使用带有Selenium Webdriver的Chrome驱动程序时出现SocketException

Question

我正在学习Selenium webdriver，在成功使用firefox后，现在我想尝试启动Chrome。所以我设置了它的驱动程序

System.setProperty("webdriver.chrome.driver","C:\\Users\\user\\OAutomation Test\\browser drivers\\chromedriver.exe");
 WebDriver driver = new ChromeDriver();
 driver.get("http://localhost:7001/mywebapp");

但是当代码流命中driver.get（）指令时，我得到了这个异常：

starting ChromeDriver 2.20.353145 (343b531d31eeb933ec778dbcf7081628a1396067) on port 9520
Only local connections are allowed.

他们建议here使用最新版本的依赖项selenium-java和selenium-chrome-driver，以及最新的Chrome驱动程序可执行文件。他们附加的例外示例显示了与您相同的ChromeDriver 2.20.353145，这似乎是一个应该在较新版本中修复的已知问题。
