使用硒的网络爬虫中的异常

Question

我正在学习网络爬行并尝试运行一个简单的程序来打印页面的标题。 但我收到了org.openqa.selenium.WebDriverException 。

我曾尝试将chromedriver.exe文件放在C驱动器中，也包括程序中的options.addArguments("--no-sandbox") ，但没有任何效果。 我已经重新安装了 chrome 并将其放置在 C:\\Users\\HP\\AppData\\Local\\Google\\Chrome\\Application\\chrome.exe 文件夹中，但这也不起作用。 首先它在 C:\\Program Files(x86)\\Google\\Chrome\\Application 文件夹中。 从该位置打开 chrome 时，它​​显示“应用程序无法正确启动（0xc0000022）。单击确定关闭应用程序”。

package LearnCrawling;

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.support.ui.WebDriverWait;

public class ExampleofCrawling {

    public static void main(String[] args) {        

        System.setProperty("webdriver.chrome.driver", 
                    "D:\\chromedriver\\chromedriver.exe");
        WebDriver driver = new ChromeDriver();

        driver.get("http://www.google.com");

        WebElement element = driver.findElement(By.name("q"));

        element.sendKeys("terminator\n");

        new WebDriverWait(driver, 10)
        .until(d -> d.getTitle().toLowerCase().startsWith("terminator"));

        System.out.println("Title: " + driver.getTitle());

        //driver.quit();

    }

}

我在 eclipse 窗口中收到以下错误：

我正在运行：Windows 10 (OS build 16299) Selenium 3.12.0 ChromeDriver 3.141.59 Chrome 73

有人对我可能做错了什么有任何建议吗？

Answer 1

您缺少 ChromeOptions：

ChromeOptions options = new ChromeOptions();
driver = new ChromeDriver(options);
