Python怎么下载URL指向的文件？

Question

请问大家Python怎样下载一个url请求的文件，可能我描述的不是很清楚，直接贴代码。

比如是这样的url：http://www.aaa.com/download.php?aid=123

在浏览器中打开这个url，就会直接下载一个文档，请问如何用Python下载这个url指向的文档？

Answer 1

Just write to the file
f=urllib2.urlopen(url)
data=f.read()
f=open(path,'wb')
f.write(data)
f.close()

Answer 2

urllib2.urlretrieve(url, filename)

So lazy, just google it →_→

Answer 3

There is a problem with the above answer. There is no urlretrieve function in urllib2. This function is in urllib.

Answer 4

The simplest implementation is to use wget

1. Installation

Directly use the requests library to download. There are many examples on the Internet. There are also corresponding download methods for large files.
