我试图让Django的静态文件上传到S3，但istead我得到一个403 Forbidden错误，我不知道为什么。

完整堆栈跟踪：

谷歌搜索此异常不转了什么有趣的事。 我怀疑我误配置的东西，虽然我不知道。 可能有人点我在正确的方向？ 感谢您的时间和考虑。

Answer 1:

我使用的是亚马逊IAM的特定密钥ID和访问密钥，只是碰到了禁止同403 ...原来你需要给同时定位桶根及其子对象的权限： 

{
  "Statement": [
    {
      "Principal": {
          "AWS": "*"
      },
      "Effect": "Allow",
      "Action": "s3:*",
      "Resource": ["arn:aws:s3:::bucket-name/*", "arn:aws:s3:::bucket-name"]
    }
  ]
}


Answer 2:

我会建议您尝试单独测试你的AWS证书来验证证书是否的确需要权限读取和写入数据到S3桶。 下面应该工作： 

>>> import boto
>>> s3 = boto.connect_s3('<access_key>', '<secret_key>')
>>> bucket = s3.lookup('donebox-static')
>>> key = bucket.new_key('testkey')
>>> key.set_contents_from_string('This is a test')
>>> key.exists()
>>> key.delete()

你应该尝试与其他桶（“donebox媒体”）同样的测试。 如果一切正常，权限是正确的，问题就出在Django的储存代码或配置。 如果失败了403，那么：

  • 该access_key / SECRET_KEY字符串不正确
  • 该access_key / SECRET_KEY是正确的，但该帐户没有必要的权限来写入桶

我希望帮助。 请汇报你的发现。



Answer 3:

我有同样的问题，最后发现真正的问题是服务器时间。 这是错误配置和AWS与不允许的403响应。

使用Debian，你可以使用自动配置NTP：

用ntpdate 0.pool.ntp.org



Answer 4:

这也将是您的机器的时间设置不正确



Answer 5:

这也有可能是正在使用错误的凭据。 核实： 

import boto
s3 = boto.connect_s3('<your access key>', '<your secret key>')
bucket = s3.get_bucket('<your bucket>') # does this work?
s3 = boto.connect_s3()
s3.aws_access_key_id  # is the same key being used by default?

如果没有，看看~/.boto ， ~/.aws/config和~/.aws/credentials 。



Answer 6:

在这种情况下，任何人帮助，我不得不添加以下配置条目collectstatic工作，而不是返回403： 

AWS_DEFAULT_ACL = ''


Answer 7:

这里是最低权限的细化。 在所有情况下，所讨论的其他地方 s3:ListAllMyBuckets有必要对所有的桶。

在它的默认配置Django的存储器将文件上传到S3与公共读取权限-见Django的储存Amazon S3的后端

试验和错误显示，在此默认配置所需的只有两个权限是s3:PutObject在首位，并上传文件s3:PutObjectAcl到该对象的权限设置为公开。

没有额外的行动，因为从该点向前读是公开的对象总是需要的。

IAM用户策略-大众阅读的（默认）： 

{
   "Version": "2012-10-17",
   "Statement": [
       {
           "Effect": "Allow",
           "Action": "s3:ListAllMyBuckets",
           "Resource": "arn:aws:s3:::*"
       },
       {
           "Effect": "Allow",
           "Action": [
               "s3:PutObject",
               "s3:PutObjectAcl"
           ],
           "Resource": "arn:aws:s3:::bucketname/*"
       }
   ]
}

它并不总是希望有对象公开可读。 这是通过设置在设置文件中的相关属性来实现的。

Django的settings.py： 

...
AWS_DEFAULT_ACL = "private"
...

然后s3:PutObjectAcl不再需要和最小权限如下：

IAM用户策略-私募： 

{
   "Version": "2012-10-17",
   "Statement": [
       {
           "Effect": "Allow",
           "Action": "s3:ListAllMyBuckets",
           "Resource": "arn:aws:s3:::*"
       },
       {
           "Effect": "Allow",
           "Action": [
               "s3:PutObject",
               "s3:GetObject"
           ],
           "Resource": "arn:aws:s3:::bucketname/*"
       }
   ]
}


Answer 8:

另一种解决方案避免了自定义策略，并使用AWS预定义的策略：

  • 添加S3完全访问权限的用户S3。

    • IAM / 用户 / 权限和附加政策
    • 添加策略“AmazonS3FullAccess”


Answer 9:

也许你居然没有获得你想要查找/获取/创建桶..

记住： 桶名称必须在整个S3生态系统独特 ，因此，如果您尝试访问（查找/获取/创建）一个名为“测试”斗，你将有没有打开。
