通过改造调用post请求时，收到400个错误请求错误

Question

通过邮递员API正在工作，但相同的API不与改造工作，我收到400个错误的改造要求

返回true或false的endpoint@POST（“/emrmegax/api/allscript/saveappointment”）调用saveappointment（@Header（“x-auth-token”）字符串header1，@Body字符串yy）；

    and this is my method from where i am calling this above API
    private void saveAppoint(String token, Saveappointment mSaveappointment){
    APIInterface service = APIClient.getRetrofitInstance().create(APIInterface.class);
    JSONObject paramObject = new JSONObject();
    paramObject.put("ehrAppointmentId", "");
    paramObject.put("ehrPatientId", mSaveappointment.getEhrPatientId());
    paramObject.put("appointmentType", mSaveappointment.getAppointmentType());
    paramObject.put("ehrProviderAbbrev", mSaveappointment.getEhrProviderAbbrev());
    paramObject.put("ehrProviderId", mSaveappointment.getEhrProviderId());
    paramObject.put("reason", mSaveappointment.getReason());
    paramObject.put("startDateTime", mSaveappointment.getStartDateTime());

    Call<Boolean> call = service.saveAppointment(token, paramObject.toString());
    call.enqueue(new Callback<Boolean>() {
        @Override
        public void onResponse(Call<Boolean> call, Response<Boolean> response) {
            progressDialog.dismiss();
            //boolean value=response.body();
            if (!response.isSuccessful()) {

                Toast.makeText(mcontext, "" + response.code() + " " + response.body(), Toast.LENGTH_SHORT).show();
            }
        }
        @Override
        public void onFailure(Call<Boolean> call, Throwable t) {
          Toast.makeText(mcontext, "" + t.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });
   }

400错误请求错误意味着客户端发出的请求不正确或已损坏，服务器无法理解（解析）它。400错误请求错误的一些原因：

• 无效的url.
• 报头无效/丢失。

也许响应错误正文包含一些详细的消息？
