import urllib.request

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

proxy_support = urllib.request.ProxyHandler({'http':'163.125.64.131:9999'})

opener = urllib.request.build_opener(proxy_support)

urllib.request.install_opener(opener)

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

print(html)


提示错误：

先直接request下，看看，或许是代理出了问题？

谦虚求学

IP 地址正确吗  你的header 会修改吗  你好好看第55讲了吗

404NOT

一样的问题，我在代码里把User-Agent设置了一下就好了，好像是反爬虫的墙，然后这样做我的IP却没有修改成功

新手诚恳学习

这样可以直接用可疑的地址

加上这句:

1. opener.addheaders = [('User-Agent','Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36')]
   

复制代码

然后代理多试几个,免费的有时候不能用
