我对硒 3.13.0 和 chrome 版本 79.0.3945.130 和 java 有问题。我编写此代码用于测试必须在 2 个窗口之间切换的网页。当我开始运行此脚本时，一切正常，但是当驱动程序切换到新窗口时，它似乎不再可用！很长一段时间后，我得到了这个错误。 有谁知道问题出在哪里？
(我确信程序的控制会退出循环并切换到新窗口，但似乎驱动程序在离开循环后会丢失。
一些函数如driver.quit((或driver.getWindowHandles((在退出循环后工作，但其他一些函数如driver.getPageSource((或driver.manage((.window((.maximize((不起作用并导致此错误。
这是我的示例代码：
public class myClassFirst {
public static void main(String[] args) throws InterruptedException {
System.setProperty("webdriver.chrome.driver","Driver_Path");
WebDriver driver = new ChromeDriver();
driver.manage().window().maximize(); //it works correctly
driver.get("Web_page_Url");
Thread.sleep(15000); //to load page
System.out.println("finish waiting ...");
/*
some script here
*/
// go to appropriate frame
driver.switchTo().defaultContent();
driver.switchTo().frame("Faci3");
driver.switchTo().frame(driver.findElement(By.name("Commander")));
Set<String> s = driver.getWindowHandles();
System.out.println(s); //print windowID of current window(1)
//select button element
WebElement prepareToPrint = driver.findElement(By.id("PreparePrint"));
prepareToPrint.click();
Thread.sleep(5000); //to load new window(2)
String sThis = driver.getWindowHandle(); //get windowID of current window(1)
for (String winId:driver.getWindowHandles()) {
if (!winId.equals(sThis)) {
driver.switchTo().window(winId); //switch to new window(2)
System.out.println(winId); //print windowID of new window(2)
break;
}
}
System.out.println("exit from the loop");
driver.manage().window().maximize(); //From here does not work anymore(real line 92)
Actions builder = new Actions(driver);
builder.contextClick().perform();
System.out.println("End = Finish");
driver.quit();
}
}
这是输出：
finish waiting ...

Selenium WebDriver 默认等到页面完全加载。但是，您可以告诉它不要使用，或者使用另一个PageLoadStrategy。
以下内容应该对您有所帮助。
ChromeOptions options = new ChromeOptions();
options.setPageLoadStrategy(PageLoadStrategy.NONE);
当我在使用 EdgeDriver 遇到同样的问题时，这篇文章帮助了我。 https://www.skptricks.com/2018/08/timed-out-receiving-message-from-renderer-selenium.html
试试这个 driver.switchTo

。表示ChromeDriver无法切换到新的TAB。
您的主要问题是您使用的二进制文件版本之间的不兼容，如下所示：
您正在使用 chromedriver=79.0.3945.36- 和chrome=79.0.3945.130并且兼容
- 但是您的Selenium客户端版本是3.13.0的2018-06-25T15：32：14.902Z，几乎早了2年。
所以Selenium客户端v3.13.0，ChromeDriverv79.0和Chrome浏览器v79.0之间存在明显的不匹配

确保：
- JDK已升级到当前级别 JDK 8u222。
- 硒已升级到当前级别 版本 3.141.59。
- ChromeDriver已更新到当前的 ChromeDriver v79.0.3945.36 级别。 Chrome

- 通过IDE清理项目工作中心，并仅使用所需的依赖项重新生成项目。

在这个问题中，我将我的网络驱动程序从chrome更改为Firefox，并暂时解决了。 我希望这也对您有所帮助。
