Django ImportError無法導入名稱請求

我正在使用Antonio Mele的Django-By-Example書籍學習Django。現在我到了第5章，現在我正在嘗試創建圖像共享應用程序。但是，儘管按照該章中的所有說明，當我嘗試在django開發服務器中添加來自外部URL的圖像時，我得到了ImportError。Django ImportError無法導入名稱請求

ImportError at /images/create/ 

cannot import name request 

Request URL: http://127.0.0.1:8000/images/create/?title=%20Django%20and%20Duke&url=http://upload.wikimedia.org/wikipedia/commons/8/85/Django_Reinhardt_and_Duke_Ellington_(Gottlieb).jpg. 
Django Version:  1.8.6 
Exception Location:  /home/ciotar/projects/VirtualEnvs/env/bookmarks/bookmarks/images/forms.py in <module>, line 1 
Python Version:  2.7.11

我使用Pycharm，並建立從活動的virtualenv例如蟒蛇3.5翻譯。不知道爲什麼Django運行Python 2.7。我不知道這個問題是否會出現，因爲forms.py和views.py模塊之間的'請求'名稱衝突？

這是由於在Python差異版。

在Python 2.7，你可能需要更換：

from urllib import request

在forms.py與

import urllib2

再次urllib2 > Request模塊不具有urlopen方法。所以，你將不得不更換線路

response = request.urlopen(image_url)

有：

response = urllib2.urlopen(image_url)

在forms.py

有許多關於這個SO post

的urllib和urllib2的位置之間的差異一個很好的討論謝謝，切換到urllib2修復了錯誤 – WaR1o
