Overview
When passing RegexPatternSetReferenceStatement as input to an Aws::Client method, you can use a vanilla Hash:
{
arn: "ResourceArn", # required
field_to_match: { # required
single_header: {
name: "FieldToMatchData", # required
},
single_query_argument: {
name: "FieldToMatchData", # required
},
all_query_arguments: {
},
uri_path: {
},
query_string: {
},
body: {
},
method: {
},
},
text_transformations: [ # required
{
priority: 1, # required
type: "NONE", # required, accepts NONE, COMPRESS_WHITE_SPACE, HTML_ENTITY_DECODE, LOWERCASE, CMD_LINE, URL_DECODE
},
],
}
This is the latest version of AWS WAF, named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide.
A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet.
Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.

#field_to_match ⇒ Types::FieldToMatch
The part of a web request that you want AWS WAF to inspect.
-
#text_transformations ⇒ Array<Types::TextTransformation>
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Instance Attribute Details
#arn ⇒ String
The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.
#field_to_match ⇒ Types::FieldToMatch
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch.
#text_transformations ⇒ Array<Types::TextTransformation>
Text transformations eliminate some of the unusual formatting that
attackers use in web requests in an effort to bypass detection. If you
specify one or more transformations in a rule statement, AWS WAF
performs all transformations on the content of the request component
identified by FieldToMatch
, starting from the lowest priority setting,
before inspecting the content for a match.
