Question

我使用Rails 5在本地主机上构建网站，现在我想将图片上传到upyun服务器。但是使用下面的代码，我只得到图片网址：http://sssss-imgs.test.upcdn.net/img/img_name/00502fb437cb5ed9032f9393600578d8.png!320，而没有将图片上传到upyun服务器，因此无法打开图片，我的代码出了什么问题，有人帮忙吗？非常感谢！！

1。我的一些Gemfiles

gem 'carrierwave', '~> 1.2', '>= 1.2.2'
gem 'carrierwave-upyun', '~> 0.2.2'

2。我的config/initializers/carrierwave.rb，（这是新添加的内容）

require "carrierwave"
require "carrierwave/validations/active_model"
CarrierWave.configure do |config|
  config.storage = :upyun
  config.remove_previously_stored_files_after_update = false
  config.upyun_username = "sssss"
  config.upyun_password = "ssssss123"
  config.upyun_bucket = "sssss-imgs"
  config.upyun_bucket_domain = "http://sssss-imgs.test.upcdn.net"
  config.upyun_api_host = "http://v0.api.upyun.com"
end

3。我的BaseUploader

IMAGE_UPLOADER_ALLOW_IMAGE_VERSION_NAMES = %(320 640 800)
class BaseUploader < CarrierWave::Uploader::Base
  storage :upyun
  def store_dir
    "#{model.class.to_s.underscore}/#{mounted_as}"
  end

  def extension_white_list
    %w[jpg jpeg gif png svg]
  end


  def url(version_name = "")
    @url ||= super({})
    version_name = version_name.to_s
    return @url if version_name.blank?
    if not version_name.in?(IMAGE_UPLOADER_ALLOW_IMAGE_VERSION_NAMES)

      raise "ImageUploader version_name:#{version_name} not allow."
    end
    [@url,version_name].join("!") 
  end

end

4。我的ImgUploader

class ImageUploader < BaseUploader

  def filename
    if original_filename
      @name||=Digest::MD5.hexdigest(File.dirname(current_path))
      "#{@name}.#{file.extension}"
    end
  end
end

5。我的img.rb

模型

class Img < ActiveRecord::Base
  mount_uploader :img_name, ImageUploader
end

6。我的imgs_controller.rb的管理员

class ImgsController < ApplicationController

  def index
    @imgs = Img.all
  end

  def show
    @img = Img.find(params[:id])
  end

  def new
    @img = Img.new
  end

  def create
    @img = Img.new(img_params)
    @img.save
    redirect_to @img
  end

  def destroy
    @img.destroy
    render :index
  end

  private

  def img_params
    params.require(:img).permit!
  end
end

7。我的img new.html.erb和show.html.erb

## new.html.erb
<%= form_for @img do |f| %>
  <%= f.file_field :img_name %>
  <%= f.submit "upload" %>
<% end %>


## show.html.erb

<%= image_tag(@img.img_name.url("320")) %>

8。我对img的迁移

class CreateImgs < ActiveRecord::Migration[5.2]
  def change
    create_table :imgs do |t|
      t.string :img_name
      t.timestamps null: false
    end
  end
end

非常感谢您的回答，这个问题困扰了我好几天了。
