首先让我说，我的AWS S3和Paperclip图片上传工作正常。下面的参考日志文件。
我花了太多时间试图跟踪Get Method返回403禁止的问题，看起来似乎是由于在文件名的末尾添加了一个扩展名。
我已经确认我可以通过直接在视图中对html源进行硬编码来连接存储在我的存储桶中的图像，例如http://mybucket_name.s3.amazonaws.com/..../filename。图像显示正常。
以下是代码设置：
我正在使用paperclip.rb
# config/initializers/paperclip.rb
Paperclip::Attachment.default_options[:url] = ':s3_domain_url'
Paperclip::Attachment.default_options[:path] = '/:class/:attachment/:id_partition/:style/:filename'
我正在使用aws.yml（利用aws-sdk）
#config/aws.yml
development:
access_key_id: xxxxxx
secret_access_key: xxxxxxxxxxxxxxxxx
production:
access_key_id: xxxxxx
secret_access_key: xxxxxxxxxxxxxxxx
在我的环境中：
.....
#config/environments/development.rb
# Path to ImageMagick
Paperclip.options[:command_path] = "/ImageMagick"
config.paperclip_defaults = {
:storage => :s3,
:s3_credentials => {
:bucket => 'mybucket_name'
}
}
....
我的Profile模型没什么特别之处。这是我用于回形针的内容：
....
#paperclip image attachment
has_attached_file :logo_image, :styles => { :medium => "250x250>", :small => "175x175>",
:thumb => "100x100>" }
# Validate content type
validates_attachment_content_type :logo_image, :content_type => /\Aimage/
# Validate filename
validates_attachment_file_name :logo_image, :matches => [/png\Z/, /jpe?g\Z/, /JPG?\Z/]
validates_attachment_size :logo_image, :less_than => 4.megabytes
....
配置文件控制器
#profiles_controller.rb
....
def create
@profile = Profile.new(profile_params)
if @profile.save
flash[:notice] = "Profile has been created."
redirect_to @profile
else
flash[:alert] = "Profile has not been created."
render "new"
end
end
def edit
end
def update
if @profile.update(profile_params)
redirect_to @profile
flash[:notice] = "Profile has been updated."
else
flash[:alert] = "Profile has not been updated."
render "edit"
end
end
def destroy
@profile.destroy
flash[:notice] = "Profile has been destroyed."
redirect_to profiles_path
end
private
def profile_params
params.require(:profile).permit(:id, :firstname, :lastname, :instagram, :company, :website,
:street_address, :city, :state, :zipcode, :phone, :logo_image, :address, :latitude,
:longitude,
:user_id, :user_email_id)
end
def set_profile
@profile = Profile.find(params[:id])
rescue ActiveRecord::RecordNotFound
flash[:alert] = "The profile you were looking for could not be found."
redirect_to profiles_path
end
用户模型（我通过用户模型构建profile_id）
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :confirmable
has_one :profile, :dependent => :destroy, autosave: true
accepts_nested_attributes_for :profile
after_create :build_profile
has_many :tags
def build_profile
Profile.create(user: self)
end
end
表单视图（标注：我没有使用multipart =＆gt;“true”）
....
<%= form_for @profile, :html => {"data-ajax" => false} do |f| %>
<p> </p>
[form code here ]
<div class="row">
<div class="col-md-4">
<%= f.file_field :logo_image %>
</div>
</div>
<p> </p>
<div class="row">
<div class="col-md-6">
<%= f.submit 'Save', :class =>
'btn btn-primary' %> <%= link_to "Cancel", :back, :class => 'btn btn-info' %>
查看以显示图像：
....
<div data-role="navbar">
<ul>
<li ><%= link_to "Offers", profile_path(@profile = current_user.profile), :data => {:icon=>"star"}
%></li>
<li><a href="/tags" data-icon="tag">Tags</a></li>
<li><%= link_to(edit_profile_path(@profile = current_user.profile)) do %>
<%= image_tag current_user.profile.logo_image.url, :class => "img-circle" %><br>
<%= "Account" %>
<% end %>
</li>
</ul>
</div>
这是图像更新的日志文件。正如您所见，AWS＆amp; Paperclip似乎正在做他们应该做的事情来删除旧图像和保存新图像。一切似乎都运转良好：
#log file

问题似乎是％3F1415584752被附加到文件名。我已经测试了AWS S3没有Paperclip，而是使用S3_Direct_Post和图像正确显示，没有奇怪的扩展并使用相同的AWS S3设置/凭证。但是，我想使用回形针。希望有人能指出我的解决方案。我猜它可能是愚蠢的。
当我访问AWS S3管理控制台时，图像正确保存在正确的文件夹结构和文件名中。
这是CORS设置。

我相信我通过执行以下操作解决了这个问题：
paperclip.rb初始化程序：
Paperclip::Attachment.default_options.merge!(
...
use_timestamp: false,
...)
