ruby-on-rails - 如何处理XMLRPC::FaultException errors?

Question

我为每个帖子都提供了一个pingback列表。看起来像这样:

def send_trackback
  #do stuff
  begin
    Pingback::Client.new.ping(source_uri, target_uri)
    trackback.status = 1
    trackback.save
  rescue
    trackback.status = 2
    trackback.save
    nil
  end
end

这是完整的错误:

  XMLRPC::FaultException (The specified target URL cannot be used as a target. It either doesn’t exist, or it is not a pingback-enabled resource.):
  app/controllers/posts_controller.rb:67:in `block in send_trackback'
  app/controllers/posts_controller.rb:62:in `send_trackback'
  app/controllers/posts_controller.rb:8:in `pingback'

Rendered /usr/local/lib/ruby/gems/1.9.1/gems/actionpack-3.1.1/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (4.6ms)

状态开始时为0，但是如果ping操作失败，则可以，但是我希望状态设置为2，并且我希望它继续前进，不会对Rails抛出错误。如果成功，我希望状态设置为1。

开始不应该-救援块可以解决这个问题吗？我想念什么？

Answer 1

那应该工作。看起来异常是在pingback/send_trackback中触发的，而不是send_pingback中触发的
