org.openqa.selenium.firefox.NotConnectedException:使用GeckoDriver和Firefox执行代码时无法连接到主机127.0.0.1 [英] org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 while executing code using GeckoDriver and Firefox

问题描述

代码试用:

public class loginmethod { 

    @Test 
    public void login() throws InterruptedException { 
        System.setProperty("webdriver.gecko.driver", "D:\\Tools\\geckodriver"); 
        WebDriver driver = new FirefoxDriver(); 
        driver.manage().window().maximize(); 
        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
    }
}

二进制版本详细信息:

• FireFox:60.0
• 硒罐:2.45
• GeckoDriver:20.1

当我使用Firefox驱动程序运行代码时，出现以下错误:

When I run code using Firefox driver following error is given:

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

推荐答案

此错误消息...

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:
 Potential driver version mismatch ignored due to missing DLLs igd10umd64 v= and igd10iumd64 v=
*** Blocklist::_preloadBlocklistFile: blocklist is disabled

...表示GeckoDriver无法成功启动/产生新的Web客户端会话/实例.

...implies that the GeckoDriver was unable to initiate/spawn a new Web Client session/instance successfully.

您的主要问题是所使用的二进制文件之间的版本兼容性:

Your main issue is the version compatibility between the binaries you are using as follows :

• 您的 Selenium Client 版本是 2.45 ，这几乎是 2.5年.
• 您的 GeckoDriver 版本是 v20.1 .
• 0.19.0(2017-09-16)的发行说明明确提到以下内容:

• Your Selenium Client version is 2.45 which is almost 2.5 years older.
• Your GeckoDriver version is v20.1.
• Release Notes of 0.19.0 (2017-09-16) clearly mentions the following :

请注意，对于geckodriver 0.19.0，建议使用以下版本:

Note that with geckodriver 0.19.0 the following versions are recommended:

• Firefox 55.0(及更高版本)
• 硒3.5(及更高版本)

• Firefox 55.0 (and greater)
• Selenium 3.5 (and greater)

• 0.16.0(2017-04-21)的发行说明明确提到以下内容:
• Release Notes of 0.16.0 (2017-04-21) clearly mentions the following :

请注意，geckodriver v0.16.0仅与 Selenium 3.4 及更高版本兼容.

• 您的 Firefox 版本是 v60.0 .
• Your Firefox version is v60.0.

因此 Selenium Client v2.45 ， GeckoDriver v20.1 和 Firefox v60.0 之间显然不匹配.

So there is a clear mismatch between Selenium Client v2.45, GeckoDriver v20.1 and Firefox v60.0.

• 将 JDK 升级到最新级别 JDK 8u162 .
• 将硒升级到当前级别> 版本3.11.0 > .
• 将 GeckoDriver 升级到 GeckoDriver v0.20.1 级.
• GeckoDriver位于指定位置.
• GeckoDriver对非root用户具有可执行权限.
• 将 Firefox 版本升级到 Firefox v60.0 级别.
通过 IDE
• 清理您的项目工作区和重建您的项目，并且仅具有必需的依赖项.
• 使用 CCleaner 工具清除之前和之后的所有操作系统杂项在您执行 Test Suite 之后.
• 如果您的基本 Web客户端版本太旧，请通过来卸载. Revo Uninstaller 并安装最新版本的 Web客户端 GA和发行版.
• 进行系统重启.
• 以非root用户身份执行Test.
• 始终在tearDown(){}方法中调用driver.quit()以关闭&优雅地销毁 WebDriver 和 Web Client 实例.
• Upgrade JDK to recent levels JDK 8u162.
• Upgrade Selenium to current levels Version 3.11.0.
• Upgrade GeckoDriver to GeckoDriver v0.20.1 level.
• GeckoDriver is present in the specified location.
• GeckoDriver is having executable permission for non-root users.
• Upgrade Firefox version to Firefox v60.0 levels.
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite.
• If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
• Take a System Reboot.
• Execute your Test as a non-root user.
• Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
