test-authorization¶

Description¶

Tests if a specified principal is authorized to perform an IoT action on a specified resource. Use this to test and debug the authorization behavior of devices that connect to the IoT device gateway.

Requires permission to access the TestAuthorization action.

Synopsis¶

  test-authorization
[--principal <value>]
[--cognito-identity-pool-id <value>]
--auth-infos <value>
[--client-id <value>]
[--policy-names-to-add <value>]
[--policy-names-to-skip <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--principal (string)

The principal. Valid principals are CertificateArn (arn:aws:iot:region :accountId :cert/certificateId ), thingGroupArn (arn:aws:iot:region :accountId :thinggroup/groupName ) and CognitoId (region :id ).

--cognito-identity-pool-id (string)

The Cognito identity pool ID.

--auth-infos (list)

A list of authorization info objects. Simulating authorization will create a response for each authInfo object in the list.

(structure)

A collection of authorization information.

actionType -> (string)

The type of action for which the principal is being authorized.

resources -> (list)

The resources for which the principal is being authorized to perform the specified action.

(string)

Shorthand Syntax:

actionType=string,resources=string,string ...

JSON Syntax:

[
  {
    "actionType": "PUBLISH"|"SUBSCRIBE"|"RECEIVE"|"CONNECT",
    "resources": ["string", ...]
  }
  ...
]

--client-id (string)

The MQTT client ID.

--policy-names-to-add (list)

When testing custom authorization, the policies specified here are treated as if they are attached to the principal being authorized.

(string)

Syntax:

"string" "string" ...

--policy-names-to-skip (list)

When testing custom authorization, the policies specified here are treated as if they are not attached to the principal being authorized.

(string)

Syntax:

"string" "string" ...

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

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 test your AWS IoT policies

The following test-authorization example tests the AWS IoT policies associated with the specified principal.

aws iot test-authorization \
    --auth-infos actionType=CONNECT,resources=arn:aws:iot:us-east-1:123456789012:client/client1 \
    --principal arn:aws:iot:us-west-2:123456789012:cert/aab1068f7f43ac3e3cae4b3a8aa3f308d2a750e6350507962e32c1eb465d9775

                        }

A list of policies that allowed the authentication.

(structure)

Describes an IoT policy.

policyName -> (string)

The policy name.

denied -> (structure)

(structure)

Describes an IoT policy.

policyName -> (string)

The policy name.

policyArn -> (string)

The policy ARN.

Information that explicitly denies the authorization.

policies -> (list)

The policies that denied the authorization.

(structure)

Describes an IoT policy.

policyName -> (string)

policyArn -> (string)

The policy ARN.

authDecision -> (string)
