Question

所有

我的一切工作正常：图片正在上传，可以通过Web使用回形针和S3进行访问，除非我登录rails c并输入类似的内容：

> User.first.avatar.exists?
[AWS S3 400 0.093287 0 retries] head_object(:bucket_name=>"mozg-staging-static",:key=>"users/avatars/000/000/001/original/289736.jpg") AWS::S3::Errors::BadRequest AWS::S3::Errors::BadRequest

=> false

clear方法也是如此。找不到解决方案。

我有此权限政策：

    {
            "Sid": "Stmt1436958517000",
            "Effect": "Allow",
            "Action": [
                "s3:AbortMultipartUpload",
                "s3:DeleteObject",
                "s3:DeleteObjectVersion",
                "s3:GetBucketAcl",
                "s3:GetBucketCORS",
                "s3:GetObject",
                "s3:GetObjectAcl",
                "s3:GetObjectVersion",
                "s3:GetObjectVersionAcl",
                "s3:ListBucket",
                "s3:ListBucketMultipartUploads",
                "s3:ListBucketVersions",
                "s3:ListMultipartUploadParts",
                "s3:ListObjects",
                "s3:PutObject",
                "s3:PutObjectAcl",
                "s3:PutObjectVersionAcl",
                "s3:RestoreObject"
            ],
            "Resource": [
                "arn:aws:s3:::mozg-staging-static",
                "arn:aws:s3:::mozg-staging-static/*"
            ]
        }

感谢您的支持。

这可能是您的政策的问题，您可以尝试：

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
          "s3:ListBucket"
      ],
      "Resource": ["arn:aws:s3:::mozg-staging-static"]
    },
    {
      "Effect": "Allow",
      "Action": [
        "s3:PutObject",
        "s3:GetObject",
        "s3:DeleteObject"
      ],
      "Resource": ["arn:aws:s3:::mozg-staging-static/*"]
    }
  ]
}

需要在存储桶级别设置ListBucket操作，而需要针对存储桶中的对象设置PutObject，GetObject和DeleteObject。我遗漏了其他行动以保持答案简短。如果需要，您当然需要重新添加它们。您可以在此处找到操作列表以及它们是桶操作还是对象操作：http://docs.aws.amazon.com/AmazonS3/latest/dev/using-with-s3-actions.html

Rails回形针错误`AWS :: S3 :: Errors :: BadRequest`对`exists？`和`clear`
