Thanks for the video. I was pulling my hair to get this thing done using PHP SDK. Your video helped indirectly.

If you just specify the main bucket, can you just access the file by name, or do you have to append the pseudo folder structure to the file name as well?

I would much appreciate it if you make tutorials using node js SDK v3.

Can you please tell me how do I upload multiple images to S3 using node.js. I want to upload them and delete them. If you give me a solution it will be really helpful. Thank you

[@rogeracg]

Thanks for the video !
The image returns it as binary, right?
Is there a way to return the image in PNG format for example, instead of returning the image code?

[@BiteSizeAcademy]

You can use something like ImageMagick to convert to png: imagemagick.org/script/convert.php
Also check out this video about how to use ImageMagick with a Lambda function on AWS: czcams.com/video/JdJo-_Y1ZIM/video.html

Hi!
I have a problem tho. I can get my presigned url without problem. The problem is that even the element on S3 doesn exist the service will create an url. Just when you enter into the url you can see the msg that say "the key doesn exist".
Any form to catch this? Because is not an error of the service, is just an url with permission trying to access to the object itself
Thanks!

Something I don't understand: this generates a presigned URL based on MY access credentials. What if I have a full stack app where users authenticate themselves using Cognito user pool and obtain the related tokens. Am I able to use those to make the subsequent requests to S3?

[@harithauidev6353]

is this for private S3 bucket.. I am trying to access Private bucket and this doesnt work?

[@eduardoorm]

Hey bro, when I open the url in the browser, the file is downloaded but it doesn't show it

[@rogeracg]
