Не удается разрешить службу для типа при попытке активного контроллера

/ 16 апреля 2020

Я следовал руководству по ссылке ниже: https://fullstackmark.com/post/13/jwt-authentication-with-aspnet-core-2-web-api-angular-5-net-core-identity-and-facebook-login

Мне удалось установить CORS и, наконец, я могу использовать метод post, но когда я пытаюсь сохранить значения через Метод Post, я получаю ошибку, показанную ниже. Я могу понять смысл, но я не могу найти, где я неправильно это понял. Ребята, у вас есть опыт с этим?
