圣杯:无法通过pynamodb连接到DynamoDB

Question

它在我配置了.aws的本地机器上工作得很好。但是，lambda无法通过自动生成的iam角色与dynamodb表连接。我甚至尝试通过IAM控制台向角色显式添加策略：

{
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": "dynamodb:*",
            "Resource": "arn:aws:dynamodb:ap-south-1:*:table/*"
}

但是仍然得到这个错误(调试日志)：

An error occurred (AccessDeniedException) on request (SQ60ECK3UMM6LLEBC2K04S6HE7VV4KQNSO5AEMVJF66Q9ASUAAJG) on table (lmk_staging_posts) when calling the DescribeTable operation:

Answer 1

您必须将策略添加到config.json中，并将所有策略放入"autogen_policy":false -dev.json中，例如：

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "logs:CreateLogGroup",
        "logs:CreateLogStream",
        "logs:PutLogEvents",
        "s3:*",
        "dynamodb:*"
      ],
      "Resource": "*"
    }
  ]
}

通过这种方式，您可以手动设置策略。
