Question

我正在尝试创建一个应用程序，用户可以上传，下载和流式传输音乐到Amazon Web Services，简单存储服务（AWS-S3）。

我试图解决的一个问题是，当我尝试上传MP3文件时，我在终端中收到一个警告，在我被重定向之前重复四次，并向用户发出警告＆＃34;无法＆＃34; 39;完成上传＆＃34;。我得到了##;摘要::摘要已被弃用;使用摘要＆＃34;我在上传方法中的AWS对象上使用.store方法时发出警告。

还有其他人处理过这种情况并且可以帮助我吗？非常感谢，非常感谢。

这是我的控制者：

class SongsController＆lt; ApplicationController中

  BUCKET = 'batana_application'

  def index
    @songs = AWS::S3::Bucket.find(BUCKET).objects
  end

  def upload
    begin
      AWS::S3::S3Object.store(sanitize_filename(params[:mp3file].original_filename), params[:mp3file].read, BUCKET, :access => :public_read)
      redirect_to root_path
    rescue
      render :text => "Couldn't complete the upload"
    end
  end

  def delete
    if (params[:song])
      AWS::S3::S3Object.find(params[:song], BUCKET).delete
      redirect_to root_path
    else
      render :text => "No song was found to delete!"
    end
  end

  private

  def sanitize_filename(file_name)
    just_filename = File.basename(file_name)
    just_filename.sub(/[^\w\.\-]/,'_')
 end

end

这是我尝试上传文件时终端中发生的事情：

Answer 1

您是否尝试过确保拥有最新版本的宝石？

检查你的gemfile：

gem "aws-sdk", "~> 1.33.0"

Answer 2

阅读文档后，我设法找到，由AWS提供，我找到了调用我的AWS-S3对象AWS::S3::S3Object的正确方法。 Here，它声明我必须在AWS::S3::S3Object上使用.write方法。

在文档之后，我的问题已经解决，我再也没有收到重复的Digest::Digest is deprecated; use Digest警告。

Answer 3

我通过在application.rb中添加AWS :: S3 :: DEFAULT_HOST.replace（'s3-us-west-2.amazonaws.com'）解决了这个问题。在我的情况下，桶的区域是俄勒冈州，端点是's3-us-west-2.amazonaws.com'Regions and Endpoints

Ruby on Rails：如何在上传到AWS-S3时解决“Digest :: Digest已弃用;使用摘要”警告？
