Ruby on rails 在Rails 3.0.3中使用Net:：HTTP会导致超时：：错误

我正在试验Rails 3.0.3中的Net:：HTTP，但由于超时：：错误，无法使其工作

我有两个控制器：控制器A由控制器B调用

控制器A（xml\u provider\u Controller.rb）：

有一次我叫“http://0.0.0.0:3000/mains/search“，我得到一个超时：：错误

日志上写着：

正在打开与本地主机的连接。。。
开的
您是否在“当前应用程序”中过账？如果是，您可能需要确保至少有两个后端进程处理请求，否则这一个方法将自身锁定。如果您有两个后端进程处理请求，那么您最好希望它们不是同时发出相同的请求；）诸如此类。
对于其他任何有NET:：HTTP超时问题的人，例如，在同一应用程序中运行API并通过HTTP连接到它时，假设Unicorn是所选的服务器（我确信类似的方法也适用于其他服务器），将以下内容添加到
config/Unicorn.rb
：

worker_processes 2

当然，您可以有>2个进程，但2是最小值

match 'xmlprovider/availabilityByDateRequest' => 'xml_provider#availabilityByDateRequest', :via => :post, :format => 'xml'
