Access Flask's request in decorator (Python)

Question

I'm wrtiting my first rest api in python (using Flask). I want to create decorator that during every request check if json (request.get_json()) contains for example key "token" and I can get it from this json.

def token_required(func):
    @wraps(func)
    def decorated_view(*args, **kwargs):
        if <token> != "123":
            raise TokenError
        return func(*args, **kwargs)

    return decorated_view

This is my token_required decorator. I don't know how I access request from Flask.

This is my example route:

@blueprint.route('/data/import', methods=['POST', 'OPTIONS'])
@token_required
def import_data_route():
    try:
        return json.loads(json.dumps({"Success": get_session_request(request).add_data(json.loads(request.form['Data']))}))
    except:
        raise ImportDataError
