使用面向对象的方式设计一段python多线程爬虫代码

可以这样：

import threading
import requests

def spider(url):
response = requests.get(url)
print(response.text)

if __name__ == '__main__':
url_list = ['http://www.example.com/1.html', 'http://www.example.com/2.html', 'http://www.example.com/3.html']
threads = []
for url in url_list:
t = threading.Thread(target=spider, args=(url,))
threads.append(t)
t.start()
for t in threads:
t.join()
