Generate Temporary Signed URL from s3 in Laravel

What is AWS?

Amazon Web Services (AWS) is the world’s most comprehensive and broadly adopted cloud platform, offering over 200 fully-featured services from data centers globally.

Amazon Web Services is a subsidiary of Amazon providing on-demand cloud computing platforms and APIs to individuals, companies, and governments, on a metered pay-as-you-go basis.

What is AWS S3?

Amazon S3 or Amazon Simple Storage Service is a service offered by Amazon Web Services that provides object storage through a web service interface. Amazon S3 uses the same scalable storage infrastructure that Amazon.com uses to run its global e-commerce network.

Sometimes, all you want to do is generate temporary URLs for files that you have stored on your AWS S3 bucket. For instance, you would want to use this to prevent the hotlinking of images.

Laravel provides an easy way to do so. To create temporary URLs of files.

When you have stored files privately in Amazon s3 which you want to make public only for selected users for a limited amount of time, you can achieve that using the Storage facade in Laravel.

To create temporary files, you can use temporaryUrl method from the IlluminateSupportFacadeStorage facade. You can use the method on the following syntax.

use IlluminateSupportFacadesStorage;

$url = Storage::disk('s3')->temporaryUrl("filename.jpg", now()->addMinutes(5));

temporaryUrl method accepts two parameters as follows,

1. Path: This parameter accepts the full path of the file in the s3 bucket
2. Expiry Time: You can set the date for the expiry of the link.
3. you may pass the array of request parameters as the third argument to the temporaryUrl method. 

$url = Storage::disk('s3')->temporaryUrl(
    'filename.jpg',
    now()->addMinutes(5),
    [
        'ResponseContentType' => 'application/octet-stream',
        'ResponseContentDisposition' => 'attachment; filename=filename.jpg',
    ]
);
