Set Private files to Public Amazon S3 - php

Is it possible to convert from private s3 files in bucket to public using PHP library provided by Amazon AWS S3?

All you need to do is set the ACL to public-read, you can do this with the PHP SDK using the update_object() function.
$s3 = new AmazonS3();
$bucket = 'my-bucket' . strtolower($s3->key);
$response = $s3->update_object($bucket, 'test1.txt', array(
'acl' => AmazonS3::ACL_PUBLIC
));

Upload image to AWS bucket from remote server

I have a web application in PHP up and running. I want this app capable of uploading images to AWS s3 bucket. I am checking the documentation at AWS, but found at least three different documentations for this purpose. But still I am not clear, is possible that my web app hosted with a different hosting service will be able to upload files to AWS ?
If yes, which is the best option ?
You should be able to upload from outside of the AWS network.
Use the AWS PHP SDK at https://aws.amazon.com/sdk-for-php/
Then use the following code:
<?php
require 'vendor/autoload.php';
use Aws\Common\Exception\MultipartUploadException;
use Aws\S3\MultipartUploader;
use Aws\S3\S3Client;
$bucket = '*** Your Bucket Name ***';
$keyname = '*** Your Object Key ***';
$s3 = new S3Client([
'version' => 'latest',
'region' => 'us-east-1'
]);
// Prepare the upload parameters.
$uploader = new MultipartUploader($s3, '/path/to/large/file.zip', [
'bucket' => $bucket,
'key' => $keyname
]);
// Perform the upload.
try {
$result = $uploader->upload();
echo "Upload complete: {$result['ObjectURL']}" . PHP_EOL;
} catch (MultipartUploadException $e) {
echo $e->getMessage() . PHP_EOL;
}
?>
Edit the bucket name, keyname, region and upload file name.
This is the multi-part upload style so you can upload huge files.

Upload PDF file on Google Cloud Storage with mpdf library

I am using mpdf library to convert HTML to PDF and successfully stored my pdf file on local as well as remote server. But I don't want to store my pdf files on my code repos on server and like to utilize storage bucket available on google cloud.
/*
*/
private function generatePDF($params, $quotationId) {
$location = '/var/www/html/development/pdfs/';
$html = $this->load->view('quotation', $data, TRUE);
$filename = "quo_" .time() . ".pdf";
$mpdf = new \Mpdf\Mpdf(['mode' => 'en-IN', 'format' => 'A4']);
$mpdf->WriteHTML($html);
$mpdf->SetHTMLFooter('<p style="text-align: center; text-size: 12px;">This is computer generated quotation. It does not require signature.</p>');
$pdf = $mpdf->Output($location . $filename, 'F');
$this->UploadModel->upload($pdf, $filename);
}
public function upload($pdf, $pdfName) {
$storage = new StorageClient();
$bucket = $storage->bucket("bucketname");
$object = $bucket->upload($pdf, ['name' => $pdfName]);
$object = $bucket->object($pdfName);
$object->update(['acl' => []], ['predefinedAcl' => 'PUBLICREAD']);
}
Here I have used 'F' type in which it saves the pdf file in pdfs folder created in my code repo hosted on cloud server but I would like to directly store it to Google cloud storage bucket.
I am not having much experience about google cloud and mpdf library so looking for help and guidance to achieve the functionality.
Please kindly help me.
I see you are using Cloud Storage Client Libraries for PHP.
First, you need to install it to your machine:
composer require google/cloud-storage
And then you need to set up authentication by following the guide.
Once these are set create a bucket to store the PDFs.
Then replace your upload function with the code from the documentation:
use Google\Cloud\Storage\StorageClient;
/**
* Upload a file.
*
* #param string $bucketName the name of your Google Cloud bucket.
* #param string $objectName the name of the object.
* #param string $source the path to the file to upload.
*
* #return Psr\Http\Message\StreamInterface
*/
function upload_object($bucketName, $objectName, $source)
{
$storage = new StorageClient();
$file = fopen($source, 'r');
$bucket = $storage->bucket($bucketName);
$object = $bucket->upload($file, [
'name' => $objectName
]);
printf('Uploaded %s to gs://%s/%s' . PHP_EOL, basename($source), $bucketName, $objectName);
}
i also faced same issue & came out with this solution, i hope it will help you.
use 'S' instead of 'F'parameter, so it will return string data & pass this data directly into upload method.

how do i upload a file to a directory in google cloud storage using Google_Client library

i want to upload a file to google cloud storage using google client php library on github. Am able to upload file to cloud storage but am not able to upload to a directory in cloud storage. i get the error message No such object: bucketName/abc/test.jpg
$client = new Google_Client();
putenv('GOOGLE_APPLICATION_CREDENTIALS=files/google_cloud.json');
$client->useApplicationDefaultCredentials();
$storage = new Google\Cloud\Storage\StorageClient([
'projectId' => $googleprojectID
]);
$sPath = "files/com/test.jpg";
$objectName = "/abc/test.jpg";
$bucketName = $googlebucketName;
$bucket = $storage->bucket($bucketName);
$bucket->upload( fopen($sPath, 'r') );
$object = $bucket->object($objectName);
$info = $object->update(['acl' => []], ['predefinedAcl' => 'PUBLICREAD']);
First of all, let me share with you this documentation page where you will find the complete reference for the Google Cloud Storage PHP Client Library. More specifically, if you have a look at the upload() method, you will see that in order to set the name of the object uploaded (and therefore its location, given that GCS has a flat namespace), you have to use the options parameter, which can contain a name field pointing to the right location to upload.
Also, note that the correct object name should not start with a slash /, given that it will automatically be added after the bucket name. Therefore, you should modify your code to add something like this:
$sPath = "files/com/test.jpg";
$objectName = "abc/test.jpg"; # Note the removal of "/" here
$options = [
'name' => $objectName
];
$bucketName = $googlebucketName;
$bucket = $storage->bucket($bucketName);
$bucket -> upload(
fopen($sPath, 'r'),
$options
);

