如何在Amazon S3上打开文件并进行身份验证？

我知道如何用回形针执行此操作，但是在打开文件时如何完成？

我的助手

            File.open("#{RAILS_ROOT}/public/xml/#{output}.xml", "w") do |f|

               f.puts("<?xml version='1.0' encoding='UTF-8'?>")            
               f.puts("<site>")     

               f.puts("<general name='general' type='general'><imagePath>photographer/image/</imagePath><moviePath>../photographer/flv/</moviePath></general>")             
               f.puts("#{xmlmenu.to_xml}")
               f.puts("#{xmlmovies.to_xml}")                           
               f.puts("#{xmltextpages.to_xml}")

               f.puts("</site>")
            end

更新

 My helper file:
    module Admin::XmlHelper
    require 'builder'
    require 'aws/s3'

    def update_xml(output) 
        AWS::S3::Base.establish_connection!(
        :access_key_id     => 'mykey',
        :secret_access_key => 'mykey'
      )

    file = "xml/#{output}.xml"

    content = "#{
                   f.puts("<?xml version='1.0' encoding='UTF-8'?>")            
                   f.puts("<site>")     
                   f.puts("<general name='general' type='general'><imagePath>photographer/image/</imagePath><moviePath>../photographer/flv/</moviePath></general>")             
                   f.puts("#{xmlmenu.to_xml}")
                   f.puts("#{xmlmovies.to_xml}")                           
                   f.puts("#{xmltextpages.to_xml}")
                   f.puts("</site>")}"

    AWS::S3::S3Object.store(file, content, "mybucket", :access => :public_read)

        end         

    end

我在视图中收到错误：

uninitialized constant AWS::S3::Base

更新

而不是gem "aws-s3"

应该是：gem 'aws-s3', :require => 'aws/s3'

Answer 1

您的问题是如何将文件写入S3？如果是这样，使用aws-s3 gem，你会这样做：

AWS::S3::Base.establish_connection!(
  :access_key_id => MY_ACCESS_KEY,
  :secret_access_key => MY_SECRET_ACCESS_KEY
 )

 content = "this is the content";

AWS::S3::S3Object.store("any_file_name.html", content, "my_bucket_name", :access => :public_read)

Answer 2

为什么不使用aws-s3 gem？

Ruby和Amazon S3如何打开文件并进行身份验证？
