[已解决]大佬们这个爬虫的opener怎么报错了

C语言真好

import urllib.request
url = 'http://www.whatismyip.com.tw'
proxy_support = urllib.request.ProxyHandler({'http': '113.123.0.100:3256'})  # 创建一个代理ip
opener = urllib.request.build_opener(proxy_support)  # 创建一个opener
urllib.request.build_opener(opener)  # 将创建好的apener安装上
response = urllib.request.urlopen(url)
html = response.read().decode('utf-8')
print(html)



这是报错
Traceback (most recent call last):
  File "E:/Users/ASUS/Desktop/python/pachong.py", line 5, in <module>
    urllib.request.build_opener(opener)  # 将创建好的apener安装上
  File "F:\python1\lib\urllib\request.py", line 600, in build_opener
    opener.add_handler(h)
  File "F:\python1\lib\urllib\request.py", line 438, in add_handler
    raise TypeError("expected BaseHandler instance, got %r" %
TypeError: expected BaseHandler instance, got <class 'urllib.request.OpenerDirector'>
