通过POST请求将JSON数据发送到https服务器

Question

请帮助，也许有人有通过json通过POST请求向服务器发送和接收数据的经验？

通过传递需要传递参数（方法，id，参数）的json数据来获取编程接口（API），并获取会话ID（结果）。

使用库：com.thetransactioncompany.jsonrpc2

问题是，在提交数据的阶段（respIn = JSONRPC2Session.send（reqOut），请求因500错误而下降，但服务器可用，它似乎不明白这是一个发布请求，我的错误是什么？

NetworkException：

Android

这是我的代码＆＃34; main＆＃34;

java.io.IOException: Server returned HTTP response code: 500 for URL: https://online.sbis.ru/auth/service/
