我正在使用Uploadify 2.1.4和rails 2.3.8。我正在尝试应用FlashSessionCookieMiddleware修复程序,该修复程序应该在uploadify的基于闪存的请求期间维护会话信息。在阅读了其中一些指南后,我已应用此修复程序:
但是,我的会话信息仍未被转移。以下是我的应用配置:
# 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] %>'}
我的中间件代码正常加载,以下是 rake中间件显示的内容:
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,我尝试测试上一个请求是否有有效的会话/ cookie信息:
# In Controller
logger.info "Session: #{session.inspect}"
在log / development.log中只打印一个空哈希:
Session: {}
[嗅]任何人都可以看到我做错了吗?

我能够通过此处发布的步骤在{2.3}中使用http://railstips.org/blog/archives/2009/07/21/uploadify-and-rails23/
我唯一需要修改的是flash_session_cookie_middleware.rb到以下内容:
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
