Что не так с этой многочастной формой? Android-Java

Question

Я всегда возвращаюсь Требуется длина контента 411, что я делаю неправильно здесь? я не отправляю его правильно? Я отправляю на сервер RoR. Это в основном будет переключаться между заявлениями в зависимости от погоды есть изображение или нет. Спасибо, парни.

Длина содержимого - это свойство заголовка запроса Http, а не свойство запроса HTTP.

Это не устанавливает Content Length в заголовке запроса HTTP:

feed_connection.setRequestProperty("Content-Length", String.valueOf((session_key.length() + feed.length() + sh_career.length() + sh_friend.length() + url_t.length() + url_d.length() + url_a.length() + topic_id.length() + image_part_1.length() + image_part_2.length() + missing_link.length() + image_part_3.length()))); 

Попробуйте использовать HttpURLConnection.setFixedLengthStreamingMode() установить Content Length, например:

feed_connection.setFixedLengthStreamingMode(session_key.length() + feed.length() + sh_career.length() + sh_friend.length() + url_t.length() + url_d.length() + url_a.length() + topic_id.length() + image_part_1.length() + image_part_2.length() + missing_link.length() + image_part_3.length()); 

Надеется, что это помогает.
