Sends messages to a channel.

See 'aws help' for descriptions of global parameters.

--channel-name <value>
--messages <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]
--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. EachmessageId
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.
See 'aws help' for descriptions of global parameters.
To send a message to a channel
The following batch-put-message
example sends a message to the specified channel.
