ruby-on-rails - 发送 csv/xls 文件时的 ActionController::Session::CookieStore::CookieOverflow - rails 2.3.5

Question

我有一个页面，上面有一个大图表，当你使用它时，url 中有很多参数。

所以我的控制器看起来像这样：

def report
   # gather data for report

   respond_to do |format|
      format.html
      format.xls { send_xls_file(@campaigns.uniq) }
      format.csv { send_csv_file(@campaigns.uniq)}
   end

  def send_xls_file(campaigns)
    @campaigns = campaigns
    report_name = "CampaignReport.xls"
    response.headers["Content-Disposition"] = "attachment; filename=#{report_name}"
  end

  # send csv does is similar but creates a csv using fastercsv.

在 xls 的视图中，我创建了 excel 文档

现在，当我在页面上有一个很长的 url 并调用 xls 或 csv 时，我收到此错误：

我不是故意在我的会话中存储任何东西，似乎 rails 可能将 url 放入会话中并且它太大了？有任何想法吗？

您可以考虑将会话存储移动到 ActiveRecord 而不是 cookie。如果您对当前.xls处理的实现感到满意，那将是一个简单的修复。问题在于 cookie 存储空间有限：4 kb。

如果您决定迁移到 ActiveRecord 会话存储，请执行以下步骤：

在您的app/config/initializers/session_store.rb文件中将商店更改为:active_record_store
那么你应该rails generate session_migration和rake db:migrate

您可能会想到另一种会话存储：Memcache。它速度更快，在某些情况下使用起来更舒适。

看起来有些东西正在会话中存储长 url - 可能清除？- 这导致了你的问题。

错误消息清楚地表明 cookie 存储大小溢出的问题。

您的会话（默认在 cookie 中）需要移动到活动记录存储或内存缓存存储以解决此问题。

对于数据库会话：

config.action_controller.session_store = :active_record_store

您需要创建会话表，如下所示

rake db:sessions:create
rake db:migrate

或者

对于 Memcache 会话：

config.action_controller.session_store = :mem_cache_store

您还需要设置一个内存缓存服务器并将其配置如下

config.cache_store = :mem_cache_store, 'localhost', '127.0.0.1:11211',
{:namespace => 'myapp123'}

您收到此错误是因为您的会话已超过 4kb 的限制。

尝试这个

在您的数据库中创建表会话。

rake db:sessions:create
rake db:migrate

在 config/initializers/session_store.rb 注释行

Application.config.session_store :cookie_store

并添加

Application.config.session_store :active_record_store
