大佬们这个爬虫的opener怎么报错了
import urllib.requesturl = '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

import urllib.request
# 方法1： 直接用创建的opener打开。
url = "https://www.whatismyip.com"
proxy_support = urllib.request.ProxyHandler({'http': '125.108.106.64:9000'})
opener = urllib.request.build_opener(proxy_support)
opener.addheaders = [('User-agent', 'Firefox')]
response = opener.open(url)
html = response.read().decode('utf-8')
print(html)
# 方法2：让创建的opener变成默认opener，然后用默认的urlopen方法打开。
url = "https://www.whatismyip.com"
proxy_support = urllib.request.ProxyHandler({'http': '125.108.106.64:9000'})
opener = urllib.request.build_opener(proxy_support)
opener.addheaders = [('User-agent', 'Firefox')]
urllib.request.install_opener(opener)
response = urllib.request.urlopen(url)
html = response.read().decode('utf-8')
print(html)
