///

/// Post获取信息
///

/// 实体对象
/// post url
/// post data
///
public static T PostOfUrl(string url, string data)
{
System.Net.HttpWebRequest httpWebRequest = (HttpWebRequest)System.Net.WebRequest.Create(url);
httpWebRequest.Method = "POST";

httpWebRequest.Headers.Add("Accept-Charset", "utf-8");

byte[] postBytes = Encoding.UTF8.GetBytes(data);
//httpWebRequest.ContentType = "text/xml";
httpWebRequest.ContentType = "application/json; charset=utf-8";// httpWebRequest.ContentLength = Encoding.UTF8.GetByteCount(data);//strJson为json字符串
Stream stream = httpWebRequest.GetRequestStream();
stream.Write(postBytes, 0, postBytes.Length);
stream.Close();//发送完毕，接受返回值
var response = httpWebRequest.GetResponse();
Stream streamResponse = response.GetResponseStream();
StreamReader streamRead = new StreamReader(streamResponse);
String responseString = streamRead.ReadToEnd();
JavaScriptSerializer js = new JavaScriptSerializer();
var list = js.Deserialize(responseString);
return list;
}
