AWS File Upload to S3 with Java

Question

I am trying to upload files into my S3 bucket using AWS Lambda in Java and i'm having some issues.

I am using APIGatewayProxyRequestEvent in my AWS Lambda function to get my file upload from Postman .

request.getBody() method of this event gives me a String representation of the image file whereas the S3.putObject takes as input an InputStream of the file to be uploaded.

How can I feed in request.getBody() to the S3.putObject() method in my Lambda code to make the File Upload work?

Answer 1

1) You may create a File and using FileWriter you may write the request.getBody() into it. 2) You can go with PutObjectRequest object and put file created in Step1 into it. 3) s3Client.putObject(PutObjectRequest) will help you to put object to s3
