Good night.

I’m doing a job for college that involves logging in..

I’m using the post to pull the requisitions and is giving me the following error:

<br />
<b>Notice</b>: Trying to get property 'senha' of non-object in
<b>C:\wamp64\www\programacao-internet-2\biblioteca_\UsuarioController.php</b> on line <b>28</b><br />

Post type, the url: localhost:8080/api/login and in the body:

{
    "email":"[email protected]",
    "senha": 5667
}

My Usuariocontroller.php file looks like this:

public function autenticar($request, $response, $args){
            $body = $request->getParsedBody();

            $dao = new UsuarioDAO;

            $usuario = $dao->buscarPorEmail($body['email']);
            if($usuario->senha == $body['senha']){
                $token = array(
                    'user' => strval($usuario->id),
                    'nome' => $usuario->nome
                );

                $jwt = JWT::encode($token, $this->key);
                return $response->withJson(['token' =>$jwt, 201])
                                ->withHeader('Content-Type', 'application/json');
            }else{
                return $response->withStatus(401);
            }
        }

Can someone help me? Thanks in advance!

  • This error means that you are trying to access an attribute of a variable that is not an object. From the looks of it, the error is in the "searchPorEmail()" function, because that’s where you’re trying to extract attributes from an object.

I believe the problem lies in your DAO.

The error must be in $usuario->senha, probably your method buscarPorEmail() is not returning an object but an array of objects.

Check in your file User if the method buscarPorEmail() is using fetch(PDO::FETCH_OBJ) instead of fetchAll(PDO::FETCH_OBJ), if it is fetchAll, even if only one result, the return will be an array, then you would change if($usuario->senha == $body['senha']){ for if($usuario[0]->senha == $body['senha']){

  • My searchPorEmail function, ta so: public Function searchPorEmail($email){ $selectEmail = 'SELECT * FROM clients WHERE email=:email'; $Pdo = Connection:::getConnected(); $c = $Pdo->prepare($selectEmail); $c->bindParam ('email', $email); $c->execute(); $c->setFetchMode(PDO::FETCH_ASSOC|PDO::FETCH_PROPS_LATE); $obj = $c->fetch(); Return $obj; }

  • Swap lines: $c->setFetchMode(PDO::FETCH_ASSOC|PDO::FETCH_PROPS_LATE); e $obj = $c->fetch(); By: $c->fetch(PDO::FETCH_OBJ);
