WCF restful приложения PUT, POST, DELETE получают ту же ошибку: «метод не разрешен».

0 голосов

Я создаю сервер, реализованный на WCF с архитектурой RESTFUL. Написано в C # с использованием Entity Framework и MySQL DB. Код приведен ниже. VS не выдает никаких ошибок, метод GET работает нормально, он выводит данные из базы данных. Однако все другие методы (PUT, POST, DELETE, GetDetails) получают ту же ошибку: «метод не разрешен». Может быть, вы могли бы сказать, в чем моя ошибка? Если несколько ошибок, то буду благодарен. Я только начал изучать это, поэтому я допускаю, что может быть много ошибок.

Вы должны знать, что запрос по умолчанию, отправляемый браузером, использует Get HTTP-глагол, в то время как операционный контракт требует DELETE HTTP-глагол.
Нажмите F12, Сеть, чтобы просмотреть детали запроса.
enter image description here
Правильный способ проверки запроса POST/DELETE/PUT - отправить запрос с помощью программного обеспечения PostMan (или другого инструмента, такого как Fiddler).

Определение функции. 

[OperationContract]
    [WebInvoke(Method ="DELETE",RequestFormat =WebMessageFormat.Json,ResponseFormat =WebMessageFormat.Json)]
    string GetResult(string id);

Запрос в Fiddler.

Если параметр является составным типом, следует обратить внимание на формат данных запроса.
Подробнее см. По ссылке ниже.
Как вызвать службу RestFul WCF POST для Custom Object с использованием POSTMAN или любого клиентского приложения?
