使用 IXMLHTTPRequest 简单获取网页源代码

unit Unit1;
 
interface
uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;
type
  TForm1 = class(TForm)
    Memo1: TMemo;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  end;
var
  Form1: TForm1;
implementation
{$R *.dfm}
uses MsXML;
procedure TForm1.Button1Click(Sender: TObject);
var
  req: IXMLHTTPRequest;
begin
  req := CoXMLHTTP.Create; //较早的版本或许是 req := CoXMLHTTPRequest.Create;
  req.open('Get', 'http://del.cnblogs.com', False, EmptyParam, EmptyParam);
  req.send(EmptyParam);
  Memo1.Text := req.responseText;
end;
end.
