IoT - AMQJS0008I套接字关闭- AUTHORIZATION_FAILURE

Question

我正在尝试将AWS IoT配置为与AWS放大器一起使用。我总是看到错误的"AMQJS0008I套接字关闭了.“和CloudWatch说”，这是我配置的

1. I AM策略用于认证的认知身份池

    {
        "Version": "2012-10-17",
        "Statement": [
            {
                "Sid": "VisualEditor0",
                "Effect": "Allow",
                "Action": [
                    "cognito-identity:*",
                    "mobileanalytics:PutEvents",
                    "cognito-sync:*",
                    "iot:Connect",
                    "iot:Publish",
                    "iot:Subscribe",
                    "iot:Receive",
                    "iot:GetThingShadow",
                    "iot:UpdateThingShadow",
                    "iot:DeleteThingShadow",
                    "iot:AttachPolicy",
                    "iot:AttachPrincipalPolicy"
                ],
                "Resource": "*"
            }
        ]
    }

1. IoT的认知识别策略

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "iot:Connect",
      "Resource": "arn:aws:iot:ap-south-1:XXXXXXX:client/${iot:ClientId}"
    },
    {
      "Effect": "Allow",
      "Action": [
        "iot:Publish",
        "iot:Subscribe",
        "iot:Receive"
      ],
      "Resource": "arn:aws:iot:ap-south-1:XXXXXXX:topic/*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "iot:UpdateThingShadow",
        "iot:GetThingShadow",
        "iot:DeleteThingShadow"
      ],
      "Resource": "arn:aws:iot:ap-south-1:XXXXXXX:thing/*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "iot:AttachPrincipalPolicy”,
        "iot:AttachPolicy"
      ],
      "Resource": [
        "*"
      ]
    }
  ]
}

1. 使用AWS CLI

附加个人认知

aws iot attach-policy --policy-name "hub-iot-policy" --target "ap-south-1:XXXX-USER_COGNITO_IDENTITY

使用

1. 连接和订阅使用

软件包的AWS扩增

    “@aws-amplify/api": "^3.1.7",
    "@aws-amplify/auth": "^3.2.4",
    "@aws-amplify/core": "^3.2.4",
    "@aws-amplify/pubsub": "^3.0.8”,

代码是

PubSub.addPluggable(new AWSIoTProvider({
      aws_pubsub_region: config.pubsub.REGION,
      aws_pubsub_endpoint: `wss://${config.pubsub.MQTT_ID}.iot.${config.pubsub.REGION}.amazonaws.com/mqtt`,
    }));
PubSub.subscribe('hub31-iot-thing').subscribe({
      next: data => console.log('Message received', data),
      error: error => console.error(error),
      close: () => console.log('Done'),
    });
  }

1. JS控制台以

抛出错误

{provider: AWSIoTProvider，error：{…}}错误：{invocationContext:未定义，errorCode: 8，errorMessage："AMQJS0008I Socket .“}提供程序: AWSIoTProvider {_config：{…}，_clientsQueue: ClientsQueue，_topicObservers: Map(1)，_clientIdObservers: Map(1)}

AUTHORIZATION_FAILURE

1. 云表显示错误

{
    "timestamp": "2020-04-21 00:13:24.953",
    "logLevel": "ERROR",
    "traceId": “308de5a7-XXXX-d2d5-XXXX-7e24b6d6e0e6",
    "accountId": “XXXXXXXX",
    "status": "Failure",
    "eventType": "Connect",
    "protocol": "MQTT",
    "clientId": “f5e1abef-XXXX-44af-XXXX-4a327b45481c",
    "principalId": “XXXXX:CognitoIdentityCredentials",
    "sourceIp": “XXXX",
    "sourcePort": 59101,
    "reason": "AUTHORIZATION_FAILURE",
    "details": "Authorization Failure"
}

Answer 1

同样的错误，我就是这样解决的。

1.作为的认知政策

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "iot:Receive",
                "cognito-identity:*",
                "iot:Subscribe",
                "iot:AttachPolicy",
                "iot:AttachPrincipalPolicy",
                "iot:Connect",
                "mobileanalytics:PutEvents",
                "iot:GetThingShadow",
                "iot:DeleteThingShadow",
                "iot:UpdateThingShadow",
                "iot:Publish",
                "cognito-sync:*"
            ],
            "Resource": "*"
        }
    ]
}

还请注意，AttachPrincipalPolicy是不推荐的，但是为了更安全起见，我将它包括在内。

2. IoT策略作为

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "iot:*",
      "Resource": "*"
    }
  ]
}

3.通过lambda或AWS将IoT策略附加到单个认知标识。

aws iot attach-policy --policy-name "iot-policy" --target "ap-south-1:XXXX-USER-COGNITO-IDENTITY”

再次注意，不建议使用AttachPrincipalPolicy，请使用AttachPolicy

使用lambda：

export const main = async (event, context, callback) => {
    const principal = event.requestContext.identity.cognitoIdentityId;
    const policyName = 'iot-policy';

    const iot = new AWS.Iot();
    await iot.attachPrincipalPolicy({ principal, policyName }).promise();
    callback(null, "success");
};

4.测试，如果您的前端配置正确，您应该能够解决errorCode: 8，errorMessage: AMQJS0008I套接字关闭错误。

5.微调现在微调物联网策略，根据您的要求，并立即检查更改是否有效
