Question

我正在使用自动化安装火狐扩展。我正在使用下面的代码。但我有个错误。

在此输入图像说明

package com.toolbar.pages;

import java.io.Console;

import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.sikuli.script.FindFailed;
import org.sikuli.script.ImagePath;
import org.sikuli.script.Pattern;
import org.sikuli.script.Screen;

public class FFInstallationpage {

	@SuppressWarnings("deprecation")
	public static void main(String[] args) throws FindFailed, InterruptedException {
		
		WebDriver driver;
		
		DesiredCapabilities capabilities = new DesiredCapabilities();
		
		System.setProperty("webdriver.gecko.driver", "/Users/venkata.b/Downloads/geckodriver");
		
		driver =new FirefoxDriver(capabilities);
   
        driver.manage().window().maximize();
        
        driver.get("https://toolbar.rakuten.co.jp/ff/");
      
        driver.findElement(By.xpath("//img[contains(@src,'https://image.infoseek.rakuten.co.jp/content/toolbar/ff/top/main_btn.png')]")).click();
        
        Thread.sleep(5000);
   
        driver.findElement(By.xpath("//img[contains(@src,'https://image.infoseek.rakuten.co.jp/content/toolbar/install_btn.gif')]")).click();
    
   
       
        Alert alert = driver.switchTo().alert();
        
        driver.switchTo().alert();
        
        alert.accept();

Answer 1

如果您需要警报，但有时它可能无法打开。您可以使用try和catch来处理警报

try {
Alert alert = driver.switchTo().alert(); 

        driver.switchTo().alert(); 

        alert.accept(); 
}

catch (org.openqa.selenium.NoAlertPresentException e){
 System.out.println("No alert present");      
}
