我正在尝试在服务器端读取Json对象（用户登录并通过Android应用程序），但在创建过程中，我遇到了一些错误..不知道这是什么意思
UserModel uM = new UserModel();
try {
System.out.println("\nTrying to save...");
InputStream inputStream = request.getInputStream();
JsonReader reader = Json.createReader(inputStream); // this is where error occurs
// JsonObject jsonObject = reader.readObject();
// reader.close();
// System.out.println(jsonObject.get("login").toString());
// uM.setLogin(jsonObject.get("login").toString());
// uM.setPassword(jsonObject.get("password").toString());
// System.out.println(uM.toString());
// userDAO.save(uM);
} catch (IOException e) {
e.printStackTrace();
}
服务器日志： @EDIT 我只发布了警告，现在它的完整日志，可能会更有帮助

@EDIT 2
我添加了将我的Json发送到服务器的部分Android活动。我在这里错过了什么吗？
JSONObject newUser = new JSONObject();
try {
newUser.put("login", login.toString());
newUser.put("password", password.toString());
} catch (JSONException e) {
e.printStackTrace();
}
System.out.println("USER DO ZAPISANIA W BAZIE: " + newUser.toString());
JsonObjectRequest urlAccStringRequest = new JsonObjectRequest(Request.Method.POST, urlAcc, newUser, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
System.out.println("Good morning " + login.toString());
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
progressDialog.dismiss();
Toast.makeText(RegisterIndividualActivity.this, "Connection error", Toast.LENGTH_SHORT).show();
}
});
queueAcc.add(urlAccStringRequest);
queueAcc.start();
}
