Download from Amazon S3 using JavaScript and Visualforce

Saurabh Dua 15:32 Amazon S3 , Integration Edit

In continuation to the post where I explained how to upload to Amazon S3 using Javascript , this post will focus on downloading the document from Amazon S3 using native JavaScript and Visualforce page.

Copy and paste the below JavaScript code in the VF page which would enable you to download the specified file. Change the text mentioned in Red

<script src="https://sdk.amazonaws.com/js/aws-sdk-2.1.12.min.js"></script>

<script type="text/javascript">

AWS.config.update(
{
accessKeyId: "YOUR AWS ACCESS KEY ID",
secretAccessKey: "YOUR AWS SECRET ACCESS KEY",
region_config: "eu-west-1"
}
);
var s23 = new AWS.S3();
var y="Name of the file which is to be downloaded";

var params = {Bucket: 'BUCKET NAME', Key: y};
s23.getSignedUrl('getObject', params, function (err, url) {
window.open(url,"_self");
});
</script>

If you have any question don't hesitate to mention them in comments!!
