vb.net http post的两种方法

概述剛剛看到一段簡短的程式是使用vb.net 開發應用程式來對網站使用POST的方式傳送資料 Dim web As New System.Net.WebClient() web.Headers.Add("Content-Type", "application/x-www-form-urlencoded") Dim d As Byte() = System.Text.Encoding.ASCII.Get

剛剛看到一段簡短的程式是使用vb.net 開發應用程式來對網站使用POST的方式傳送資料

Dim web As New System.Net.WebClIEnt()
web.headers.Add("Content-Type","application/x-www-form-urlencoded")
Dim d As Byte() = System.Text.EnCoding.ASCII.GetBytes("SEARCHSTRING=test")
Dim res As Byte() = web.UploadData("http://www.baIDu.com","POST",d)
msgBox(System.Text.EnCoding.ASCII.GetString(res))

比起下面這種方法是簡單許多!

Dim httpResp As System.Net.httpWebResponse Dim httpUrl2 As New System.Uri("http://www.baIDu.com") Dim req As httpWebRequest req = CType(WebRequest.Create(httpUrl2),httpWebRequest) req.Method = "POST" req.ContentType = "application/x-www-form-urlencoded" Dim bytesData() As Byte = EnCoding.ASCII.GetBytes("SEARCHSTRING=test") req.ContentLength = bytesData.Length Dim poststream As Stream = req.GetRequestStream() poststream.Write(bytesData,bytesData.Length) poststream.Close() Dim res As httpWebResponse = CType(req.GetResponse(),httpWebResponse) Dim reader As StreamReader = New StreamReader(res.GetResponseStream,System.Text.EnCoding.GetEnCoding("BIG5")) Dim respHTML As String = reader.ReadToEnd() res.Close() MsgBox(respHTML)
