利用Python编写一个简单的浏览器检查工具

　　网站：https://www.whatismybrowser.com/detect/what-is-my-user-agent/， 可以检测浏览器的版本，本代码利用requests模块，发起请求到该网站检查浏览器的信息

 1 import requests
 2 from lxml import etree
 3 import termcolor
 4 
 5 class UserAgentTest:
 6     def __init__(self, user_agent) -> None:
 7         self.url = 'https://www.whatismybrowser.com/detect/what-is-my-user-agent/'
 8         self.user_agent = user_agent
 9     
10     def run(self):
11         headers = {
12             'User-Agent': self.user_agent
13         }
14         try:
15             response = requests.get(url=self.url, headers=headers).text
16             # print(response)
17             html = etree.HTML(response)
18             result = html.xpath('//div[@class="detected_result"]//text()')[1]
19           
20             print("Your Browser is: \n", termcolor.colored(result, 'blue'))
21         except Exception as e:
22             print(e)
23 
24 
25 if __name__ == "__main__":
26     user_agent = input("Enter user agent: ")
27     useragenttest = UserAgentTest(user_agent=user_agent)
28     useragenttest.run()
