UnhandledAlertException尽管在Selenium / Chrome中取消了警报

标签: c# selenium-chromedriver unhandled-exception

我在C#中将Selenium与Chromedriver结合使用:

<packages>
  <package id="Selenium.Chrome.WebDriver" version="2.42" targetFramework="net461" />
  <package id="Selenium.WebDriver" version="3.14.0" targetFramework="net461" />
</packages>

打开包含警报的网页时,我总是会遇到异常:

unexpected alert open: {Alert text : muh}
  (Session info: chrome=69.0.3497.100)
  (Driver info: chromedriver=2.42.591088 (7b2b2dca23cca0862f674758c9a3933e685c27d5),platform=Windows NT 10.0.17134 x86_64)

示例代码:

static void Main(string[] args) {

            ChromeOptions options = new ChromeOptions();
            options.UnhandledPromptBehavior = UnhandledPromptBehavior.Dismiss;

            using (var browser = new ChromeDriver(options)) {
                browser.Navigate().GoToUrl(@"D:\downloads\test.html");
                Console.WriteLine(browser.PageSource); //Exception happens here
            }

            Console.WriteLine("done");
            Console.ReadLine();
}

示例HTML:

<!doctype html>
<html>
<head>
</head>
<body>
<script>
alert("muh");
document.write("<p>blah</p>");
</script>
</body>
</html>

看来options.UnhandledPromptBehavior = UnhandledPromptBehavior.Dismiss没什么区别。我应该怎么做才能防止这种情况发生?

尝试通过try / catch解决问题:

try
{
  Console.WriteLine(browser.PageSource); //Exception happens here
}
catch (UnhandledAlertException unhandledAlertException)
{
   // ignore exception or put the rest of the code
}
