最近工作比較忙，也就沒有看python了，今天下午抽空看了下代理ip

proxy = {'http':'120.26.140.95:81'} # 代理IP，我這里只寫一個(gè)作為示范

查看自己的IP可以訪問地址http://www.whatismyip.com.tw/

所以我們只要使用requests請求這個(gè)網(wǎng)站就可以查看我們的ip了，其他也就不多說了，直接上代碼

#!/usr/bin/env python3
# -*- coding:utf-8 -*-

import requests

proxy = {'http':'120.26.140.95:81'}
header = {
        'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 '
                      '(KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36'
    }

url = 'http://www.whatismyip.com.tw/'
response = requests.get(url, proxies=proxy, headers=header)
response.encoding = 'utf-8'
print(response.text)

可以看到下圖中查出來的IP是我使用的代理IP

代理ip可以上西刺代理爬取，那就順便貼下吧
不能太頻繁的訪問，否則。。。我就這樣被封了IP
