OpenQA.Selenium.WebDriverException Message=無法在 http://localhost:port/ 上通過 C# 中的 Selenium 使用 ChromeDriver Chrome 啟動驅動程序服務

Question

我正在使用最新的 Selenium.WebDriver NuGet 包 v3.141.0

最新的 Selenium.WebDriver.ChromeDriver 包 v80.0.3987.1600

我的 chrome 版本是 80.0.3987.87

chromedriver.exe 與我的程序可執行文件位於同一文件夾中

var driver = new ChromeDriver();
driver.Navigate().GoToUrl("https://www.google.com/");

Starting ChromeDriver 80.0.3987.16 (320f6526c1632ad4f205ebce69b99a062ed78647-refs/branch-heads/3987@{#185}) on port #
Only local connections are allowed.

其次是整個堆棧跟蹤 -

OpenQA.Selenium.WebDriverException

編輯：我也試過

IWebDriver driver;
            using (driver = new ChromeDriver())
            {
                driver.Navigate().GoToUrl(@"https://www.google.com/");
            }

失敗並出現相同的錯誤並嘗試了 IE 和 Firefox 驅動程序

更新：

所以我在家里（不是在我公司的網絡上）嘗試了這個，它使用了這個確切的代碼......我被防火牆阻止了嗎？

Answer 1

您必須注意以下幾點：

• 您需要傳遞整個url ，即將www添加到https://google.com ，因此有效的url將是https://www.google.com/ 。
• 此外，由於您已將ChromeDriver的實例初始化為driver ，因此您必須僅使用驅動程序實例調用Navigate() ，而不是使用drive 。

• 實際上，您的代碼塊將是：

   var driver = new ChromeDriver(); driver.Navigate().GoToUrl("https://www.google.com/");
