使用API发布到Greengrass主题

Question

如何在AWS上为AWS Greengrass创建Api网关？我希望能够使用第三方应用程序通过API发布到主题

Answer 1

物联网发布可以通过物联网核心端点https://docs.aws.amazon.com/iot/latest/apireference/API_iotdata_Publish.html将消息发布到MQTT主题

您的应用程序接口可以使用AWS SDK调用Iot Publish

• AWS SDK for .NET
• AWS SDK for C++
• AWS SDK for Go
• AWS SDK for Java V2
• AWS SDK for JavaScript
• AWS SDK for PHP V3
• AWS SDK for Python
• AWS SDK for Ruby V3

调用物联网发布需要IAM权限

"Version": "2012-10-17",
"Statement": [
    {
        "Sid": "IOTAccess",
        "Effect": "Allow",
        "Action": [
            "iot:Publish"
        ],
        "Resource": [
            "arn:aws:iot:us-east-1:123456789012:topic/topicName"
        ]
    }
]
}
