JwtUserIdKeyResolver (lambda-native 2.1.36 API)

java.lang.Object
- com.networknt.aws.lambda.handler.middleware.limit.key.JwtUserIdKeyResolver

All Implemented Interfaces:

KeyResolver
```
public class JwtUserIdKeyResolver
extends Object
implements KeyResolver
```
When user is selected as the key, we can get the user_id from the JWT claim. In this way, we can limit a number of requests for a user to prevent abuse from a single page application that is using the backend APIs.
