无法解析来自服务器的JSON数据

时间：2012-02-29 05:45:40

标签： java jquery json datatables

我收到“DataTables警告：无法解析来自服务器的JSON数据。这是由JSON格式错误引起的” 我知道这可能是其他线程的重复，我在我的代码中使用java和dataTables。我以JSON格式获取输出但在打印时无法在客户端识别。

当我在http://jsonlint.com/中验证JSON对象时，其格式正确。我不确定是什么导致了这个错误。

  

{ “iTotalRecords”：5 “sEcho”： “1”， “aaData”：[[ “V2993ASFKH230943”， “本田”， “协议”]，[ “V2993A39SNF30943”， “本田”， “CRV”] ，[ “V4833A39SNF30943”， “极品”， “TSX”]，[ “V4833RE9SNF30943”， “极品”， “TL”]，[ “V9383RE9SNF30943”， “极品”， “MDX”]] “iTotalDisplayRecords”：5}

任何帮助都会非常感激。

try {
            JSONObject jsonResponse = new JSONObject();

            jsonResponse.put("sEcho", sEcho);
            jsonResponse.put("iTotalRecords", iTotalRecords);
            jsonResponse.put("iTotalDisplayRecords", iTotalDisplayRecords);

            while (itr.hasNext()) {
                Map rs = (Map) itr.next();
                FleetEquipment eqpmt = new FleetEquipment();
                eqpmt.setVinNumber((String) rs.get("VIN_ID"));
                eqpmt.setMake((String) rs.get("MAKE"));
                eqpmt.setModel((String) rs.get("MODEL"));
                JSONArray row = new JSONArray();
                row.put(eqpmt.getVinNumber()).put(eqpmt.getMake())
                        .put(eqpmt.getModel());
                data.put(row);

            }

            jsonResponse.put("aaData", data);

            response.setContentType("application/json");
            response.getWriter().print(jsonResponse.toString());
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            response.setContentType("text/html");
            response.getWriter().print(e.getMessage());
        }

此工具确实有助于理解外部JSON对象的结构。这可能不是你的问题的答案，但是，这有助于我理解和解析它与python代码，它也是一个JSON验证器。
