Slim v4 - Can't get body from PUT requests-CodePudding

I'm trying to do a PUT request with a Slim route.

I'have no problem doing it with a POST request, but when i try to do it with PUT, the variable $body (in the example below) results "NULL". Also by the variable $args['id'] i can get the parameter "id" from the url.

    $app->put('/networks/{id}', function ($request,$response,$args) {
        $body = $request->getParsedBody();
        var_dump($body,1); 
        die();
        [...]
    });

The request headers

This is an example request body sended with header "x-www-form-urlencoded":

name=test&streets[1]=A01,A02,A03&streets[2]=A01,A02,A03

...i prettyed it for readability:

{
    "name": "test",
    "streets[1]": "A01,A02,A03",
    "streets[2]": "A01,A02,A03"
}

Thanks for support C:

I solved by putting

$app->addBodyParsingMiddleware();

I don't know why it works and how it really changes.
