C＃将Selenium与Chrome Portable和driver.Navigate（）。GoToUrl结合使用

Question

What I am trying to accomplish is, I think, relatively simple. I am trying to write code that will use a Google Chrome Portable executable and also execute selenium powered web-page element finding and selecting using the latest version of the chrome driver. Currently, I know how to do one or the other, but not both.

The following code will open Google Chrome from it's standard installation location (C:Program Files (x86) and input the text for "Polar Bears" in the Google Search box.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
using System.Threading;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Support.UI;

namespace LaunchChrome
{
    class GoogleInquiry
    {
        static void Main(string[] args)
        {
            //Start Chrome Driver Service from Custom Location
                ChromeDriverService service = ChromeDriverService.CreateDefaultService(@"C:\GoogleSearch");

            //Force the CMD prompt window to automatically close and suppress diagnostic information
                service.HideCommandPromptWindow = true;
                service.SuppressInitialDiagnosticInformation = true;

            //Setup Chrome to utilize custom options
                var options = new ChromeOptions();

            //Google Chrome Custom Options
                options.AddArgument("disable-infobars");
                options.AddArgument("--silent");

            // Assign driver variable to Chrome Driver            
            var driver = new ChromeDriver(service, options);

            //Navigate to the Google website
                driver.Navigate().GoToUrl("https://www.google.com");

            //Automate custom Google Search Submission
                driver.FindElement(By.Name("q")).SendKeys("Polar Bears");

        }
    }
}

But, when I use the custom chrome location binary option given below, than it will open Google Chrome Portable, but it won't go to google.com. Rather, the URL will say simply "data:," and the code will timeout in visual studio with this message:

"OpenQA.Selenium.WebDriverException: 'The HTTP request to the remote WebDriver server for URL http://localhost:59127/session timed out after 60 seconds.'

options.BinaryLocation = @"C:\GoogleChromePortable\GoogleChromePortable.exe";

I have tried using the chromium flag for new window (-- new-window + URL) and using the app flag (--app +URL) but both fail to run the code that should go to google and input "Polar Bears" in the search box.

Assistance would be appreciated.

Thank you very much.

For Specs, I am using the following:

• Windows 7
• Visual Studio Community Edition 2017
• Google Chrome Portable 68 (Also tried older versions of Chrome portable)
• Chrome Driver 2.40 (also tried 2.41)

Answer 1

As per your question and code attempts I don't see any any major flaw. Perhaps as per other discussions options.BinaryLocation must point to the absolute location of the portable chrome binary as follows:

options.BinaryLocation = @"C:\\GoogleChromePortable\\chrome.exe";

Answer 2

You should use the other chrome.exe location the one which is inside Chrome-bin folder

String seStandAloneServerUrl = @"the stand alone server url here";
var cOptions = new ChromeOptions();
cOptions.BinaryLocation = @"C:\GoogleChromePortable\App\Chrome-bin\chrome.exe";
driver = new RemoteWebDriver(new Uri(seStandAloneServerUrl), cOptions);
