使用HtmlUnit时如何“解决” Steam登录？

Question

I want to write a java program which can browse webpage associated with steam . The problem is that I don't understand how steam automatically logs in users.

I figured these services use some kind of a cookies, but i couldn't find those cookies in chrome cookie manager. So even if I write a program which clicks the login button, then goes to the login page there fills it out, the secure page comes up which asks for email confirmation, which I can't and don't want to program. These sites are tf2outpost.com and backpack.tf .

Answer 1

Actually, there is an error with the website.

1. Go to http://www.tf2outpost.com/ with real browser
2. Click on 'Sign in through STEAM'
3. Check the source of the login page, at line #51 there is:

<script language="javascript">
    function Logout()
    {
        $('actionInput').value = 'steam_openid_logout';
        $('openidForm').submit();
    }

    >$J( function() { $J('#steamAccountName').focus() } );

</script>

The issue with >$J , which is incorrect JavaScript and is not tolerated by HtmlUnit.

To get around this, you can change the response as hinted here .

So you can have something like:

try (WebClient webClient = new WebClient(BrowserVersion.CHROME)) {
    new WebConnectionWrapper(webClient) {

        public WebResponse getResponse(WebRequest request) throws IOException {
            WebResponse response = super.getResponse(request);
            if (request.getUrl().toExternalForm().endsWith("identifier_select")) {
                String content = response.getContentAsString("UTF-8");
                content = content.replace(">$J( function()", "$J( function()");
                WebResponseData data = new WebResponseData(content.getBytes("UTF-8"),
                        response.getStatusCode(), response.getStatusMessage(), response.getResponseHeaders());
                response = new WebResponse(data, request, response.getLoadTime());
            }
            return response;
        }
    };

    HtmlPage page = webClient.getPage("http://www.tf2outpost.com");
    HtmlAnchor a = page.getAnchorByHref("/login");
    page = a.click();
    page.<HtmlInput>getHtmlElementById("steamAccountName").setValueAttribute(username);
    page.<HtmlInput>getHtmlElementById("steamPassword").setValueAttribute(password);
    page = page.<HtmlInput>getHtmlElementById("imageLogin").click();
    webClient.waitForBackgroundJavaScript(5000);
    System.out.println(page.asXml());

Still, here is captcha that came up.

Hope that helps.
