Inserts or deletes RegexMatchTuple objects (filters) in a RegexMatchSet.
For each RegexMatchSetUpdate
object, you specify the following values:
waf_update_regex_match_set(RegexMatchSetId, Updates, ChangeToken)
[required] The RegexMatchSetId
of the RegexMatchSet that you want to update.
RegexMatchSetId
is returned by CreateRegexMatchSet and by
ListRegexMatchSets.
[required] An array of RegexMatchSetUpdate
objects that you want to insert into
or delete from a RegexMatchSet. For more information, see
RegexMatchTuple.
[required] The value returned by the most recent call to GetChangeToken.
svc$update_regex_match_set( RegexMatchSetId = "string", Updates = list( list( Action = "INSERT"|"DELETE", RegexMatchTuple = list( FieldToMatch = list( Type = "URI"|"QUERY_STRING"|"HEADER"|"METHOD"|"BODY"|"SINGLE_QUERY_ARG"|"ALL_QUERY_ARGS", Data = "string" ), TextTransformation = "NONE"|"COMPRESS_WHITE_SPACE"|"HTML_ENTITY_DECODE"|"LOWERCASE"|"CMD_LINE"|"URL_DECODE", RegexPatternSetId = "string" ) ) ), ChangeToken = "string" )
Whether to insert or delete the object from the array. If you want
to change a RegexMatchSetUpdate
object, you delete the existing
object and add a new one.
The part of a web request that you want AWS WAF to inspectupdate,
such as a query string or the value of the User-Agent
header.
The identifier of the pattern (a regular expression) that you want AWS WAF to look for. For more information, see RegexPatternSet.
Whether to perform any conversions on the request, such as converting it to lowercase, before inspecting it for the specified string.
For example, you can create a RegexPatternSet
that matches any
requests with User-Agent
headers that contain the string
B\[a@\]dB\[o0\]t
. You can then configure AWS WAF to reject those
requests.
To create and configure a RegexMatchSet
, perform the following steps:
Create a RegexMatchSet.
For more information, see
CreateRegexMatchSet.
Use GetChangeToken to get the change token that you provide in the
ChangeToken
parameter of an UpdateRegexMatchSet
request.
Submit an UpdateRegexMatchSet
request to specify the part of the
request that you want AWS WAF to inspect (for example, the header or
the URI) and the identifier of the RegexPatternSet
that contain
the regular expression patters you want AWS WAF to watch for.
For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.
