HttpWebRequest的详细方法二：
System.Net.HttpWebRequest myRequest = null;
System.Net.HttpWebResponse myResponse = null;
Stream reqStream = null;
Stream resStream = null;
string signkey = "", url = "";
string sdateStr = DateTime.Now.AddDays(-6).ToString("yyyyMMdd") + "000001";
try
{
signkey = XH_ChannelKey;//key
url = XH_ChannelUrl; //接口地址
url += "fromDate=" + sdateStr;
url += "&version=1.4";//版本号
url += "&hmac=" + MD5Encrypt(signkey + sdateStr + "1.4");
//想服务器端发送请求，获取订单信息
myRequest = System.Net.WebRequest.Create(url) as System.Net.HttpWebRequest;
//--------------------- c#中HttpWebRequest使用Proxy实现指定IP的域名请求 ---------------------------------
//需要使用Proxy和其配置 (代理ip)
////System.Net.WebProxy proxy = new System.Net.WebProxy("115.238.128.138", 80);
////myRequest.Proxy = proxy;
//------------------------------------------------------
myRequest.Timeout = 1000 * 60 * 1;//1分钟超时 1 minutes timeout
myRequest.Method = "POST";
myResponse = myRequest.GetResponse() as System.Net.HttpWebResponse;
Stream myResponseStream = myResponse.GetResponseStream();
StreamReader myStreamReader;
myStreamReader = new StreamReader(myResponseStream, System.Text.Encoding.GetEncoding("utf-8"));
//post返回的数据
string receiveData = myStreamReader.ReadToEnd();
myStreamReader.Close();
myResponseStream.Close();
}
catch (Exception ex)
{
string stacktrace = ex.StackTrace;//获得详细的错误位置
string errpoint = stacktrace.Substring(stacktrace.IndexOf("位置"), stacktrace.Length - stacktrace.IndexOf("位置"));
Common.WriteTextLog("Error","", ex.Message + Environment.NewLine + errpoint);
}
finally
{
if (resStream != null)
{
resStream.Close();
}
if (reqStream != null)
{
reqStream.Close();
}
if (myResponse != null)
{
myResponse.Close();
}
if (myRequest != null)
{
myRequest.Abort();
}
////特别留意这句Sleep的调用！！
System.Threading.Thread.Sleep(16);
}
