c#使用Selenium相关总结

1、在 C# 中使用 Selenium WebDriver 执行 JavaScript

IWebDriver driver; // assume assigned elsewhere
IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
string title = (string)js.ExecuteScript("return document.title");

2､载取网页可视区域图片

public static void PageScreenshot(string url,string path)
        {
            ChromeDriver driver = null;
            try
            {
                ChromeOptions options = new ChromeOptions();
                options.AddArguments("headless", "disable-gpu");
                 driver = new ChromeDriver(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), options);
                driver.Navigate().GoToUrl(url);
                var screenshot = (driver as ITakesScreenshot).GetScreenshot();
                screenshot.SaveAsFile(path);
            }
            catch (Exception ex)
            {
                logger.Error(ex.Message+Environment.NewLine+ex.StackTrace);
            }
            finally
            {
                if (driver != null)
                {
                    driver.Close();
                    driver.Quit();
                }
            }
        }

3､载取网页有滚动条网页长图

public static void PageScreenshot(string url,string path)
        {
            ChromeDriver driver = null;
            try
            {
                ChromeOptions options = new ChromeOptions();
                options.AddArguments("headless", "disable-gpu");
                driver = new ChromeDriver(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), options);
                driver.Navigate().GoToUrl(url);
                string width = driver.ExecuteScript("return document.body.scrollWidth").ToString();
                string height = driver.ExecuteScript("return document.body.scrollHeight").ToString();
                driver.Manage().Window.Size = new System.Drawing.Size(int.Parse(width), int.Parse(height)); //=int.Parse( height);
                var screenshot = (driver as ITakesScreenshot).GetScreenshot();
                screenshot.SaveAsFile(path);
            }
            catch (Exception ex)
            {
                logger.Error(ex.Message+Environment.NewLine+ex.StackTrace);
            }
            finally
            {
                if (driver != null)
                {
                    driver.Close();
                    driver.Quit();
                }
            }
        }

未完.......
