本文介绍了使用不同的ChromeDriver实例相同的镀铬轮廓(会话)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我想并行打开多个浏览器,但我不能浏览该网站在多个窗口。

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

下面是我如何做到这一点:

Here is how I do it:

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
    }
}
}

调用它,因为这:

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,后打开第二个窗口 - 超时错误是shownn:

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

型的第一个机会异常'OpenQA.Selenium.WebDriverException'
发生在WebDriver.dll

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

附加信息:HTTP请求的URL为HTTP远程的webdriver
服务器:/ loca1host:50148 /会话后,60 $超时; b $ b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:

司机=新ChromeDriver(driverService,期权);

driver = new ChromeDriver(driverService, options);

重新运行使用不同的参数测试后,我发现了错误是由于显示在指定的Chrome个人资料:

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");

如果我删除行 - 那么我所有的饼干将不会在ChromeDriver情况下使用,这是不是,我可以:)
住有一种使用在多个chromedriver实例相同的镀铬轮廓的方法是什么?

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

好了,所以我用我的方法如前所述

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

我的要求是:


  • 我必须保持主要的镀铬轮廓的饼干

  • 我必须保持主配置文件的扩展名

  • 我不需要历史上,现有的自定义配置文件的一个新的开始后,打开的标签页,主配置文件

  • 的会议等等 - 我开始清楚没有打开的标签

  • I must keep the cookies of the main chrome profile
  • I must keep extensions of the main profile
  • I do not need the history, opened tabs, session etc. of the main profile
  • after a new start of an existing custom profile - i start it clear without opened tabs

下面是几句话的逻辑。


  • 首先,我指定一个目录现有的谷歌浏览器的配置文件。

  • 如果我们需要创建的cookie(即登录到某网站),那么我们做它在谷歌浏览器的主要轮廓。

  • 它完成后,关闭浏览器。有些网站的Cookie保持很长一段时间,一些 - 不是。因此,它是符合我们的利益的主要轮廓重新登录,如果必要。不要保留原有的镀铬开了!否则ChromeDriver会抛出一些警告。

  • 接下来,我的脚本将必需的文件夹和文件复制到新文件夹。此文件夹是我们与所有的cookies新的配置文件。一切都是关于 30兆字节在我的电脑上尺寸

  • 如果新配置文件的文件夹已经存在 - 那么程序只会复制饼干文件。这是不应该超过 1-2兆数据。

  • 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.

和这里是代码。你可能需要调整一件事或另一个

                }
            }
        }

        public bool PassFileOrFolder(string input, List<string> library)
        {
            foreach (string name in library)
            {
                if (input.Contains(name))
                {
                    return true;
                }
            }
            return false;
        }
    }
}

请注意,我也有实施清理所有配置的方法 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 - 做下面的调用:

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



对不起了很长的答案。希望它可以帮助你们莫名其妙:)
