Get Current User Information

See more Facebook Examples

Demonstrates how to retrieve information about the current Facebook user. This is the most basic thing to get working first (after obtaining an access token). Java

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {

    boolean success = false;

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // This example assumes we previously obtained an access token
    CkOAuth2 oauth2 = new CkOAuth2();
    oauth2.put_AccessToken("FACEBOOK-ACCESS-TOKEN");

    CkRest rest = new CkRest();

    // Connect to Facebook and send the following GET request:

    // GET /v2.7/me HTTP/1.1
    // Host: graph.facebook.com
    boolean bAutoReconnect = true;
    success = rest.Connect("graph.facebook.com",443,true,bAutoReconnect);
    if (success != true) {
        System.out.println(rest.lastErrorText());
        return;
        }

    // Provide the authentication credentials (i.e. the access key)
    rest.SetAuthOAuth2(oauth2);

    String responseJson = rest.fullRequestNoBody("GET","/v2.7/me");
    if (rest.get_LastMethodSuccess() != true) {
        System.out.println(rest.lastErrorText());
        return;
        }

    System.out.println(responseJson);

    // The responseJson looks like this:
    // {"name":"John Doe","id":"10111011320111110"}
  }
