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

Question

我是 ruby​​ 和 rails 的新手已有几个月了。我参加了 ruby​​ 和 rails 的类(class)，这使我能够创建一个餐厅博客网站。好吧，我最近开始改造网站，为我的 friend 制作。所以它只是改变一些关于图片、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才能创建和发布评论等。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，而且我的 Rails 服务器中不断出现错误。见下文!我搜索了又搜索，似乎找不到解决方案。我真正改变的唯一一件事是几张图片和一些措辞。我没有弄乱登录编码、创建登录代码等。在我继续搜索的同时，任何帮助都会很棒。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 状态代码并不表示错误。它只是意味着 Assets 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。

参见 HTTP 3xx status codes
