org.openqa.selenium.WebDriverException: java.net.ConnectException: 无法使用 IEDriverServer 连接到 localhost 错误

Question

我已经尝试在 webdriver 中启动 IE，如下所示，我检查了 Internet 选项的安全选项卡中的所有保护模式设置，缩放级别为 100%，甚至设置了环境变量，但无法在简单的 selenium 代码中启动 IE 浏览器;尽管给出了 url http://google.co.in 并被视为无法连接到本地主机的错误，并且由以下原因引起：java.net.ConnectException：连接被拒绝：有人可以帮我解决这个问题。提前谢谢你

package eHMS_package;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;

public class EHMS_Login {

    public WebDriver driver;

    public static void main(String[] args)
    {
        System.setProperty("webdriver.ie.driver", "E:/SRIKANTH/IEDriver/IEDriverServer.exe");
        WebDriver driver = new InternetExplorerDriver();
        driver.navigate().to("http://google.co.in");
    }
}

错误说明了一切：

Started InternetExplorerDriver server (64-bit)3.9.0.0 
Exception in thread "main" org.openqa.selenium.WebDriverException: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:48107 
Build info: version: '3.11.0', revision: 'e59cfb3', time: '2018-03-11T20:33:15.31Z' 
System info: host: 'UMANATH-PC', ip: '10.1.0.25', os.name: 'Windows 7', os.arch: 'amd64', os.version: '6.1', java.version: '1.8.0_161' 
Driver info: driver.version: InternetExplorerDriver

从错误堆栈跟踪中可以清楚地看出，InternetExplorerDriver 服务器 没有被检测到，如下所示：

Driver info: driver.version: InternetExplorerDriver

您的主要问题是您使用的二进制文件之间的版本兼容性，如下所示：

• 您正在使用 Selenium Client v3.11.0
• 但您使用的是 InternetExplorerDriverServer v3.9.0.0

因此 Selenium Client v3.11.0 和 InternetExplorerDriverServer v3.9.0.0 之间存在明显的不匹配>.

解决方案

• 升级到 InternetExplorerDriverServer v3.11.1.0
