抓取网站时隐藏 Chrome window

Question

我从事网络爬虫有一段时间了。现在一切正常，但我想对我的程序进行最后的修改，并在进程运行.

时隐藏 Chrome windows 不可见

我已经尝试将这个添加到我的代码中：

var chromeDriverService = ChromeDriverService.CreateDefaultService();
chromeDriverService.HideCommandPromptWindow = true;
return new ChromeDriver(chromeDriverService,  new ChromeOptions());

但是一直没有成功。有人可以提示我应该如何添加此隐藏命令才能正常工作吗？我应该如何修改我当前的代码来实现后台运行?

这是我的代码：

using System.Linq;
using OpenQA.Selenium.Chrome;

namespace WebDriverTest
{
    class Program
    {
        static void Main(string[] args)
        {
            // Initialize the Chrome Driver
            using (var driver = new ChromeDriver())
            {
                // Go to the home page
                driver.Navigate().GoToUrl("xxx.com");
                driver.Manage().Timeouts().ImplicitWait = System.TimeSpan.FromSeconds(15);
                // Get the page elements
                var userNameField = driver.FindElementById("loginForm:username");
                var userPasswordField = driver.FindElementById("loginForm:password");
                var loginButton = driver.FindElementById("loginForm:loginButton");

                // Type user name and password
                userNameField.SendKeys("username");
                userPasswordField.SendKeys("password");

                // and click the login button
                loginButton.Click();

                // Extract the text and save it into result.txt
                // var result = driver.FindElementByXPath("//div[@id='case_login']/h3").Text;
                // File.WriteAllText("result.txt", result);

                // Take a screenshot and save it into screen.png
                driver.GetScreenshot().SaveAsFile(@"screen.png", OpenQA.Selenium.ScreenshotImageFormat.Png);
            }
        }

    }
}

Answer 1

您是否尝试添加：

var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments("headless");

Answer 2

好的，经过一番调查，应该是：

using System.Linq;
using OpenQA.Selenium.Chrome;
using Scripting;
using System.IO;

namespace WebDriverTest
{
    class Program
    {
        static void Main(string[] args)
        {

            var chromeOptions = new ChromeOptions();
            chromeOptions.AddArguments("headless");

            // Initialize the Chrome Driver
            using (var driver = new ChromeDriver(chromeOptions))
            {
                // Go to the home page
                driver.Navigate().GoToUrl("xxx.com");
                driver.Manage().Timeouts().ImplicitWait = System.TimeSpan.FromSeconds(15);
                // Get the page elements
                var userNameField = driver.FindElementById("loginForm:username");
                var userPasswordField = driver.FindElementById("loginForm:password");
                var loginButton = driver.FindElementById("loginForm:loginButton");

                // Type user name and password
                userNameField.SendKeys("username");
                userPasswordField.SendKeys("password");

                // and click the login button
                loginButton.Click();

                // Extract the text and save it into result.txt
                // var result = driver.FindElementByXPath("//div[@id='case_login']/h3").Text;
                // File.WriteAllText("result.txt", result);

                // Take a screenshot and save it into screen.png
                driver.GetScreenshot().SaveAsFile(@"screen.png", OpenQA.Selenium.ScreenshotImageFormat.Png);
           }
        }

    }
}
