使用CefGlue创建无窗口浏览器

Question

我正在开发一个MVC Web应用程序，我需要在该应用程序中搜索网站。我试图使用CefGlue library。我需要使用网站的网址创建一个浏览器。但是，我得到的浏览器不包含任何框架，我没有收到任何错误：

CefRuntime.Load();

// Start the secondary CEF process.
var cefMainArgs = new CefMainArgs(new string[0]);
var cefApp = new PCefApp();

// This is where the code path divereges for child processes.
if (CefRuntime.ExecuteProcess(cefMainArgs, cefApp, IntPtr.Zero) != -1)
{
      Debug.WriteLine("CefRuntime could not the secondary process.");
}

// Settings for all of CEF (e.g. process management and control).
var cefSettings = new CefSettings
{
     SingleProcess = false,
     MultiThreadedMessageLoop = true
};

// Start the browser process (a child process).
CefRuntime.Initialize(cefMainArgs, cefSettings, cefApp, IntPtr.Zero);

// Instruct CEF to not render to a window at all.
CefWindowInfo cefWindowInfo = CefWindowInfo.Create();
cefWindowInfo.SetAsWindowless(IntPtr.Zero, false);

// Settings for the browser window itself (e.g. should JavaScript be enabled?).
var cefBrowserSettings = new CefBrowserSettings();

// Initialize some the cust interactions with the browser process.
// The browser window will be 1280 x 720 (pixels).
var cefClient = new DemoCefClient(1280, 720);


// Start up the browser instance.
string url = "https://www.website.com";
var browser = CefBrowserHost.CreateBrowserSync(cefWindowInfo, cefClient, cefBrowserSettings, url);
Debug.WriteLine(browser.GetFrameNames().Count());
Runtime.Shutdown();

我从this post

的代码开始

如果需要，我可以发布DemoCefRenderHandler，DemoCefLoadHandler，PCefApp代码。

browser.GetFrameNames（）。Count（）返回0

感谢任何帮助
