selenium表格提交

我正在尝试使用selenium自动化表单提交。 但是，点击登录时运行的JavaScript会导致exception调用提交。 Selenium将提交指向localhost，而不是表单操作。 任何人都可以解释为什么会发生这种情况并善意地提供解决方案来解决这个问题。

这是表格：

 Example 
 
 
 
  function postOk() { document.forms[0]['pf.ok'].value = 'clicked'; document.forms[0].submit(); } function postCancel() { document.forms[0]['pf.cancel'].value = 'clicked'; document.forms[0].submit(); } function postOnReturn(e) { var keycode; if (window.event) keycode = window.event.keyCode; else if (e) keycode = e.which; else return true; if (keycode == 13) { document.forms[0].submit(); return false; } else { return true; } } function setFocus() { var platform = navigator.platform; if(platform != null && platform.indexOf("iPhone") == -1) { document.getElementById('username').focus(); } } function setMobile(mobile) { var className = ' mobile', hasClass = (bodyTag.className.indexOf(className) !== -1); if(mobile && !hasClass) { bodyTag.className += className; } else if (!mobile && hasClass) { bodyTag.className = bodyTag.className.replace(className, ''); } } function getScreenWidth() { return (window.outerHeight) ? window.outerWidth : document.body.clientWidth; } var bodyTag = document.getElementsByTagName('body')[0], width = getScreenWidth(), remember = false && false; if(/Android|webOS|iPhone|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent)) { setMobile(true); } else { setMobile((width <= 480)); window.onresize = function() { width = getScreenWidth(); setMobile((width <= 480)); } }    

这是我的Java代码：

  private final static String PF_BASE_URL = "https://machine.place.domain.com"; private final static String PF_PRIMARY_SSL_PORT = "9031"; private final static String PF_START_SSO_ENDPOINT = "/sp/startSSO.ping"; private final static String PARTNER_ENTITY_ID = "LDAPTest:SAML2:IDP"; try{ DesiredCapabilities capability = DesiredCapabilities.internetExplorer(); capability.setJavascriptEnabled(true); WebDriver driver = new HtmlUnitDriver(capability); driver.get(PF_BASE_URL + ":" + PF_PRIMARY_SSL_PORT + PF_START_SSO_ENDPOINT + "?" + "PartnerIdpId="+ PARTNER_ENTITY_ID); HtmlUnitWebElement formElement = (HtmlUnitWebElement) driver.findElement(By.tagName("form")); String actionURL = formElement.getAttribute("action"); String newactionURL = PF_BASE_URL + ":" + PF_PRIMARY_SSL_PORT + actionURL; String script = "document.forms[0].action='"+newactionURL+"'"; if(driver instanceof JavascriptExecutor){ ((JavascriptExecutor) driver).executeScript(script); } HtmlUnitWebElement usernameElement = (HtmlUnitWebElement) driver.findElement(By.id("username")); usernameElement.sendKeys("user"); HtmlUnitWebElement passwordElement = (HtmlUnitWebElement) driver.findElement(By.id("password")); passwordElement.sendKeys("password"); List anchors = driver.findElements(By.tagName("a")); for (int i = 0; i < anchors.size(); i++) { String title = anchors.get(i).getAttribute("title"); if (title.equalsIgnoreCase("Sign on")) { anchors.get(i).click(); break; } } driver.close(); } catch (Exception e){ System.out.println(e.tostring()); } 

这是堆栈跟踪：

来自Selenium wiki ：

没有一个流行的浏览器使用HtmlUnit（Rhino）使用的javascript引擎。 如果您使用HtmlUnit测试javascript，结果可能与这些浏览器有很大不同。

换句话说：如果您依赖JavaScript，请不要使用HtmlUnit。 如果您需要无头浏览器，请考虑使用PhantomJS 。
