[AWS Lambda] Use AWS Lambda and API Gateway to return data

In this lesson, you will learn how to create a simple AWS Lambda function to submit a name via an API Gateway and return a resume for that person. At the end of the lesson, you will be able to create a Lambda function, and API Gateway, and understand how to submit data via the API Gateway that will be accessible via the Lambda function

1. Go to Lambda, create a new function. You can skip the blueprint.

2. Enter the function name: "getResume" and code:

exports.handler = function(event, context){
    var resume = {};
    resume.firstName = event.firstName;
    resume.lastName = event.lastName;

    resume.workHistory = [
        {
            companyName: "Make Helsinki",
            period: 1
        },
        {
            companyName: "Tecnotree Oy",
            period: 1
        }
    ];

    context.succeed(resume);
}

event: Hold the param you send in.

context: call succeed() function to return the data.

3. You can test your function:

4. Then go to the AWS dashboard, click API Getway, create a new gateway:

5. Create a post request which intergate with Lambad function we just created:

6. You can test the api.

7. Deploy API:

8. Finally, you can use Postman, to test the api.
