驗證碼圖像不適用於我的製作環境但開發良好

Question

我在本地機器(OSX 10.6.6,Rails3.0.1,WEBrick)中編寫了導軌應用程序。簡單驗證碼正常工作。當我將應用程序推送到我的網絡服務器(Centos5.5,Rails 3.0.1,Phusion Passenger version 3.0.2)時，沒有發現錯誤，但圖像不顯示在站點中。

我注意到/tmp有一些文件，如simple_captcha20110324-19769-1bf4hah.jpg。我在我的服務器中打開它，圖像是驗證碼圖像。所以我認爲驗證碼生成工作正常，但在生產環境中出現了問題。我跟蹤過程，發現ioctl(27, SNDCTL_TMR_TIMEBASE or TCGETS, 0x7fffc3fad550) = -1 ENOTTY (Inappropriate ioctl for device)。你有什麼建議嗎？

UPDATE：

我覺得有些錯誤在https://github.com/galetahub/simple-captcha可能。我選擇了這個分支https://github.com/kares/simple_captcha所有的env工作正常！

Answer 1

您應該嘗試在config/environments/production.rb文件中設置config.serve_static_assets = true。

默認情況下，出於性能方面的原因，rails在生產模式下不提供靜態內容。你的網絡服務器應該被配置來做到這一點。

Answer 2

如果我記得captcha在開發和生產環境中有不同的密鑰，您是否已經檢查過它？

Answer 3

https://github.com/galetahub/simple-captcha使用send_file（來自rails streaming api）來傳輸驗證碼圖像。你在你的apache配置中啓用了mod-xsendfile嗎？
