Ruby может импортировать.NET dll?

Я знаю, что эта ветка довольно старая, но у меня была эта проблема, и я придумал классное решение, которое может быть очень полезным для многих, потому что оно исправляет / расширяет библиотеку Volley по многим аспектам.

Я заметил некоторые неработающие функции Volley:

• Этот JSONObjectRequest не идеален: в конце вы должны ожидать JSON (см. Response.Listener<JSONObject> ).
• Как насчет пустых ответов (только с статусом 200)?
• Что мне делать, если я хочу непосредственно мой POJO из ResponseListener?

Я более или менее скомпилировал множество решений в большом родовом классе, чтобы иметь решение для всей проблемы, которую я цитировал.

Это может показаться немного излишним, но это довольно классно иметь все эти конструкторы, потому что у вас есть все случаи:

(Основной конструктор не предназначался для непосредственного использования, хотя это, конечно, возможно).

1. Запрос с ответом, обработанным POJO / заголовками вручную / POJO для отправки
2. Запрос с ответом, обработанным POJO / POJO для отправки
3. Запрос с ответом, обработанным POJO / String для отправки
4. Запрос с ответом, обработанным POJO (GET)
5. Запрос с ответом, обработанным POJO ( GET) / Заголовки вручную установлены
6. Запрос без ответа (200 - Пустое тело) / Заголовки вручную установлены / POJO для отправки
7. Запрос без ответа (200 - Пустое тело) / POJO Отправить
8. Запрос без ответа (200 - Пустое тело) / String to Send

Конечно, для того, чтобы это сработало, у вас должен быть Google GSON Lib ; просто добавьте:

compile 'com.google.code.gson:gson:x.y.z'

к вашим зависимостям (текущая версия 2.3.1).
