网上已经有类似的代码，但是效率很低,以下代码非常快速完成。本人在支付宝免签中使用以下方式。
代码语言：javascript复制 //获取浏览器的cookies
string Webcookies = webBrowser.Document.Cookie;
//通过HTTP请求加载测试
HttpHelper http = new HttpHelper();
HttpItem item = new HttpItem()
{
URL = this.contacturl,
Method = "get",
Encoding = Encoding.UTF8,
Cookie = Webcookies,
Accept= "application/json, text/javascript, */*; q=0.01",
ContentType = "text/plain",
UserAgent =
"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36",
};
item.Header.Add("Accept-Language", "zh-CN,zh;q=0.8");
item.Header.Add("X-Requested-With", "XMLHttpRequest");
item.Header.Add("Accept-Encoding", "gzip, deflate, sdch, br");
//得到HTML代码
HttpResult result = http.GetHtml(item);
string html = result.Html;HttpHelper类由苏飞大神提供。需要可直接联系我索取。
