如何使用Python下载文件 [英] How to download a file using Python

问题描述

我尝试使用Python从互联网上下载某些东西，我使用urllib模块中的 urllib.retriever ，但是我无法使其工作。我想要将下载的文件保存到我选择的位置。
如果有人可以向我解释如何使用明确的例子，那将是非常感谢。

I tried to download something from the Internet using Python, I am using urllib.retriever from the urllib module but I just can't get it work. I would like to be able to save the downloaded file to a location of my choice. If someone could explain to me how to do it with clear examples, that would be VERY appreciated.

推荐答案

我建议使用 urllib2 ，如下所示：

I suggest using urllib2 like so:

source = urllib2.urlopen("http://someUrl.com/somePage.html").read()
open("/path/to/someFile", "wb").write(source)

你甚至可以缩短它（尽管你不想要如果您打算将每个个人电话包含在中尝试 - ，除外）缩短：

You could even shorten it to (although, you wouldnt want to shorten it if you plan to enclose each individual call in a try - except):

open("/path/to/someFile", "wb").write(urllib2.urlopen("http://someUrl.com/somePage.html").read())
