How can I authenticate Google Cloud Translate from PHP?

I'm trying to use the google/cloud-translate library (v ^1.5) in Laravel (v ^6.0).

In GoogleController.php:

public function translate(Request $request) {
    $request->validate([
        'source' => 'required|string|min:2|max:5',
        'target' => 'required|string|min:2|max:5',
        'q' => 'required|string',
    ]);

    $translate = new TranslateClient([
        'keyFile' => base_path(config('services.google.json_path')),
        'projectId' => config('services.google.project_id'),
        'suppressKeyFileNotice' => true,
    ]);

    // Translate text from english to french.
    $result = $translate->translate($request->q, [
        'target' => explode($request->target, '-')[0],
        'source' => explode($request->source, '-')[0],
    ]);

    return $result;
}

But calling the route in Postman gives me the error:

Argument 2 passed to Google\Auth\CredentialsLoader::makeCredentials() must be of the type array, string given, called in /[...]/vendor/google/cloud-core/src/RequestWrapperTrait.php on line 155

I've checked that the projectId and the path to the keyFile is correct. Can anyone shed some light on how to get past this error?

You're specifying the path to the key file, so you should use the keyFilePath parameter instead.

Try this:

$translate = new TranslateClient([
    'keyFilePath' => base_path(config('services.google.json_path')),
    ...
]);

From the TranslateClient.__construct docs:

  • keyFile: The contents of the service account credentials .json file retrieved from the Google Developer's Console. Ex: json_decode(file_get_contents($path), true).
  • keyFilePath: The full path to your service account credentials .json file retrieved from the Google Developers Console.
