使用C#Selenium Webdriver正确连接到现有的chrome驱动程序

Question

我使用了Tarun Lalwani设计的方法，通过重用C#中的url和sessionID来附加Selenium Chrome驱动程序。此附加部分起作用，但一些驱动程序方法，如FindElement(By ID(显示错误"strong>"；无效参数：无效定位器(会话信息：chrome＝91.0.4472.114("在线：

var respBase = base.Execute(driverCommandToExecute, parameters);

我的猜测是，这是由于选项或所需的功能在连接驱动程序时为空。但我还没有找到在ReuseRemoteWebDriver上正确设置它的方法。我附上了一张所附驱动程序外观的图片在这里我如何解决这个问题，以便连接以前的chrome驱动程序并保留所有预期的硒功能？

static void Main(string[] args)
{
InputSimulator teclado = new InputSimulator();
ChromeOptions options = new ChromeOptions();
options.UseSpecCompliantProtocol = true;
ChromeDriverService service = ChromeDriverService.CreateDefaultService(@"Thepathofchromedriver");
IWebDriver driver;
DesiredCapabilities capabilities = new DesiredCapabilities();
Uri myUri = new Uri("http://127.0.0.1:65431", UriKind.Absolute);
service.Port = 65431;
string ID = "1f42d5f0ad105910e8d2fc7be23480a9";
if (ID != "")
{

IWebDriver drivertest1 = new ChromeDriver(service, options);

IWebDriver drivertest = new ReuseRemoteWebDriver(myUri, ID,capabilities,options);
driver = drivertest;
}
else
{
IWebDriver drivertest = new ChromeDriver(service,options);

driver = drivertest;

}
IWebElement inputUser = driver.FindElement(By.Id("ID"));}

public class ReuseRemoteWebDriver : OpenQA.Selenium.Remote.RemoteWebDriver
{
private String _sessionId;

public ReuseRemoteWebDriver(Uri remoteAddress, String sessionId, OpenQA.Selenium.Remote.DesiredCapabilities capability, ChromeOptions options)
: base(remoteAddress,options)
{
this._sessionId = sessionId;
var sessionIdBase = this.GetType()
.BaseType
.GetField("sessionId",
System.Reflection.BindingFlags.Instance |
System.Reflection.BindingFlags.NonPublic);
sessionIdBase.SetValue(this, new OpenQA.Selenium.Remote.SessionId(sessionId));

}
protected override OpenQA.Selenium.Remote.Response
Execute(string driverCommandToExecute, System.Collections.Generic.Dictionary<string, object> parameters)
{
if (driverCommandToExecute == OpenQA.Selenium.Remote.DriverCommand.NewSession)
{
var resp = new OpenQA.Selenium.Remote.Response();
resp.Status = OpenQA.Selenium.WebDriverResult.Success;
resp.SessionId = this._sessionId;
resp.Value = new System.Collections.Generic.Dictionary<String, Object>();
return resp;
}
var respBase = base.Execute(driverCommandToExecute, parameters);
return respBase;
}
}

更新：正如我在回复中指出的，我可以解决大多数问题。我无法恢复的最重要的功能是使用注入js脚本

IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
var script = "your script";
js.ExecuteScript(script);

任何关于如何恢复注入脚本功能的想法都将不胜感激。

如果有人感兴趣，我修改了前面的类如下，这样我就可以使用sendKeysToElement

public class ReuseRemoteWebDriver : OpenQA.Selenium.Remote.RemoteWebDriver
{
private String _sessionId;
public ReuseRemoteWebDriver(Uri remoteAddress, String sessionId, ChromeOptions options, ChromeDriverService service)
: base(remoteAddress, options)
{
//object x = driver;
this._sessionId = sessionId;
var sessionIdBase = this.GetType()
.BaseType
.GetField("sessionId",
System.Reflection.BindingFlags.Instance |
System.Reflection.BindingFlags.NonPublic);

//System.Collections.Generic.Dictionary<string, object> x = this.GetCapabilitiesDictionary(capability);

sessionIdBase.SetValue(this, new OpenQA.Selenium.Remote.SessionId(sessionId));

}
protected override OpenQA.Selenium.Remote.Response
Execute(string driverCommandToExecute, System.Collections.Generic.Dictionary<string, object> parameters)
{
if (driverCommandToExecute == OpenQA.Selenium.Remote.DriverCommand.NewSession)
{
var resp = new OpenQA.Selenium.Remote.Response();
resp.Status = OpenQA.Selenium.WebDriverResult.Success;
resp.SessionId = this._sessionId;
resp.Value = new System.Collections.Generic.Dictionary<String, Object>();
return resp;
}
if (driverCommandToExecute == "sendKeysToElement")
{
object[] array = (object[])parameters["value"];
string stringfinal = (string)array[0].ToString();

parameters.Add("text", stringfinal);
}
if (driverCommandToExecute == "executeScript")
{
Console.WriteLine("");
}
var respBase = base.Execute(driverCommandToExecute, parameters);
return respBase;
}
}
}

