我正在为一个安卓应用程序开发 Facebook 分数 API。我通过访问用户图来查询用户分数:
https://graph.facebook.com/user_id/scores&access_token={user_access_token}
我收到如下回复:
{
"data": [
{
"user": {
"name": "Michał Szydłowski",
"id": "100001699654797"
},
"score": 1200,
"application": {
"name": "QuizzlePeople",
"namespace": "quizzlepeople",
"id": "176694722487191"
}
},
{
"user": {
"name": "Michał Szydłowski",
"id": "100001699654797"
},
"score": 1,
"application": {
"name": "Friend Smash!",
"namespace": "friendsmashsample",
"id": "480369938658210"
}
},
{
"user": {
"name": "Michał Szydłowski",
"id": "100001699654797"
},
"score": 0,
"application": {
"name": "Wordox",
"namespace": "wordox-the-game",
"id": "227993680602156"
}
},
{
"user": {
"name": "Michał Szydłowski",
"id": "100001699654797"
},
"score": 0,
"application": {
"name": "SongPop",
"namespace": "songpop",
"id": "323595464361460"
}
}
]
}
我如何从中提取有用的数据?
我正在尝试将某些东西作为 JSONObject,使用:
HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet("https://graph.facebook.com/me?fields=score&access_token=" + token);
HttpResponse resp = client.execute(get);
Log.i("info1", resp.toString());
// Parse the response
HttpEntity responseEntity = resp.getEntity();
String response = EntityUtils.toString(responseEntity);
Log.i("info1", response);
JSONObject result = new JSONObject(response);
JSONArray arr = result.getJSONArray("data");
Log.i("info2", arr.toString());
只是想看看我能不能拿走任何东西,比如名为“数据”的数组。然而,logcat 并没有显示任何东西。它显示前 2 个日志,但不显示第 3 个。有任何想法吗?
