AWS S3 file upload using cakephp 3 - php

Question

I'm trying to implement file upload to amazon s3. I'm getting following error
Cannot redeclare GuzzleHttp\uri_template() (previously declared in /var/www/html/appname/vendor/guzzlehttp/guzzle/src/functions‌​.php:17) File /var/www/html/appname/vendor/aws/GuzzleHttp/functions.php
In upload controller, using below code to upload
require_once("../vendor/aws/aws-autoloader.php");
use Aws\S3\S3Client;
public function upload(){
$s3 = S3Client::factory(array( 'version' =>
'latest', 'region' => 'ap-south-1', 'credentials' => array(
'key' => 'key',
'secret' => 'secret' ) ));
if ($this->request->is('post'))
{
if(!empty($this->request->data['file']['name']))
{
$fileName = $this->request->data['file']['name'];
$s3->putObject([
'Bucket' => backetname,
'Key' => $fileName,
'SourceFile' => $this->request->data['file']['tmp_name'],
'ContentType' => 'image/jpeg',
'ACL' => 'public-read',
'StorageClass' => 'REDUCED_REDUNDANCY'
]);
}
}
}

Answer 1

You are creating an object of S3 client outside of the method which is the reason that $s3 in method is null.
Either you need to create object in method itself or you can store the S3 client object in class property and use with $this->s3->putObject()
Better would be to create a component, something like below:
<?php
namespace App\Controller\Component;
use Cake\Controller\Component;
use Aws\S3\S3Client;
class AmazonComponent extends Component{
public $config = null;
public $s3 = null;
public function initialize(array $config){
parent::initialize($config);
$this->config = [
's3' => [
'key' => 'YOUR_KEY',
'secret' => 'YOUR_SECRET',
'bucket' => 'YOUR_BUCKET',
]
];
$this->s3 = S3Client::factory([
'credentials' => [
'key' => $this->config['s3']['key'],
'secret' => $this->config['s3']['secret']
],
'region' => 'eu-central-1',
'version' => 'latest'
]);
}
}
And use this component in your controller. Example below:
class UploadController extends AppController{
public $components = ['Amazon'];
public function upload(){
$objects = $this->Amazon->s3->putObject([
'Bucket' => backetname,
'Key' => $fileName,
'SourceFile' => $this->request->data['file']['tmp_name'],
'ContentType' => 'image/jpeg',
'ACL' => 'public-read',
'StorageClass' => 'REDUCED_REDUNDANCY'
]);
}
}
