вызов службы WCF из JQuery возвращает 400 неверных запросов

/ 16 июня 2020

Я пытаюсь позвонить из веб-службы WCF, используя jquery, но это всегда терпит неудачу с неверным запросом 400.

Как служба WCF, так и веб-сайт развернуты на одном сервере с использованием IIS.

ошибка, которую я получаю в консоли при вызове веб-метода WCF:

Не удалось загрузить ресурс: сервер ответил статусом 400 (неверный запрос)

мой файл конфигурации службы WCF:

Есть два решения, Первое решение:

Вы можете удалить "BodyStyle". Если вы используете "BodyStyle", вам необходимо изменить JSON.

Второе решение:

Если вы не хотите удалять "bodystyle", вам необходимо изменить переданный формат JSON следующим образом: 

{
    "sitesMyMethod": [
        "Query=select value,Lat,Lng,elementID from myTable where code = '" + code + "'"
    ]
}
...
