Question

我有一个Photo模型，我正在运行paperclip (>= 3.4.0)，ruby 2.3.7，Rails 3.2。

在我的photo.rb中，我有以下内容：

class Photo < ActiveRecord::Base
  attr_accessible :position, :source_uri, :img, :published

  belongs_to :property

  has_attached_file :img,
    :styles => { :large => "590x380>", :medium => "380x200>", :small => "280x150>", :thumb => "100x75>" },
    :url => "#{:source_uri}" 

  def source_uri=(uri)
    self.img_file_name = "#{random_base_name}#{ext_from_mime}"
    super
  end

  def source_uri
    URI.unescape(super)
  end

在我的config/environments/production.rb中，我有这个：

  config.paperclip_defaults = {
    :storage => :s3,
    :bucket => ENV['MY_S3_BUCKET'],
    :path => "uploads/myapp/:class/:attachment/:id/:style/:filename",
    :s3_credentials => "#{Rails.root}/config/aws.yml",
    :default_url => ":attachment/:class/:style/missing.png"
  }

在我的aws.yml中，我有以下内容：

development:
  access_key_id:
  secret_access_key:
  bucket:

staging:
  access_key_id: <%= ENV["S3_ACCESS_KEY_ID"] %>
  secret_access_key: <%= ENV["S3_SECRET_ACCESS_KEY"] %>
  bucket: <%= ENV["S3_BUCKET"] %>

production:
  access_key_id: <%= ENV["MY_S3_ACCESS_KEY_ID"] %>
  secret_access_key: <%= ENV["MY_S3_SECRET_ACCESS_KEY"] %>
  bucket: <%= ENV["MY_S3_BUCKET"] %>

当我上传图片时，它似乎可以根据日志进行工作：

  SQL (0.7ms)  INSERT INTO "photos" ("created_at", "featured", "img_content_type", "img_file_name", "img_file_size", "img_fingerprint", "img_updated_at", "position", "property_id", "published", "source_uri", "updated_at") VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10, $11, $12) RETURNING "id"  [["created_at", Sat, 25 May 2019 05:52:17 UTC +00:00], ["featured", nil], ["img_content_type", nil], ["img_file_name", "65798ASDASD4"], ["img_file_size", nil], ["img_fingerprint", nil], ["img_updated_at", nil], ["position", nil], ["property_id", 18713], ["published", true], ["source_uri", "https://s3-us-west-2.amazonaws.com/propbmedia/BenjaminJohnson/31680-1.jpg"], ["updated_at", Sat, 25 May 2019 05:52:17 UTC +00:00]]
   (0.9ms)  COMMIT

但是，如果我要在控制台中四处浏览，将会得到以下信息：

irb(main):027:0> q.photos.first.source_uri
  Photo Load (11.2ms)  SELECT "photos".* FROM "photos" WHERE "photos"."property_id" = 16759 ORDER BY position ASC LIMIT 1
=> "https://s3-us-west-2.amazonaws.com/propbmedia/BenjaminJohnson/10192-16.jpg"
irb(main):028:0> p.photos.first.source_uri
=> "https://s3-us-west-2.amazonaws.com/propbmedia/BenjaminJohnson/33449-7.jpg"
irb(main):029:0> q.photos.first.img.url
  Photo Load (8.2ms)  SELECT "photos".* FROM "photos" WHERE "photos"."property_id" = 16759 ORDER BY position ASC LIMIT 1
=> "http://s3.amazonaws.com/johnson-benjamin/uploads/hojo/photos/imgs/208532/original/9086718487708773"
irb(main):030:0> p.photos.first.img.url
=> "http://s3.amazonaws.com/johnson-benjamin/uploads/hojo/photos/imgs/241108/original/7782737090666986"

请注意，最后一个代码段中的前两个URL有效，但最后2个返回“访问被拒绝”错误。

我还尝试使用Comfy CMS将头像上传到S3，并且有效。当然，我不认为这是由Paperclip管理的（我可能错了），但是由于某种原因，它会将其上传到其他地方。这是可以使用的头像的示例网址-http://s3.amazonaws.com/johnson-benjamin/uploads/hojo/agents/avatars/21/large/10PP-COMING-SOON.jpg?1558767320

那么我的主要property.photos模型可能出什么问题了？

那是为什么？

也许您需要配置存储桶以允许跨源请求，创建CORS配置，这是一个XML文档，其中包含用于标识可以访问存储桶的源的规则，支持每个源的操作（HTTP方法）以及其他具体信息的操作。

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<CORSRule>
    <AllowedOrigin>*</AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
    <MaxAgeSeconds>3000</MaxAgeSeconds>
    <AllowedHeader>Authorization</AllowedHeader>
</CORSRule>
<CORSRule>
    <AllowedOrigin>*</AllowedOrigin>

为什么我的回形针配置不起作用？
