get-regex-pattern-set¶

Description¶

Retrieves the specified RegexPatternSet .

Synopsis¶

  get-regex-pattern-set
--name <value>
--scope <value>
--id <value>
[--cli-input-json | --cli-input-yaml]
[--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 Amazon CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB), an Amazon API Gateway REST API, an AppSync GraphQL API, or an Amazon Cognito user pool.

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 | --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 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.

RegularExpressionList -> (list)

The regular expression patterns in the set.

(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. 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 . 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.
