnlwedu.com/"
    r = requests.get(url=url)
    print r.text
报错信息：
  
requests.exceptions.ContentDecodingError: ('Received response with content-encoding: gzip, but failed to decode it.', error('Error -3 while decompressing: incorrect data check',))
requests不是会自动解压gzip吗？
