Gets a list of all of the context keys referenced in the input policies. The policies are supplied as a list of one or more strings. To get the context keys from policies associated with an IAM user, group, or role, use GetContextKeysForPrincipalPolicy.
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 specified in an IAM policy. Use
to understand what key names and values you must supply when you call SimulateCustomPolicy.
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.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginGetContextKeysForCustomPolicy and EndGetContextKeysForCustomPolicy. For Unity the operation does not take CancellationToken as a parameter, and instead takes AmazonServiceCallback<GetContextKeysForCustomPolicyRequest, GetContextKeysForCustomPolicyResponse> and AsyncOptions as additional parameters.
public virtual Task<GetContextKeysForCustomPolicyResponse> GetContextKeysForCustomPolicyAsync( List<String> policyInputList, CancellationToken cancellationToken )
A list of policies for which you want the list of context keys referenced in those policies. Each document is specified as a string containing the complete, valid JSON text of an IAM policy.
