I know this has been asked a number of different times before, but none of the solutions suggested there have worked. I'm trying to give cefsharp custom html in the most recent release of cefsharp/offscreen via nuget. Here's a sample of the code:
private void Start(string cachePath)//unsafe tp call twice currently
{
var settings = new CefSettings()
{
//By default CefSharp will use an in-memory cache, you need to specify a Cache Folder to persist data
CachePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "CefSharp\\Cache")
};
//Now for the internals
Cef.Initialize(settings, performDependencyCheck: false, browserProcessHandler: null);
Thread.Sleep(500);
browser = new ChromiumWebBrowser("dummy:");
Thread.Sleep(500);
}
private int CleanMemory()
{
Cef.Shutdown();
return 1;
}
private async void TakePictures()
{
//Reduce rendering speed to one frame per second so it's easier to take screen shots
//browserSettings.WindowlessFrameRate = 1;
while (m_ReceivedObjects.Any() && currentImageToBeProcessed.IsRendered == false)
{
currentImageToBeProcessed = m_ReceivedObjects.Dequeue();
//await LoadPageAsync(browser, currentImageToBeProcessed.filePath, currentImageToBeProcessed.rawHtml);
currentImageToBeProcessed.IsRendered = true;
string h = "< html >< head >< style > body { background - color: #93B874; } h1 { background - color: #00b33c; } p { background - color: #FFFFFF); } </ style >"
+ "</ head > < body >< h1 > Header with Green Background </ h1 >< p > Paragraph with white background </ p ></ body ></ html > ";
//CefSharp.WebBrowserExtensions.LoadHtml(browser, h, "http://www.example.com/");
//browser.LoadHtml("<html><body><h1>Hello world!</h1></body></html>", "http://example.com/");
//browser.Load("https://www.google.com/");
browser.Load("data:,Hello%2C%20World!");// LoadHtml("<html><body><h1>Hello world!</h1></body></html>", "http://example.com");
//browser.Load("data:text/html," + System.Web.HttpUtility.UrlPathEncode(currentImageToBeProcessed.rawHtml));
Thread.Sleep(2000);
await browser.ScreenshotAsync().ContinueWith(processHTML);
}
}
Near the bottom, with the commented lines are where the trouble is.
I've tried loadHtml, loadString, and load with a variety of different url and data uri types. None have worked.
The google page and all 'actual' url's do work though. (the 2 sec sleep is a placeholder till I have more time.)
