Статус 500: InvalidOperationException: ни один маршрут не соответствует предоставленным значениям

Question

Мой webapi работает с get и getById, но у моего поста есть проблемы.Он успешно отправит в базу данных, но возвращенное тело в почтальоне показывает 500 ошибок с маршрутами.Мой поиск в Google до сих пор предлагал добавлять имена к запросам, что я и сделал, но не помогло.Буду признателен за любой совет.

Я пытался добавить имена к запросам, но безуспешно.

В идеале он должен возвращать 200 и показывать добавленную запись при публикации.

Answer 1

Теперь это решено.

Для всех, кто мог бы прочитать это и ответить на этот вопрос, проблема заключалась в том, что мой почтовый запрос возвращался:

return CreatedAtRoute("LocationById", new { id = location.Id }, location);

, и это было неверноимя для запроса GetLocationById.Как только я изменил сообщение, вернемся к:

return CreatedAtRoute("GetLocationById", new { id = location.Id }, location);

, все это работало нормально.

Answer 2

Попробуйте указать маршрут для каждого метода, добавив атрибут [Route("api/location/getlocationbyid/{id}")].Когда вы сделаете это, вам, возможно, придется уменьшить атрибут get до [HttpGet].
