Awesomium有没有类似与webBrowser.Navigate(..,post data，...)

Question

using Awesomium.Core;
using Awesomium.Windows.Forms;


request.AppendUploadBytes(bytes, (uint)bytes.Length);
request.Method = "POST";
request.AppendExtraHeader("Content-Type", "application/x-www-form-urlencoded"); //"multipart/form-data");

怎么用post方法将数据发送url上
