HttpWebRequest上的MediaType屬性的有效值是什麼？什麼是HttpWebRequest上的MediaType屬性的有效值
我想要做這樣的事情：
Dim url As String = HttpContext.Current.Request.Url.AbsoluteUri
Dim req As System.Net.HttpWebRequest = DirectCast(System.Net.WebRequest.Create(New Uri(url)), System.Net.HttpWebRequest)
' Add the current authentication cookie to the request
Dim cookie As HttpCookie = HttpContext.Current.Request.Cookies(FormsAuthentication.FormsCookieName)
Dim authenticationCookie As New System.Net.Cookie(FormsAuthentication.FormsCookieName, cookie.Value, cookie.Path, HttpContext.Current.Request.Url.Authority)
req.CookieContainer = New System.Net.CookieContainer()
req.CookieContainer.Add(authenticationCookie)
req.MediaType = "PRINT"
Dim res As System.Net.WebResponse = req.GetResponse()
'Read data
Dim ResponseStream As Stream = res.GetResponseStream()
'Write content into the MemoryStream
Dim resReader As New BinaryReader(ResponseStream)
Dim docStream As New MemoryStream(resReader.ReadBytes(CInt(res.ContentLength)))
感謝。
至少它分開到兩個問題，所以不會太本地化，而不是由他人使用。 –
我唯一的問題是「什麼是HttpWebRequest的MediaType屬性的有效值？」剩下的就是我如何使用它。對不起，如果不明確。 –
