C# Selenium Webdriver 异常 |此版本的 ChromeDriver 仅支持 Chrome 版本 85

Question

MyChromeDriver

我的谷歌浏览器版本：88.0.4324.150

我找到了一些解决方案，但它们对我不起作用。 我想打开 Google Chrome 并抛出 Selenium，但它还不起作用。

错误

代码

System.Environment.SetEnvironmentVariable("webdriver.chrome.driver", @"C:\Program Files\Google\Chrome\Application\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.AddArguments("start-maximized");
options.AddArguments("disable-infobars");
options.AddArguments("--disable-extensions");
options.AddArguments("--disable-gpu");
options.AddArguments("--disable-dev-shm-usage");
options.AddArguments("--no-sandbox");
IWebDriver driver = new ChromeDriver(options);

Answer 1

http://chromedriver.chromium.org/downloads?tmpl=%2Fsystem%2Fapp%2Ftemplates%2Fprint%2F&showPrintDialog=1

从这里下载 chrome 驱动程序 88

https://www.selenium.dev/selenium/docs/api/dotnet/html/T_OpenQA_Selenium_Chrome_ChromeDriver.htm

你可以看到构造函数接受可执行文件的路径

所以使用

IWebDriver driver = new ChromeDriver("c:/DownloadeddirectoryPath",options);

注意：路径应该是包含 chromedriver.exe 的目录的 PATH，而不是 chromedriver.exe 本身

Answer 2

确保 webdriver 和 Chrome（实际上我建议 Chromium）版本相同的另一种方法是从同一个 Chromium 快照页面下载两者。 https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html

例如，v96 Chromium Linux 和相应的 Web 驱动程序位于此处： https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Linux_x64/929513/

稳定版本的内部版本号可以在这里找到：https://github.com/Bugazelle/chromium-all-old-stable-versions

PDHide 已经描述了如何指向 webdriver 路径。要指向 Chromium 二进制文件/可执行文件，请使用

var options = new ChromeOptions();
options.BinaryLocation = "/full/location/including/binary";
var driver = new ChromeDriver("/folder/where/webdriver/located", options);

Answer 3

@PDHide 的解决方案解决了我的问题，但我又遇到了同样的问题。 我现在已经这样解决了：

我已将 Nuget 中的 WebDriverManager 添加到我的项目中。 我已将这一行添加到 onload：

new DriverManager().SetUpDriver(new ChromeConfig(), VersionResolveStrategy.MatchingBrowser);

我创建了一个返回 WebDriver 对象的方法：

 public IWebDriver GetChromeDriver()
 {
     ChromeOptions options = new ChromeOptions();
     options.AddArgument("no-sandbox");
     string[] files = Directory.GetFiles(AppDomain.CurrentDomain.BaseDirectory + "/Chrome", "ChromeDriver.exe", SearchOption.AllDirectories);
     List<KeyValuePair<string, DateTime>> lstFile = new List<KeyValuePair<string, DateTime>>();
     foreach (string file in files)
     {
         lstFile.Add(new KeyValuePair<string, DateTime>(file, File.GetLastWriteTime(file)));
     }
     string filePath = System.IO.Path.GetDirectoryName(lstFile.OrderByDescending(r => r.Value).First().Key);
     return new ChromeDriver(filePath, options);
 }

 

我这样称呼它：

IWebDriver myDriverChrome = new BasicOperations().GetChromeDriver();
