python 使用代理

import urllib.request
url='http://whatismyip.com.tw'
p=urllib.request.ProxyHandler({'http':'119.6.144.73:81'})
o=urllib.request.build_opener(p)
o.addheaders=[('User-Agent','Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:73.0) Gecko/20100101 Firefox/73.0')]
urllib.request.install_opener(o)
r=urllib.request.urlopen(url)
h=r.read().decode('utf-8')
print(h)
