Uploadify，Flash会话和Rails 2.3.8

Question

我正在使用Uploadify 2.1.4和rails 2.3.8。我试图应用FlashSessionCookieMiddleware修复程序，该修复程序应该在uploadify的基于Flash的请求期间维护会话信息。我读了一些这些指南的应用后，此修复程序：

• Flash uploaders, Rails, cookie based sessions and CSRF: Rack Middleware to the rescue!

• Uploadify on Rails with Paperclip

然而，我的会话信息仍然没有被结转。下面就来看看，在我的应用程序配置：

# config/environment.rb 

config.load_paths += %W(#{RAILS_ROOT}/config/middleware) 

...

# config/middleware/flash_session_cookie_middleware.rb 

require 'rack/utils' 

class FlashSessionCookieMiddleware 
    def initialize(app, session_key = '_session_id') 
    @app = app 
    @session_key = session_key 
    end 

    def call(env) 
    if env['HTTP_USER_AGENT'] =~ /^(Adobe|Shockwave) Flash/ 
     params = ::Rack::Utils.parse_query(env['QUERY_STRING']) 
     env['HTTP_COOKIE'] = [ @session_key, params[@session_key] ].join('=').freeze unless params[@session_key].nil? 
    end 
    @app.call(env) 
    end 
end 

ActionController::Dispatcher.middleware.insert_before(ActionController::Base.session_store, FlashSessionCookieMiddleware, ActionController::Base.session_options[:key]) 

...

// My Uploadify JS 
'fileDataName' : 'file', 
'queueID'  : 'fileQueue', 
'auto'   : true, 
'multi'   : true, 
'method'   : 'get', 
'scriptData'  : { session_key: '<%= request.session_options[:key] %>'} 

我中间件代码加载正确的，下面是耙中间件显示：

use Rack::Lock 
use ActionController::Failsafe 
use FlashSessionCookieMiddleware, "_my_app_session" 
use ActiveRecord::ConnectionAdapters::ConnectionManagement 
use ActiveRecord::QueryCache 
use ActiveRecord::SessionStore, #<Proc:0xb7176760@(eval):8> 
use ActionController::ParamsParser 
use Rack::MethodOverride 
use Rack::Head 
use ActionController::StringCoercion 
run ActionController::Dispatcher.new 

然后，我尝试测试了，如果最后一个请求具有有效的会话/ cookie的信息：

# In Controller 
logger.info "Session: #{session.inspect}" 

其中在日志/ development.log只打印一个空的哈希：

Session: {} 

[嗅探]任何人都可以看到我做错了什么？

Answer 1

我能得到这个有台阶上2.3.8上班张贴在这里：http://railstips.org/blog/archives/2009/07/21/uploadify-and-rails23/

我唯一能做的修改是flash_session_cookie_middleware.rb以下几点：

require 'rack/utils' 

class FlashSessionCookieMiddleware 
    def initialize(app, session_key = '_session_id') 
    @app = app 
    @session_key = session_key 
    end 

    def call(env) 
     if env['HTTP_USER_AGENT'] =~ /^(Adobe|Shockwave) Flash/ 
     @session_key = ActionController::Base.session_options[:key] 
     req = Rack::Request.new(env) 
     unless req.params[@session_key].nil? 
      env['HTTP_COOKIE'] = "#{@session_key}=#{req.params[@session_key]}".freeze 
     end 
     end 

     @app.call(env) 
    end 
end
