Options

--channel-name (string)

The name of the channel where the messages are sent.

--messages (list)

The list of messages to be sent. Each message has the format: { "messageId": "string", "payload": "string"}.

The field names of message payloads (data) that you send to IoT Analytics:

  • Must contain only alphanumeric characters and undescores (_). No other special characters are allowed.
  • Must begin with an alphabetic character or single underscore (_).
  • Cannot contain hyphens (-).
  • In regular expression terms: "^[A-Za-z_]([A-Za-z0-9]*|[A-Za-z0-9][A-Za-z0-9_]*)$".
  • Cannot be more than 255 characters.
  • Are case insensitive. (Fields named foo and FOO in the same payload are considered duplicates.)

For example, {"temp_01": 29} or {"_temp_01": 29} are valid, but {"temp-01": 29}, {"01_temp": 29} or {"__temp_01": 29} are invalid in message payloads.

(structure)

Information about a message.

messageId -> (string)

The ID you want to assign to the message. Each messageId must be unique within each batch sent.

payload -> (blob)

The payload of the message. This can be a JSON string or a base64-encoded string representing binary data, in which case you must decode it by means of a pipeline activity.

Shorthand Syntax:

messageId=string,payload=blob ...

JSON Syntax:

[
  {
    "messageId": "string",
    "payload": blob
  }
  ...
]

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To send a message to a channel

The following batch-put-message example sends a message to the specified channel.

aws iotanalytics batch-put-message \
    --cli-binary-format raw-in-base64-out \
    --cli-input-json file://batch-put-message.json

Contents of batch-put-message.json:

{
    "channelName": "mychannel",
    "messages": [
        {
            "messageId": "0001",
            "payload": "eyAidGVtcGVyYXR1cmUiOiAyMCB9"
        }
    ]
}

Output:

{
    "batchPutMessageErrorEntries": []
}
