如何使用 selenium.WebDriver 和 HtmlUnitDriver 注销 Facebook

Question

我正在使用 selenium.WebDriver 和 HtmlUnitDriver 登录到 Facebook，但我无法注销。

public static void main(String[] args) throws InterruptedException {

WebDriver driver = new HtmlUnitDriver();
driver.get("http://www.facebook.com");
System.out.println("Title of the page "+ driver.getTitle());
WebElement username = driver.findElement(By.id("email"));
username.sendKeys("xxxxx@gmail.com"); 
WebElement password = driver.findElement(By.id("pass"));
password.sendKeys("xxxxx");
WebElement Signup_button = driver.findElement(By.id("loginbutton"));
Signup_button.click();
Thread.sleep(5000);
System.out.println("After login title is = " + driver.getTitle());

到现在为止它有效。 并且以下步骤涵盖了注销部分（不起作用）：

WebElement logOut = driver.findElement(By.id("userNavigationLabel"));
logOut.click();
Thread.sleep(5000);
WebElement signOut = driver.findElement(By.name("Log Out"));
logOut.click();

System.out.println("Logged Out Successfully!!!!!!!!!!!!!!!!!!!");
String pagetitle = driver.getTitle();
System.out.println(pagetitle);

}}

错误：

Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate element with name: Log Out

Facebook 注销 html 代码

<span><span class="_54nh"><form class="_w0d"
 action="https://www.facebook.com/logout.php" data-nocookies="1" 
id="show_me_how_logout_1" method="post" onsubmit="return window.Event
 &amp;&amp; Event.__inlineSubmit &amp;&amp; 
Event.__inlineSubmit(this,event)"><input name="fb_dtsg" 
value="AQGzvtPjFD1W:AQFslBEMcQG9" autocomplete="off" type="hidden"><input
 autocomplete="off" name="ref" value="mb" type="hidden"><input 
autocomplete="off" name="h" value="AfeziZXPRhN6ncxD" type="hidden">
</form>Log Out</span></span>

我也尝试过 Saurabh Gaur Selenium WebDriver 从 Facebook 注销的代码

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement accountSettings = wait.until(ExpectedConditions.elementToBeClickable(By.linkText("Account Settings")));
accountSettings.click() //this will click on setting link to open menu
WebElement logOut = wait.until(ExpectedConditions.elementToBeClickable(By.linkText("Log Out")));
logOut.click() // this will click on logout link

错误

Facebook 注销

线程.sleep(3000);

driver.findElement(By.xpath("//div[contains(@id,'userNavigationLabel')]")).click();

线程.sleep(3000);

driver.findElement(By.xpath("//span[@class='_54nh'][contains(.,'Log Out')]")).click();

Answer 2

名称（定位器）中没有属性，请使用另一个属性（定位器）作为 id="show_me_how_logout_1" 或任何其他定位器。

Answer 3

试试下面的代码。

WebElement logOut = driver.findElement(By.id("userNavigationLabel"));
logOut.click();

signOut.click();
