delphi 谁帮我翻译下这段代码——高分
//是多线i多垃圾管理系统源码个基于多线程的模拟浏览器的 Get 和Post 方法的类,具体我也不大清楚,,
//也只能大概说说了.
unit web;
interface
uses
Classes,IdHTTP,SysUtils,IdCookieManager,IdMultipartFormData
,windows;
//类的声明
type
TWeb = class(TThread)
private
protected
procedure Execute; override; //重写父类TThread的Exeecute方法.
public
mode: Integer; //标志位:根据这个判断是Get还是Post
url: string; //Url地址
idhttp: TIDHttp; //Indy 的http组件
sl: TStringList;
mpfDS: TIdMultiPartFormDataStream; //用这个控件实现 Stream的提交方法的.
flag: Boolean; //标志位,代码没有读懂,不知道是控制什么状态的
err,html: string;
stm: TMemoryStream;
constructor create; //构建函数
end;
implementation
//构造函数 ,全是初始化声明的类,没啥好说的.
constructor TWeb.create;
begin

idhttp.CookieManager := TIDCookieManager.Create(idhttp);

inherited Create(True);
end;
//重写父类TThread的Exeecute方法.
procedure TWeb.Execute;
begin
while not Terminated do

if Suspended then continue; //不懂,估计是多线程的同步处理?
flag := True;
err := '';
html := '';
//根据mode判断执行的功能 1 :Get文本 2:Get 流 3 提交数组ts是上面定义的一个数组 4 提交Stream,估计是提交类似,文件一类的东西
Case mode of //1:get text 2:get stream 3:post ts 4:post mpfDS

//也是用Indy的idhttp实现提交功能, 没时间详细些了,lz可以查看INDY组件IDHTTP的控件的详细使用方法.
//可以hi我再进行交流...
