这里以qq农场做举例，以下内容绝大部分转贴：
登录农场有两个渠道：
1、通过QQ校友登录；
2、通过QQ空间登录；
介绍一下工具：fiddler（HTTP抓包工具）
这个是在空间渠道登录的截图：
可以看到，从空间登录农场的地址是：http://happyfarm.qzone.qq.com/
从校友登录农场的地址：http://happyfarm.xiaoyou.qq.com/ 紧接着POST了一个包到：http://happyfarm.qzone.qq.com/api.php?mod=user&act=run
可以看见 body一栏内，POST的数据主要包括两大部分：
1、各功能swf的版本；
2、farmkey 和 farmtime；（这是一组对应的编码，farmkey是依据farmtime生成的一组32位的MD5码；
顺带介绍一下时间戳。也就是上面的farmtime；详细请参见 时间戳-百度百科
Delphi将当前时间转换成时间戳代码：DatetimeToUnix(Now - 8 / 24)；（中国处于GMT +8时区）
记得在uses里加上DateUtils
核心内容： 返回的数据内容，也就是HTML源码。

上面的这些是JSON数据格式！可以用firefox 带的json插件来分析。当然也有其他工具。后面会讲到。
分析：
可以看到，登录后会发一个（我们定义为run动作）数据，告诉服务器开始游戏，服务器立即返回当前登录帐户的农场信息，也就是以上的JSON格式的数据。
也就是说，只要能模拟发出首个POST数据包即可获得自己农场的信息。
网上有牛人破解了farmtime和farmkey的关系，我这里把规则写好了。
获取farmkey：
function TCommon.getFarmKey(time: TDateTime): string;
var
md5: TIdHashMessageDigest5;
temp1: Integer;
temp3: string;
begin
temp3 := 'sdoit78sdopig7w34057';
temp1 := DatetimeToUnix(time - 8 / 24);
Delete(temp3, 1, temp1 mod 10);
temp3 := IntToStr(temp1) + temp3;
md5 := TIdHashMessageDigest5.Create;
Result := LowerCase(md5.AsHex(md5.HashValue(temp3)));
end;
不过这个farmkey 还有以上的JSON数据 tx 每过一段是会变动的。发在这只是参考。更深入交流更多的讨论。欢迎加入 易语言快手双修群 95353051 共同进步！那里有更详细的图文教程。数量多。就不要一一贴出！上面只是给个引子
