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?
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:
这是几句话的逻辑.

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 :)
这篇关于对不同的 ChromeDriver 实例使用相同的 chrome 配置文件(会话)的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持跟版网！
