Получение 400 Bad Request при вызове RestAPI в eclipse, но работа в Postman

Question

У меня есть функция, которая принимает2вход -

1. Путь к файлу
2. RestURL

После вызова функции она должна вернуть вывод какJSON.

Но проблема здесь, это бросание400Ошибка неверного запроса. Ниже приведен журнал ошибок, которые я получаю:

Answer 1

проблема решена. Я только что удалилUTF-8изsetRequestPropertyсоединения, и теперь оно работает.

До :

      con.setRequestProperty("Content-Type", "application/json; UTF-8");

После :

      con.setRequestProperty("Content-Type", "application/json");
