How to access private s3 files using URI

• In AWS S3 bucket is mainly used to store files.
• To access S3 bucket files follow below steps.

• Provide access configuration using AWS.config() method as below.

  AWS.config.update({
  region: "us-east-2",
  signatureVersion: 'v4',
  credentials: new AWS.Credentials(AccessKey, AccesSecreteKey, token)
  });

• Later intitialize s3 variable using new AWS.S3()

  var s3 = new AWS.S3();

  To get access URI of the file we use getSignedUrl() method of s3 bucket Here we have three parameters

• Bucket:Name of the Bucket
• Key: Path inside the Bucket
• Expires: No of seconds the required to enable the URI(maximum 1 week)

var presignedURI = s3.getSignedUrl('getObject', {
   Bucket: "Bucket_Name",
   Key: "FIle_Path",
   Expires: seconds
});
console.log(presignedURI);

Here presignedURI variable provides the URL,we can access the file using this URL
