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..
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
}
}
}
将其称为：
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：
“OpenQA.Selenium.WebDriverException”类型的第一次机会异常 发生在WebDriver.dll
中其他信息：对远程WebDriver的HTTP请求 URL http：/ loca1host：50148 / session的服务器在60之后超时 秒。
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，这不是我可以忍受的东西:) 有没有办法在多个chromedriver实例中使用相同的chrome配置文件？
答案 0 :(得分：9)
好的，我正在使用上述方法。
我的要求是：
这是几句话中的逻辑。
这是代码。你可能想要调整一件事或另一件事。

请注意，我还实施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
