Given an HtmlUnit HtmlPage object, how do I get the URI of its Document?

The page object I have is the result of a long chain of click() calls (just in case you were wondering how I could have a page object without knowing the URL used to obtain it).

• The method HtmlPage.getDocumentURI is not implemented.
• Htm开发者_如何学PythonlPage.getOwnerDocument returns null.
• page.executeJavaScript("return document.location").getJavaScriptResult() also returns null.

Any hints?

The answer is of course to realize that executeJavaScript should have been called evalJavaScript, and write something like

page.executeJavaScript("document.location").getJavaScriptResult()

page.getUrl()

worked fine for me.
