无法将图像上传到AWS S3中的存储桶中

Question

我有一个场景，其中上传的照片必须存储在AWS S3存储桶中，并通过电子邮件调用图像，但在无法存储Rails和相应的宝石升级后S3中的图像。我将aws-s3版本从0.6.1升级到0.6.3，aws-sdk从1.3.5升级到1.3.9，right_aws从3.0.0升级到3.0.5，最后将Rails从3.2.1升级到4.2.6。

我已经通过put命令进行了测试，它将使用所有方法，但是我怀疑@type上的上传方法是否有任何语法更改（这里@type是2个存储桶名称photo_screenshots和indicator_screenshots）。 请帮帮我。

这是我的lib/screenshot.rb：

class Screenshot 
     attr_reader :user_id, :report_id, :type 

     def initialize(user_id, report_id, type) 
      @user_id, @report_id, @type = user_id, report_id, type 
      capture 
      resize(500, 686) if @type == 'report_screenshots' 
      upload 
      delete_local_copy 
     end 

     def capture 
     if Rails.env.production? 
      phantom = Rails.root.join('vendor/javascripts/phantomjs_linux/bin/phantomjs') 
      url  = Rails.application.config.custom.domain_url + "users/#{@user_id}/reports/#{@report_id}" 
     end 
     js   = Rails.root.join("vendor/javascripts/#{@type}.js") 
     image  = Rails.root.join("public/#{@type}/#{@report_id}.png") 

     `/bin/bash -c "DISPLAY=:0 #{phantom} #{js} #{url} #{image}"` 
     end 

     def resize(width, height) 
     path = "public/#{@type}/#{@report_id}.png" 
     img = Magick::Image::read(path).first 
     #img.thumbnail!(width, height) 
     img.change_geometry("#{width}x#{height}") do |cols, rows, img| 
      img.thumbnail!(cols, rows) 
     end 
     img.write(path) 
     end 

     def upload 
     file_name = Rails.root.join("public/#{@type}/#{@report_id}.png") 
     s3config = YAML.load_file(Rails.root.join('config', 's3.yml'))[Rails.env] 
     s3 = RightAws::S3.new(s3config["access_key_id"], s3config["secret_access_key"]) 
     @type == 'report_screenshots' ? s3.bucket("my_project.#{Rails.env}", true).put("#{@type}/#{@report_id}.png", File.open(file_name), {}, 'public-read', { 'content-type' => 'image/png' }) : s3.bucket("my_project.#{Rails.env}", true).put("indicator_screenshots/#{@report_id}.png", File.open(file_name), {}, 'public-read', { 'content-type' => 'image/png' }) 
     report = Report.find(@report_id) 
     @type == 'report_screenshots' ? report.update_attribute(:report_screenshot_at, Time.now) : report.update_attribute(:indicator_screenshot_at, Time.now) 
     end 

     def delete_local_copy 
     file_name = Rails.root.join("public/#{@type}/#{@report_id}.png") 
     File.delete(file_name) 
     end 

     def self.delete_s3_copy(report_id, type) 
     s3config = YAML.load_file(Rails.root.join('config', 's3.yml'))[Rails.env] 
     s3 = RightAws::S3.new(s3config["access_key_id"], s3config["secret_access_key"]) 
     s3.bucket("my_project.#{Rails.env}").key("#{type}/#{report_id}.png").delete 
     end 


end 

每当我点击发送一封电子邮件，这是发生了什么：

控制器：

def send_test_email 
    if @report.photos.empty? 
     Rails.env.development? ? Screenshot.new(@user.id, @report.id, Rails.application.config.custom.indicator_screenshot_bucket) : Screenshot.delay.new(@user.id, @report.id, Rails.application.config.custom.indicator_screenshot_bucket) 
    else 
     Rails.env.development? ? Screenshot.new(@user.id, @report.id, "photo_screenshots") : Screenshot.delay.new(@user.id, @report.id, "photo_screenshots") 
    end 
    ReportMailer.delay.test_report_email(@user, @report) 
    respond_to do |format| 
     format.json { render :json => { :success => true, :report_id => @report.id, :notice => 'Test email was successfully sent!' } } 
    end 
    end

您可以尝试上传一个更简单的方法。

将图像上传到具有不同文件夹的固定存储桶，用于每个对象或应用程序。s3保留存储桶创建次数的限制，而存储桶内的内容不存在限制。

此代码将使用aws-sdk gem将用户的图像上传到s3。上传的图片和图片将公开 ，以便上传的图片可以直接访问。所需的输入是图像完整路径 ，它存在的位置，应该上传的文件夹以及要上传的应用程序 的user_id。

  def save_screenshot_to_s3(image_location, folder_name,user_id) 
       service = AWS::S3.new(:access_key_id => ACCESS_KEY_ID, 
            :secret_access_key => SECRET_ACCESS_KEY) 
       bucket_name = "app-images" 
       if(service.buckets.include?(bucket_name)) 
       bucket = service.buckets[bucket_name] 
       else 
       bucket = service.buckets.create(bucket_name) 
       end 
       bucket.acl = :public_read 
       key = folder_name.to_s + "/" + File.basename(image_location) 
       s3_file = service.buckets[bucket_name].objects[key].write(:file => image_location) 
       s3_file.acl = :public_read 
       user = User.where(id: user_id).first 
       user.image = s3_file.public_url.to_s 
       user.save 
      end  

处理的截图部分，在您的捕获方法，你必须使用做了这样的事情。

`/bin/bash -c "DISPLAY=:0 #{phantom} #{js} #{url} #{image}"` 

是在/斌/庆典真正需要的事情，将其更改为下面的代码，它应该工作。

 `DISPLAY=:0 "#{phantom}" "#{js}" "#{url}" "#{image}"` 

让它成为，如果它打破别的东西。 由于您知道最终图像位置是图片。直接传递给save_screenshot_to_s3，你应该可以保存它。如果按照方法
