我正在构建一个 Rails 应用程序来测试我们的旗舰产品(也是基于 Web 的)。问题是部分测试需要使用生产应用程序的 Web 界面来上传文件。所以我需要做的是让 rails 应用程序将这些文件上传到生产应用程序(而不是 rails)。有没有办法让 Rails 将文件发布到生产应用程序(就像浏览器将文件发布到生产应用程序一样)?

If you just need to upload files, I think it's pointless to use a plugin for this. File upload is very, very simple.

class Upload < ActiveRecord::Base
  before_create :set_filename
  after_create :store_file
  after_destroy :delete_file

  validates_presence_of :uploaded_file

  attr_accessor :uploaded_file

  def link
    "/uploads/#{CGI.escape(filename)}"
  end

  private

  def store_file
    File.open(file_storage_location, 'w') do |f|
      f.write uploaded_file.read
    end
  end

  def delete_file
    File.delete(file_storage_location)
  end

  def file_storage_location
    File.join(Rails.root, 'public', 'uploads', filename)
  end

  def set_filename
    self.filename = random_prefix + uploaded_file.original_filename
  end

  def random_prefix
    Digest::SHA1.hexdigest(Time.now.to_s.split(//).sort_by {rand}.join)
  end
end

Then, your form can look like this:

<% form_for @upload, :multipart => true do |f| %>
  <%= f.file_field :uploaded_file %>
  <%= f.submit "Upload file" %>
<% end %>

I think the code is pretty much self explanatory, so I won't explain it ; )

当然,使用 net/http 库...

http://www.ruby-doc.org/stdlib/libdoc/net/http/rdoc/classes/Net/HTTP.html

但它似乎缺少多部分编码,因此请查看另一篇文章

看看这个类似的问题

您可能想查看 Paperclip 插件。非常适合上传图片。也可能适用于其他格式。

Paperclip gem 确实是一个解决方案。它也适用于其他格式,并且很容易在 Rails 中实现。看视频..!!
