can't push file to s3 buket in php - php

Question

I took the sample code from the aws documentation, and I always get this error : IncalculablePayloadException
<?php $filepath = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://$_SERVER[HTTP_HOST]";
require 'aws.phar';
use Aws\S3\S3Client;
use Aws\S3\Exception\S3Exception;
$s3Key = 'mykey';
$s3Secret = 'mysecretkey';
$region = 'eu-west-3';
$s3Bucket = 'mybucket';
$bucket = $s3Bucket;
$file_Path = $filepath.'/msk.png';
$key = basename($filepath);
echo $file_Path;
try {
//Create a S3Client
$s3Client = new S3Client([
'profile' => 'default',
'region' => $region,
'version' => '2006-03-01',
// 'debug' => true
]);
$result = $s3Client->putObject([
'Bucket' => $bucket,
'Key' => $key,
'SourceFile' => $file_Path,
]);
} catch (S3Exception $e) {
echo $e->getMessage() . "\n";
}
I have checked that my file exist, the path is correct. I have no idea what to do, this should work, it's from their damned doc.
I have tried with other files, different code found else where but I always get the same error.
Thanks for the help.
EDIT --------- 1
I have change $file_Path to $file_Path = 'msk.png';
And it's now 'working'. It upload a file to S3, but not a png but an xml file. with at the end
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
Any idea why?
EDIT --------- 2
Ok, so now I know why, the permission of the file was not set to read for public access. How can i set the ACL with putObject ?

The AWS PHP SDK Documentation has this description of SourcePath:
The path to a file on disk to use instead of the Body parameter.
But you are not providing a file on disk, you are providing a URL.
You have two options:
Provide the disk location of the path, based on where it is on your server. For instance, using __DIR__ to refer to the directory of the current PHP file, it might be $file_Path = __DIR__ . '/../public/msk.png';
Download the content first, and pass it in as a string to the Body parameter instead of SourcePath, e.g. using $body = file_get_contents($File_Path);
The first option makes more sense if it's a file on your own server, but the second one might be useful if you've simplified the example.
