request = (HttpWebRequest)WebRequest.Create(url);
if (Const.session != null)
{
request.Headers.Add("Cookie", Const.session);
}
request.Timeout = 30000; //設定超時值
request.ContentType = "application/octet-stream";
request.Method = "POST";
request.ContentLength = outData.Length;
stream = request.GetRequestStream();
stream.Write(outData, 0, outData.Length);
stream.Flush();
stream.Close();
Const.uiWaitMessage = "請求發送完畢，開始接收數據";
Thread.Sleep(500);
//發送完畢
//接收數據
response = (HttpWebResponse)request.GetResponse();
if (Const.session == null)
{// 注銷后要清除Common.session
String cookie = response.GetResponseHeader("Set-Cookie");
if (cookie != null)
{
int n = cookie.IndexOf(';');
if (n > -1) Const.session = cookie.Substring(0, n);
}
}
使用
if (Const.session == null)
{// 注銷后要清除Common.session
String cookie = response.GetResponseHeader("Set-Cookie");
if (cookie != null)
{
int n = cookie.IndexOf(';');
if (n > -1) Const.session = cookie.Substring(0, n);
}
}
可以獲得并保存網站分配的Session信息
這樣每次訪問指定url的時候就可以先用
if (Const.session != null)
{
request.Headers.Add("Cookie", Const.session);
}
來添加Cookie，將已獲得Session信息發送到網站。
