Why i can't load this page ?

[thefunkyjoint]

Hi,

When i try to load the page below on Chrome , it loads succesfully :

https://api.whatsapp.com/send?phone=551 ... &text=test

When i try to load the same page on CEF4Delphi, it only gives me a blank page. Actually, the content is loaded for a fraction of second, then the page goes blank.

Any hints ?

Thanks !

Error loading whatsapp://send?phone=551199996024&text=test
ERR_UNKNOWN_URL_SCHEME

dilfich is right. That web page is trying to open a resource in a URL with an unknown "whatsapp" scheme.

This known CEF3 issue might be related :

If you need to block those requests you can use the workaround described in the comments of that issue.

These are the code comments for the TChromium.OnProtocolExecution event :

Code: Select all

  ///
  // Called on the UI thread to handle requests for URLs with an unknown
  // protocol component. Set |allow_os_execution| to true (1) to attempt
  // execution via the registered OS protocol handler, if any. SECURITY WARNING:
  // YOU SHOULD USE THIS METHOD TO ENFORCE RESTRICTIONS BASED ON SCHEME, HOST OR
  // OTHER URL ANALYSIS BEFORE ALLOWING OS EXECUTION.
  ///

Official chrome also does not ship to this address, so this is not the problem of CEF3 itself..

hello friends, this way it works for me

Code: Select all

procedure TMiniBrowserFrm.Chromium1ProtocolExecution(Sender: TObject;
  const browser: ICefBrowser; const frame: ICefFrame;
  const request: ICefRequest; var allowOsExecution: Boolean);
begin
  //allowOsExecution:=true;
  //ShowMessage('test');
  Chromium1.StopLoad;
end;
