404 Not Found when I try to get the data

[sboal94]

Well, I'm trying to connect to Firebase realtime database from php in the following way:

use Kreait\Firebase\Factory;
require 'vendor/autoload.php';
require 'init/config.php';

$factory = (new Factory)->withServiceAccount(../firebase.json);
$database = $factory->createDatabase();
$reference = $database->getReference('/courses');
$value = $reference->getValue();

I have also tried with

$reference = $database->getReference('courses');
$snapshot = $reference->getSnapshot();
$value = $snapshot->getValue();

And

$database->getReference('courses')->getChildKeys();

And everything gives the same result...
I don't know what I'm doing wrong, if anyone can give me a hand

Firebase rules:

{
  "rules": {
        ".read": true,
        ".write": true,
  }
}

Database:

When I try to do <?php echo $value; ?> the response is:

Fatal error: Uncaught GuzzleHttp\Exception\ClientException: Client error: GET https://myWeb.firebaseio.com/courses resulted in a 404 Not Found response: in /Users/myName/sites/web/vendor/guzzlehttp/guzzle/src/Exception/RequestException.php:113 Stack trace: #0 /Users/myName/sites/web/vendor/guzzlehttp/guzzle/src/Middleware.php(69): GuzzleHttp\Exception\RequestException::create(Object(GuzzleHttp\Psr7\Request), Object(GuzzleHttp\Psr7\Response), NULL, Array, NULL) #1 /Users/myName/sites/web/vendor/guzzlehttp/promises/src/Promise.php(204): GuzzleHttp\Middleware::GuzzleHttp{closure}(Object(GuzzleHttp\Psr7\Response)) #2 /Users/myName/sites/web/vendor/guzzlehttp/promises/src/Promise.php(153): GuzzleHttp\Promise\Promise::callHandler(1, Object(GuzzleHttp\Psr7\Response), NULL) #3 /Users/myName/sites/web/vendor/guzzlehttp/promises/src/TaskQueue.php(48): GuzzleHttp\Promise\Promise::GuzzleHttp\Promise{closure}() #4 /Users/myName/sites/web/vendor/guzzlehttp/promise in /Users/myName/sites/web/vendor/kreait/firebase-php/src/Firebase/Exception/DatabaseApiExceptionConverter.php on line 62

I am working with :
macOs Big Sur 11.0.1
MAMP (same as xampp in windows)
PHP 7.4.12
kreait/firebase-php 5.13.0

Output of composer show | grep kreait:
kreait/clock 1.1.0 A PHP 7.0 compatible clock abstraction
kreait/firebase-php 5.13.0 Firebase Admin SDK
kreait/firebase-tokens 1.14.0 A library to work with Firebase tokens

Thanks a lot!! 👍

Thank you for the detailed description! It was said on the discord server that Firebase has changed the way it names the default Realtime Database name on new projects, and I believe (hope 😅) that this is the case here.

Could you please check on https://console.firebase.google.com/project/_/database/ what the name of your database is? You can find it right of the 🔗 symbol and it should look something like https://<some-string>.firebaseio.com (By default, the SDK will build this URL from the project_id field in your service account JSON file).

Once you have that URL, you can configure it in the SDK with the withDatabaseUri() method of the Factory class, so for example:

$factory = (new Factory)
    ->withServiceAccount(../firebase.json)
    ->withDatabaseUri('https://my-database-name.firebaseio.com');

$database = $factory->createDatabase();

Please let me know if this works 🤞
