在 Rails 3.2.3 服务器中，我收到错误 304 Not Modified (5ms)

Question

我是 ruby​​ 和 rails 的新手几个月了。我参加了 ruby​​ 和 rails 的课程，这使我能够创建一个餐厅博客网站。好吧，我最近开始改造该网站以供我的朋友使用。所以它只是改变了一些关于图片、措辞等的东西。当我完全创建另一个博客时，我注册了一个登录页面，他们需要创建一个登录页面才能创建和发表评论等。一切似乎当我为本地主机服务器运行 rails 时工作正常，但是当我为站点创建登录以确保一切正常时。它不允许我创建登录，并且我的 Rails 服务器中不断出现错误。见下文！我已经搜索和搜索，似乎无法找到解决方案。我唯一真正改变的是一些图片和一些措辞。我没有搞乱登录编码，创建登录代码等。任何帮助都会很好，同时我会继续搜索。在此之前，我遇到了内容长度错误，所以我关注了这个网站http://theresa.multimediatechnology.at/webrick-warnings-in-ruby-1-9-3/。这似乎解决了这个问题，但现在我得到了以下信息。谢谢！

Answer 1

HTTP 状态代码不表示错误。这只是意味着资产文件（图像、css、javascript）不需要再次传输，因为浏览器已经缓存了最新版本。

见HTTP 3xx status codes
