关于python使用代理ip的问题

[Hello world753]

import urllib.request
#import random

url = 'http://www.whatismyip.com.tw'
#iplist=['121.31.192.117:8123','27.9.157.5:8090','123.57.206.140:8090','116.31.127.1:80']
proxy_support = urllib.request.ProxyHandler({'http':'116.31.127.1:80'})    ##############################

opener = urllib.request.build_opener(proxy_support)
opener.addheaders = [('User-Agent','Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36')]

urllib.request.install_opener(opener)

response = urllib.request.urlopen(url)
html = response.read().decode('utf-8')

print(html)

这段代码为什么运行不了？
但是将上面########处http改为https就可以显示ip 但显示的是本机ip，而不是代理ip？为什么？

改成{'http':'http://116.31.127.1:80'}?
