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)
