Using send_file in rails
提问by sgi
I'm sending a ms-word file using rails. i.e when I click on a link, a doc file from tmp folder (in project) is sent.
我正在使用 rails 发送一个 ms-word 文件。即，当我单击链接时，会发送来自 tmp 文件夹（在项目中）的 doc 文件。
The code I'm using is
我正在使用的代码是
@filename ="#{RAILS_ROOT}/tmp/test/test.doc"
send_file(@filename ,
:filename => "test",
:type => 'application/msword',
:disposition => 'attachment',
:streaming => 'true',
:buffer_size => '4096')
It's working, but it's sending an empty file. Content is missing in the file. Any suggestions?
它正在工作，但它正在发送一个空文件。文件中缺少内容。有什么建议？

There is no send_file:streaming option, it is :stream. You're passing bad parameters types. :buffer_size should be number, not a string. :stream should be boolean, not string.
没有send_file:streaming 选项，它是 :stream。您正在传递错误的参数类型。:buffer_size 应该是数字，而不是字符串。:stream 应该是布尔值，而不是字符串。
:stream => true,
:buffer_size => 4096,
You need only filename parameter (if you want to send file with another name than the original). Other options you are using are default (except :type).
您只需要 filename 参数（如果您想发送与原始名称不同的文件）。您使用的其他选项是默认的（除了 :type）。
Can you try this ?
你能试试这个吗？
@filename ="#{RAILS_ROOT}/tmp/test/test.doc"
send_file(@filename, :filename => "test.doc")

comment out the following line in config/environments/production.rb
注释掉以下行 config/environments/production.rb
config.action_dispatch.x_sendfile_header = "X-Sendfile"

In your view =>
<%= link_to "click here to download", signed_feeds_pdf_path(:feed_image_path => feed_image.feedimage.path), target: '_self' %>
In your controller =>
def pdf
file_name = params[:feed_image_path].split('/').last
@filename ="#{Rails.root}/public/uploads/feed_image/feedimage/#{file_name}"
send_file(@filename ,
:type => 'application/pdf/docx/html/htm/doc',
:disposition => 'attachment')
end

Try sending with :disposition => 'inline'
尝试使用 :disposition => 'inline' 发送
send_file path, :type => 'application/msword', :disposition => 'inline'
