Question

我正在尝试使用回形针使用AmazonS3为我的博客存储图像。该博客设计了用于登录/注册[User]的gem，我想通过将每个用户存储在Amazon S3上来添加图像。以前，我将它们存储在数据库中，并且运行良好。

我已经搜索了很多，但是找不到解决方法。

        //Development.rb
    config.paperclip_defaults = {
      storage: :s3,
        s3_credentials: {
          bucket: ENV.fetch('S3_BUCKET_NAME'),
          access_key_id: ENV.fetch('AWS_ACCESS_KEY_ID'),
          secret_access_key: ENV.fetch('AWS_SECRET_ACCESS_KEY'),
          s3_region: ENV.fetch('AWS_REGION'),
        }
      }

    //AddAttachment Migration
    class AddAttachmentImageToUsers < ActiveRecord::Migration[5.2]
      def self.up
        change_table :users do |t|
          t.attachment :image
        end
      end

      def self.down
        remove_attachment :users, :image
      end
    end

    //User.rb
    class User < ActiveRecord::Base
      # Include default devise modules. Others available are:
      # :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
      devise :database_authenticatable, :registerable,
             :recoverable, :rememberable, :validatable

      has_many :comments, dependent: :destroy
      has_many :likes, dependent: :destroy
      has_many :articles

      has_attached_file :image, :styles => { :medium => "300x300>", :thumb => "100x100>"}

      validates_attachment_content_type :image, content_type: /\Aimage\/.*\z/
    end

    //Application.yml
    AWS_ACCESS_KEY_ID: -----
    AWS_SECRET_ACCESS_KEY: ------
    S3_BUCKET_NAME: -------------
    AWS_REGION: ap-south-1

与以下问题类似：https://railsblogs.rohityadav.in/2018/01/awss3errorsaccessdenied-access-denied.html

如果在尝试上传到S3时遇到此错误，则需要为此IAM用户分配“ AmazonS3FullAccess”策略。

或者可能是heroku配置出现问题：

AWS::S3::Errors::AccessDenied. Cannot save to S3 with Ruby on Rails

您需要将AWS凭证设置为heroku中的配置变量（基本上是环境变量）。您可以检查是否已使用heroku config设置它们；如果未设置，则可以使用heroku config添加它们：set S3_BUCKET_NAME = AWS_ACCESS_KEY_ID =任何AWS_SECRET_ACCESS_KEY = something_secret。 heroku config --help
