问题描述
我努力的JSON解析，但是当解析则给出错误
httppost方法不受此URL支持
我在这里放下我的code

解决方案
You should use Get request instead of POST request.
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//make async request
new myAsynctask().execute();
}
//********************************************
//get json string
public String getJSONString() {
StringBuilder builder = new StringBuilder();
HttpClient client = new DefaultHttpClient();
String urlString="http://www.ajax.googleapis.com/ajax/services/search/local?v=1.0&q=restaurants&rsz=8&sll=-27.5595451,-48.6206452&radius=1000&output=json";
HttpGet httpGet = new HttpGet(urlString);
try {
HttpResponse response = client.execute(httpGet);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) {
HttpEntity entity = response.getEntity();
InputStream content = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(content));
String line;
while ((line = reader.readLine()) != null) {
builder.append(line);
}
} else {
Log.e(getClass().getSimpleName(), "Failed to download json response");
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return builder.toString();
}
//********************************************
private class myAsynctask extends AsyncTask<Void, Void, String>{
@Override
protected String doInBackground(Void... params) {
String jsonString=getJSONString();
return jsonString;
}
@Override
protected void onPostExecute(String jsonString) {
super.onPostExecute(jsonString);
Log.e(getClass().getSimpleName(), jsonString);
}
}
}
