Upload file to AWS S3 Bucket Using Presigned URL In JAVA | Amazon S3 PUT using Presigned URL

Hello friends.
I am Lipsa Patra. I am a software engineer. Welcome to my youtube channel
Easy 2Excel .
In this video tutorial we will learn how to upload file to AWS S3 using Presigned URL in java.
Pre-Signed URLs are URLs that have limited permissions and expiry any client can use that URL to PUT the file directly to s3 without the need to worry about the AWS access key and secret.
First, we will create a REST API will our frontend will call and
we will create a Pre-Signed URL with limited permissions and return back to the frontend.The front end will directly upload the file to s3.
You can download the entire source code from the below link.

when trying to upload a file using postman, it gives an error - The request signature we calculated does not match the signature you provided. Check your key and signing method. are there any extra configurations we need to pass in for using postman ?

Hi.. nice explanation. I'm thinking of allowing my customer to upload multiple files with a single presigned URL. is that possible?
Can we open this presigned URL in the browser to upload files?
