Rest-我的get方法不返回任何内容

Question

Im new using slim framework and Im trying to make a get. It doesn't return anything and it returns a code 200.

$app->get('/noticias',function ()use ($db,$app){
    try{
        $consulta = $db->prepare("select * from noticias");
        $consulta->execute();

        $resultados = $consulta->fetchAll(PDO::FETCH_ASSOC);
        echo json_encode($resultados);
    }catch (Exception $ex){
        echo  'We cant show the news';
    }
});

When I make a get this is the result

Do you know some tutorials of slim framework??

Thanks

Answer 1

I'm unclear if you're using Slim version 2 or 3. You should be using version 3.

The documentation has the First Application Walkthrough tutorial that you should go through.
