Question

我已尝试过HTMLunit - Facebook Login和Using HTMLUnit to log into Facebook programmatically using Java中提供的代码。但是我没有登录Facebook。

启用javascript

webClient.setJavaScriptEngine(new JavaScriptEngine(webClient));
webClient.getOptions().setJavaScriptEnabled(true);

我得到了页面https://www.facebook.com/login.php?login_attempt=1&lwv=110。 htmlunit报告了几个警告和错误：

禁用javascript

webClient.setJavaScriptEngine(new JavaScriptEngine(webClient));
webClient.getOptions().setJavaScriptEnabled(false);

我得到了页面https://www.facebook.com/?sk=welcome。 eclipse控制台中的输出：

源代码：

final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_38);
webClient.setJavaScriptEngine(new JavaScriptEngine(webClient));
webClient.getOptions().setJavaScriptEnabled(false);
HtmlPage page1 = null;
try {
    page1 = webClient.getPage("http://www.facebook.com");
    System.out.println("1st page url: " + page1.getUrl());
    System.out.println("1st page title: " + page1.getTitleText());
    System.out.println("1st page body: " + page1.getBody());
} catch (IOException e) {
    e.printStackTrace();
}
final HtmlForm form = (HtmlForm) page1.getElementById("login_form");
final HtmlSubmitInput button = (HtmlSubmitInput) form.getInputsByValue("Log In").get(0);
final HtmlTextInput textField = (HtmlTextInput) page1.getElementById("email");
textField.setValueAttribute("myaddress@test.com");
final HtmlPasswordInput textField2 = (HtmlPasswordInput) page1.getElementById("pass");
textField2.setValueAttribute("mypassword");
try {
    HtmlPage page2 = button.click();
    System.out.println("2nd page url: " + page2.getUrl());
    System.out.println("2nd page title: " + page2.getTitleText());
    System.out.println("2nd page body: " + page2.getBody());
} catch (IOException e) {
    e.printStackTrace();
}

任何帮助将不胜感激。谢谢！
