ForAllValues:StringLikeIfExists
Warning:
ForAllValues:
StringLikeIfExists
is actively confusing. Any operator starting with
ForAllValues
will ignore IfExists
.
IfExists
is not evaluated against the entire array, it is only evaluated
against a single value at a time, inside the ForAllValues
loop.
This is the kind of thing Jacob would do. Use
ForAllValues:
StringLike
instead so your coworkers don't hate you.
ForAllValues: StringLikeIfExists
ForAllValues:
StringLikeIfExists
compares a list of strings in a request to a list of strings in your policy. The policy values can include asterisks (*) to match multiple characters and question marks (?) to match a single character. The comparision is case sensitive.
To match a request, the context key can be absent, but if it is present, all of the strings in the request must match at least one of the strings in your policy.
You can use policy variables in the value of this operator.
