通过 Carrierwave 和 Fog 上传文件时出现 Exconn::Errors::SocketError

这是我最近遇到的问题的延续 -堆栈级别太深错误 - 我认为是由强参数产生的

每当我做一个Post创建，其中涉及文件上传，我收到此错误：

Excon::Errors::SocketError - Broken pipe:

My Post模型看起来像这样：

# == Schema Information
#
# Table name: posts
#
#  id         :integer          not null, primary key
#  status     :string(255)
#  title      :string(255)
#  date       :datetime
#  photo      :string(255)
#  body       :text
#  created_at :datetime
#  updated_at :datetime
#  user_id    :integer

#

class Post < ActiveRecord::Base
  has_ancestry
  belongs_to :user
  resourcify

  mount_uploader :photo, ImageUploader
  mount_uploader :file, FileUploader
end

我的控制器看起来像这样：

  def create
    @post = current_user.posts.new(post_params)

    respond_to do |format|
      if @post.save
        format.html { redirect_to @post, notice: 'Post was successfully created.' }
        format.json { render :show, status: :created, location: @post }
      else
        format.html { render :new }
        format.json { render json: @post.errors, status: :unprocessable_entity }
      end
    end
  end

  private
    # Never trust parameters from the scary internet, only allow the white list through.
    def post_params
      params.require(:post).permit(:status, :title, :date, :photo, :body, :parent_id)
    end

这是我的image_uploader.rb:

# encoding: utf-8

class ImageUploader < CarrierWave::Uploader::Base
  include CarrierWave::RMagick
  storage :fog

  include CarrierWave::MimeTypes
  process :set_content_type

  def store_dir
    "images/#{model.id}-#{model.created_at}"
  end

  version :thumb do
    process :resize_to_fit => [80, 80]
  end

  version :large do
    process :resize_to_limit => [400, 400]
  end

  def extension_white_list
    %w(jpg jpeg gif png)
  end

end

这是我的 Gemfile：

这是我的上传表单部分：

<%= simple_form_for @post do |f| %> 
    <%= f.error_notification %>

    <%= f.input :parent_id, as: :hidden %>

    <% if can? :manage, @post %>
      <%= f.input :status, collection: Status.all %>
    <% end %>       

    <%= f.input :title %><br />
    <%= f.input :date %><br />      
    <%= f.input :photo %><br />
    <%= f.input :body %><br />      

  <%= f.button :submit %>

<% end %>

这是我的config/carrierwave.rb file:

CarrierWave.configure do |config|
  config.fog_credentials = {
    provider:               'AWS',
    region:                 'us-east-1',                          
    aws_access_key_id:      ENV["AWS_ACCESS_KEY"],         
    aws_secret_access_key:  ENV["AWS_SECRET_ACCESS_KEY"],         
  }
  config.fog_directory  = ENV["AWS_MY_BUCKET"]       
end

有什么想法可能导致这种情况吗？

Update 1

这是更多调试信息。一旦我删除了图像大小的调整，该套接字错误消息就会消失。

但这是我得到的新错误：

我认为这可能与当地环境有关。

这是一个使用 s3 的例子，但想法是一样的。they说以下内容：

我最近在我的网站上工作，在通过 Carrierwave/Fog 上传较大文件（如 1.8M）到 S3 时遇到问题。我收到以下错误：Excon::Errors::SocketError（管道损坏（Errno::EPIPE））：

我发现需要在 Carrierwave.rb 初始化程序文件中设置区域代码才能上传较大的文件。显然，它默认使用除我使用的区域代码之外的某些区域代码，并且由于某种原因，在上传较大文件时会导致错误。

要查找区域代码，请通过 S3 导航到已存储的实际文件，单击该文件，然后单击屏幕右上角的“属性”。您将看到类似以下内容的链接：

在这种情况下，以下是您应在配置中设置的区域代码：us-west-2
