IoTDataPlane

Client

class IoTDataPlane.Client

A low-level client representing AWS IoT Data Plane:

client = session.create_client('iot-data')

These are the available methods:

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
delete_thing_shadow(**kwargs)

Deletes the thing shadow for the specified thing.

For more information, see DeleteThingShadow in the AWS IoT Developer Guide .

See also: AWS API Documentation

Request Syntax

response = client.delete_thing_shadow(
    thingName='string'
)
Parameters
thingName (string) --

[REQUIRED]

The name of the thing.

Return type
dict
Returns
Response Syntax
{
    'payload': StreamingBody()
}

Response Structure

  • (dict) --

    The output from the DeleteThingShadow operation.

    • payload (StreamingBody) --

      The state information, in JSON format.

Exceptions

generate_presigned_url(ClientMethod, Params=None, ExpiresIn=3600, HttpMethod=None)

Generate a presigned url given a client, its method, and arguments

Parameters
  • ClientMethod (string) -- The client method to presign for
  • Params (dict) -- The parameters normally passed to ClientMethod.
  • ExpiresIn (int) -- The number of seconds the presigned url is valid for. By default it expires in an hour (3600 seconds)
  • HttpMethod (string) -- The http method to use on the generated url. By default, the http method is whatever is used in the method's model.
Returns

The presigned url

get_paginator(operation_name)

Create a paginator for an operation.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Raises OperationNotPageableError
Raised if the operation is not pageable. You can use the client.can_paginate method to check if an operation is pageable.
Return type
L{botocore.paginate.Paginator}
Returns
A paginator object.
