获取IE驱动程序的org.openqa.selenium.remote.SessionNotFoundException

Question

我收到org.openqa.selenium.remote.SessionNotFoundException：尝试通过IE驱动程序打开google.com时，会话null不存在异常。

我的代码如下：

public class Google {
    static WebDriver obj;

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        String browser = "ie";

        if (browser.equalsIgnoreCase("chrome")) {
            System.setProperty("webdriver.chrome.driver", "E:\\Selenium\\Selenium Prerequisites\\chromedriver.exe");
            obj = new ChromeDriver();

        } else if (browser.equalsIgnoreCase("firefox")) {
            obj = new FirefoxDriver();
        } 
        else if (browser.equalsIgnoreCase("ie")){
            System.setProperty("webdriver.ie.driver", "E:\\Selenium\\Selenium Prerequisites\\IEDriverServer.exe");
            obj = new InternetExplorerDriver();

        }
        else
            System.out.println("invalid browser name");

        obj.get("https:\\google.com");
    }
}

请告诉我我失踪的地方，我使用的是IE浏览器v11，selenium webdriver v2.53.1，IEDriverServer v3.6.0 32位。

以下是完整的例外我正在（请注意，如果我切换到selenium webdriver v3.6，那么没有问题，代码工作正常）：

感谢。

Answer 1

手动执行

为所有区域设置相同的安全级别。尝试这个步骤

• 打开Internet Explorer浏览器
• 转到菜单并打开工具 - ＆gt;互联网选项 - ＆gt;安全
• 将区域的所有值（Internet，本地Intranet，受信任的站点，受限制的站点）设置为相同的保护模式，启用或禁用无关紧要
• 点击OK。

或使用此

DesiredCapabilities IEcaps = DesiredCapabilities.internetExplorer();

IEcaps .setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS,true);

WebDriver driver = new InternetExplorerDriver(IEcaps );

Answer 2

除了为所有4个区域设置启用或禁用保护模式外，您还需要在Internet Explorer中将缩放级别设置为100％。

Answer 3

要使用$userdb=[ ["uid"=> '100', "name" => 'Sandra Shush',"url"=> 'urlof100'], ["uid"=> '5465', "name" => 'Sandra Shush',"url"=> 'urlof100'], ["uid"=> '100', "name" => 'Sandra Shush',"url"=> 'urlof100'], ["uid"=> '5465', "name" => 'Sandra Shush',"url"=> 'urlof100']]; foreach($userdb as $value) { $result[$value['uid']][] = $value; } print_r(array_values($result)); 启动 Array ( [0] => Array ( [0] => Array ( [uid] => 100 [name] => Sandra Shush [url] => urlof100 ) [1] => Array ( [uid] => 100 [name] => Sandra Shush [url] => urlof100 ) ) [1] => Array ( [0] => Array ( [uid] => 5465 [name] => Sandra Shush [url] => urlof100 ) [1] => Array ( [uid] => 5465 [name] => Sandra Shush [url] => urlof100 ) ) ) ，请使用IE11版本和最新的selenium WebDriver。它适用于IE11 您可以在以下链接中获取IE驱动程序3.4.0 http://selenium-release.storage.googleapis.com/index.html?path=3.4/

还将以下代码段添加到您的代码中，以忽略IE的保护模式设置，并在代码中设置IEDriverServer_Win32_3.4.0的路径
