AngleSharp 自带的HttpRequest参数设置

AngleSharp自带一个获取网址源码的api，可以方便的从web取得html

var config = Configuration.Default.WithDefaultLoader();            
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);

如果目标站需要特定的头的话，就需要设置一些头参数了，示例代码如下

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");

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);

效果

当然，这只是针对一般的需求，如果有更高的需求，还是自己构建http请求，结果传给AngleSharp
