I see. My goal was to be able to send this link to a client webpage and allow the end-user to click on a link to download the protected file. However, based on what you're saying I'd need the client to make an AJAX request but then there is no good way of downloading a file via AJAX get request. Can not download the image with s3 getSignedUrl ('getObject ..) and return Signature does not match I'm relatively new to AWS. All I was trying to do is to upload image from my app to aws S3 and download it to view the image in another page in app. The upload was successful and was able to see the uploaded image in S3. But couldn't download it as i Before we upload the file, we need to get this temporary URL from somewhere. Where exactly is described in the following architecture (click to enlarge); We are going to build a ReactJS application that allows you to upload files to an S3 bucket. First, it gets the pre-signed URL through AWS API Gateway from a Lambda function. We only want @binoculars The reason there is a callback option is because the getSignedUrl method will asynchronously refresh credentials if they are expired. Calling getSignedUrl without a callback will return the url directly, but this can be unsafe if your credentials can expire.. I agree that we should also allow for getSignedUrl to return a promise. The way this currently works for other operations is that the request object returned by an operation can then have promise() called on it.getSignedUrl GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together Example browser script that shows how to view and manipulate photo albums and photos in Amazon S3 buckets.

Step 1: First of all we need to install aws-sdk-js in our project. bower install aws-sdk-js AWS SDK for JavaScript in the browser and Node.js. Contribute to aws/aws-sdk-js development by creating an account on GitHub. SSEKMSKeyId *string `location:"header" locationName:"x-amz-server-side-encryption-aws-kms-key-id" type:"string" sensitive:"true"` // If you specified server-side encryption either with an Amazon S3-managed // encryption key or an AWS KMS customer master key (CMK) in your initiate multipart // upload request, the response includes this header. If you download one file at a time (basically run the code above with 1 concurrent download serially for each file), that should be pretty safe. However, if you have a lot of small files and/or light compression, this will probably be quite a bit slower. If you have large files and/or heavy compression, I would guess it would not be much slower.
I am using the NodeJS AWS SDK to generate a presigned S3 URL. The docs give an example of doing something wrong with how I'm using the SDK.
A short guide to building a practical YouTube MP3 downloader bookmarklet using Amazon Lambda. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload.
