getContextKeysForPrincipalPolicy method
Gets a list of all of the context keys referenced in all the IAM policies that are attached to the specified IAM entity. The entity can be an IAM user, group, or role. If you specify a user, then the request also includes all of the policies attached to groups that the user is a member of.
You can optionally include a list of one or more additional policies, specified as strings. If you want to include only a list of policies by string, use GetContextKeysForCustomPolicy instead.
Note: This API discloses information about the permissions granted to other users. If you do not want users to see other user's permissions, then consider allowing them to use GetContextKeysForCustomPolicy instead.
Context keys are variables maintained by AWS and its services that provide details about the context of an API query request. Context keys can be evaluated by testing against a value in an IAM policy. Use GetContextKeysForPrincipalPolicy to understand what key names and values you must supply when you call SimulatePrincipalPolicy.
May throw NoSuchEntityException. May throw InvalidInputException.
Parameter policySourceArn
:
The ARN of a user, group, or role whose policies contain the context keys
that you want listed. If you specify a user, the list includes context
keys that are found in all policies that are attached to the user. The
list also includes all groups that the user is a member of. If you pick a
group or a role, then it includes only those context keys that are found
in policies attached to that entity. Note that all parameters are shown in
unencoded form here for clarity, but must be URL encoded to be included as
a part of a real HTML request.
For more information about ARNs, see Amazon Resource Names (ARNs) and AWS Service Namespaces in the AWS General Reference.
Parameter policyInputList
:
An optional list of additional policies for which you want the list of
context keys that are referenced.
The regex pattern used to validate this parameter is a string of characters consisting of the following:
-
Any printable ASCII character ranging from the space character
(
\u0020
) through the end of the ASCII character range -
The printable characters in the Basic Latin and Latin-1 Supplement
character set (through
\u00FF
) -
The special characters tab (
\u0009
), line feed (\u000A
), and carriage return (\u000D
)
