C# WebBrowser Automation Login

首先需要安裝套件

其一：Selenium.WebDriver

 NuGet\Install-Package Selenium.WebDriver -Version 4.5.1

其二：Selenium.WebDriver.ChromeDriver ( 版本需依據本地Chrome的版本微調)

 NuGet\Install-Package Selenium.WebDriver.ChromeDriver -Version 106.0.5249.6100

以登入Netflix為例 使用以下範例

  using OpenQA.Selenium;
  using OpenQA.Selenium.Chrome;
  using System.Threading;

  namespace WebBrowser_AutoLogin
  {
      internal class Program
      {
          static void Main(string[] args)
          {
              IWebDriver driver = new ChromeDriver();
              //開啟網頁
              string str = "https://www.netflix.com/tw/Login";
              driver.Navigate().GoToUrl(str);
       
              IWebElement inputAccount = driver.FindElement(By.Name("userLoginId"));
              Thread.Sleep(50);
              inputAccount.SendKeys("Account"); //輸入帳號
              Thread.Sleep(50);

              IWebElement inputPassword = driver.FindElement(By.Name("password"));
              Thread.Sleep(50);
              inputPassword.SendKeys("Password"); //輸入密碼
              Thread.Sleep(50);
              //登入
              IWebElement submitButton = driver.FindElement(By.XPath("//*[@class='btn login-button btn-submit btn-small']"));
              Thread.Sleep(50);
              submitButton.Click();
          }
      }
  }

參數來源

執行GIF ，依照上面範例中的帳號密碼的輸入的話，理所當然會在Cick Login之後顯示帳號或密碼錯誤

額外需求補充 如果要點擊某個button,但是html都長一樣的話,像以下範例一樣,使用XPath彙整出陣列,在進行enter

IReadOnlyCollection<IWebElement> ConsoleCLI = driver.FindElements(By.XPath("//*[@class='console-controls ng-star-inserted']/button"));
ConsoleCLI.ToList()[3].SendKeys(Keys.Enter);
