在Ruby代码中下载文件(Download file in Ruby code)

欣任何想法如何在Ruby中下载文件我试试这个但它不起作用

在我的index.html.erb中，我这样做

require 'open-uri' def index File.open('/target/path/to/downloaded.file', "wb") do |file| file.write open('http://example.com/your.file').read end end

但它仍然无法正常工作

Hin Any ideas how to download File in Ruby i try this but it's not working

最满意答案

send_file应该像这样工作：

send_file "/target/path/to/downloaded.file", :filename => "your.file",

还有一些可用的参数：

:type => :x_sendfile => true

send_file should work like this:

send_file "/target/path/to/downloaded.file", :filename => "your.file",

also there are a few more params available:

:type => :x_sendfile => true
