[Htmlunit-user] Quickbooks Online OAuth

[Mark F. <sen...@gm...>]

Hi htmlunit users,

Has anyone successfully used htmlunit with Quickbooks Online's (QBO) OAuth
process?  Somewhat different from other OAuth examples and can't seem to
navigate through the various pages.

I successfully provide credentials and submit the first form but
immediately face trouble.
Depending upon the number of QBO company files, the next form requires
company selection or, if only one exists, form redirects to final form with
"Authorize" button.

I only have one company file at the moment so expecting to find the
Authorize button...

final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_38);
webClient.setAjaxController(new NicelyResynchronizingAjaxController());
final HtmlPage page1 = webClient.getPage(url);
HtmlForm form = null;
for (int i = 0; i < 20; i++) {
            if ((form =
page1.getFirstByXPath("//*[@id='ius-sign-in']/form")) != null) {
                break;
            }
            synchronized (page1) {
                page1.wait(500);
            }
}
final HtmlSubmitInput button = form.getInputByName("SignIn");
final HtmlTextInput textField = form.getInputByName("Email");
final HtmlPasswordInput textField2 = form.getInputByName("Password");
// Change the value of the text field
textField.setValueAttribute(QBO_USERNAME);
textField2.setValueAttribute(QBO_PASSWORD);
final HtmlPage page2 = button.click();
/*/Above appears to work..here's where I expect the Authorize button on a
form...*
for (int i = 0; i < 20; i++) {
            if ((form = page2.getFirstByXPath("//*[@id='grantForm']")) !=
null) {
                break;
            }
            synchronized (page2) {
                page2.wait(500);
            }
}

'form' value is always null regardless of the loop length above.  I've
tried xpath searching for the button id as well but still no joy.

Plenty of htmlunit warnings but process continues even after the
following...
