Modify Attributes Advice

Note: this component stores cluster-wide configuration data and is mirrored across all servers in the topology within the the same cluster.

Note: changes to cluster-wide configuration objects are immediately and automatically mirrored across all servers within the same cluster, so offline changes are not supported.

Advice that allows a policy writer to modify attributes of a request or response body based on policy decisions.

The payload for this advice is a JSON object. Each key on the object will be interpreted as a JSONPath, and the attribute at that path will be given a value of the object's value at that key.

For example, given a body of {"foo": "bar", "a": "b"} and a payload of {"$.a": "c"}, the resulting body will be {"foo": "bar", "a": "c"}.

This advice may create an attribute, if its enclosing object or array already exists. For example, given a body of {"foo": {"bar": "baz"}, "a": "b"} and a payload of {"$.foo.foo", "foobar"}, the resulting object will be {"foo: {"bar: "baz", "foo": "foobar"}, "a": "b"}.

However, if the enclosing object does not exist, the path will be ignored, as with a body of {"foo: "bar", "x": "y"} and a payload of {"$.x.y.z", "foo"}.
