反爬中设置随机代理

反爬中有一个使用随机代理的

 

 

#　导入随机函数模块
import random

# 构建 user_agent 集合代理
user_agent = [
    'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; Trident/4.0)',
    'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:34.0) Gecko/20100101 Firefox/34.0',
    'Mozilla/5.0 (Windows; U; Windows NT 5.2) AppleWebKit/525.13 (KHTML, like Gecko) Version/3.1 Safari/525.13',
    'Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0)',
    'Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Win64; x64; Trident/4.0)'
]

# 在headers 里生成随机代理
headers = {
    'user-Agent' : random.choice(user_agent)
}

print(headers)
