我正在使用Paperclip和aws-sdk gems创建rails API应用程序。
该应用将URL保存为字符串。保存的网址如下。
http://s3.amazonaws.com/S3_BUCKET_/profiles/avatars/000/000/001/original/avatar.png?1457514823
我无法打开上面的图片。因为从s3中获取它的URL是以下
http://S3_BUCKET_/s3.amazonaws.com//profiles/avatars/000/000/001/original/avatar.png?1457514823
看看水桶是如何成为第一个?但是保存在数据库中的url有第二个桶吗?如何更改保存的URL以使存储桶成为第一个?
config/initializers/paperclip.rb
Paperclip::Attachment.default_options.update(
default_url: "https://#{Rails.application.secrets.bucket}.s3-ap-southeast-2.amazonaws.com/" \
"/profiles/avatars/default/missing.jpg")
config/aws.yml
development: &defaults
access_key_id: s3_access_key
secret_access_key: s3 secret key
s3_region: ap-southeast-2
test:
secret_access_key: s3 secret key
staging:
<<: *defaults
access_key_id: s3_access_key
secret_access_key: <%= ENV["SECRET_KEY_BASE"] %>
production:
<<: *defaults
access_key_id: s3_access_key
secret_access_key: <%= ENV["SECRET_KEY_BASE"] %>
profile.rb it has the attachment saved
require "base64"
class Profile < ActiveRecord::Base
belongs_to :user
validates :user, presence: true
has_attached_file :avatar, styles: { thumb: "100x100>" }
validates_attachment_content_type :avatar, content_type: /image/i
def avatar_url
avatar && avatar.url
end
def avatar_base64=(image_base64)
file = Paperclip.io_adapters.for(image_base64)
file.original_filename = file.content_type.sub("image/", "avatar.")
self.avatar = file
end
答案 0 :(得分:1)
您可以在config/initializers/paperclip.rb
中添加默认网址,如下所示:
Paperclip::Attachment.default_options[:url] = ':s3_domain_url'
或者您可以直接在您的环境配置中进行配置,即config/environments/production.rb
:
config.paperclip_defaults = {
storage: :s3,
url: ':s3_domain_url',
...
}
重要注意:s3_domain_url
是字符串,而不是符号。
