無法使用Selenium截取CEF應用程序的屏幕截圖

Question

我正在使用Selenium來自動化CEF應用程序。我成功地能夠執行像點擊等操作，但無法使用Selenium驅動程序截圖。因爲這是自動化所必需的特性。我怎樣才能做到這一點？

我使用了以下內容：

1. CEF應用 - sample application provided by CEF
2. selenium jar - selenium-server-standalone-3.0.1
3. cef_binary_3.2924.1564.g0ba0378_windows64_client
4. chromedriver

找到下面的代碼：

import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.WebElement; 
import org.openqa.selenium.chrome.ChromeDriver; 
import org.openqa.selenium.chrome.ChromeOptions; 
import org.openqa.selenium.TakesScreenshot; 
import org.openqa.selenium.OutputType; 

public class Example { 
    public static void main(String[] args) { 
     // Path to the ChromeDriver executable. 
     System.setProperty("webdriver.chrome.driver", "D:/CEFTesting/chromedriver.exe"); 
     // Path to the CEF executable. 
     ChromeOptions options = new ChromeOptions(); 

     options.setBinary("D:/CEFTesting/cef_binary_3.2924.1564.g0ba0378_windows64_client/Release/cefclient.exe"); 

     WebDriver driver = new ChromeDriver(options); 
     driver.get("http://www.google.com/xhtml"); 
     sleep(3000); // Let the user actually see something! 
     WebElement searchBox = driver.findElement(By.name("q")); 
     searchBox.sendKeys("ChromeDriver"); 
     searchBox.submit(); 
     sleep(5000); // Let the user actually see something! 

     String screenshotBase64 = ((TakesScreenshot) driver).getScreenshotAs(OutputType.BASE64); 
     System.out.println(screenshotBase64); 
     sleep(5000); // Let the user actually see something! 
     driver.quit(); 
    } 
} 

我正面臨錯誤。

我使用了以下內容：

1. CEF應用 -
2. 硒罐子 - 通過CEF（https://bitbucket.org/chromiumembedded/cef/wiki/UsingChromeDriver.md鏈接） - 提供了示例應用程序硒的服務器獨立-3.0.1
3. cef_binary_3。 2924.1564.g0ba0378_windows64_client
4. chromedriver

下面是代碼：

import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.WebElement; 
import org.openqa.selenium.chrome.ChromeDriver; 
import org.openqa.selenium.chrome.ChromeOptions; 
import org.openqa.selenium.TakesScreenshot; 
import org.openqa.selenium.OutputType; 

public class Example { 
    public static void main(String[] args) { 
     // Path to the ChromeDriver executable. 
     System.setProperty("webdriver.chrome.driver", "D:/CEFTesting/chromedriver.exe"); 
     // Path to the CEF executable. 
     ChromeOptions options = new ChromeOptions(); 

     options.setBinary("D:/CEFTesting/cef_binary_3.2924.1564.g0ba0378_windows64_client/Release/cefclient.exe"); 

     WebDriver driver = new ChromeDriver(options); 
     driver.get("http://www.google.com/xhtml"); 
     sleep(3000); // Let the user actually see something! 
     WebElement searchBox = driver.findElement(By.name("q")); 
     searchBox.sendKeys("ChromeDriver"); 
     searchBox.submit(); 
     sleep(5000); // Let the user actually see something! 

     String screenshotBase64 = ((TakesScreenshot) driver).getScreenshotAs(OutputType.BASE64); 
     System.out.println(screenshotBase64); 
     sleep(5000); // Let the user actually see something! 
     driver.quit(); 
    } 
}
