Question

我的问题是我如何执行点击元素以从服务器响应中获取数据？算法：
1）点击div元素

<div class="contact-button link-phone {'path':'phone', 'id':'z8rpg', 'id_raw': '519183738'} atClickTracking contact-a" data-rel="phone"> 
    <i data-icon="phone"></i> 
    <strong class="xx-large"> TEXT1 </strong> 
</div>

2）向服务器发送请求
3）服务器发送带有修改文本的响应。所以我需要获得修改后的文本（代码中的TEXT1）。我这样做了：

HtmlUnitDriver driver = new HtmlUnitDriver(BrowserVersion.CHROME);
        driver.get("https://www.olx.ua/obyavlenie/audi-a4-1998-IDzaH8c.html#c890172227;promoted");
        System.out.println("Title: " + driver.getTitle());
        WebElement webElement = driver.findElement
                (By.xpath("//*[@id=\"contact_methods\"]/li[2]/div"));
        webElement.click();
        Thread.sleep(3000);
        webElement = driver.findElement
                (By.xpath("//*[@id=\"contact_methods\"]/li[2]/div"));
        phone = webElement.getText();

更新：

据我所知，从服务器div元素获取响应后重新加载，而不是整页。我需要等到div元素重新加载完毕。使用调试模式我注意到奇怪的事情。在这一行：

phone = webElement.getText();

webElement的状态：readyState_ =＆＃34; loading＆＃34;

Answer 1

采取的步骤：

导航至https://www.olx.ua/obyavlenie/audi-a4-1998-IDzaH8c.html#c890172227;promoted
单击屏幕右侧的Показать（span）。
我们点击它后会立即看到两个数字。
检索这两个数字并将其打印在控制台上。

代码：Java + Selenium

public class Lesnov {

    static WebDriver driver;
    static WebDriverWait wait;

    public static void main(String[] args) throws InterruptedException {
         System.setProperty("webdriver.chrome.driver", "D:\\Automation\\chromedriver.exe");
            driver = new ChromeDriver();
            driver.manage().window().maximize();
            wait = new WebDriverWait(driver, 40);
            driver.get("https://www.olx.ua/obyavlenie/audi-a4-1998-IDzaH8c.html#c890172227;promoted");
            wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("div[class^='contact-button']")));
            wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("span[class='spoiler']")));
            driver.findElement(By.cssSelector("span[class='spoiler']")).click();
            wait.until(ExpectedConditions.presenceOfAllElementsLocatedBy(By.cssSelector("strong[class='xx-large']>span[class='block']")));
            List<WebElement> numbers = driver.findElements(By.cssSelector("strong[class='xx-large']>span[class='block']"));
            for(WebElement num : numbers){
                System.out.println(num.getText());
            }

    }

    }

更新

您可以将此代码与htmlunitDriver一起使用;

public class Lesnov {

    static WebDriver driver;
    static WebDriverWait wait;

    public static void main(String[] args) throws InterruptedException {
         System.setProperty("webdriver.chrome.driver", "D:\\Automation\\chromedriver.exe");
         WebDriver driver = new HtmlUnitDriver(BrowserVersion.CHROME ,true);
            driver.manage().window().maximize();
            wait = new WebDriverWait(driver, 40);
            driver.get("https://www.olx.ua/obyavlenie/audi-a4-1998-IDzaH8c.html#c890172227;promoted");
            wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("div[class^='contact-button']")));
            wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("span[class='spoiler']")));
            driver.findElement(By.cssSelector("span[class='spoiler']")).click();
            wait.until(ExpectedConditions.presenceOfAllElementsLocatedBy(By.cssSelector("strong[class='xx-large']>span[class='block']")));
            List<WebElement> numbers = driver.findElements(By.cssSelector("strong[class='xx-large']>span[class='block']"));
            for(WebElement num : numbers){
                System.out.println(num.getText());
            }

    }

    }

HtmlUnitDriver单击并等待重新加载元素
