fake_useragent伪装headers

关于反爬的问题，我们要经常伪装不同的浏览器User-Agent来欺骗服务器来完成请求，fake_useragent库则可以模拟指定浏览器的User-Agent或者随机产生一个User-Agent。

• 安装

pip install fake_useragent

• 指定浏览器

from fake_useragent  import UserAgent
ua = UserAgent()

# chrome
print(ua.chrome)
# ie
print(ua.ie)
# firefox
print(ua.firefox)
# opera
print(ua.opera)
# safari
print(ua.safari)

返回虚拟 User-Agent

• 随机浏览器

from fake_useragent  import UserAgent
ua = UserAgent()
print(ua.random)

# 结果

• 案例说明

import requests
from fake_useragent  import UserAgent
ua = UserAgent()
headers = {'User-Agent': ua.random}
url = 'http://www.baidu.com'
req = requests.get(url,headers=headers)
print(req.status_code)

import requests
from fake_useragent import UserAgent

def fakeUserAgent():
    ua = UserAgent()
    headers = {'User-Agent': ua.random}
    return headers

if __name__ == '__main__':
    url = 'http://www.baidu.com'
    req = requests.get(url, headers=fakeUserAgent())
    print(req.status_code)
