ActionController :: Session :: CookieStore :: CookieOverflow當發送csv/xls文件時 - rails 2.3.5

當你使用它時，我有一個頁面，上面有很多參數的大圖。ActionController :: Session :: CookieStore :: CookieOverflow當發送csv/xls文件時 - rails 2.3.5

所以我的控制器看起來是這樣的：

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.

在爲XLS認爲我創建Excel文檔

現在，當我在頁面上一個很長的URL，並呼籲無論是XLS或CSV ，我得到這個錯誤：

我不是故意存儲我的會話任何東西，它似乎像Rails是可能把URL進入會議及其太大了？有任何想法嗎？

你是否在使用類似設計的東西？在你嘗試訪問一個url但它沒有被授權的情況下，它將url存儲在一個會話中。登錄後，它會重定向您。 –

此外，你應該保持url少於2000個字符。 [什麼是URL的最大長度]（http://stackoverflow.com/questions/417142/what-is-the-maximum-length-of-a-url） –

使用清除，也許多數民衆贊成，它是好主意，我會深入研究它。同意網址。 – Joelio

看起來像是在會話中存儲長網址 - 可能清除？ - 那是造成你的問題。

您可能會考慮將會話存儲移至ActiveRecord而不是Cookie。如果您對當前的.xls處理的執行情況沒有問題，這將是一個簡單的解決方法。問題出在Cookies存儲空間有限的情況下：4 kb。

如果您決定遷移到ActiveRecord的會話存儲，這裏的步驟：

在app/config/initializers/session_store.rb文件
改變商店:active_record_store
，那麼你應該rails generate session_migration和rake db:migrate

您可能會想到另一種會話存儲：Memcache。它速度更快，在某些情況下使用更舒適。

嗨，我沒有特意在會話中存儲任何東西，所以我的問題不是專注於移動會話存儲，而是解決我的問題（弄清楚會話中存儲什麼內容以及爲什麼） – Joelio

在您當前的實現中，您正在使用長URL，這會導致將其存儲在會話存儲中。祝你好運，解決問題。 –

您收到此錯誤是因爲您的會話超出了4kb的限制。

試試這個

在數據庫中創建表的會話。

rake db:sessions:create 
rake db:migrate

在配置/初始化/ session_store.rb 註釋行

Application.config.session_store :cookie_store

並添加

Application.config.session_store :active_record_store

錯誤信息清晰表明cookie存儲大小的溢出問題。

您的會話（默認情況下在cookie中）需要移動到活動記錄存儲或Memcache存儲來解決此問題。

對於存入數據庫會話：

config.action_controller.session_store = :active_record_store

您需要創建的會話表如下

rake db:sessions:create 
rake db:migrate

對於內存緩存會話：

config.action_controller.session_store = :mem_cache_store

而且你甲腎上腺素編輯設置一個內存緩存服務器，並將其配置爲如下

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