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')
