public string PostParameter(string url)
{ string message="";
GetOrderInfoMation order=new GetOrderInfoMation();
string Parameter = "orderno=" + order.GetOrderNos() + "&receiptdata=test&result=\"status\"=\"0\"; \r\n\"product_id\"=\"2\"; \r\n\"transaction_id\"=\"3\"; \r\n\"bid\"=\"4\"";
byte[] bytes = Encoding.UTF8.GetBytes(Parameter);
GetConfig con = new GetConfig();
string prfix = con.UrlPreFix;//获取地址前缀
string strURL = prfix + url;//创建一个访问地址
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(strURL);
request.Method = "POST";
request.ContentLength = bytes.Length;
request.ContentType = "text/xml";
using (Stream requestStream = request.GetRequestStream())
{
requestStream.Write(bytes, 0, bytes.Length);
}
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader sr = new StreamReader(response.GetResponseStream());
string jsonstr = sr.ReadToEnd();
return jsonstr;
if (response.StatusCode != HttpStatusCode.OK)
{
return "POST failed. Received HTTP+" + response.StatusCode + "";

}

}

在url页面处理请求 //接收receipt-data
byte[] byts = new byte[Request.InputStream.Length];
Request.InputStream.Read(byts, 0, byts.Length);
sReceiptData = System.Text.Encoding.Default.GetString(byts);
string[] Data = sReceiptData.Split('&');//获取参数

get请求

public string Response(string url)
{
try
{

GetConfig con = new GetConfig();

string prfix = con.UrlPreFix;//获取地址前缀
string strURL = prfix + url;//创建一个访问地址
System.Net.HttpWebRequest request;
request = (System.Net.HttpWebRequest)WebRequest.Create(strURL);//创建一个HTTP请求
request.Method = "get";//发送请求
System.Net.HttpWebResponse response;
response = (System.Net.HttpWebResponse)request.GetResponse();//获取响应
StreamReader sr = new StreamReader(response.GetResponseStream());
string jsonstr = sr.ReadToEnd();
return jsonstr;
}
catch (Exception)
{

return "The server connection error.";
}

}
