decode_www_form_component抱怨＆＃34;无效％-encoding＆＃34;在Rails Refinery App中

时间：2015-01-16 03:42:45

标签： ruby-on-rails refinerycms

TLDR;在某些不太可能的情况下（与á和＆amp;等字符相关），炼油厂缓存（tmp/cache/）变得腐败，导致页面无法更新。

我还没有为此找到长期解决方案但是现在设法修复它（请参阅下面的修复部分）。我发布了我发现的东西，因为谷歌搜索没有提供任何相关的内容。

通过炼油厂的管理界面更新页面失败，出现此错误：

要点：

  • 更新称为
  • refinery-hooks在更新后清理缓存
  • 此
    • 处理的文件名错误
  • rails在文件名
    • 上调用URI.decode_www_form_component
  • 爆炸性的神奇乐趣！

注意：

  • 这适用于炼油厂的2.1.0版本，我没有机会在新版本中测试它。
  • 相关文件位于：tmp/cache/BA1/EDA/http%3A%2F%2Fwhakarauora.org.nz%2Fsystem%2Fresources%2FW1siZiIsIjIwMTQvMTAvMDYvMTdfMDVfNTBfNzkzX2RlX0JyZXNfMjAwOF9QbGFubmluZ19mb3JfVG9sZXJhYmlsaXR5X1Byb21vdGluZ19wb3NpdGl2ZV9hdHRpdHVkZXNfYW5kX2JlaGF2aW91cnNfdG93YXJkc190aGVfTV9vcml/fbGFuZ3VhZ2VfYW1vbmdfbm9uX01fb3JpX05ld19hbm5vdGF0ZWQucGRmIl1d%2Fde%2520Bres%2520-%25202008%2520-%2520Planning%2520for%2520Tolerability%2520Promoting%2520positive%2520attitudes%2520and%2520behaviours%2520towards%2520the%2520M%25c4%/2581ori%2520language%2520among%2520non-M%25c4%2581ori%2520New-annotated.pdf%3F
  • 这似乎是http请求的记录
  • 这些文件已预先存在（不是由更新调用创建）
  • 问题似乎是
    • 进行了百分比编码调用（% - ＆gt; %25）
    • 将巨大的文件名写入目录...the%2520M%25c4%/
    • 这分为百分比编码的三个字符（在这种情况下为%25）
    • 导致URI.decode_www_form_component（URI.unescape无效）
      • 出现问题
  • 这意味着你的缓存文件中有很多非ASCII或标点符号 - 非英语说 - 增加你发生这种角落案件的可能性。

修正：

我通过sshing到框中修复此问题，找到有find RAILS_DIRNAME/tmp/cache -name '*%' -or -name '*%?'的违规dirs，然后删除它们。这解决了现在的问题，但可能需要稍后重复。

2 个答案:

答案 0 :(得分：0)

我找到了解决这个问题的方法。也许它不是很漂亮，但它对我有用。在environments / production.rb中将config.action_controller.perform_caching更改为 false

答案 1 :(得分：0)

在运行rake tmp:cache:clear

之后，将文件名更改为短名称并使用下划线代替空格
