【中文标题】无法在 webdriver 中单击警报【英文标题】：Not able to click alerts in webdriver 【发布时间】：2018-02-08 14:40:34 【问题描述】：我想解除警报。我尝试了以下两种方法，没有任何效果。
有人能解释一下这是怎么回事吗？
我使用的环境是...selenium-3.8.1, FF 53, Windows 7, gecko driver 16。
另外，我尝试使用 selenium-3.8.1、chrome 64、Windows 7、chrome driver win 32
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class RedbusAlert
public static void main(String[] args) throws InterruptedException
System.setProperty("webdriver.gecko.driver", "I:\\Selenium\\geckodriver-v0.16.0-win64\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
//Method 1
driver.get("https://www.redbus.in/");
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
Alert alert=driver.switchTo().alert();
String alertMessage=alert.getText();
System.out.println(alertMessage);
alert.dismiss();
//Method 2
// driver.get("https://www.redbus.in/");
// WebDriverWait wait= new WebDriverWait(driver, 20);
// Alert alertMessage2=wait.until(ExpectedConditions.alertIsPresent());
// System.out.println("alert message"+alertMessage2.getText());
// alertMessage2.dismiss();
请查看以下每种方法的结果和警报图片 Alert Image

【问题讨论】：
【参考方案1】：这不是警告框，它是Selenium Alert 类无法处理的浏览器通知警告。可能有两种处理方式...
您可以使用ChromeOptions禁用它的一种方法
ChromeOptions options = new ChromeOptions();
options.addArguments("--disable-notifications");
WebDriver driver = new ChromeDriver(options);
您需要使用ChromeOptions 创建chrome preference map 的其他方式如下...
ChromeOptions options = new ChromeOptions();
Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("profile.default_content_setting_values.notifications",1);
options.setExperimentalOption("prefs", prefs);
WebDriver driver = new ChromeDriver(options);
【讨论】：
感谢@Gaurav 的工作。请您回答以下2个问题。 1. 有没有办法在通知中选择“允许”、“阻止”等选项。 2.火狐浏览器禁用通知的代码是什么以上是关于无法在 webdriver 中单击警报的主要内容，如果未能解决你的问题，请参考以下文章
