创建一个UA池(User-Agent)

import random

def get_ua():
	user_agents = [
		'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36 OPR/26.0.1656.60',

	]
	user_agent = random.choice(user_agents) #random.choice(),从列表中随机抽取一个对象
	return user_agent

将这个函数保存为脚本文件 uagent.py
以下是一个使用实例:

import requests
import uagent

def get_page(url):
	ua = uagent.get_ua()
	headers = {'User-Agent': ua}
	response = requests.get(url = url, headers = headers)
	print(response.text)

if __name__ == '__main__':
	get_page('http://http://httpbin.org/get')
