Selenium Htmlunitdriver 无法正常工作，尽管 FirefoxDriver 可以工作

Question

为什么这段代码在 HtmlUnitDriver 中产生"失败"，而在 FirefoxDriver 中产生"成功"？它尝试捕获在页面其余部分几秒钟后加载的文本。我需要HtmlUnitDriver的"成功"。

//      WebDriver driver = new HtmlUnitDriver();
        WebDriver driver = new FirefoxDriver();
        driver.get("https://www.zoro.com/i/G1237047/");
        for (int i = 0; i < 360; i++) 
            if (driver.getPageSource().contains("<span id="availability")) {
                Thread.sleep(500);
                break;
            }
            Thread.sleep(500);
        if (driver.findElement(By.id("price-box-ships-from-zoro")).getText().contains("1 business day"))
            System.out.println("Success");
        else
            System.out.println("Failure");

Answer 1

尝试以下代码：

  for (int i = 0; i < 360; i++) 
            if (driver.getPageSource().contains("<span id="availability")) {
                Thread.sleep(500);
                break;
            }
     String e = driver.findElement(By.xpath("//strong[contains(text(),'1 business day')]")).getText();
     System.out.println(e);
            Thread.sleep(500);
            if (e.contains("1 business day"))
                System.out.println("Success");
            else
                System.out.println("Failure");

也单独获取它们：尝试以下

第一行：

String a = driver.findElement(By.xpath("//div[@id='ships-from-lead-time-G1237047'][@class='ships-from-lead-time']")).getText();
String b = driver.findElement(By.xpath(".//strong[contains(text(),'1 business day.')]")).getText();
System.out.println(a);
System.out.println(b);

第二行：

String c =driver.findElement(By.xpath("//span[@id='price-box-ships-free']")).getText();
System.out.println(c);

第三行：

String d = driver.findElement(By.xpath("//span[@id='price-box-standard-ground']")).getText();
System.out.println(d);
