WebDriverException:未知错误:Runtime.executionContextCreated 具有无效的“上下文":初始化 Chrome 浏览器时

2022-01-15 00:00:00 selenium selenium-chromedriver selenium-webdriver java

我正在尝试开始使用 selenium，并已下载 chrome 驱动程序并放入我的类路径中.我现在只是想获得标题，看看我是否可以让它工作.目前的代码如下所示:

I'm trying to get started using selenium and have downloaded a chrome driver and put into my classpath. I'm just trying to get the title right now to see if I can get it to work. Code currently looks like this:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class Flows {

    public static void main(String[] args) {

        System.setProperty("webdriver.chrome.driver", "/Users/mn/Desktop/project/turv/src/main/chromedriver");
        WebDriver driver = new ChromeDriver();
        String baseUrl = "http://google.dk/";
        driver.get(baseUrl);
        System.out.println(driver.getTitle());
        driver.close();
    }
}

我希望我的输出类似于Google"，但我得到了这个错误:

I expected my output to be something along the lines of "Google", but I get this error instead:

我真的无法弄清楚错误试图告诉我什么.是因为我在网站完全加载之前要求标题吗?我需要在 getTitle() 之前添加某种 waitforit 命令吗?

I cant really figure out what the error is trying to tell me. Is it because I'm asking for the title before it has fully loaded the site maybe? Do I need to add some kind of waitforit command before the getTitle() ?

推荐答案

这个错误信息...

org.openqa.selenium.WebDriverException: unknown error: Runtime.executionContextCreated has invalid 'context': {"auxData":{"frameId":"11895A1B77AC560388AA2919259E1422","isDefault":true},"id":1,"name":"","origin":"://"}

...暗示 ChromeDriver 无法启动/生成新的 WebBrowser 即 Chrome 浏览器 会话.

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

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:

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

  • 您使用的是chromedriver=2.8，它相当古老.
  • 您正在使用 chrome=66.0
  • ChromeDriver v2.38 的发行说明明确提及以下内容:

支持 Chrome v65-67

所以 ChromeDriver 版本 (v2.8) 和 Chrome 浏览器 版本 (v66.0) 之间存在明显的不匹配)

So there is a clear mismatch between ChromeDriver version (v2.8) and the Chrome Browser version (v66.0)

  • 将 ChromeDriver 升级到当前的 ChromeDriver v2.38 级.
  • 将 Chrome 版本保持在 Chrome v66.x 级别.(根据 ChromeDriver v2.38 发行说明)
  • 清理你的项目工作区通过你的IDE和重建你的项目只需要依赖.
  • 使用 CCleaner 工具清除之前和之后的所有操作系统杂务测试套件的执行.
  • 如果您的基础 Web Client 版本太旧，请通过 <卸载它em>Revo Uninstaller 并安装最新的 GA 和发布版本的 Web 客户端.
  • 进行一次系统重启.
  • 执行你的 @Test.
  • 总是在 tearDown(){} 方法中调用 driver.quit() 来关闭 &优雅地销毁 WebDriver 和 Web Client 实例.
  • Upgrade ChromeDriver to current ChromeDriver v2.38 level.
  • Keep Chrome version at Chrome v66.x levels. (as per ChromeDriver v2.38 release notes)
  • 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.
  • Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
