[Vuejs]-Use axios with Vue and Laravel for post request

There’s no need to add params in URL since it’s POST request. You should use API routes (api.php) in Laravel and could structure it like this

Route::POST('/vote', 'QuestionController@vote');

Since you place it in api.php as API route, it would be prefixed with /api.
So you axios call should look like this:

addVote(id) {
            axios.post(`/api/vote`, {id: id});
}

Now in your vote method of QuestionController would look like this:

public function vote(Request $request)
{
    dd($request);
}

You will see dump of request data and decide what to do with it.
