无法弄清楚这个错误意味着什么（rails Net :: OpenTimeout：执行已过期）

我的rails应用程序出错了：Net :: OpenTimeout：执行过期了

我研究了这个错误，并且每个人都将它与Mailer联系起来，我认为这与我无关。 这是错误堆栈跟踪：

它发生在我通过twilio发送短信时，只发生过一次。 在此之前，我发送了6k短信，没有任何问题。 这不是问题吗？ 会造成什么？

Answer 1

无法弄清楚这个错误意味着Net :: OpenTimeout：执行过期了

这只是一个超时错误。 它发生在第三方服务器需要时间响应时。

解

1. 后台作业中的第一个移动方法。
2. 在下一个请求中添加一些延迟。 延迟取决于您每秒向第三方服务器拨打电话的能力或限制。 sleep 5在大多数情况下都有效。
3. 如果可能，请发出batch请求。

参考

1. 每秒出站呼叫和短信的限制是什么？
2. 使用Twilio SMS API，我可以在一个post中指定多个目标手机吗？
3. 如何使用twilio API发送批量短信

Answer 2

SMS服务url没有收到任何回复。 由于没有响应而请求处理失败，并且已超过请求的等待时间。 连接问题与服务，所以你经历了超时

Answer 3

我在我的API中使用此短信服务在手机上发送消息，之前遇到过此错误。 这是服务器的连接问题。 应用程序正在向服务URL发送请求，并且它已经等待了一段时间，当没有收到响应且等待时间已超过时，由于超时而导致请求执行停止并且rails发出此错误。
