我想将来自我网站的json数据解码到应用程序。 该应用程序是使用phonegap构建的。 该消息通过GCM进入应用程序,但显示“未定义”。 我不知道解码消息。
这是js中的函数:
function onNotification(e)
{
case 'message':
if (e.foreground)
{
$("#app-status-ul").append('<li>--INLINE NOTIFICATION--' + '</li>');
}
else
{
if (e.coldstart)
$("#app-status-ul").append('<li>--COLDSTART NOTIFICATION--' + '</li>');
else
$("#app-status-ul").append('<li>--BACKGROUND NOTIFICATION--' + '</li>');
}
$("#app-status-ul").append('<li>MESSAGE -> MSG: ' + e.payload.message + '</li>');
//android only
$("#app-status-ul").append('<li>MESSAGE -> MSGCNT: ' + e.payload.msgcnt + '</li>');
//amazon-fireos only
$("#app-status-ul").append('<li>MESSAGE -> TIMESTAMP: ' + e.payload.timeStamp + '</li>');
break;
case 'error':
$("#app-status-ul").append('<li>ERROR -> MSG:' + e.msg + '</li>');
break;
default:
$("#app-status-ul").append('<li>EVENT -> Unknown, an event was received and we do not know what it is</li>');
break;
}
}
这里e.payload.message是要解码并存储到SQLite数据库中的项目。
当我使用stringify时,我得到了解码的数据。这是解码数据
这是我得到的回应。
MESSAGE -> MSG DECODED: {"payload":{"0":{"medicine_name":null},"1":{"tm_1":null},"2":{"tm_2":null},"3":{"tm_3":null},"4":{"dosage":null},"5":{"medicine_name":null},"6":{"tm_1":null},"7":{"tm_2":null},"8":{"tm_3":null},"9":{"dosage":null},"10":{"medicine_name":null},"11":{"tm_1":null},"12":{"tm_2":null},"13":{"tm_3":null},"14":{"dosage":null},"15":{"medicine_name":null},"16":{"tm_1":null},"17":{"tm_2":null},"18":{"tm_3":null},"19":{"dosage":null},"20":{"medicine_name":null},"21":{"tm_1":null},"22":{"tm_2":null},"23":{"tm_3":null},"24":{"dosage":null},"25":{"medicine_name":null},"26":{"tm_1":null},"27":{"tm_2":null},"28":{"tm_3":null},"29":{"dosage":null},"30":{"medicine_name":null},"31":{"tm_1":null},"32":{"tm_2":null},"33":{"tm_3":null},"34":{"dosage":null},"35":{"diagnosis":null},"36":{"instructions":null}}
现在我想知道如何使用sqlite将其存储在db中。?
谢谢。

以下可以在所有JavaScript应用程序中使用,甚至是Ionic / PhoneGap / Cordova。
考虑以下JSON:
[
{
"message":"How is it going",
"fromUser":"akbaralam",
"dateAdded":"Tue May 02 2017"
},
{
"message":"It is been so long that you saw me",
"fromUser":"akbaralam",
"dateAdded":"Tue May 02 2017"
}
]
当使用 JSON.stringify 将此JSON转换为字符串时,我们得到:
"[{"message":"How is it going","fromUser":"akbaralam","dateAdded":"Tue May 02 2017"},{"message":"It is been so long that you saw me","fromUser":"akbaralam","dateAdded":"Tue May 02 2017"}]"
从字符串中获取对象我们执行 JSON.parse(yourStringifiedJson),我们将返回JSON对象。
希望这会有所帮助。
