Ruby on Rails:上传到AWS-S3时，如何解决"Digest::Digest is deprecated；use Digest“警告？

Question

我正在尝试制作一个应用程序，用户可以上传，下载和流媒体音乐到亚马逊网络服务，简单存储服务(AWS-S3)。

我正在尝试解决的一个问题是，当我尝试上传MP3文件时，我在终端中收到一条警告，在我被重定向并警告用户“无法完成上传”之前，该警告恰好重复了四次。当我在upload方法中对我的AWS对象使用.store方法时，我得到"Digest::Digest is deprecated；use Digest“警告。

有没有其他人处理过这种情况，可能会帮助我？非常感谢，非常感谢。

这是我的控制器：

类SongsController < ApplicationController

  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

当我试图上传一个文件时，我的终端里发生了这样的事情：

Answer 1

你有没有试过确保你有一个最新版本的gem？

检查您的gemfile：

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

Answer 2

在阅读了由亚马逊网络服务提供的文档后，我找到了在我的亚马逊网络服务3对象AWS::S3::S3Object上调用的正确方法。Here，它说明我必须在我的AWS::S3::S3Object上使用.write方法。

根据文档，我的问题得到了解决，我不再收到重复的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。在我的例子中，存储桶的区域是俄勒冈州，端点是's3-us-west-2.amazonaws.com‘Regions and Endpoints
