Question

我有一个轨道项目和两个机械装置。一个运行Ubuntu 10.04，另一个运行12.04 beta。我在10.04机器上使用'fb_graph'宝石一切正常，但是当我在12.04机器上做的事情就像

me = FbGraph :: User.me（token）.fetch

我得到了

我不知道为什么会这样，也不知道如何解决。有任何想法吗？谢谢！

Answer 1

可能发生的原因是机器的硬件性能和网络性能。

再试几次。有时网络需要时间来加载路由信息，但是一旦加载它就会在下一次加快。这可能不是一个好的生产解决方案，但它可以诊断问题是否使网络路由更加清晰。

这可能是一个真正的网络性能问题。如果您无法调整网络，那可能对您没有帮助。

如果重试有帮助，您可以在代码周围进行重试循环。

(0..2).each do
  begin
    ... #your code goes here
    break
  rescue HTTPClient::ConnectTimeoutError
  end
end

Answer 2

HTTP请求在服务器和FB之间超时。有关如何配置HTTP客户端超时选项的说明，请参阅此github issue。

使用'fb_graph'gem时的HTTPClient :: ConnectTimeoutError
