Hello,

I'm pretty new in the Android World and I just finished a website (http://drupal.org/node/777420).

I would like to make an android app out of it.

I've read alot and I'm using the 'Services' module with XMLRPC.

I'm struggling to do a user authentication and I don't understand the 7 arguments it needs.

Here is the Android Java code I'm using:

                final XMLRPCMethod method1 = new XMLRPCMethod("user.login", new XMLRPCMethodCallback() {
                    public void callFinished(Object result) {
                        testResult.setText(result.toString());
                        // returns:  result={user={uid=0, cache=0, hostname=81.243.167.37, session=, roles={1=anonymous user}}, sessid=4da293fe9394029b4e465b01d81c5fd5}
                    }
                });
                XMLRPCMethod method2 = new XMLRPCMethod("system.connect", new XMLRPCMethodCallback() {
                    public void callFinished(Object result) {
                        GlobalDataStore.sessid = (String) ((Map) result).get("sessid");
                        Object[] params = {
                             GlobalDataStore.sessid,GlobalDataStore.user,GlobalDataStore.password
                        };
                        method1.call(params);
                    }
                });
                method2.call();

The error here is:

D/Test    (  488): org.xmlrpc.android.XMLRPCFault: XMLRPC Fault: Missing required arguments. [code 1]

I've looked into documentation and I see that the method user.login needs 7 arguments:

  • string hash (required) : A valid API key.
  • string domain_name (required) : A valid domain for the API key.
  • string domain_time_stamp (required) : Time stamp used to hash key.
  • string nonce (required) : One time use nonce also used hash key.
  • string sessid (required) : A valid sessid.
  • string username (required) : A valid username.
  • string password (required) : A valid password.

I have the last 3 (sessid, username and password), how, where to get the others ?

Thanks!

Have a look at this PHP example of xmlrpc authentication: http://drupal.org/node/774298

At the bottom of that link I show how the code at the top of the link is used, with the key bits being the following steps:

  1. first you do a system.connect() to get your session id as an anonymous user
  2. then you call user.login() with all the 7 parameters you've already identified

You actually work with two session ids - the anonymous one is required for login, and after successful login you get a new session id that is for all future uses during that session.

The username and password need to be a valid username and password to the drupal site you're connecting.

Things are getting better

Ok guys,

First, thanks to DrupalCloud, I've updated my code.
Things are getting better in a way that the server reply that the username/password are not good.

This is the code:

                final XMLRPCMethod method1 = new XMLRPCMethod("user.login", new XMLRPCMethodCallback() {
                    public void callFinished(Object result) {
                        Log.d(GlobalDataStore.TAG, "result=" + result.toString());
                        testResult.setText(result.toString());
                    }
                });
                XMLRPCMethod method2 = new XMLRPCMethod("system.connect", new XMLRPCMethodCallback() {
                    public void callFinished(Object result) {

                        final Long timestamp = new Date().getTime() / 100;
                        final String time = timestamp.toString();
                        GlobalDataStore.nonce = GetNonce(10);

                        StringBuilder sb = new StringBuilder();
                        sb.append(time);
                        sb.append(";");
                        sb.append(GlobalDataStore.domainname);
                        sb.append(";");
                        sb.append(GlobalDataStore.nonce);
                        sb.append(";");
                        sb.append("user.login");

                        Mac hmac;
                        try {
                            hmac = Mac.getInstance("HmacSHA256");
                            hmac.init(new SecretKeySpec(GlobalDataStore.drupalkey.getBytes(),hmac.getAlgorithm()));
                            hmac.update(sb.toString().getBytes());
                            GlobalDataStore.hash = new String(Hex.encodeHex(hmac.doFinal()));
                        } catch (NoSuchAlgorithmException e2) {
                            // TODO Auto-generated catch block
                            e2.printStackTrace();
                        } catch (InvalidKeyException e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }                      
                       

                        GlobalDataStore.sessid = (String) ((Map) result).get("sessid");

                        Log.d(GlobalDataStore.TAG, "string to hash=" + sb.toString());
                        Log.d(GlobalDataStore.TAG, "hash=" + GlobalDataStore.hash);
                        Log.d(GlobalDataStore.TAG, "key=" + GlobalDataStore.drupalkey);
                        Log.d(GlobalDataStore.TAG, "timestamp=" + time);
                        Log.d(GlobalDataStore.TAG, "nonce=" + GlobalDataStore.nonce);
                        Log.d(GlobalDataStore.TAG, "sessid=" + GlobalDataStore.sessid);
                        Log.d(GlobalDataStore.TAG, "user=" + GlobalDataStore.user);
                        Log.d(GlobalDataStore.TAG, "password=" + GlobalDataStore.password);

                        Object[] params = {
                                GlobalDataStore.hash,GlobalDataStore.domainname,time,GlobalDataStore.nonce,"user.login",GlobalDataStore.drupalkey,GlobalDataStore.sessid,GlobalDataStore.user,GlobalDataStore.password
                        };
                                               
                        method1.call(params);
                       
                    }
                });
                method2.call();
                }

Here is what I get in the log:

The user password, key and domain name has been changed of course and I'm using the good one in my code.

I tried to change the api key and I got an error saying that the api key is wrong, so I suppose the problem is coming from elsewhere...

REST/JSON

Posted by recidive on April 30, 2010 at 5:35am

In Android it's a lot easier to consume REST/JSON servers since there's build in support for JSON and simple HTTP requests.

We used REST server + this JSON output patch to expose a simple REST/JSON server to Android.

The client for logging the user in would be as easy as accessing this URL:

http://site.com/services/rest?method=system.connect

Parsing it's JSON serialized result, for getting the session id, then calling this

http://site.com/services/rest?method=user.login&sessid=<sessid>&username=<username>&password=<password>

passing user credentials and session id from system.connect.

The result will be either an object representing the user or an error.

All this is for Services 1.x, though.

If you use at least 2.x of

If you use at least 2.x of the REST server no hack is needed for JSON output.

I succeded to get it working thanks to DrupalCloud sources.

I'll forget XMLRPC !

I still have a question in my mind, is it possible to post images (CCK Fields) through those services and using POST ?

Is there a limit in size ?

Thanks!

I'm trying to connect my Android App with Drupal Services. There is an error on the Log Console, but I think I've done everything well. Here is the code. Can you have a look please?

public void onCreate(Bundle savedInstanceState) {

    //http://thetimebird6.atenealabs.com/?q=services/xmlrpc
    //http://thetimebird6.atenealabs.com/xmlrpc.php

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main);
    TextView session = (TextView)findViewById(R.id.session);

    DrupalXmlRpcService service = new DrupalXmlRpcService("thetimebird6.atenealabs.com","24aeee489fae05abaca3cd9cee2a04fe","http://thetimebird6.atenealabs.com/services/xmlrpc");
    if(service.Connect() == true) {
            session.setText(service.Login("user", "pass"));
            service.Logout();
    }
    else{
            session.setText("incorrect");
    }
}

and log error is :
