从webservice获取JSON

Question

我想在Android代码中创建此字符串。我想从我的webservice获取当前和存储的lat日志。

{"request": 
    {
        "from": "$UDID",
        "with": 
        {
            "action": "GET_DETAILSTORE",
            "device": 
            {
                "id": "$UDID",      
                "time": "1234567890"
            },
            "data":
            {
                "cat_id":"1",
                "more":"10",
                "currentLat":"23.0333",
                "currentLong":"72.6167"
            }
        }
    }
}

您可以从上面的字符串中获取数据，如下所示：

String strResponse = "YOUR_ABOVE_STRING";
JSONTokener tokener = new JSONTokener(strResponse);
JSONObject finalResult = new JSONObject(tokener);

JSONObject objRequest = finalResult.getJSONObject("request");

Log.i("from",objRequest.getJSONString("from"));

JSONObject objWith = objRequest.getJSONObject("with");

Log.i("action",objWith.getJSONString("action"));

JSONObject objDevice = objWith.getJSONObject("device");

Log.i("id",objDevice.getJSONString("id"));
Log.i("time",objDevice.getJSONString("time"));

JSONObject objData = objWith.getJSONObject("data");

Log.i("cat_id",objData.getJSONString("cat_id"));
Log.i("more",objData.getJSONString("more"));
Log.i("currentLat",objData.getJSONString("currentLat"));
Log.i("currentLong",objData.getJSONString("currentLong"));

现在您可以使用来自Web服务的json格式的字符串中的任何数据。

希望它会对你有所帮助。
