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会导致异常调用提交。 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。
以下是表格：

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<WebElement> 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stacktrace：
