问题：

无法在selenium webdriver上启动新会话

崔棋
2023-03-14

我正在尝试使用selenium java代码打开firefox浏览器。

System.setProperty("webdriver.gecko.driver", "  System.setProperty("webdriver.gecko.driver", "C:/Program Files/Mozilla Firefox/geckodriver-v0.8.0-win32/geckodriver.exe");

WebDriver driver = new FirefoxDriver();
System.setProperty("webdriver.firefox.port","4444");

Selenium服务器已启动并正在运行。我尝试使用命令提示符更改selenium服务器端口，并在代码中设置端口，但两者都不起作用。

在错误消息“连接到localhost:6544”中，它每次都试图连接到不同的localhost。有人能看出问题出在哪里吗？

我使用的版本有：

  • firefox 48.0

另外，我的geckodriver可执行文件没有运行，它显示为VCRUNTIME140。dill不见了，我应该重新安装来解决这个问题。但在我重新安装之后，同样的事情发生了。

更新

感谢@Saurabh的建议，我将selenium的评级下调至2.53.1。浏览器正在打开，但没有显示任何内容。我又犯了一个错误

首先确保添加的所有jar文件，包括 /lib文件夹中的文件以下代码将打开浏览器，并添加超文本传输协议链接。顺便说一下，我用的是win7 64位，所以要注意geckoDrive路径。

System.setProperty("webdriver.gecko.driver", "C:\\Users\\XYZ\\Documents\\geckodriver.exe");
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);

try {
    WebDriver driver = new FirefoxDriver();
    driver.navigate().to("http://google.com");
} catch(Exception e) {
    System.out.println(e);
}

您需要将desired capabilities与marionette功能传递到true到FirefoxDriver以及以下内容：-

System.setProperty("webdriver.gecko.driver", "C:/Program Files/Mozilla Firefox/geckodriver-v0.8.0-win32/geckodriver.exe");

//Now you can Initialize marionette driver to launch firefox
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new FirefoxDriver(capabilities);

编辑：如果不幸的是上述方法不起作用，我建议您将firefox降级到45或更低，并使用FirefoxDriver，如下所示：-

WebDriver driver = new FirefoxDriver();
