Class SkillStreamHandler

java.lang.Object

com.amazon.ask.SkillStreamHandler

All Implemented Interfaces:

com.amazonaws.services.lambda.runtime.RequestStreamHandler

public abstract class SkillStreamHandler
extends Object
implements com.amazonaws.services.lambda.runtime.RequestStreamHandler

This class provides the handler required when hosting the service as an AWS Lambda function.

Lambda functions written in Java must have a RequestStreamHandler class for the handler. That handler must include a zero argument constructor and implement RequestStreamHandler.

The SkillStreamHandler abstract class can be used to create such a class that extends RequestStreamHandler

When configuring your Lambda function in the AWS Lambda console, specify your new class as the Handler.

Method Detail

handleRequest

public final void handleRequest(InputStream input,
                                OutputStream output,
                                com.amazonaws.services.lambda.runtime.Context context)
                         throws IOException

This method is the primary entry point when executing your Lambda function. The configured SkillStreamHandler determines the type of request and passes the request to the configured Skill.

Any errors that occur in either the Skill or the SkillStreamHandler are converted into a RuntimeException, causing the Lambda call to fail. Details on the failure are then available in the Lambda console logs within CloudWatch.
