[已解决]自己写55课的opener遇到问题

chenyixin1992

在55课中，小甲鱼老师讲到了自己定制opener，视频中他用的是安装opener以覆盖默认opener的方法。现在我自己尝试了用opener.open(url)的方法方法访问whatismyip.com，但总是报错，看提示好像是说超时了。请问是为什么？我自己尝试了用普通的urllib.request.urlopen(url)就没有问题



——————————————————以下是代码————————————————————
import urllib.request

url='http://www.whatismyip.com.tw'

proxy_support=urllib.request.ProxyHandler({'http':'222.162.36.226'})

opener=urllib.request.build_opener(proxy_support)

opener.addheaders=[('User-Agent','Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36')]

response=opener.open(url)

html=response.read().decode('utf-8')

print(html)

问题并不在于自定义的 opener, 而是你使用的代理失效了, 去掉代理就正常了
