为不同的ChromeDriver实例使用相同的chrome配置文件（会话）

我试图并行打开多个浏览器，但我无法在多个窗口中导航到该网站。

我是这样做的：

namespace XXX { public class CoreDriver { public IWebDriver driver; public int my_port { get; set; } public void Initialize() { string chromeee = ""; if (my_port == 50147) { chromeee = "C:/Users/AA/Downloads/chromedriver1/"; } else if (my_port == 50148) {chromeee = "C:/Users/AA/Downloads/chromedriver2/"; } else if (my_port == 50149) { chromeee = "C:/Users/AA/Downloads/chromedriver3/"; } else if (my_port == 50140) { chromeee = "C:/Users/AA/Downloads/chromedriver4/"; } ChromeOptions options = new ChromeOptions(); options.AddArgument("user-data-dir=C:\\Users\\AA\\AppData\\Local\\Google\\Chrome\\User Data"); var driverService = ChromeDriverService.CreateDefaultService(chromeee); driverService.HideCommandPromptWindow = true; driverService.Port = my_port; driver = new ChromeDriver(driverService, options); driver.Manage().Timeouts().ImplicitlyWait(new TimeSpan(0,0,12)); driver.Manage().Timeouts().SetPageLoadTimeout(TimeSpan.FromSeconds(13)); //driver navigate } } } 

称之为：

 CoreDriver A1 = new CoreDriver(); A1.my_port = 50147; A1.Initialize(); CoreDriver A2 = new CoreDriver(); A2.my_port = 50148; A2.Initialize(); // timeout error here // ... 

不幸的是，在第二个窗口打开后 – 显示超时错误：

WebDriver.dll中出现“OpenQA.Selenium.WebDriverException”类型的第一次机会exception

附加信息：远程WebDriver服务器对URL http：/ loca1host：50148 / session的HTTP请求在60秒后超时。

在这一行：

driver = new ChromeDriver（driverService，options）;

在使用不同参数重新运行测试后，我发现由于指定的Chrome配置文件而显示错误：

 options.AddArgument("user-data-dir=C:\\Users\\AA\\AppData\\Local\\Google\\Chrome\\User Data"); 

如果我删除该行 – 那么我的所有Cookie都不会在ChromeDriver实例中使用，而这不是我可以使用的东西:)有没有办法在多个chromedriver实例中使用相同的chrome配置文件？

Answer 1

好的，所以我正在使用我的方法，如上所述。

我的要求是：

• 我必须保留主要铬配置文件的cookie
• 我必须保留主要配置文件的扩展名
• 我不需要主要配置文件的历史记录，打开的标签，会话等
• 在新的现有自定义配置文件启动后 – 我在没有打开标签的情况下开始清除它

这是几句话的逻辑。

• 首先，我指定现有Google Chrome配置文件的目录。
• 如果我们需要创建cookie（即登录某个网站），那么我们在谷歌浏览器的主要配置文件上进行。
• 完成后，关闭铬。 有些网站会长时间保留cookie，有些则不然。 因此，在必要时重新登录主要配置文件符合我们的利益。 不要保持原始镀铬打开！ 否则ChromeDriver会抛出一些警告。
• 接下来，我的脚本会将必要的文件夹和文件复制到新文件夹中。 此文件夹是包含所有Cookie的新配置文件。 在我的电脑上，一切都是大约30兆字节 。
• 如果新配置文件的文件夹已存在 – 则程序将仅复制cookie文件。 这不应该超过1-2兆的数据。

这是代码。 你可能想要调整一件事或另一件事。

请注意，我还实现了一种方法来清理所有配置文件CleanUpOldProfiles

查看代码，更改目录等。完成后 – 进行以下调用：

 CoreDriver something = new CoreDriver(); // creating an object // settings something.my_port = 50150; // multiple chrome instances - will be run on different ports // I am currently having 4 chrome profiles ;) something.my_name = "mynewprofile"; // full profile name will be: 'profile + my_name'. Check the code of the object. // void something.ConfigureProfile(); // creating new profile or updating existing one, if folder eists something.Initialize(); // starting the browser 

抱歉，答案很长。 希望它能以某种方式帮助你们:)
