in my app i need to post data to an url to register a new user. Here is the url
http://myurl.com/user.php? email=[EMAIL]&username=[USERNAME]&password[PASS]&img_url=[IMG]
If I do that correctly I should get this message:
{"success":true,"error":null}
or if not {"success":false,"error":"parameters"}
Can somebody guide me through this and tell me how can I do it.
first :
you need to perform all network tasks in an Async thread using:
public class PostData extends AsyncTask<String, Void, String>{
{
@Override
protected String doInBackground(String... params) {
//put all your network code here
}
Second:
create your http request:
i am assuming email, username and IMG as variables over here.
String server ="http://myurl.com/user.php? email=[" + EMAIL + "]&username=[" + USERNAME + "]&password[" + PASS + "]&img_url=["+IMG + "]";
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(server);
//httppost.setHeader("Accept", "application/json");
httppost.setHeader("Accept", "application/x-www-form-urlencoded");
//httppost.setHeader("Content-type", "application/json");
httppost.setHeader("Content-Type", "application/x-www-form-urlencoded");
third:
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("JSONdata", Object));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs,"UTF-8"));
try {
HttpResponse response =httpclient.execute(httppost);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
Now simple query your response handler i.e. response in this case.
Don't forget to add INTERNET permission in your androidManifest.xml
Hope this helps!
Use a HTTP client class, and format your URL via a specific URI constructor. Create a HTTP post, optionally set the entity, headers, etc, execute the post via the client, receive a HTTP response, pull the entity out of the response and process it.
EDIT for example:
HttpClient httpclient = new DefaultHttpClient();
URI uri = new URI("http",
"www.google.com", // connecting to IP
"subpath", // and the "path" of what we want
"a=5&b=6", // query
null); // no fragment
HttpPost httppost = new HttpPost(uri.toASCIIString);
// have a body ?
// post.setEntity(new StringEntity(JSONObj.toString()));
// post.setHeader("Content-type", "application/json");
HttpResponse response = httpClient.execute(post);
int statusCode = response.getStatusLine().getStatusCode();
HttpEntity entity = response.getEntity();
Reader r = new InputStreamReader(entity.getContent());
// Do something with the data in the reader.
