Question

我尝试使用“Selenium Remote Webdriver”进行自动化测试，但在尝试连接远程服务器时遇到异常。

例外情况是：

Unexpected error. System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:4444
   at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress)
   at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception)
   --- End of inner exception stack trace ---
   at System.Net.HttpWebRequest.GetRequestStream(TransportContext& context)
   at System.Net.HttpWebRequest.GetRequestStream()
   at OpenQA.Selenium.Remote.HttpCommandExecutor.Execute(Command commandToExecute) in c:\Projects\WebDriver\trunk\dotnet\src\WebDriver\Remote\HttpCommandExecutor.cs:line 109
   at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters) in c:\Projects\WebDriver\trunk\dotnet\src\WebDriver\Remote\RemoteWebDriver.cs:line 836

我写的代码是：

            DesiredCapabilities capabilities = DesiredCapabilities.Firefox();
            capabilities.Platform = new Platform(PlatformType.Vista);
            capabilities.SetCapability("api_key", "REPLACE_API_KEY");
            capabilities.SetCapability("api_secret", "REPLACE_API_SECRET");  


            var remoteAddress = new Uri("http://122.176.112.91:4444/wd/hub");

           // ... but only if it supports javascript
            capabilities.IsJavaScriptEnabled = true;


            // Get a handle to the driver. This will throw an exception
            // if a matching driver cannot be located
            IWebDriver driver = new RemoteWebDriver(remoteAddress, capabilities);
            driver.Manage().Timeouts().ImplicitlyWait(new TimeSpan(0, 0, 30));


            // Query the driver to find out more information
            ICapabilities actualCapabilities = ((RemoteWebDriver)driver).Capabilities;

请帮我解决这个问题。

提前致谢。

堆栈跟踪表明本地计算机正在主动拒绝任何连接。仔细检查防火墙是否允许Firefox在所有端口上使用。

不幸的是，即使防火墙处于打开状态，我也遇到了这个问题： C# + VisualStudio + Multiple WebDriver instances = SocketExceptions

为什么我的代码无法连接到Selenium Remote Webdriver？
