我在对服务器的 GET 请求的结果中得到这个响应
{"LL": { "control": "dev/sys/getkey", "value": "4545453030304138303046392035343733373432363020323031332D30322D31312031383A30313A3135", "Code": "200"}}
我只想"value"
从上面的 json 响应中提取值。
我正在使用此代码来获取此响应
findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
HttpResponse response = null;
try {
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet();
request.setURI(new URI(
"http://192.168.14.247/jdev/sys/getkey"));
response = client.execute(request);
} catch (URISyntaxException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String responseText = null;
try {
responseText = EntityUtils.toString(response.getEntity());
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Log.i("Parse Exception", e + "");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Log.i("IO Exception 2", e + "");
}
Log.i("responseText", responseText);
Toast.makeText(MainActivity.this, responseText + "",
Toast.LENGTH_SHORT).show();
}
});
我的问题是我如何解析这个并获取唯一"value"
标签的值。谢谢
