Recaptcha检测PhantomJS

Question

当我通过Selenium使用PhantomJS获得recaptcha V2挑战（选择答案和图片）时，挑战比经典浏览器（例如Chrome或Firefox）更难......

Recaptcha如何到达检测PhantomJS？

我的代码：

        PhantomJSOptions options = new PhantomJSOptions();
        options.AddAdditionalCapability("phantomjs.page.settings.userAgent", "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36");
        options.AddAdditionalCapability(CapabilityType.AcceptSslCertificates, true);
        options.AddAdditionalCapability("requireWindowFocus", true);
        options.AddAdditionalCapability("enablePersistentHover", false);

        PhantomJSDriver driver = new PhantomJSDriver(options);
        driver.Navigate().GoToUrl("http://deathbycaptcha.com/");
        Console.WriteLine("Page ouverte");
        driver.Manage().Window.Maximize();

        driver.SwitchTo().Frame(driver.FindElement(By.Name("undefined")));
        driver.FindElement(By.CssSelector("div[class=recaptcha-checkbox-checkmark]")).Click();
        Thread.Sleep(1500);
        lock(lockThis){
            driver.GetScreenshot().SaveAsFile("screeno.jpg", ImageFormat.Jpeg);
        }
        Console.WriteLine("Screen realise")

一些想法？

尝试安装fiddler并比较程序中发送的标头与标准浏览器http://www.telerik.com/fiddler。

使用PhantomJS时需要更改用户代理。
