Amazon S3签名URL和Cloudfront-访问被拒绝 [英] Amazon S3 Signed URL and Cloudfront - Access Denied

问题描述

我正在使用以下方法创建一个签名的URL ：

I am creating a signed url using the following:

AWS_ACCESS_KEY_ID = my_access_key
    AWS_SECRET_ACCESS_KEY = my_secret_access_key
    KEYPAIR_ID = my_keypair_id
    KEYPAIR_FILE = path_to_keypair_file
    CF_DISTRIBUTION_ID = cf_dist_id
    my_connection = cloudfront.CloudFrontConnection(
        AWS_ACCESS_KEY_ID,
        AWS_SECRET_ACCESS_KEY
    )


    distro_summary = my_connection.get_all_distributions()[0]
    distro_info = my_connection.get_distribution_info(distro_summary.id)
    distro = distro_summary.get_distribution()    

    SECS = 8000
    signed_url = distro.create_signed_url(
                    "https://%s/%s" % (distro_info.domain_name, 'restaurant_1_banner.png'),
                    KEYPAIR_ID,
                    expire_time=time.time() + SECS,
                    valid_after_time=None,
                    ip_address=None,
                    policy_url=None,
                    private_key_file=KEYPAIR_FILE
                    #private_key_string=KEYPAIR_ID
                    )


    return signed_url   

这将返回一个网址，例如： https://d1yllqv1oc7n6x.cloudfront.net /restaurant_1_banner.png?Expires=1426681326.67&Signature=Nsvyl-EowDRGuw-MfdgS34C6bsHKKC2L88ROfPBRAnsbpoeYfpJj6NQaTj4PGiG02Z7PRqkk5F0cBWKOik738H8MrlQfou4n FLx94fSMo8vwFDg9jKLTMB1T0AGjWvgAcDlkLo4nYxyHQ077pwp3Do8g1eP62QD-〜Ys4kejtVGtPTx6O1pM4gRLsmM8Kn7HJ618Hp4XMgRWwqJaCL-2C0YQP1PdEMbSOS6ZrmGTN〜U5T-S-PZX1poS6qRiY4-Ma66DVLgmOTBh5vqjCWEqsbKZKFWFufsA2mMa4ON11yBUSyIbGJPpgKdRLU0pZuo7RX3〜sIe6Q9w __&安培;密钥对-ID = APKAISF4B35DSGOUTGTQ

This returns a url like: "https://d1yllqv1oc7n6x.cloudfront.net/restaurant_1_banner.png?Expires=1426681326.67&Signature=Nsvyl-EowDRGuw-MfdgS34C6bsHKKC2L88ROfPBRAnsbpoeYfpJj6NQaTj4PGiG02Z7PRqkk5F0cBWKOik738H8xrlQQf8CuS0AouisnqMvZ4FLx94fSMo8vwFDg9jKLTMB1T0AGjWvgAcDlkLo4nYxyHQ077pwp3Do8g1eP62QD-~Ys4kejtVGtPTx6O1pM4gRLsmM8Kn7HJ618Hp4XMgRWwqJaCL-2C0YQP1PdEMbSOS6ZrmGTN~U5T-s-PZX1poS6qRiY4-Ma66DVLgmOTBh5vqjCWEqsbKZKFWFufsA2mMa4ON11yBUSyIbGJPpgKdRLU0pZuo7RX3~sIe6Q9w__&Key-Pair-Id=APKAISF4B35DSGOUTGTQ"

当我点击此链接，我收到消息：

When I click on this link, I get the message:

<Error>
    <Code>AccessDenied</Code>
    <Message>Access denied</Message>
</Error>

这是我的桶策略 code> s3 存储桶。

This is my bucket policy for my s3 bucket.

{
"Version": "2008-10-17",
"Id": "PolicyForCloudFrontPrivateContent",
"Statement": [
    {
        "Sid": "1",
        "Effect": "Allow",
        "Principal": {
            "AWS": "arn:aws:iam::cloudfront:user/CloudFront Origin Access Identity E3I8A03QRR3ASO"
        },
        "Action": "s3:GetObject",
        "Resource": "arn:aws:s3:::menumaster/*"
    }
]
}

请让我知道是否需要其他信息。

Please let me know if any additional information is required.

推荐答案

这是我的存储桶策略。

This is my bucket policy.

    {
        "Version": "2008-10-17",
        "Id": "PolicyForCloudFrontPrivateContent",
        "Statement": [
            {
                "Sid": "1",
                "Effect": "Allow",
                "Principal": {
                    "AWS": "arn:aws:iam::cloudfront:user/CloudFront Origin Access Identity EH238ELEGANOC"
                },
                "Action": "s3:GetObject",
                "Resource": "arn:aws:s3:::onur.deneme/*"
            }
        ]
    }

这是分布：

This is the distribution : di53i9yykewl5.cloudfront.net

限制存储桶访问：是

原始访问身份：使用现有身份

Origin Access Identity : Use an Existing Identity

限制查看者访问（使用签名的URL）：是
受信任签名者：自我

Restrict Viewer Access(Use Signed URLs) : Yes Trusted Signers : Self

不应有其他ACL或策略。

There should be no other ACL or policy.
