AWS S3 Presigned SDK

Approach

Traditionally to upload a file from users to a private S3 bucket needs two internet connections. One is from client to your own server, and the other is from your server to S3 bucket. Using pre-signed upload can solve this problem. Your server issues pre-signed upload url for client to upload in advance, and the client can upload his file to S3 bucket directly within an authorized time period. This package wraps S3 pre-signed api for PHP and Laravel.

Installation

composer require unisharp/s3-presigned

Laravel 5

Setup

Add ServiceProvider and Facade in app/config/app.php.

Unisharp\S3\Presigned\S3PresignedServiceProvider::class,

'S3Presigned' => Unisharp\S3\Presigned\Facades\S3Presigned::class,

It supports package discovery for Laravel 5.5.
