错误尝试上传图片Heroku Web应用程序与AS3（作品在生产）迈克尔·哈特尔第11章

Question

我正在做迈克尔·哈特的辅导。第11章。

我的应用程序在产品中上传图片，但在我部署它时不会上传，但是文本MicroPost确实可以工作，所以问题出在AmazonS3的某个地方

我已将S3上的权限设置为“everyone”，以便在我的bucket上上载/删除。

我已经在我的heroku帐户上设置了正确的S3键，使用rails控制台在代码中没有它们（如教程建议的）。

以下是我尝试在web应用程序上上载内容时出现的错误消息的副本：

这是我第一次真正部署web应用程序，也是第一次使用S3，但我严格遵循了每一步，并在键入后验证了我的代码是否与教程中的代码完全相同。

请让我知道，如果有任何额外的代码，我可以提供帮助解决这个问题。

非常感谢。

Answer 1

我也有同样的问题。我认为这是一个权限问题，而且您的日志似乎也在这样说。查看AWS控制台上的IAM仪表板。确保该用户是某个组的成员，并且该组具有管理员级别的权限。这个给我修好了！

祝你好运

Answer 2

我通过将初始值设定项文件名更改为carrierwave解决了问题。用rb代替载波。铷

希望这行得通。

Answer 3

我发现这个答案很有帮助。https://stackoverflow.com/a/28465489

您需要将amazons3fullaccess策略附加到用户。

设置IAM用户时，amazon演练会告诉您将策略附加到bucket本身。他们给出的示例仅包括bucket的putobject和getobject操作。但是我认为上传需要很多操作的权限。
