问题
I am trying automate login to gmail but its not working. I am using HtmlUnit for form,textbox and submit button access. On passing correct username and password it displays all the services but in the end when i open gmail it shows the login page.
This is my code
final WebClient webClient = new WebClient(BrowserVersion.CHROME);
// Get the first page
webClient.getOptions().setJavaScriptEnabled(true);
webClient.getCookieManager().setCookiesEnabled(true);
webClient.getOptions().setCssEnabled(false);
webClient.getOptions().setUseInsecureSSL(true);
webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
try {
final HtmlPage page1 = webClient.getPage("http://www.gmail.com/");
final HtmlForm form = page1.getForms().get(0);
final HtmlSubmitInput button = form.getInputByName("signIn");
final HtmlTextInput textField = form.getInputByName("Email");
final HtmlPasswordInput pwd = form.getInputByName("Passwd");
textField.setValueAttribute("username");
pwd.setValueAttribute("password");
System.out.println(page1.asText());
final HtmlPage page2 = (HtmlPage) button.click();
String htmlBody = page2.getWebResponse().getContentAsString();
System.out.println(page2.asText());
System.out.println("Base Uri 1 : " + page1);
System.out.println("Base Uri 2 : " + page2);
webClient.closeAllWindows();
} catch (Exception e) {
// TODO: handle exception
}
This is Error Log i am getting

Loading standard view | Load basic HTML (for slow connections)
This is taking longer than usual. Try reloading the page.
If that doesn't work, you can:
1. Disable Labs and try again.
2. If you're on a slow connection, try basic HTML view.
3. For more troubleshooting tips, visit the help center.

It's possible that the built-in browser can't parse the Javascript correctly.
Try emulating a different browser. From the docs:
Often you will want to simulate a specific browser. This is done by passing a com.gargoylesoftware.htmlunit.BrowserVersion into the WebClient constructor. Constants have been provided for some common browsers but you can create your own specific version by instantiating a BrowserVersion.
@Test
public void homePage_Firefox() throws Exception {
final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_17);
final HtmlPage page = webClient.getPage("http://htmlunit.sourceforge.net");
Assert.assertEquals("HtmlUnit - Welcome to HtmlUnit", page.getTitleText());
webClient.closeAllWindows();
}
This snippet emulates Firefox v17. You can see the full list of supported, emulatable browsers in these javadocs. Today, these are:
static BrowserVersion CHROME
static BrowserVersion FIREFOX_17
static BrowserVersion FIREFOX_24
static BrowserVersion INTERNET_EXPLORER_11
static BrowserVersion INTERNET_EXPLORER_8
static BrowserVersion INTERNET_EXPLORER_9
