使用Selenium+ChromeDriver登錄微博並且獲取cookie

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

　　 public class GetSinaCookie
    {
        private static string userName = "name";
        private static string paw = "passward";
        public static void RefreshCookie()
        {
            
            // https://weibo.com
            var url = "https://weibo.com";
            var driver = new ChromeDriver();
             driver.Navigate().GoToUrl(url);
            Thread.Sleep(15 * 1000);
            var btn = driver.FindElement(By.XPath("//a[@node-type='loginBtn']"));
            btn.Click();
            Thread.Sleep(10 * 1000);
            var temp = driver.FindElements(By.XPath("//a[@node-type='submitBtn']"));
            var oun = temp.Count();
            var userNameinput = driver.FindElement(By.XPath("//input[(@node-type='username') and (@tabindex = '3')]"));
            var pawInput = driver.FindElements(By.XPath("//input[(@name='password')]")).ToArray()[2]; //driver.FindElement(By.XPath("//input[(@name='password')]"));
            var loginbtn = driver.FindElements(By.XPath("//a[@node-type='submitBtn']")).ToArray()[2];
            userNameinput.SendKeys(userName);
            Thread.Sleep(5 * 1000);
            pawInput.SendKeys(paw);
            loginbtn.Click();

　　　　　　　Thread.Sleep(2 * 1000);

　　　　　　　var dd = driver.Manage().Cookies.AllCookies.ToDictionary(cookie => cookie.Name, cookie => cookie.Value); StringBuilder strBuilder = new StringBuilder(); foreach (var d in dd) { var line = d.Key + "=" + d.Value + "; "; strBuilder.Append(line); } var cookieStr = strBuilder.ToString().Trim(); cookieStr = cookieStr.Substring(0, cookieStr.Length - 1); driver.Close(); driver.Quit(); } }

 注意點：

1、在獲取節點前、點擊按鈕前、點擊按鈕后、以及獲取cookie前的操作，要暫停一下，比如暫停2到3秒，防止節點或者頁面沒有加載完成導致無法獲取節點或者給節點賦值不正確等錯誤

2、以上代碼僅適用於不需要輸入驗證碼的情況。
