问题描述

我正在尝试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..

I am trying to open multiple browsers in parallel, but I can not navigate to the website in more than one window..

这是我的做法:

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
    }
}
}

这样称呼它:

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，打开第二个窗口后 - 显示超时错误:

Unfortunately, after the second window is opened - timeout error is shownn:

OpenQA.Selenium.WebDriverException"类型的第一次机会异常发生在 WebDriver.dll 中

A first chance exception of type 'OpenQA.Selenium.WebDriverException' occurred in WebDriver.dll

附加信息:对远程 WebDriver 的 HTTP 请求URL http:/loca1host:50148/session 的服务器在 60 后超时秒.

Additional information: The HTTP request to the remote WebDriver server for URL http:/loca1host:50148/session timed out after 60 seconds.

在这一行:

driver = new ChromeDriver(driverService, options);

driver = new ChromeDriver(driverService, options);

使用不同的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:

after rerunning the test with different parameters I have found out that the error is shown due to the specified Chrome profile:

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，这不是我可以忍受的:)有没有办法在多个 chromedriver 实例中使用相同的 chrome 配置文件?

If I remove the line - then all of my cookies will not be used in ChromeDriver instance and that is not something that I can live with :) Is there a way to use the same chrome profile in multiple chromedriver instances?

推荐答案

好的，所以我正在使用上述方法.

Okay, so I am using my approach as stated above.

我的要求是:

• 我必须保留主要 chrome 配置文件的 cookie
• 我必须保留主要配置文件的扩展名
• 我不需要主配置文件的历史记录、打开的选项卡、会话等
• 在重新启动现有自定义配置文件后 - 我在没有打开标签的情况下清楚地启动它

这是几句话的逻辑.

• 首先我为现有的 Google Chrome 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 google chrome 的主配置文件中进行.
• 完成后，关闭 chrome.有些网站会保留 cookie 很长时间，有些则不会.因此，在必要时重新登录主配置文件符合我们的利益.不要让原始铬打开！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 PC 上，所有内容的大小约为 30 兆字节.
• 如果新配置文件的文件夹已经存在 - 那么程序将只复制 cookie 文件.这不应超过 1-2 兆 的数据.

• First I specify a directory for the existing Google Chrome profile.
• If we need to create cookies (i.e. login into some website) then we do it on the main profile of google chrome.
• After it is done, close the chrome. Some websites keep cookies for a long time, some - not. So it is in our interest to relogin on the main profile when necessary. Do not keep the Original chrome opened! Otherwise ChromeDriver will throw some warnings.
• Next, my script will copy the necessary folders and files into new folder. This folder is our new profile with all cookies. Everything is about 30 megabytes in size on my PC.
• If the folder for the new profile already exists - then the program will only copy cookies files. That's shouldn't be more than 1-2 megs of data.

这是代码.您可能想要调整一件事或另一件事.

        }
    }
}

请注意，我还实现了一种清理所有配置文件的方法CleanUpOldProfiles

Please note that I have also implemented a method to clean up all profiles CleanUpOldProfiles

查看代码，更改目录等.完成后 - 进行以下调用:

Review the code, make changes to directories etc. After done - make a following call:

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:)

sorry for a long answer. Hope it helps you guys somehow :)
