下面代码是delphi2010的，主要区别也就在于stringstream的 初使化，
Response := TStringStream.Create(”, TEncoding.UTF8); 改成
Response := TStringStream.Create(‘ ‘);
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, IdBaseComponent, IdComponent, IdTCPConnection, IdTCPClient, IdHTTP,
StdCtrls;
type
TForm1 = class(TForm)
mmo1: TMemo;
btn1: TButton;
IdHTTP1: TIdHTTP;
Label1: TLabel;

Label2: TLabel;
Edit2: TEdit;
procedure btn1Click(Sender: TObject);
private
