Class 'App\Http\Controllers\DownstreamResponse' not found about laravel-fcm HOT 8 CLOSED

Hi
I think it Missing an import of Laravel-FCM\Response\DownstreamResponse somewhere in the code.

Can you give me more informations about this error.
Maybe with a part of your code that thrown the exception.

Thanks

from laravel-fcm.

$downstreamResponse = FCM::sendTo($tokens, $option, $notification);

$downstreamResponse->numberSuccess();
$downstreamResponse->numberFailure();
$downstreamResponse->numberModification();

//return Array - you must remove all this tokens in your database
$downstreamResponse->tokensToDelete();

//return Array (key : oldToken, value : new token - you must change the token in your database )
$downstreamResponse->tokensToModify();

//return Array - you should try to resend the message to the tokens in the array
$downstreamResponse->tokensToRetry();

// return Array (key:token, value:errror) - in production you should remove from your database the tokens present in this array
$downstreamResponse->tokensWithError();

I commented out those lines apart from the first one and it worked.

I am unable to reproduce your problem

Do you use Laravel or Lumen?
Can you give me all the content of the error message?

This is related to not having the use statement for LaravelFCM\Response\DownstreamResponse (as you said, not imported).

The readme is missing them in some of the other examples, I only updated one.

from laravel-fcm.

I am using Laravel 5.2

Notifications are sent but it produce errors on my laravel.log and I found these lines of codes are the ones causing it:

        $downstreamResponse = new DownstreamResponse($response, $tokens);
        $downstreamResponse->numberSuccess();
        $downstreamResponse->numberFailure();
        $downstreamResponse->numberModification();

        //return Array - you must remove all this tokens in your database
        $downstreamResponse->tokensToDelete(); 

        //return Array (key : oldToken, value : new token - you must change the token in your database )
        $downstreamResponse->tokensToModify(); 

        //return Array - you should try to resend the message to the tokens in the array
        $downstreamResponse->tokensToRetry();

This was the error:

[2016-07-22 09:10:28] local.ERROR: exception 'Symfony\Component\Debug\Exception\FatalErrorException' with message 'Class 'App\Api\V1\Controllers\DownstreamResponse' not found' in C:\wamp\www\MyApp\app\Api\V1\Controllers\PushNotificationController.php:42

After I did what @gcphost recommended (use LaravelFCM\Response\DownstreamResponse;), I got the following error:

[2016-07-22 09:11:39] local.ERROR: exception 'ErrorException' with message 'Undefined variable: response' in C:\wamp\www\MyApp\app\Api\V1\Controllers\PushNotificationController.php:42

Sorry, what does those lines of code do, I mean what are their functions.

Hi,

I think that your error is thrown by the following line:

$downstreamResponse = new DownstreamResponse($response, $tokens); 

You shouldn't instantiate DownstreamReponse in your controller.

DownstreamResponse is constructed by the package and is returned by the method: FCM::sendTo($tokens, $option, $notification);

Like in the following line:

$downstreamResponse = FCM::sendTo($tokens, $option, $notification);

In summary,

1. You send a notification with the method FCM::sendTo($tokens, $option, $notification);.
2. The package is sending the notification and constructs a DownstreamResponse with the response returned by fcm.
3. In your controller, you can check if the notification was send with success or if some error appeared during the process, with the following methods:
   $downstreamResponse->numberSuccess(), $downstreamResponse->numberFailure(); and $downstreamResponse->numberModification();
4. You can get all tokens that you must to remove in your database with the method: $downstreamResponse->tokensToDelete();
5. You can get all tokens that you must to modify in your database with the method: $downstreamResponse->tokensToModify();
6. You can all tokens that you should resend with this method: $downstreamResponse->tokensToRetry();

Please can you give me a feedback if this solution is working for you.

Best Regards
