我正在尝试编写一个程序,将从网站下载mp3然后将它们连接在一起但是每当我尝试下载文件时,我都会收到此错误:
Traceback (most recent call last):
File "/home/tesla/PycharmProjects/OldSpice/Voicemail.py", line 214, in <module> main()
File "/home/tesla/PycharmProjects/OldSpice/Voicemail.py", line 209, in main getMp3s()
File "/home/tesla/PycharmProjects/OldSpice/Voicemail.py", line 134, in getMp3s
raw_mp3.add = urllib.urlretrieve("http://www-scf.usc.edu/~chiso/oldspice/m-b1-hello.mp3")
AttributeError: 'module' object has no attribute 'urlretrieve'
导致此问题的行是
raw_mp3.add = urllib.urlretrieve("http://www-scf.usc.edu/~chiso/oldspice/m-b1-hello.mp3")

当您使用Python 3时,不再有urllib模块了。它已被分成几个模块。
这相当于urlretrieve:
import urllib.request
data = urllib.request.urlretrieve("http://...")
urlretrieve的行为方式与Python 2.x中的行为完全相同,因此它可以正常工作。
基本上:
urlretrieve
将文件保存到临时文件并返回元组(filename, headers)
urlopen
返回Request
对象,其read
方法返回包含文件内容的字节字符串答案 1 :(得分:6)
Python 2 + 3兼容解决方案是:
import sys
if sys.version_info[0] >= 3:
from urllib.request import urlretrieve
else:
# Not Python 3 - today, it is most likely to be Python 2
# But note that this might need an update when Python 4
# might be around one day
from urllib import urlretrieve
# Get file from URL like this:
urlretrieve("http://www-scf.usc.edu/~chiso/oldspice/m-b1-hello.mp3")

假设您有以下代码行
MyUrl = "www.google.com" #Your url goes here
urllib.urlretrieve(MyUrl)
如果您收到以下错误消息
AttributeError: module 'urllib' has no attribute 'urlretrieve'
然后您应该尝试使用以下代码来解决问题:
import urllib.request
MyUrl = "www.google.com" #Your url goes here
urllib.request.urlretrieve(MyUrl)
