I solve my issue and I'm going to share it in case someone needs it. So the way I was getting the JsonObjec was by doing this in Routes.php:
我解决了我的问题，如果有人需要，我会分享它。所以我获得 JsonObjec 的方法是在 Routes.php 中这样做：
Route::post('/register', function(){
if(Request::ajax()){
Log::info('From Ajax: ' . print_r(Response::json(Request::all()), true));
return var_dump(Response::json(Request::all()));
}
});
But instead I did this to actually access the value of user (Tom).
但是我这样做是为了实际访问用户（Tom）的值。
$somevar = (Request::all());
Log::info('From Ajax: ' . print_r($somevar["user"], true));
This solve my issue. Hope it helps anyone out there!
这解决了我的问题。希望它可以帮助那里的任何人！

With Laravel you can access to JSON data same way as regular variables. In your case you need something like:
使用 Laravel，您可以像访问常规变量一样访问 JSON 数据。在您的情况下，您需要类似的东西：
$username = $request->get('user');
