环境：python3.X

代码：

 # coding:utf8

import urllib

from bs4 import BeautifulSoup

url = "http://www.baidu.com"

print("第一种方法：")

response1 = urllib.request.urlopen(url)

print(response1.getcode())

bs = BeautifulSoup(response1.read(), 'html.parser', from_encoding='utf8')

print(bs.find_all('a'))

eclipse 提示错误 AttributeError: module 'urllib' has no attribute 'request'

但是如果引入import http.cookiejar结果就正常。。。什么原因呢
