OpenQA.Selenium.WebDriverException

Question

嗨，我有一個 c# window 表單應用程序，它在工作之前使用 selenium 打開邊緣，但幾個月后我收到此錯誤

An unhandled exception of type 'OpenQA.Selenium.WebDriverException' occurred in WebDriver.dll

Additional information: A exception with a null response was thrown sending an HTTP request to the remote WebDriver server for URL http://localhost:53335/session. The status of the exception was ReceiveFailure, and the message was: The underlying connection was closed: An unexpected error occurred on a receive.

這是堆棧跟蹤

我使用 Selenium webdriver - v 3.141.0 selenium webdriver IE v 3.141.0

這是我的代碼

   var driverService = EdgeDriverService.CreateDefaultService();

                    EdgeOptions options = new EdgeOptions();                 
                    //var driver = new EdgeDriver(driverService);
                    edgeDriver = new EdgeDriver(driverService);


                    edgeDriver.Navigate().GoToUrl(Config.SpcUrl);

Answer 1

對於 Microsoft Edge 42.17134.1.0，MicrosoftEdge HTML 17.17134。

您可以從此鏈接下載 Release 17134 版本的 Edge WebDriver。

然后使用以下代碼使用 webDriver（將驅動程序路徑更改為您自己的）：

 using OpenQA.Selenium;
 using OpenQA.Selenium.Edge;

namespace ecwebdriver
{
    public class edgewebdriver
    {
        static void Main(string[] args)
        {
            var driverpath = @"C:\Windows\System32"; 
            using (var driver = new EdgeDriver(driverpath))
            {
                // Navigate to Bing
                driver.Url = "https://www.bing.com/"; 
                // Find the search box and query for webdriver
                var element = driver.FindElementById("sb_form_q");

                element.SendKeys("webdriver");
                element.SendKeys(Keys.Enter);
                driver.Quit();
            }
       }
    }
}

對於 Edge Chromium 版本（81.0.416.72（官方構建）（64 位））

從這里下載 Selenium 4.00-alpha05 的 C# 綁定或通過 Nuget ZEFE470A8E603AE877C8安裝它

從此頁面下載 Microsoft Edge 驅動程序的匹配版本。

然后，使用以下代碼（將驅動程序路徑和網站 url 更改為您自己的）：

using OpenQA.Selenium.Edge;
using System.Threading;

namespace ecwebdriver
{
    public class edgewebdriver
    {
        static void Main(string[] args)
        {
            EdgeOptions edgeOptions = new EdgeOptions();
            edgeOptions.UseChromium = true;
            edgeOptions.BinaryLocation = @"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe"; 

            var msedgedriverDir = @"E:\webdriver";
            var driver = new EdgeDriver(msedgedriverDir, edgeOptions); 
            driver.Navigate().GoToUrl("<website url>");
            Thread.Sleep(3000);
            driver.Close();
        }
    }
}
