如何使用Java中的htmlunit登录到Twitter？

Question

I am trying to login to Twitter using Java's htmlunit packages. But I get the error: com.gargoylesoftware.htmlunit.html.HtmlPasswordInput cannot be cast to com.gargoylesoftware.htmlunit.html.HtmlTextInput

    WebClient webClient = new WebClient(BrowserVersion.CHROME);
    HtmlPage page = webClient.getPage("https://www.twitter.com/");
    HtmlForm form = page.getForms().get(1);
    form.reset();
    HtmlTextInput username = form.getInputByName("session[password]");

    username.setText("xxxxxxx");

    HtmlPasswordInput password = form.getInputByName("session[password]");

    password.setText("xxxxxxx");

    HtmlInput button = form.getInputByValue("Log in");
    webClient.getOptions().setThrowExceptionOnScriptError(false);
    HtmlPage p = button.click();

Answer 1

The following line in your code causes the problem

HtmlTextInput username = form.getInputByName("session[password]");

It should be

HtmlTextInput username = form.getInputByName("session[username_or_email]");
