Requête Http get sur Android 2.3.3

J'ai besoin d'aide avec l'envoi de HTTP GET demande. Mon code est comme suit:

    URL connectURL = new URL("url");
    HttpURLConnection conn = (HttpURLConnection)connectURL.openConnection(); 

    conn.setDoInput(true); 
    conn.setDoOutput(true); 
    conn.setUseCaches(false); 
    conn.setRequestMethod("GET"); 

    conn.connect();
    conn.getOutputStream().flush();      
    String response = getResponse(conn);

Mais il ne parvient pas à getResponse(conn); Pourquoi?

D'où vient getResponse viennent (dans quelle classe est-ce code placé) et quelle est l'erreur?

    OBTENIR la demande pourrait être utilisée comme ceci:

    try {
    HttpClient client = new DefaultHttpClient();  
    String getURL = "http://www.google.com";
    HttpGet get = new HttpGet(getURL);
    HttpResponse responseGet = client.execute(get);  
    HttpEntity resEntityGet = responseGet.getEntity();  
    if (resEntityGet != null) {  
        //do something with the response
        String response = EntityUtils.toString(resEntityGet);
        Log.i("GET RESPONSE", response);
    }
} catch (Exception e) {
    e.printStackTrace();
}
    Je veux envoyer des paramètres.Comment faire?
    Vous pouvez ajouter les paramètres comme ceci: "google.com?param1=valeur1&param2=valeur2" Il y a aussi la méthode "POST" de l'envoi de données, dans ce cas, vous n'avez pas besoin d'ajouter des paramètres à l'url généralement ce qui est plus preferablly. diffen.com/difference/Get_vs_Post

    Je crois setDoOutput(true) implique POST automatiquement.

    J'utilise ce bout de code pour OBTENIR la réponse qui fonctionne bien sur ma fin:

    HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(requestUrl);
HttpResponse response=null;
try {
response = client.execute(request);
} catch (ClientProtocolException e) {
Log.d(TAG,"1. "+e.toString());
} catch (IOException e) {
Log.d(TAG,"2. "+e.toString());
}
int status_code=response.getStatusLine().getStatusCode();
Log.d(TAG,"Response Code returned ="+status_code);
BufferedReader in=null;
try {
in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
} catch (IllegalStateException e) {
Log.d(TAG,"3. "+e.toString());
} catch (IOException e) {
Log.d(TAG,"4. "+e.toString());
}
StringBuffer sb = new StringBuffer("");
String line = "";
String newline = System.getProperty("line.separator");
try {
while ((line = in.readLine()) !=null){
sb.append(line + newline);
}
String data = sb.toString();
Log.d(TAG,data);
} catch (IOException e) {
Log.d(TAG,"5. "+e.toString());
}
try {
in.close();
} catch (IOException e) {
Log.d(TAG,"6. "+e.toString());
}
String data = sb.toString();
try {
if(status_code==200 || status_code==401){
JSONObject responseJSONObject = new JSONObject(data);
responseJSONObject.put("tpg_status_code", status_code);
}
} catch (JSONException e) {
Log.d(TAG,"6. "+e.toString());
}

    - je utiliser ce code et il fonctionne parfaitement:

    public class HttpGetAndroidExample extends Activity {
TextView content;
EditText fname,email,login,pass;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_http_get_android_example);
content   =  (TextView)findViewById(R.id.content);
fname     =  (EditText)findViewById(R.id.name);
email      =  (EditText)findViewById(R.id.email);
login       =  (EditText)findViewById(R.id.loginname);
pass       =  (EditText)findViewById(R.id.password);
Button saveme=(Button)findViewById(R.id.save);
saveme.setOnClickListener(new Button.OnClickListener(){
public void onClick(View v)
{ 
//ALERT MESSAGE
Toast.makeText(getBaseContext(),"Please wait, connecting to server.",Toast.LENGTH_LONG).show();
try{ 
//URLEncode user defined data
String loginValue    = URLEncoder.encode(login.getText().toString(), "UTF-8");
String fnameValue  = URLEncoder.encode(fname.getText().toString(), "UTF-8");
String emailValue   = URLEncoder.encode(email.getText().toString(), "UTF-8");
String passValue    = URLEncoder.encode(pass.getText().toString(), "UTF-8");
//Create http cliient object to send request to server
HttpClient Client = new DefaultHttpClient();
//Create URL string
String URL = "http://androidexample.com/media/webservice/httpget.php?user="+loginValue+"&name="+fnameValue+"&email="+emailValue+"&pass="+passValue;
//Log.i("httpget", URL);
try
{
String SetServerString = "";
//Create Request to server and get response
HttpGet httpget = new HttpGet(URL);
ResponseHandler<String> responseHandler = new BasicResponseHandler();
SetServerString = Client.execute(httpget, responseHandler);
//Show response on activity 
content.setText(SetServerString);
}
catch(Exception ex)
{
content.setText("Fail!");
}
}
catch(UnsupportedEncodingException ex)
{
content.setText("Fail");
}     
}
});

    }
    }
