Laravel 5.4用户Null使用React Fetch

Question

Route (web.php)

Route::get('user', function () {
    $user=Auth::user();
    return response(['user_id'=>$user->id],200);
});

React.js fetch()

fetch('/user')
            .then(response => {
                return response.json();
            })
            .then(json => {
                console.log(json);
            });

When visiting /user in a browser:

{"user_id":1}

When running the fetch() method:

Trying to get property of non-object

This is because $user=Auth::user(); is returning null.

I know this is not a csrf issue because returning static content (such as user_id=>1 ) works fine with the fetch method.

Here are the cookies being sent with the request:

Whats stopping the user session from working? Been messing with this for hours.

Answer 1

Just noticed that my picture shows cookies being returned, not sent.

Changed fetch() code to this and it worked:

    fetch('/user',{
        credentials: 'include' //Includes cookies
    })
        .then(response => {
            return response.json();
        })
        .then(json => {
            console.log(json);
        });
