AttributeError: 'module' 对象没有属性 'urlretrieve' [英] AttributeError: 'module' object has no attribute 'urlretrieve'

问题描述

我正在尝试编写一个程序，该程序将从网站下载 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:

I am trying to write a program that will download mp3's off of a website then join them together but whenever I try to download the files I get this error:

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'

导致此问题的线路是

raw_mp3.add = urllib.urlretrieve("http://www-scf.usc.edu/~chiso/oldspice/m-b1-hello.mp3")

推荐答案

当您使用 Python 3 时，不再有 urllib 模块.它已被拆分为多个模块.

As you're using Python 3, there is no urllib module anymore. It has been split into several modules.

这相当于urlretrieve:

import urllib.request
data = urllib.request.urlretrieve("http://...")

urlretrieve 的行为方式与它在 Python 2.x 中的行为完全相同，因此它可以正常工作.

urlretrieve behaves exactly the same way as it did in Python 2.x, so it'll work just fine.

基本上:

• urlretrieve 将文件保存到一个临时文件并返回一个元组 (filename, headers)
• urlopen 返回一个 Request 对象，其 read 方法返回一个包含文件内容的字节串

• urlretrieve saves the file to a temporary file and returns a tuple (filename, headers)
• urlopen returns a Request object whose read method returns a bytestring containing the file contents
