Question

我使用paperclip和amazon s3上传文件。我没有文件上传的任何问题。但是，当我尝试打开该文件时，我遇到以下错误。由于我是初学者，请向我建议解决方案。这是我的错误

PermanentRedirectThe bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.BCD25D22BDC4E922webtutorUbptlDdULmHVXgEPqp/JknHeGhsddn3zmw50a0GGRTCWMsEI/BTVHEK4SyeYrPIGwebtutor.s3.amazonaws.com

这是我的模特;

class Tutorial < ActiveRecord::Base
def self.search(search)
  search_condition = "%" + search + "%"
  find(:all, :conditions => ['tutorial_name ILIKE ? OR tutorial_discription ILIKE ?', search_condition, search_condition])
end

  attr_accessible :tutorial_date_release, :tutorial_discription, :tutorial_name, :tutorial_path, :tutorial_teacher_name, :avatar, :CategoryID, :TutorialType

  belongs_to :category

  has_many :comments, dependent: :destroy #relationship between comments and tutorials (if u delete a tutorials all comments will be deleted)

  scope :math, lambda{where(:CategoryID => 'Mathematics')}
  scope :reading, lambda{where(:CategoryID => 'Reading')}
  scope :writing, lambda{where(:CategoryID => 'Writing')}

  validates_presence_of :tutorial_date_release
  validates_presence_of :tutorial_discription
  validates_presence_of :tutorial_name
  #validates_presence_of :tutorial_teacher_name
  ###Paperclip
has_attached_file :avatar,:storage => :s3,
:s3_credentials => "#{Rails.root}/config/s3.yml",:path => ":attachment/:id.:extension",:bucket => 'webtutor'

#has_attached_file :avatar
 validates_attachment_content_type :avatar, :content_type => /.*/
end

这是我的show.html.erb

<% @page_title = "User Menu" %>
<header>
<%= render 'access/navigation' %>
</header>
<br/>
<br />
 <p> <b><center><font size="5"><%= @tutorial.tutorial_name  %></font></center></b></p>
<p><center><iframe 
      src="<%= @tutorial.avatar %>" style="width:800px; height:600px;" frameborder="5"/></iframe>

</center> </p>

<a href="<%= @tutorial.avatar %>" download="<%= @tutorial.avatar %>" >You can download this too!</a>

<br />
<%= link_to 'Back', tutorials_path %>
<br />
<h2> Comments </h2>
<div id="comments">
  <%= render :partial => @tutorial.comments.reverse %>
</div>

<%= form_for([@tutorial, Comment.new], remote: true) do |f| %>
   <p>
     <%= f.label :body, "New Comment" %><br />
     <%= f.text_area :body,:cols => "40", :rows => "1" %>
   </p>
   <p><%= f.submit "Add Comment" %></p>
<% end %>

S3.yml文件

development:
bucket: XXX
access_key_id: xx
secret_access_key: XX
test:
bucket: XX
access_key_id: XX
secret_access_key: XX
production:
bucket: XX
access_key_id: XX
secret_access_key: XX

首先，您需要从:bucket => 'webtutor'调用中删除 has_attached_file，因为它应该是您:s3_credentials中已设置的s3.yml的一部分。

此外，我建议您将 :url选项传递给has_attached_file。

定义has_attached_file如下：

has_attached_file :avatar,:storage => :s3,
:s3_credentials => "#{Rails.root}/config/s3.yml",
:path => ":attachment/:id.:extension", 
:url => ":s3_domain_url"

根据 RDoc for Module: Paperclip::Storage::S3

但在某些情况下，路径不起作用，你需要使用   domain-style（：s3_domain_url）。这里的任何其他东西都会被视为   路径样式。

注意：此选项的值是字符串，而不是符号。对：   ＆＃34;：s3_domain_url＆＃34;错误:: s3_domain_url

从amazon s3存储桶打开文件时出错
