对资源的访问https://sqs.us-east-1.amazonaws.com/被拒绝

Question

有很多人提到这个错误，但是，

下面是为lambda（AWS:：Serverless:：Function）创建的执行角色：

{
  "permissionsBoundary": {
    "permissionsBoundaryArn": "arn:aws:iam::111222333444:policy/some-permission-boundary",
    "permissionsBoundaryType": "Policy"
  },
  "roleName": “some-role-WebhookSampleFunctionRol-6Z7GFHJYHO0T",
  "policies": [
    {
      "document": {
        "Version": "2012-10-17",
        "Statement": [
          {
            "Effect": "Allow",
            "Action": [
              "logs:CreateLogGroup",
              "logs:CreateLogStream",
              "logs:PutLogEvents"
            ],
            "Resource": "*"
          }
        ]
      },
      "name": "AWSLambdaBasicExecutionRole",
      "id": "ANDDDDDC42545SKXIK",
      "type": "managed",
      "arn": "arn:aws:iam::aws:policy/service-role/AWSLambdaBasicExecutionRole"
    }
  ],
  "trustedEntities": [
    "lambda.amazonaws.com"
  ]
}

其中某些权限边界是

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "logs:CreateLogGroup",
                "logs:CreateLogStream",
                "logs:PutLogEvents"
            ],
            "Resource": [
                "arn:aws:logs:us-east-1:111222333444:log-group:*"
            ],
            "Effect": "Allow",
        },
        {
            "Action": [
                "sqs:*"
            ],
            "Resource": [
                "arn:aws:sqs:us-east-1:*:*"
            ],
            "Effect": "Allow",
        }
    ]
}

Lambda执行以下操作：

async function sendToQueue(message) {
  const params = {
    MessageBody: JSON.stringify(message),
    QueueUrl: process.env.queueUrl
  };
  return new Promise((resolve, reject) =>
    sqs.sendMessage(params, (error, data) => error ? reject(error) : resolve())
  );
}

这就产生了错误：

"errorMessage": "Access to the resource https://sqs.us-east-1.amazonaws.com/ is denied.",
    "errorType": "AccessDenied",

我们为sqs:某些权限边界中跨帐户的任何队列提供了actions:

为什么lambda无法将消息发送到队列？




Answer 1

我也有同样的问题，但是无服务器FW。在控制台抛出此错误：

`API: sqs:CreateQueue Access to the resource https://sqs.eu-west-1.amazonaws.com/ is denied.`

我从无服务器代理在自定义角色中添加权限。我使用此代理的权限（我希望有人能帮助您）

此权限（没有sqs*），建议从无服务器FW文档

Answer 2

权限边界是使用托管策略设置基于标识的策略可授予IAM实体的最大权限的高级功能。

实体的权限边界允许它只执行其基于标识的策略和权限边界允许的操作。

资料来源：https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_boundaries.html

您确实在权限边界中包含sqs:*但在lambda执行角色的策略中未包含任何与sqs相关的操作。

您应该将具有sqs权限的策略附加到lambda执行角色：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "sqs:*"
            ],
            "Resource": [
                "arn:aws:sqs:us-east-1:*:*"
            ],
            "Effect": "Allow",
        }
    ]
}
