Question

I know there are a few posts on this topic, but I just can figure out what I’m doing wrong.
I have to send by post some parameter to a php server that requires a login.

Here is the code:

DefaultHttpClient httpclient = new DefaultHttpClient();
String postUrl = "http://dev.demo.fr/Contacts/areaGet.php";

HttpHost targetHost = new HttpHost("dev.demo.fr", 80, "http");

httpclient.getCredentialsProvider().setCredentials(
    new AuthScope(targetHost.getHostName(), targetHost.getPort()),
    new UsernamePasswordCredentials("*****", "*****"));
HttpPost httppost = new HttpPost(postUrl);
try {
    // Add your data
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(4);
    nameValuePairs.add(new BasicNameValuePair("language_id", "1"));
    nameValuePairs.add(new BasicNameValuePair("country_id", "1"));
    nameValuePairs.add(new BasicNameValuePair("postal_code", "42830"));
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

    // Execute HTTP Post Request
    response = httpclient.execute(targetHost, httppost);
} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
} catch (IOException e) {
    // TODO Auto-generated catch block
}

System.out.println(response);

IMPORTANT: The username and password are uncoded in here:

httpclient.getCredentialsProvider().setCredentials(
    new AuthScope(targetHost.getHostName(), targetHost.getPort()),
    new UsernamePasswordCredentials("*****", "*****"));

The problem is that when I do this: System.out.println(response); it prints out null and I just don’t know why!!!!

Thank you for your answers!!!

Answer 1

if you get response “null” from server it means your request is not successfully posted on server.
