脚本问题或版本

Question

当我尝试执行脚本时，没有收到任何错误或异常，但功能不起作用。有人能告诉我为什么会这样吗。

Selenium version: selenium-server-4.0.0-beta-2 version.
chrome supported version: Version 89.0.4389.114

代码

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import static org.openqa.selenium.support.locators.RelativeLocator.withTagName;
public class Relative Locator 
{
public static void main(String[] args) throws Interrupted Exception
{
System.setProperty("webdriver.chrome.driver", "C:\Users\Amitava\eclipse-workspace\SeleniumForthEdition\driver\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("https://www.rahulshettyacademy.com/angularpractice/");
WebElement nameEditBox =driver.findElement(By.cssSelector("[name='name']"));    
Thread.sleep(5000);
System.out.println(driver.findElement(withTagName("label").above(nameEditBox)).getText());
Thread.sleep(5000);
WebElement email =driver.findElement(By.xpath("//*[contains(text(),'Email')]"));    
Thread.sleep(8000);
System.out.println("selenium-server-4.0.0-beta-2");
driver.findElement(withTagName("input").below(email)).sendKeys("[e-mail]");
}
}

控制台输出

Answer 1

检查这两个：

• 如何修复〔1573451709.039〕〔警告〕：连接Chrome超时，正在重试。。。同时使用chrome版本78和chrome驱动程序版本78.0.3904.70
• 当使用Chrome浏览器运行WebDriver时，收到消息，"；只允许本地连接"；即使浏览器正常启动

这似乎更像是版本控制问题

Answer 2

请在初始化chrome驱动程序时使用以下代码。看起来它没有接收来自web协议的传入消息。

System.setProperty("webdriver.chrome.whitelistedIps", "");
