它发生在我通过twilio发送短信时，只发生过一次。在此之前，我已经发送了6k条短信，没有任何问题。这不是问题吗？是什么原因造成的？

Answer 1

无法弄清楚这个错误意味着什么Net:：OpenTimeout:执行已过期

这只是一个超时错误。当第三方服务器需要时间进行响应时，就会发生这种情况。

解决方案

1. 后台作业中的第一个移动方法
2. 在提出下一个请求时增加一些延迟。延迟取决于每秒对第三方服务器的呼叫能力或限制。sleep 5在大多数情况下是有效的
3. 如果可能，请发出batch请求

1. 每秒呼出电话和短信息的限制是什么
2. 使用Twilio SMS API，我可以在一篇文章中指定多个目的地电话吗
3. 如何使用twilio API发送批量短信

Answer 2

没有收到来自SMS服务url的响应。由于没有响应，请求处理失败，并且已超过请求的等待时间。服务的连接问题，因此您遇到超时

Answer 3

我在API中使用过此SMS服务在手机上发送消息，以前也遇到过此错误。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定的时间，当没有收到响应并且超过等待时间时，请求执行由于超时而停止，rails给出了此错误。
