FieldToMatch (dict) --
Specifies where in a web request to look for TargetString.
Type (string) --
The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:
HEADER: A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data.
METHOD: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.
QUERY_STRING: A query string, which is the part of a URL that appears after a ? character, if any.
URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.
BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.
Data (string) --

{'Updates': {'Predicate': {'Type': {'XssMatch'}}}}
Inserts or deletes Predicate objects in a Rule. Each Predicate object identifies a predicate, such as a ByteMatchSet or an IPSet, that specifies the web requests that you want to allow, block, or count. If you add more than one predicate to a Rule, a request must match all of the specifications to be allowed, blocked, or counted. For example, suppose you add the following to a Rule:
A ByteMatchSet that matches the value BadBot in the User-Agent header
An IPSet that matches the IP address 192.0.2.44
You then add the Rule to a WebACL and specify that you want to block requests that satisfy the Rule. For a request to be blocked, the User-Agent header in the request must contain the value BadBot and the request must originate from the IP address 192.0.2.44.
To create and configure a Rule, perform the following steps:
Create and update the predicates that you want to include in the Rule.
Create the Rule. See CreateRule.
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRule request.
Submit an UpdateRule request to add predicates to the Rule.
Create and update a WebACL that contains the Rule. See CreateWebACL.
If you want to replace one ByteMatchSet or IPSet with another, you delete the existing one and add the new one.
