我在 heroku 上的 rails 应用程序允许用户使用回形针上传要存储在亚马逊网络服务 S3 上的照片。

当照片大小超过 1.5MB 时，应用程序似乎会超时。解决此问题的最佳方法是什么？

如果有帮助，这是堆栈跟踪吗？

Heroku 对通过路由器网格到您的测功机的所有请求处理有 30 秒的超时。

看起来您的上传足够大，需要更多时间才能完成，您无法通过 Heroku 运行该大小/长度的请求。文档在这里，解释他们的政策：https ://devcenter.heroku.com/articles/request-timeout

解决此限制的一种方法是创建一个允许公共写入的 Amazon S3 存储桶，您的客户可以使用 JS 或富客户端直接上传到该存储桶。

这是一个单独的问题，解释了我们如何将 JS 直接上传到 S3：Uploading Image to Amazon s3 with HTML, javascript & jQuery with Ajax Request (No PHP)
