JSONParser类在教程中较低,看起来像这样……

public class JSONParser {

static InputStream is = null;

static JSONObject jObj = null;

static String json = "";

// constructor

public JSONParser() {

}

// function get json from url

// by making HTTP POST or GET method

public JSONObject makeHttpRequest(String url, String method,

List params) {

// Making HTTP request

try {

// check for request method

if(method == "POST"){

// request method is POST

// defaultHttpClient

DefaultHttpClient httpClient = new DefaultHttpClient();

HttpPost httpPost = new HttpPost(url);

httpPost.setEntity(new UrlEncodedFormEntity(params));

HttpResponse httpResponse = httpClient.execute(httpPost);

HttpEntity httpEntity = httpResponse.getEntity();

is = httpEntity.getContent();

}else if(method == "GET"){

// request method is GET

DefaultHttpClient httpClient = new DefaultHttpClient();

String paramString = URLEncodedUtils.format(params, "utf-8");

url += "?" + paramString;

HttpGet httpGet = new HttpGet(url);

HttpResponse httpResponse = httpClient.execute(httpGet);

HttpEntity httpEntity = httpResponse.getEntity();

is = httpEntity.getContent();

}

} catch (UnsupportedEncodingException e) {

e.printStackTrace();

} catch (ClientProtocolException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

try {

BufferedReader reader = new BufferedReader(new InputStreamReader(

is, "iso-8859-1"), 8);

StringBuilder sb = new StringBuilder();

String line = null;

while ((line = reader.readLine()) != null) {

sb.append(line + "\n");

}

is.close();

json = sb.toString();

} catch (Exception e) {

Log.e("Buffer Error", "Error converting result " + e.toString());

}

// try parse the string to a JSON object

try {

jObj = new JSONObject(json);

} catch (JSONException e) {

Log.e("JSON Parser", "Error parsing data " + e.toString());

}

// return JSON String

return jObj;

}

}