在其他类中，我使用了以下方法来正确使用Selenium等待。

public Boolean WaitInteligente(WebDriverWait wait, string condition, By selector = null, 
IWebElement optionalWebElement = null,string optionalstring = null,
bool optionalbool = false,bool devolverexcepcion=true )
{
TimeSpan Tiempo = wait.Timeout;
var globalclock = Stopwatch.StartNew();
Boolean stop = false;
double segundos = globalclock.Elapsed.TotalSeconds;
Exception exception = null;
//globalclock.Stop();
while (segundos <= Tiempo.TotalSeconds)
{
Thread.Sleep(500);
try
{
segundos = globalclock.Elapsed.TotalSeconds;
if (condition == "ElementExists")
wait.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.ElementExists(selector));
if (condition == "ElementIsVisible")
wait.Until(ExpectedConditions.ElementIsVisible(selector));
if (condition == "ElementToBeClickable")
wait.Until(ExpectedConditions.ElementToBeClickable(selector));
if (condition == "ElementToBeSelected")
wait.Until(ExpectedConditions.ElementToBeSelected(selector));
if (condition == "FrameToBeAvailableAndSwitchToIt")
wait.Until(ExpectedConditions.FrameToBeAvailableAndSwitchToIt(selector));
if (condition == "InvisibilityOfElementLocated")
wait.Until(ExpectedConditions.InvisibilityOfElementLocated(selector));
if (condition == "PresenceOfAllElementsLocatedBy")
wait.Until(ExpectedConditions.PresenceOfAllElementsLocatedBy(selector));
if (condition == "VisibilityOfAllElementsLocatedBy")
wait.Until(ExpectedConditions.VisibilityOfAllElementsLocatedBy(selector));
if (condition == "AlertIsPresent")
wait.Until(ExpectedConditions.AlertIsPresent());
if (condition == "ElementToBeSelected")
wait.Until(ExpectedConditions.ElementToBeSelected(optionalWebElement));
if (condition == "InvisibilityOfElementWithText")
wait.Until(ExpectedConditions.InvisibilityOfElementWithText(selector,optionalstring));
if (condition == "StalenessOf")
wait.Until(ExpectedConditions.StalenessOf(optionalWebElement));
if (condition == "TextToBePresentInElement")
wait.Until(ExpectedConditions.TextToBePresentInElement(optionalWebElement,optionalstring));
if (condition == "TextToBePresentInElementLocated")
wait.Until(ExpectedConditions.TextToBePresentInElementLocated(selector, optionalstring));
if (condition == "TextToBePresentInElementValue")
wait.Until(ExpectedConditions.TextToBePresentInElementValue(selector, optionalstring));
if (condition == "TitleContains")
wait.Until(ExpectedConditions.TitleContains(optionalstring));
if (condition == "TitleIs")
wait.Until(ExpectedConditions.TitleIs(optionalstring));
if (condition == "UrlContains")
wait.Until(ExpectedConditions.UrlContains(optionalstring));
if (condition == "UrlMatches")
wait.Until(ExpectedConditions.UrlMatches(optionalstring));
if (condition == "UrlToBe")
wait.Until(ExpectedConditions.UrlToBe(optionalstring));
if (condition == "FrameToBeAvailableAndSwitchToIt")
wait.Until(ExpectedConditions.FrameToBeAvailableAndSwitchToIt(optionalstring));
if (condition == "AlertState")
wait.Until(ExpectedConditions.AlertState(optionalbool));
if (condition == "ElementSelectionStateToBe")
wait.Until(ExpectedConditions.ElementSelectionStateToBe(selector,optionalbool));
if (condition == "ElementSelectionStateToBe")
wait.Until(ExpectedConditions.ElementSelectionStateToBe(selector, optionalbool));

stop = true;
break;
}
catch (Exception e)
{
e = new Exception(selector.ToString() + condition + e.Message);
exception = e;
}
}
if (!stop && devolverexcepcion)
throw exception;
return stop;
}

附加时无法正常工作的方法有驾驶员FindElement(按.Id(和驱动程序。FindElement(By.ClassName(，可以通过分别对ID或类名使用By.CssSelector调用来轻松规避。

我无法恢复的最重要的功能是使用注入js脚本

IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
var script = "your script";
js.ExecuteScript(script);
