我想将 json 发送到我的 API 并接收 Json 形式的响应，但它显示 400 错误请求
i want to send json to my API and recive the Json form of response but it show 400 bad request
我和使用 google protobuffer 形成我的 json 并作为 post 调用发送到服务器但它会 return 我 400 Bad Request 但同时json 我会发送给邮递员，它会 return 给我有效的回复，但在 android 中，它不会给我发送有效的回复，我不知道实际发生了什么

这是我用来发送和接收的代码 Json 但 id 会向我发送 400 BAD REQUEST
postman截图，会return200
请为我提供一些解决方案或发送一些库，以便我使用它们来调用 http 请求或使用 json
