照片上传后的服务器超时

标签： ruby-on-rails postgresql heroku amazon-s3 carrierwave

我正在使用Postgres爱好基本数据库进行Heroku的爱好计划。当我使用导入到Amazon S3的载波gem上传图像时，服务器超时。上传将会发生，但它需要一段时间才能处理。如果我上传一张或四张照片，也会出现同样的问题。

有人知道我可以做些什么来解决这个问题吗？创建照片时，由于我在整个应用程序中使用不同形状的照片，因此创建了8个不同大小的版本。

我在下面列出了日志。

答案 0 :(得分：2)

是的，请参阅heroku/router日志，表明请求的时间超过30秒。 Heroku要求你在30秒内返回 - see this article解释一切。

我建议直接上传S3（可能是like this），然后使用后台工作程序进行下载/处理/上传。然后，您不必毫无必要地捆绑网络连接，并且您将拥有更加可扩展的解决方案。
