python3.5里面 urlopen 代理不能识别proxies关键字的问题

urllib.request 里面 的 urlopen  proxies={‘http’:proxies} 无法识别出现 下列错误如何解决

got an unexpected keyword argument 'proxies'

首先通过 cmd，用命令 python -v

找到   C:\Users\computorname\AppData\Local\Programs\Python\Python35\lib

这个位置就是 python的 源码函数类库的存储位置

用sublime或其他编辑器 查找上面的文件夹， 查找内容为 def urlopen

发现上面 test/testurllib.py里面有 proxies关键字

就导入这个类库即可 from test.test_urllib import urlopen

from contextlib import closing

# from urllib.request import urlopen

from test.test_urllib import urlopen

# import urllib

# import requests

proxyConfig="http://%s:%s@%s"%("username","password","10.110.4.235:8080")

print(proxyConfig)

with closing(urlopen("https://www.python.org",proxies={'http':proxyconfig})) as page:

    for line in page:

        print(line)
