我的rails应用程序因为ActionView::MissingTemplate-exception而引发异常.这是因为请求具有ACCEPT带有值的http标头: */*.该应用无法找到此格式的模板(这是我期望发生的).用户代理已设置为Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.116 Safari/537.36.

关于这意味着什么,我很好奇(并且有点担心).这是rails的问题,我的应用程序的问题,还是攻击媒介？我已经看到类似问题的答案(例如Ruby on Rails和来自PSP的奇怪的HTTP_ACCEPT标题),它建议拯救这些异常并回答格式设置为HTML.但是,在使用这种方法之前,我现在想,如果: */*是可接受的值ACCEPT,以及哪个浏览器会设置它.

我在Rails 3.2.13上.

我偶然发现了rails源代码中的这段代码:

# File actionpack/lib/action_view/helpers/output_safety_helper.rb, line 30
def safe_join(array, sep=$,)
  sep ||= "".html_safe
  sep = ERB::Util.html_escape(sep)

  array.map { |i| ERB::Util.html_escape(i) }.join(sep).html_safe
end

怎么$,办？我阅读了Regexp文档,但我找不到任何相关内容.

我正在使用Magento(1.6.2.0)XMLRPC-API来分配/删除某个类别的产品.我最近查看了异常日志,发现有很多异常.每当我更新类别时,都会发生以下错误:
