pre-signed-url

The thing I want to achieve is to generate a singedURL pointing CloudFront distribution which originates from S3 bucket. I have managed to sign the URL which points directly to the S3 bucket as described in following AWS spec - Generate a Presigned Object URL Using AWS SDK for .NET and it worked fine. But what I really need is to generate signed CloudFront URL. I assume my Distribution is properly configured as I'm able to access it using ( https://d298o8yem5c56d.cloudfront.net/123.pdf ) assuming Restrict Viewer Access: is set to No in Behaviors settings. After switching it to Yes it can no

I generated the url similar to this for my users to retrieve image files from my aws s3 bucket: https://resource.my-company.com/tYERrR13341/q1/something.jpg?response-expires=Thu%2C%2008%20Nov%202018%2007%3A26%3A21%20GMT&AWSAccessKeyId=TTKIAJJBATJ89740989&Expires=1541661981&Signature=J49ebmKMdZ%2FZqwupfaD39f9e716831 Sometimes a user may refresh the page and the url to the same resource get a new set of values for Expires and Signature . The browser will treat these two urls as different two objects, and will try to download the resource from the s3 bucket again. It causes some performance issue

I am trying to upload video files to a Bucket in S3 server from android app using a signed URLs which is generated from server side (coded in python) application. We are making a PUT request to the signed URL but we are getting connection reset by peer exception . But when I try the same URL on the POSTMAN REST CLIENT get a success message. Any help will be appreciated. Done this using Retrofit HTTP client library,it successfully uploaded file to Amazon s3 server. code: public interface UploadService { String BASE_URL = "https://bucket.s3.amazonaws.com/folder"; /** * @param url :signed s3 url

According to this link http://docs.aws.amazon.com/aws-sdk-php/v2/guide/service-s3.html , I can easily create a presigned link just adding the life span to getObjectUrl $signedUrl = $client->getObjectUrl($bucket, 'data.txt', '+10 minutes'); // > https://my-bucket.s3.amazonaws.com/data.txt?AWSAccessKeyId=[...]&Expires=[...]&Signature=[...] But I get a plain url, you know, without the awsaccesskeyid and expires parameters, Here's my code: $bucket = 'imagenesfc'; $keyname = 'NASimagenes/codigoBarraBoleto/1001000098.png'; $filepath = 'NASimagenes/codigoBarraBoleto'; // Instantiate the client. $s3 =

In Brief In order to keep the uploaded media (S3 objects) private for all the clients on my multi-tenant system I implemented a Cloudfront CDN deployment and configured it (and its Origin S3 Bucket) to force the use of signed URLs in order to GET any of the objects. The Method First, the user is authenticated via my system, and then a signed URL is generated and returned to them using the AWS.CloudFront.Signer.getSignedUrl() method provided by the AWS JS SDK . so they can make the call to CF/S3 to download the object (image, PDF, docx, etc). Pretty standard stuff. The Problem The above method

I am using cordova file transfer to dowload a file from aws s3 using signed url, since cordova filetransfer encodes the uri, the "%" in signature is converted to "%25", thus, results in signature mismatch Try setting up your options like so: options = { fileKey: 'file', fileName: name, chunkedMode: false, mimeType: 'audio/3gpp', httpMethod: 'PUT', // Important! headers: { 'Content-Type': 'audio/3gpp' // < Set explicitly otherwise it becomes multipart/form-data which won't work with S3 }, encodeURI: false // < Stops any extra encoding by file transfer logic } Took me many painful hours getting
