控制台中动态创建Webbrowser后获取源码

Delphi(Pascal) code

program Project1;{$APPTYPE CONSOLE}uses  SysUtils,SHDocVw,MSHTML;var  iall : IHTMLElement;  Webbrowser:TWebBrowser;begin  WebBrowser :=TWebBrowser.Create(nil);  WebBrowser.Navigate('http://192.168.1.101/1.html');  Sleep(1000);  if Assigned(WebBrowser.Document) then  begin    iall := (WebBrowser.Document AS IHTMLDocument2).body;    while iall.parentElement <> nil do    begin      iall := iall.parentElement;    end;    Writeln(iall.outerHTML);  end;  Readln;  Webbrowser.Free;end.

1.html里存放的是文本 "success=true"

使用上边的代码无法正确输出success=true这一串字符

而在VCL Forms Application 中则可以,请问是哪的原因?

如何解决呢?

If all you want is return result of some URL why do you need to embed whole webbrowser? if you just need the result then try Indy.

retStr := IdHTTP.Get('http://192.168.1.101/1.html');

Hope it helps.

IdHTTP.Get will also return you whole HTML or 源码 of that link.

Do you want to display the results as HTML Browser??

Now your requirements are clear. Use below code to retrieve HTML via webbrowser.

Delphi(Pascal) code

procedure Pause(const ADelay: Cardinal);var   Start: Cardinal;begin    Start := Windows.GetTickCount;    repeat          Application.ProcessMessages;    until Int64(Windows.GetTickCount) - Int64(Start) >= ADelay;end;function getHTML(WB : TWebBrowser) : String ; var   PersistStream: IPersistStreamInit;   Stream: IStream;   strStream: TStringStream; begin   Result := '';   if Assigned(WB.Document) then   begin   PersistStream := WB.Document as IPersistStreamInit;   strStream := TStringStream.Create('') ;   try     Stream := TStreamAdapter.Create(strStream, soReference) as IStream;     if Succeeded(PersistStream.Save(Stream, True)) then         Result := strStream.DataString;   finally     strStream.Free;   end;   end;end;procedure TForm1.Button1Click(Sender: TObject);var   browser : TWebBrowser;   Flags : OleVariant;begin     Flags := navNoHistory or navNoReadFromCache or navNoWriteToCache;     browser := TWebBrowser.Create(nil);     try       browser.Navigate(Edit1.Text,  Flags);       while browser.Busy do         Pause(5);       memo1.Text := getHTML(browser);     finally           browser.Free;     end;end;

Definitely you can not have any TWinControl descendent in console environment. And plus I don't understand why would you go with WinControl in non-window (console) environment?
