向Piwik提交Delphi POST请求期间的问题

我尝试向Piwik提交Delphi POST请求，如下所述：

我的Delphi实现如下所示：

  FPiwikRequest := '';
  FPiwikRequest := FPiwikRequest + Format('?cvar=PAGE_%s&', ['something']);
  FPiwikRequest := FPiwikRequest + Format('action_name=6new_%s&', ['ActionPage']);
  FPiwikRequest := FPiwikRequest + Format('idsite=%d&', [3]);
  FPiwikRequest := FPiwikRequest + Format('rec=%d&', [1]);
  FPiwikRequest := FPiwikRequest + Format('url=%s&', ['http://localhost/analytics/index45.html']);
  FPiwikRequest := FPiwikRequest + Format('urlref=%s&', ['http://localhost/analytics/index13.html']);
  FPiwikRequest := FPiwikRequest + Format('_id=%s&', ['231e3849e534a3c6']);
  FPiwikRequest := FPiwikRequest + Format('rand=%d', [Random(1000)]);
  json := SO;
  json.O['requests'] := SA([]);
  json.A['requests'].S[0] := FPiwikRequest;
  json.A['requests'].S[1] := FPiwikRequest_2;
  json.S['token_auth'] := 'ffff9fb80b9558e4529fe96902dffff';
  FPiwikRequest := json.AsString;
  HTTPClient.POST(PIWIK_HOME + FPiwikRequest, response); //HTTPClient => idHTTP class

提交请求后，Piwik脚本只处理提交的批量请求中的最后一个请求json.A['requests'].S[1]

*当我从Python提交相同的批量请求时，Piwik将处理来自提交的批量请求的两个请求

你对这种行为有什么想法吗

对不起，这篇文章。答案很简单：）其中一种方法如下所示

所以，您应该向方法POST添加参数

LRequestParams := TStringStream.Create();
try
  LRequestParams.WriteString(FPiwikRequest);  
  HTTPClient.POST(PIWIK_HOME, LRequestParams, response);
finally
  LRequestParams.Free;   
end;

HTTPClient是什么类？
