使用WWW:机械化将文件下载到磁盘，而无需先将其全部加载到内存中 [英] Using WWW:Mechanize to download a file to disk without loading it all in memory first

问题描述

我正在使用Mechanize来方便某些文件的下载.目前，我的脚本使用以下行来实际下载文件...

I'm using Mechanize to facilitate the downloading of some files. At the moment my script uses the following line to actually download the files...

agent.get('http://example.com/foo').save_as 'a_file_name'

但是，这会将整个文件下载到内存中，然后再将其转储到磁盘中.您如何绕过此行为，而直接将其直接下载到磁盘?如果我需要使用WWW:Mechanize以外的其他功能，那我该如何使用WWW:Mechanize的cookie?

However this downloads the complete file into memory before dumping it to disk. How do you bypass this behavior, and simply download straight to disk? If I need to use something other than WWW:Mechanize then how would I go about using WWW:Mechanize's cookies with it?

推荐答案

您真正想要的是Mechanize :: Download

What you really want is the Mechanize::Download

http://mechanize.rubyforge.org/Mechanize/Download.html

您可以使用这种方式:

require 'mechanize'

agent = Mechanize.new
agent.pluggable_parser.default = Mechanize::Download
agent.get('http://example.com/foo').save('a_file_name')
