Question

我有一个请求和回应Json。当我提交请求时，它将在我的应用程序中显示响应。 Url显示邮递员请求和响应[1]：https://i.stack.imgur.com/UW4jo.png我尝试了下面的代码，但问题是我得到了正确的JSONObject响应但是在调试时光标进入onResponse方法的改造然后body显示null和500错误代码。但在邮递员工作一切都很好。我有这个问题丢了2天。请帮助我。

APIService

@Headers("Content-Type: application/json")
@POST("api/Conveyance/SubmitConveyanceRequest")
Call<List<ModelFileInsertID>> saveTravelRequestDetails(@Body JSONObject submitRequest);

调用api

    JSONObject jsonObject = new JSONObject();
    try {
        jsonObject.put(AppConstants.SaveKeyData.KEY_REIMBURSEMENT_HDR_ID, "");

Answer 1

尝试将JSONObject作为RequestBody传递

RequestBody requestBody = RequestBody.create(MediaType.parse("application/json; charset=utf-8"), jsonObject);
Call<List<ModelFileInsertID>> call = HDFCService.setSaveTravelRequestDetails().saveTravelRequestDetails(requestBody);

API服务接口：

@POST("api/Conveyance/SubmitConveyanceRequest")
Call<List<ModelFileInsertID>> saveTravelRequestDetails(@Body RequestBody body);

OnResponse正文为null并返回500错误代码
