你可以使用python请求

import os
import requests


outfile = os.path.join(SAVE_DIR, file_name)
response = requests.get(URL, stream=True)
with open(outfile,'wb') as output:
  output.write(response.content)

你可以使用shutil

import os
import requests
import shutil
 
outfile = os.path.join(SAVE_DIR, file_name)
response = requests.get(url, stream = True)
with open(outfile, 'wb') as f:
  shutil.copyfileobj(response.content, f)

如果你从受限的url下载，不要忘记在标题中包含访问令牌

你可以在Python 2和3上使用PycURL。

import pycurl

FILE_DEST = 'pycurl.html'
FILE_SRC = 'http://pycurl.io/'

with open(FILE_DEST, 'wb') as f:
    c = pycurl.Curl()
    c.setopt(c.URL, FILE_SRC)
    c.setopt(c.WRITEDATA, f)
    c.perform()
    c.close()

Python 3

urllib.request.urlopen 进口urllib.request Response = urllib.request.urlopen('http://www.example.com/') HTML = response.read() urllib.request.urlretrieve 进口urllib.request urllib.request.urlretrieve (' http://www.example.com/songs/mp3.mp3 ', ' mp3.mp3 ') 注意:根据文档，urllib.request.urlretrieve是一个“遗留接口”，并且“在未来可能会被弃用”(感谢gerrit)

Python 2

urllib2。urlopen(谢谢科里) 进口urllib2 Response = urllib2.urlopen('http://www.example.com/') HTML = response.read() urllib。urlretrieve(感谢PabloG) 进口urllib urllib.urlretrieve (' http://www.example.com/songs/mp3.mp3 ', ' mp3.mp3 ')

为了这个目的，用纯Python编写了wget库。从2.0版开始，它就为urlretrieve注入了这些特性。

import urllib2
mp3file = urllib2.urlopen("http://www.example.com/songs/mp3.mp3")
with open('test.mp3','wb') as output:
  output.write(mp3file.read())

open('test.mp3'，'wb')中的wb以二进制模式打开文件(并擦除任何现有文件)，以便您可以使用它保存数据而不仅仅是文本。

使用wget模块:

import wget
wget.download('url')
