Authenticated user is null in Laravel API without token

Question

I am trying to save my data against logged in user id. But I am unable to do it. I am testing my api using Postman and using JWT auth. When I am logged in I get a token. I can save data against user_id with that token. But I don't want to pass that token on every request.

What I am trying here is to save user_id like this:

auth()->guard('api')->user();

My whole controller method:

$business = new Business();
$business->business_name = Input::get('business_name');
$business->business_url = Input::get('business_url');
$business->user_id = auth()->guard('api')->user();


$business->save();

$resultArray = ['status' => 1, 
    'message' => 'Business added!', 
    'dataArray' => $business
];

When i go with this error is

Integrity constraint violation: 1048 Column 'user_id' cannot be null

When I log in I get a response like following:

{
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwOi8vMTI3LjAuMC4xOjgwMDAvYXBpL2xvZ2luIiwiaWF0IjoxNTIzOTYxNDEwLCJleHAiOjE1MjM5OTc0MTAsIm5iZiI6MTUyMzk2MTQxMCwianRpIjoiVWppUVVXTENWNjQ4WTJWNyIsInN1YiI6MSwicHJ2IjoiODdlMGFmMWVmOWZkMTU4MTJmZGVjOTcxNTNhMTRlMGIwNDc1NDZhYSJ9.rIjmaEA1HdG64uolyKO9gVX6mqiQ8PN-a2YGO2-Palo",
    "currentUser": {
        "id": 1,
        "name": "Shahzad Hussain",
        "email": "[email protected]",
        "created_at": "2018-04-17 05:55:55",
        "updated_at": "2018-04-17 05:55:55"
    }
}

I need your help and it will be highly appreciated!

Answer 1

change

auth()->guard('api')->user();

to

\Auth::user()->id

or

public function __construct(Guard $auth)
{
        $this->currentUser = $auth->user();
}

$business->user_id = $this->currentUser->id;

or

auth()->user()->id
