Step 3: Create a Lambda
function
In this section you create a Lambda function using a blueprint (lex-book-trip-python) provided in the AWS Lambda console. You also test the Lambda function by invoking it using sample event data provided by the console.
This Lambda function is written in Python.
-
Sign in to the AWS Management Console and open the AWS Lambda console at https://console.aws.amazon.com/lambda/
. -
Choose Create function.
-
Choose Use a blueprint. Type
lexto find the blueprint, choose thelex-book-trip-pythonblueprint. -
Choose Configure the Lambda function as follows.
-
Type a Lambda function name (
BookTripCodeHook). -
For the role, choose Create a new role from template(s) and then type a role name.
-
Leave the other default values.
-
-
Choose Create function.
-
If you are using a locale other than English (US) (en-US), update the intent names as described in Updating a Blueprint for a Specific Locale.
-
Test the Lambda function. You invoke the Lambda function twice, using sample data for both booking a car and booking a hotel.
-
Choose Configure test event from the Select a test event drop down.
-
Choose Amazon Lex Book Hotel from the Sample event template list.
This sample event matches the Amazon Lex request/response model. For more information, see Using Lambda Functions.
-
Choose Save and test.
-
Verify that the Lambda function ran successfully. The response in this case matches the Amazon Lex response model.
-
Repeat the step. This time you choose the Amazon Lex Book Car from the Sample event template list. The Lambda function processes the car reservation.
-
