第一次我這樣做,所以需要幫助。我有一個json文件 https://api.github.com/gists/public 我想在其用戶標籤下取得它的數據只有「login」和「id」。請幫助。json的數據提取
看看這些例子,我嘗試從下面的代碼中獲取數據並將內容放入日誌中,但日誌內容和url中的內容不同。
try {
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet();
request.setURI(new URI("https://api.github.com/gists/public"));
HttpResponse response = client.execute(request);
InputStream ips = response.getEntity().getContent();
BufferedReader buf = new BufferedReader(new InputStreamReader(ips,
"UTF-8"));
StringBuilder sb = new StringBuilder();
String s;
while (true) {
s = buf.readLine();
if (s == null || s.length() == 0)
break;
sb.append(s);
JSONArray ja = new JSONArray(s);
for (int i = 0; i < ja.length(); i++) {
JSONObject jo = (JSONObject) ja.get(i);
//items.add(jo.getString("text"));
Log.v("json", "json object : " + jo.getString("user"));
}
Log.v("json", "json file : " + sb);
}
buf.close();
ips.close();
} catch (URISyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
// any cleanup code...
}
也放置您的JSON ARRAY在這裏,將更清楚如何解決它 –
