var config = Configuration.Default.WithDefaultLoader().With(requester);            
var document = await BrowsingContext.New(config).OpenAsync("https://www.cnblogs.com");
var cellSelector = "#editor_pick_lnk";
var top = document.QuerySelectorAll(cellSelector).FirstOrDefault().TextContent;
Console.WriteLine(top);

var requester = new DefaultHttpRequester("Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36");
requester.Headers.Add("accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8");
requester.Headers.Add("Test","test8888888888");
