Кто-нибудь может сказать, почему $ auth_url становится пустым в этом коде?
Мой код приведен ниже: я пытаюсь использовать этот код для импорта контактов Yahoo, в которых я указал app_id, URL-адрес обратного вызова, идентификатор клиента и секрет клиента. Я не понимаю, почему ссылка создает всплывающие окна с тем же URL-адресом. Может быть, это из-за $ auth_url, кто-нибудь может помочь, что я пропускаю?

Решение
Вы никогда не меняли стрелку hasSession. Представьте себе: вы проверяете, есть ли у пользователя активный сеанс. Если у вас нет активного сеанса, вы авторизуетесь, используя тот же сервис. Но после этого входа в систему — вы никогда не перепроверяете сессию / или не обновляете стрелку hasSession. Используйте следующий код:
