Java HttpClient and Devise Authentication Issues

Question

I'm running devise on a web server and I'm trying to get a Java application to authenticate. After the application is authenticated, devise should authorize the application to create and update records on the web server.

I'm looking at the rails server log, to compare what the web form is posting versus my application. Here are the different outputs:

Web Form (Working)

Parameters: {"utf8"=>"Γ£ô", "authenticity_token"=>"vYC9qd0dVIUH7B/wCHW59JwZquX4yaiogXZ32pbn1So=", "user"=>{"username"=>"user", "password"=>"[FILTERED]", "remember_me"=>"0"}, "commit"=>"Sign in"}

Application (Not Working)

Parameters: {"utf8"=>"?", "username"=>"user", "password"=>"[FILTERED]", "commit"=>"Sign in"}

This is my app's code

    public void webLogin(String methodName, String username, String password) {        
        httpPost = new HttpPost(webServiceUrl+methodName);

        try {
            // Add your data
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair("utf8", Character.toString('\u2713')));
            nameValuePairs.add(new BasicNameValuePair("username", username));
            nameValuePairs.add(new BasicNameValuePair("password", password));
            nameValuePairs.add(new BasicNameValuePair("commit", "Sign in"));
            httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            // Execute HTTP Post Request
            HttpResponse response = httpClient.execute(httpPost);

        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
        } catch (IOException e) {
            // TODO Auto-generated catch block
        }
    }

The obvious difference is that the username and password are nested into a user structure. So my question is, how do I create that structure?

Answer 1

Seeing as to what kind of request is working, I'd try this:

nameValuePairs.add(new BasicNameValuePair("authenticity_token", myToken));
nameValuePairs.add(new BasicNameValuePair("user[username]", username));
nameValuePairs.add(new BasicNameValuePair("user[password]", password));
nameValuePairs.add(new BasicNameValuePair("user[remember_me]", 0));
nameValuePairs.add(new BasicNameValuePair("commit", "Sign in"));
