You can also set the Content-Type header in the request if it is missing using middleware:

$app->post('/test', function($request, $response, $args) {
    $body = $request->getParsedBody();
    // ...
})->add(function($request, $response, $next) {
    // set application/json as content-type if no content type is set
    if (!$request->hasHeader('Content-Type')) {
        $request = $request->withHeader('Content-Type', 'application/json');
    }

    return $next($request, $response);
});
