因?yàn)槲业膒ython版本是3.6的，所以引入的是 import urllib.request

然后使用 response = urllib.request.urllopen(url)一直出問(wèn)題，這是怎么回事呢。

import?urllib.request
import?http.cookiejar
url?=?"www.baidu.com"
#--------------方法一--------------
#獲取地址內(nèi)容
response3?=?urllib.request.urlopen(url)
#判斷狀態(tài)碼等于200成功
print?(response3.getcode())
#讀取獲取的內(nèi)容
cont?=?response3.read()
print?(cont)

問(wèn)題提示：
