See 'aws help' for descriptions of global parameters.

Synopsis

  get-regex-pattern-set
--name <value>
--scope <value>
--id <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--name (string)

The name of the set. You cannot change the name after you create the set.

--scope (string)

Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB) or an API Gateway stage.

To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:

  • CLI - Specify the Region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .
  • API and SDKs - For all calls, use the Region endpoint us-east-1.

Possible values:

  • CLOUDFRONT
  • REGIONAL

--id (string)

A unique identifier for the set. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

--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.

Examples

To retrieve a specific regex pattern set

The following get-regex-pattern-set retrieves the regex pattern set with the specified name, scope, region, and ID. You can get the ID for a regex pattern set from the commands create-regex-pattern-set and list-regex-pattern-sets.

aws wafv2 get-regex-pattern-set \
    --name regexPatterSet01 \
    --scope REGIONAL \
    --id a1b2c3d4-5678-90ab-cdef-EXAMPLE11111 \
    --region us-west-2

Output:

{
    "RegexPatternSet":{
        "Description":"Test web-acl",
        "RegularExpressionList":[
            {
                "RegexString":"/[0-9]*/"
            },
            {
                "RegexString":"/[a-z]*/"
            }
        ],
        "Name":"regexPatterSet01",
        "ARN":"arn:aws:wafv2:us-west-2:123456789012:regional/regexpatternset/regexPatterSet01/a1b2c3d4-5678-90ab-cdef-EXAMPLE11111",
        "Id":"a1b2c3d4-5678-90ab-cdef-EXAMPLE11111"
    },
    "LockToken":"c8abf33f-b6fc-46ae-846e-42f994d57b29"
}

Output

RegexPatternSet -> (structure)

Name -> (string)

The name of the set. You cannot change the name after you create the set.

Id -> (string)

A unique identifier for the set. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

ARN -> (string)

The Amazon Resource Name (ARN) of the entity.

Description -> (string)

A description of the set that helps with identification. You cannot change the description of a set after you create it.

(structure)

A single regular expression. This is used in a RegexPatternSet .

RegexString -> (string)

The string representing the regular expression.

LockToken -> (string)

A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.
