http - 如何更快地分析HTTP Post响应

我写了一个简单的程序，定期检查数据。问题是检查过程随着时间的推移而变慢。首先，它在一秒钟内发送两个帖子，大约45秒后，它发送一个帖子，最终它完全停止。我不知道这里怎么了。

procedure TForm2.CheckURLs;
var
  lHTTP: TIdHTTP;
  IdSSL : TIdSSLIOHandlerSocketOpenSSL;
  N: Integer;
  Access: string;
  Params, Reply: TStringList;
  Cookie: TIdCookie;
begin
  lHTTP := TIdHTTP.Create(nil);
  try
    IdSSL := TIdSSLIOHandlerSocketOpenSSL.Create(lHTTP);
    IdSSL.SSLOptions.Method := sslvTLSv1;
    IdSSL.SSLOptions.Mode := sslmClient;
    lHTTP.IOHandler := IdSSL;
    lHTTP.ReadTimeout := 30000;
    lHTTP.HandleRedirects := True;
    lHTTP.Request.UserAgent := 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.76 Mobile Safari/537.36';
    lHTTP.Get('https://www.mywebserver.com', TStream(nil));
    Cookie := lHTTP.CookieManager.CookieCollection.Cookie['id', 'www.mywebserver.com'];
    if Cookie <> nil then
      Access := Cookie.Value;
  finally
  end;

  Params := TStringList.Create;
  Reply  := TStringList.Create;

  TTask.Create(
    procedure
    var
      N, m, i : integer;
    begin
      Params.Add('IDs=' +B.Strings[i]);
      try
        lHTTP.Request.CustomHeaders.Values['id'] := Access;
        lHTTP.Request.CustomHeaders.Values['X-Requested-With'] := 'XMLHttpRequest';
        lHTTP.Request.Referer := 'https://www.mywebserver.com/';
        lHTTP.Request.ContentType := 'application/x-www-form-urlencoded';
        lHTTP.Request.UserAgent := 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.76 Mobile Safari/537.36';
        lHTTP.ConnectTimeout := 0;
        Reply.Text := lHTTP.Post('https://www.mywebserver.com/', Params);

        if AnsiContainsStr(Reply.Text, 'nothing') then
        begin
          TThread.Synchronize(nil,
            procedure
            begin
              Memo1.Lines.Add(B.Strings[i]);
              Label2.Caption := Memo1.Lines.Count.ToString;
            end
          );
        end;
      finally
        Reply.Clear;
      end;
    end
  ).Start;
end;

最佳答案

除了Technicolor所说的，Delphi 10.1 Berlin中的TTask还存在时间问题，例如：
RSP-15233: TTask Stuck and take a very very long time to start
RSP-12557: TTask serialize parallel tasks without apparent reason
要避免这些问题，请尝试使用TThread.CreateAnonymousThread()而不是TTask。
