对不同的 ChromeDriver 实例使用相同的 Chrome 配置文件(会话)

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
    }
}
}

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

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

好的，所以我正在使用如上所述的方法。

我的要求是：

• 我必须保留主要铬配置文件的饼干
• 我必须保留主配置文件的扩展名
• 我不需要主配置文件的历史记录，打开的选项卡，会话等
• 在现有自定义配置文件重新开始后 - 我在没有打开选项卡的情况下开始它

这是几句话的逻辑。

• 首先，我为现有的谷歌浏览器配置文件指定一个目录。
• 如果我们需要创建cookie（即登录某个网站），那么我们会在谷歌浏览器的主配置文件上执行此操作。
• 完成后，关闭镶边。有些网站会保留很长时间的 cookie，有些 - 不会。因此，在必要时重新登录主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。此文件夹是我们包含所有 cookie 的新配置文件。在我的电脑上，所有东西的大小都在 30 兆字节左右。
• 如果新配置文件的文件夹已经存在 - 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。您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 - 拨打以下电话：

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

对不起，答案很长。希望它以某种方式帮助你们:)
