如何在 PhantomDriver(无头浏览器)中隐藏 FirefoxDriver(使用 Selenium)而不出现 findElement 函数错误? [英] How to hide FirefoxDriver (using Selenium) without findElement function error in PhantomDriver(headless browser)?
问题描述
我尝试制作隐藏的 FirefoxDriver.根据我的研究，我必须使用 PhantomJSDriver 但是当我使用 PhantomJSDriver driver.FindElement 语句不再起作用.
I try to make hidden FirefoxDriver. According to my research I must use PhantomJSDriver but when I use PhantomJSDriver driver.FindElement statement no longer does not work.
var options = new PhantomJSOptions();
options.AddAdditionalCapability("phantomjs.page.settings.userAgent",
"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko)
Chrome/40.0.2214.94 Safari/537.36");
PhantomJSOptions p = new PhantomJSOptions();
var service = PhantomJSDriverService.CreateDefaultService();
service.SslProtocol = "any";
service.ProxyType = "http";
service.WebSecurity = false;
service.IgnoreSslErrors = true;
var driver = new PhantomJSDriver(service, options);
driver.Navigate().GoToUrl("https://www.google.com.tr/");
Thread.Sleep(5000);
driver.FindElement(By.XPath("//*[@id='lst-ib']")).SendKeys("edd");
string s = driver.Url;
Console.WriteLine(s);
错误信息:
WebDriver.dll 中出现OpenQA.Selenium.NoSuchElementException"类型的未处理异常

还有其他隐藏 FirefoxDriver 的方法吗?你能帮帮我吗?
Is there any another way for hiding FirefoxDriver? Could you help me please?
推荐答案
我解决了.首先我们可以在不显示控制台的情况下使用 PhantomJS:
I solved it. First of all We can use PhantomJS without showing its console by this code:
IWebDriver driver;
var driverService = PhantomJSDriverService.CreateDefaultService();
driverService.HideCommandPromptWindow = true;
driver = new PhantomJSDriver(driverService);
第二个是我提到的错误.Google 会为浏览器返回不同的 HTML 页面，因此 PhantomJS 浏览器中的 Id 或 Xpath 将与我在打开 Firefox 时导出的不同.当我使用
Second for the error that I mentioned. Google return different HTML pages for browsers so the Id or Xpath in PhantomJS browser will be different from that I export it when I was opening Firefox. When I used
string html=driver.PageSource;
要知道正确的 XPath 或 Id，findElement 函数运行良好.
to know what the correct XPath or Id, findElement functiom is working well.
例如:对于 Google 网站结果FirefoxDriver 中第一个链接的 XPath 是
For example: For the Google site results The first link's XPath in FirefoxDriver is
"//*[@id='rso']/div/div/div[1]/div/div/h3/a"
PhantomJSDriver 中第一个链接的 XPath 是
The first link's XPath in PhantomJSDriver is
"//*[@id='ires']//ol/div[1]/h3/a"
