Overview

An API client for IoTDataPlane. To construct a client, you need to configure a ‘:region` and `:credentials`.

client = Aws::IoTDataPlane::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the [developer guide](/sdk-for-ruby/v3/developer-guide/setup-config.html).

See #initialize for a full list of supported configuration options.

#initialize(options) ⇒ Client

Returns a new instance of Client.

Parameters:

  • options (Hash)

Options Hash (options):

  • :plugins (Array<Seahorse::Client::Plugin>) — default: []] —

    A list of plugins to apply to the client. Each plugin is either a class name or an instance of a plugin class.

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials. This can be an instance of any one of the following classes:

    • ‘Aws::Credentials` - Used for configuring static, non-refreshing credentials.

    • ‘Aws::SharedCredentials` - Used for loading static credentials from a shared file, such as `~/.aws/config`.

    • ‘Aws::AssumeRoleCredentials` - Used when you need to assume a role.

    • ‘Aws::AssumeRoleWebIdentityCredentials` - Used when you need to assume a role after providing credentials via the web.

    • ‘Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an access token generated from `aws login`.

    • ‘Aws::ProcessCredentials` - Used for loading credentials from a process that outputs to stdout.

    • ‘Aws::InstanceProfileCredentials` - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • ‘Aws::ECSCredentials` - Used for loading credentials from instances running in ECS.

    • ‘Aws::CognitoIdentityCredentials` - Used for loading credentials from the Cognito Identity service.

    When ‘:credentials` are not configured directly, the following locations will be searched for credentials:

    • ‘Aws.config`

    • The ‘:access_key_id`, `:secret_access_key`, `:session_token`, and `:account_id` options.

    • ENV, ENV, ENV, and ENV

    • ‘~/.aws/credentials`

    • ‘~/.aws/config`

    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of ‘Aws::InstanceProfileCredentials` or `Aws::ECSCredentials` to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV to true.

  • :region (required, String) —

    The AWS region to connect to. The configured ‘:region` is used to determine the service `:endpoint`. When not passed, a default `:region` is searched for in the following locations:

Examples:

Request syntax with placeholder values


resp = client.publish({
  topic: "Topic", # required
  qos: 1,
  retain: false,
  payload: "data",
  user_properties: "UserProperties",
  payload_format_indicator: "UNSPECIFIED_BYTES", # accepts UNSPECIFIED_BYTES, UTF8_DATA
  content_type: "ContentType",
  response_topic: "ResponseTopic",
  correlation_data: "CorrelationData",
  message_expiry: 1,
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :topic (required, String) —

    The name of the MQTT topic.

  • :qos (Integer) —

    The Quality of Service (QoS) level. The default QoS level is 0.

  • :retain (Boolean) —

    A Boolean value that determines whether to set the RETAIN flag when the message is published.

    Setting the RETAIN flag causes the message to be retained and sent to new subscribers to the topic.

    Valid values: ‘true` | `false`

    Default value: ‘false`

  • :payload (String, StringIO, File) —

    The message body. MQTT accepts text, binary, and empty (null) message payloads.

    Publishing an empty (null) payload with retain = ‘true` deletes the retained message identified by topic from Amazon Web Services IoT Core.

  • :user_properties (String) —

    A JSON string that contains an array of JSON objects. If you don’t use Amazon Web Services SDK or CLI, you must encode the JSON string to base64 format before adding it to the HTTP header. ‘userProperties` is an HTTP header value in the API.

    The following example ‘userProperties` parameter is a JSON string which represents two User Properties. Note that it needs to be base64-encoded:

    ‘[“alpha”, “45”]`

    **SDK automatically handles json encoding and base64 encoding for you when the required value (Hash, Array, etc.) is provided according to the description.**

  • :payload_format_indicator (String) —

    An ‘Enum` string value that indicates whether the payload is formatted as UTF-8. `payloadFormatIndicator` is an HTTP header value in the API.

  • :content_type (String) —
