Python爬虫教程-10-UserAgent和常见浏览器UA值
有时候使用爬虫会被网站封了IP，所以需要去模拟浏览器，隐藏用户身份，
UserAgent
- 包含浏览器信息，用户身份，设备系统信息
- UserAgent：用户代理，简称UA，属于headers的一部分，服务器通过UA来判断访问者身份
- 使用方法：复制粘贴即可
- 案例v10UA文件：https://xpwi.github.io/py/py爬虫/py10UA.py
# 更改UserAgent，进行伪装
from urllib import request,error
if __name__ == '__main__':
url = "http://www.baidu.com/"
try:
# 1.使用head方法伪装UA
# headers = {}
# headers['User-Agent'] = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.835.163'
# req = request.Request(url, headers=headers)
# 2.使用add_header方法
req = request.Request(url)
req.add_header("User-Agent","Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.835.163")
rsp = request.urlopen(req)
html = rsp.read().decode()
print(html)
except error.HTTPError as e:
print(e)
except error.URLError as e:
print(e)
except Exception as e:
print(e)
print("访问完成！")
