Question

Here is my code to send the data from android app to php app which is running in my localhost. It is showing “Connection to http:// localhost refused” . Please help me

public void postData() throws JSONException
{

    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();

    HttpPost httppost = new HttpPost("http://localhost/xampp/FeelSafeSecurity/connectiondemo.php");

    JSONObject json = new JSONObject();

    try {
        // prepare JSON data:
        json.put("name", "santhosh");
        json.put("age", "24");

        JSONArray postjson=new JSONArray();
        postjson.put(json);

        // Post the data:
        httppost.setHeader("json", json.toString());
        httppost.getParams().setParameter("jsonpost",postjson);

        // Execute HTTP Post Request
        System.out.print(json);
        HttpResponse response = httpclient.execute(httppost);

        // for JSON:
        if(response != null)
        {
            InputStream is = response.getEntity().getContent();

            BufferedReader reader = new BufferedReader(new InputStreamReader(is));
            StringBuilder sb = new StringBuilder();

            String line = null;
            try {
                while ((line = reader.readLine()) != null) {
                    sb.append(line + "\n");
                }
            } catch (IOException e) {
                e.printStackTrace();
            } finally {
                try {
                    is.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            text = sb.toString();
        }

        tv.setText(text);

    }
    catch (ClientProtocolException e)
    {
        System.out.println(e.getMessage()); 
         e.printStackTrace();
    } catch (IOException e) {
         e.printStackTrace(); 
    }
}

And here is my php code to receive the data. I’am new to PHP.

<?php
$json = $_SERVER['HTTP_JSON'];
echo "JSON: \n";
echo "--------------\n";
var_dump($json);
echo "\n\n";

$data = json_decode($json);
echo "Array: \n";
echo "--------------\n"; 
var_dump($data); 
echo "\n\n";

echo "Result: \n";
echo "--------------\n";
echo "\n\nName     : ".$data->name."\n\n Age : ".$data->age;
?>

Don’t use localhost use your IP address. Localhost is only for the LOCAL server
