Question

我是Selenium WebDriver的新手。我找到了一些示例代码，并对其进行了一些调整以获得我自己的测试程序。我遇到了麻烦！这是程序：

package test;

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

public class SeleniumTester {
    public static void main(String[] args) {
       try {
           System.setProperty("webdriver.chrome.driver", "C:\\Program Files\\Selenium\\chromedriver.exe");
           WebDriver driver = new ChromeDriver();
           driver.get("http://www.oddsportal.com/");
           driver.manage().window().maximize();
           String str = driver.getCurrentUrl();
           System.out.println("The current URL is " + str);
       }
       catch (Exception ex) { 
           System.out.println("Encountered exception in SeleniumTester.main() :");
           System.out.println(ex.getMessage());
       }
   }
}

编译好，并开始运行，首先输出一些诊断信息：

"Starting ChromeDriver (v2.9.248315) on port 11716
October 25, 2017 6:11:22 IP. 
org.openqa.selenium.remote.ProtocolHandshake createSession
INFO: Detected dialect: OSS"

但是，在＃34; driver.get（...）;＆＃34;发生异常：

"Encountered exception in SeleniumTester.main() :
unknown error: Runtime.executionContextCreated has invalid 'context': {"auxData":{"frameId":"8164.1","isDefault":true},"id":1,"name":"","origin":"://"}

关于无效上下文的事情。这是什么意思？怎么解决？我是否应该使用不同的构造函数来创建ChromeDriver？想法，任何人？

最有可能的问题是因为chromedriver的旧版本。下载更新版本的chromedriver并尝试提供其路径。

浏览器版本和驱动程序版本兼容性问题可能会导致此问题。 chromedriver page提到了浏览器版本的驱动程序兼容性。例如，截至目前，该页面列出了：

最新发布：ChromeDriver 2.33 支持Chrome v60-62

Selenium WebDriver / NetBeans 8.1 / JDK1.8.0异常ChromeDriver Runtime.executionContextCreated具有无效的＆＃39; context＆＃39; ＆＃34;
