Delphi Qjson

使用QJSON解析数据：

 JSon 字符串：

{"Code":1,"Msg":"",
"Data":[{"NetType":"电信","ServerName":"test1","ServerAddr":"127.0.0.1:30001","ServerIp":"55551","ServerPort":3000,"OnlineCount":300,"MaxOnlineCount":0},{"NetType":"电信","ServerName":"test1","ServerAddr":"::13000","ServerIp":"::1","ServerPort":3000,"OnlineCount":3,"MaxOnlineCount":0},{"NetType":"电信","ServerName":"test1","ServerAddr":"127.0.0.1:3000","ServerIp":"::1","ServerPort":3000,"OnlineCount":3,"MaxOnlineCount":0}]}

Delphi代码：

procedure TForm2.Button1Click(Sender: TObject);
var
  Json,AItem:TQJson;
  i:Integer;

begin
    Json:=TQJson.Create;
    Json.Parse(Memo1.Text);
    //ShowMessage(Json.AsString);

    AItem := Json.ItemByName('Data') ;
    for I := 0 to AItem.Count-1 do
    begin
      Memo2.Lines.Add(AItem.Items[i].ValueByName('NetType',''));
      Memo2.Lines.Add(AItem.Items[i].ValueByName('ServerAddr',''));
      Memo2.Lines.Add(AItem.Items[i].ValueByName('ServerIp',''));
      Memo2.Lines.Add(AItem.Items[i].ValueByName('ServerPort',''));
      Memo2.Lines.Add(AItem.Items[i].ValueByName('OnlineCount',''));
      Memo2.Lines.Add(AItem.Items[i].ValueByName('MaxOnlineCount',''));
      Memo2.Lines.Add('-----------------------------------------')
    end;
end;
