javascript - Upload files to Google Cloud Storage Bucket using PHP
I've searched a lot (and even found some helpful links like this one Upload a file to Google Cloud Storage Bucket with PHP and Ajax) but I couldn't get it working. I need to upload a txt file to my google cloud storage bucket.
Here's my code:
gcp_storage.php:
<?php
if(isset($_FILES['file'])){
$errors= array();
// Authentication with Google Cloud Platform
$client = new StorageClient(['keyFilePath' => 'cloudtest-2412**-a66e94ba56**.json']);
$bucket = $client->bucket('cloudtest-2412**.appspot.com ');
// Upload a file to the bucket.
$file = pathinfo($_FILES['file']['name']);
$prefix = uniqid('prefix_', true); //generate random string to avoid name conflicts
$filename = $prefix . "." . $file['extension'];
$bucket->upload(
fopen($_FILES['file']['tmp_name'], 'r'),
['name' => $filename]
);
}
?>
html and js:
<html>
<form id="fileForm" action="" method="post" enctype="multipart/form-data">
<div >
<br/>
<div >
<label for="textFile">Text File: </label>
<br/>
<input type="file" name="file" id="textFile">
</div>
</div>
<br>
<button type="submit" > Upload </button>
</form>
</html>
<script
src="https://code.jquery.com/jquery-3.4.1.min.js"
integrity="sha256-CSXorXvZcTkaix6Yvo6HppcZGetbYMGWSFlBw8HfCJo="
crossorigin="anonymous"></script>
<script>
$(document).on('submit', '#fileForm', function (e) {
e.preventDefault();
var data = new FormData($('#fileForm').get(0));
$.ajax({
type: 'POST',
url: 'gcp_storage.php',
data: data,
processData: false,
contentType: false,
success: function ($data) {
console.log('Succcess');
$('#success').attr('hidden', false);
}
});
});
</script>
*It shows on my console success but when I go to my bucket on google cloud, nothing appears...
*I downloaded the .json file from the IAM page (the file is in the same directory as the other filse)
EDIT 1:
Don't know if this really helps, if I remove theuse Google\Cloud\Storage\StorageClient, PHP throws me the errorClass 'StorageClient' not found in /base/data/home/apps/i (when I put back the use code it just throws the 500 error, see below)
I've been changing the code and putting breakpoints to see if I find where the 500 error is coming from. If I remove everything from my PHP file and just putecho "Test", it works fine.
After putting some breakpoints at the original code, I found out that the 500 error comes from this lines of code:
$client = new StorageClient(['keyFilePath' => 'cloudtest-2412**-a66e94ba56**.json']);
$bucket = $client->bucket('cloudtest-2412**.appspot.com');
(The authentication code)
Any suggestions?
Thanks

Solution:
I think, we can see a permission error. In most cases, an internal 500 server error is due to incorrect permission in one or more files or folders.
