Mongrel Rails 错误：RoutingError（没有与 {:method=>:get} 匹配的路由“/://0”）：答案

【问题标题】：Mongrel Rails error: RoutingError (No route matches "/://0" with {:method=>:get}):Mongrel Rails 错误：RoutingError（没有与 {:method=>:get} 匹配的路由“/://0”）：
【发布时间】：2010-10-16 23:32:14
【问题描述】：

我一直在我的 Rails 生产日志中看到这个错误，有什么问题吗？我在 apache 上使用 mongrel 集群运行 rails。 RoutingError (没有路由匹配 "/://0" 与 {:method=>:get}):

不确定是什么尝试的 url 导致了错误。

编辑：这是我的 routes.rb 文件

ActionController::Routing::Routes.draw 做 |map|

map.signout '/account/signout', :controller => 'sessions', :action => 'destroy'
map.signin '/account/signin', :controller => 'sessions', :action => 'new'
map.signup '/account/signup', :controller => 'users', :action => 'new'

map.change_password '/account/change_password', :controller => 'users', :action => 'change_password'
map.forgot_password '/account/forgot_password', :controller => 'users', :action => 'forgot_password'
map.reset_password '/account/reset_password/:id', :controller => 'users', :action => 'reset_password'   

map.preferences '/preferences', :controller => 'preferences', :action => 'index'
map.dashboard '/dashboard', :controller => 'dashboard', :action => 'index'
map.account '/account', :controller => 'account', :action => 'index'
map.affiliate '/affiliates', :controller => 'affiliates', :action => 'index'

map.essentials '/preferences/essentials', :controller => 'preferences/essentials', :action => 'index'
map.contacts '/preferences/contacts', :controller => 'preferences/contacts', :action => 'index'
map.travel '/preferences/travel', :controller => 'preferences/travel', :action => 'index'
map.online '/preferences/online', :controller => 'preferences/online', :action => 'index'
map.reminders '/preferences/reminders', :controller => 'preferences/reminders', :action => 'index'
map.miscellaneous '/preferences/miscellaneous', :controller => 'preferences/miscellaneous', :action => 'index'

map.home '/home', :controller => 'main', :action => 'home'
map.about '/about', :controller => 'main', :action => 'about'
map.gift '/gift', :controller => 'gift', :action => 'index'
map.plans '/plans', :controller => 'main', :action => 'plans'
map.faqs '/faqs', :controller => 'main', :action => 'faqs'
map.contact '/contact', :controller => 'main', :action => 'contact'

map.tos '/terms_of_service', :controller => 'main', :action => 'terms_of_service'
map.privacy '/privacy', :controller => 'main', :action => 'privacy'

map.root :controller => 'main'

map.connect ':controller/:action/:id'
map.connect ':controller/:action/:id.:format'

结束

谢谢！

【问题讨论】：

需要更多信息，例如您是如何收到该错误的。那将是一个好的开始。
人们似乎忽略了对 /account/://0 的实际请求正在发生的事实。检查 apache 日志文件，看看是否有这些请求的引用者。

【解决方案1】：

呃 - 问题似乎是有人请求"/account/://0" 的 URL？为什么不会产生路由错误？我不希望这会击中您定义的任何路线。

【解决方案2】：

这可能只是一次黑客攻击吗？

【讨论】：

【解决方案3】：

您的 config/routes.rb 文件中似乎存在问题。

如果您可以将 routes.rb 文件的内容和您尝试加载的 URL 添加到您的消息中，我们可以提供进一步的帮助。

【解决方案4】：

map.connect ':controller/:action/:id' map.connect ':controller/:action/:id.:format'

按照下面给出的顺序交换这些语句。

map.connect ':controller/:action/:id.:format' map.connect ':controller/:action/:id'

在 routes.rb 中没有提供 restful 路由，因此问题可能不在于方法定义或调用任何成员方法。

格式只是覆盖了 url 源。
