500内部服务器错误-AWS :: S3 ::错误:: AccessDenied -CarrierWave

Question

我正在尝试通过载波上传图像，但请继续遇到500个内部服务器错误-AWS :: S3 :: errors :: consectDenied。我正在使用Ruby Gem CarrierWave配置AWS和DOTENV-rails来调用并将我的凭据隐藏在.env文件中。看来我的代码正常工作，但我被拒绝允许我的水桶。这是我第一次试图将AWS集成到一个项目中，因此我的配置可能会在此目的下方。任何帮助将不胜感激。

我已经尝试重置访问键并确保正确设置了我的区域。我什至更改了该地区，并收到了一个错误，促使我将其更改回正确的区域：" US-West-1"。我确保Dotenv-rails可以通过Rails Console获取我的凭据来正常工作。我还使用"串行"来在我的投资组合控制器中的更新操作中设置一个断点，以自己手动输入更新代码。我可以看到我正在尝试更新投资组合项目的新图像，但它总是回滚。

我希望这能起作用并能够访问AWS资源，但是也许我需要设置一些配置？到目前为止，AWS文档很难消化。我可以用帮助，谢谢。

Answer 1

修复：必须进入AWS仪表板，然后更改我要访问的S3存储桶的公共访问设置。您可以通过访问AWS仪表板，选择S3资源，选择要访问访问权限然后进入其属性菜单的存储桶来导航到它。我只是将所有内容都设置为错误。可以在此处对各个设置使用更多澄清。

管理公共访问控制列表（ACLS）

阻止新的公共ACL并上传公共对象：

false

删除通过公共ACL授予的公共访问：

false

管理公共存储桶策略

阻止新的公共存储桶政策：

false

如果存储桶有公共政策，则阻止公共和交叉计数访问：

false