uploading posted file to amazon s3

I'm trying to upload a file to Amazon S3 via Laravel 4.
After user submit a form, the file will be passed to a function where I need to use Amazon PHP SDK and upload the file to Amazon S3 bucket.
But how do I upload the file straight away to Amazon S3 without saving the file onto server.
My current code looks like this,
private function uploadVideo($vid){
$file = $vid;
$filename = $file->getClientOriginalName();
if (!class_exists('S3'))require_once('S3.php');
if (!defined('awsAccessKey')) define('awsAccessKey', '123123123');
if (!defined('awsSecretKey')) define('awsSecretKey', '123123123');
$s3 = new S3(awsAccessKey, awsSecretKey);
$s3->putBucket("mybucket", S3::ACL_PUBLIC_READ);
$s3->putObject($vid, "mybucket",$filename , S3::ACL_PUBLIC_READ);
}
Grab the official SDK from http://docs.aws.amazon.com/aws-sdk-php/latest/index.html
This example uses http://docs.aws.amazon.com/aws-sdk-php/latest/class-Aws.S3.S3Client.html#_upload
require('aws.phar');
use Aws\S3\S3Client;
use Aws\Common\Enum\Region;
// Instantiate the S3 client with your AWS credentials and desired AWS region
$client = S3Client::factory(array(
'key' => 'KEY HERE',
'secret' => 'SECRET HERE',
'region' => Region::AP_SOUTHEAST_2 // you will need to change or remove this
));
$result = $client->upload(
'BUCKET HERE',
'OBJECT KEY HERE',
'STRING OF YOUR FILE HERE',
'public-read' // public access ACL
);

Delete object or bucket in Amazon S3?

I created a new amazon bucket called "photos". The bucket url is something like:
www.amazons3.salcaiser.com/photos
Now I upload subfolders containing files, into that bucket for example
www.amazons3.salcaiser.com/photos/thumbs/file.jpg
My questions are, does thumbs/ is assumed a new bucket or is it an object?
Then if I want to delete the entire thumbs/ directory need I first to delete all files inside that or can I delete all in one time?
In the case you are describing, "photos" is the bucket. S3 does not have sub-buckets or directories. Directories are simulated by using slashes in the object key. "thumbs/file.jpg" is an object key and "thumbs/" would be considered a key prefix.
Dagon's examples are good and use the older version 1.x of the AWS SDK for PHP. However, you can do this more easily with the newest 2.4.x version AWS SDK for PHP which includes a helper method for deleting multiple objects.
<?php
// Include the SDK. This line depends on your installation method.
require 'aws.phar';
use Aws\S3\S3Client;
$s3 = S3Client::factory(array(
'key' => 'your-aws-access-key',
'secret' => 'your-aws-secret-key',
));
// Delete the objects in the "photos" bucket with the a prefix of "thumbs/"
$s3->deleteMatchingObjects('photos', 'thumbs/');
//Include s3.php file first in code
if (!class_exists('S3'))
require_once('S3.php');
//AWS access info
if (!defined('awsAccessKey'))
define('awsAccessKey', 'awsAccessKey');
if (!defined('awsSecretKey'))
define('awsSecretKey', 'awsSecretKey');
//instantiate the class
$s3 = new S3(awsAccessKey, awsSecretKey);
if ($s3->deleteObject("bucketname", `filename`)) {
echo 'deleted';
}
else
{
echo 'no file found';
}
found some code snippets for 'directory' deletion - i did not write them:
PHP 5.3+:
$s3 = new AmazonS3();
$bucket = 'your-bucket';
$folder = 'folder/sub-folder/';
$s3->get_object_list($bucket, array(
'prefix' => $folder
))->each(function($node, $i, $s3) {
$s3->batch()->delete_object($bucket, $node);
}, array($s3));
$responses = $s3->batch()->send();
var_dump($responses->areOK());
Older PHP 5.2.x:
$s3 = new AmazonS3();
$bucket = 'your-bucket';
$folder = 'folder/sub-folder/';
$s3->get_object_list($bucket, array(
'prefix' => $folder
))->each('construct_batch_delete', array($s3));
function construct_batch_delete($node, $i, &$s3)
{
$s3->batch()->delete_object($bucket, $node);
}
$responses = $s3->batch()->send();
var_dump($responses->areOK());
I have implemented this in Yii as,
$aws = Yii::$app->awssdk->getAwsSdk();
$s3 = $aws->createS3();
$s3->deleteMatchingObjects('Bucket Name','object key');
