newStream = objWebRequest.GetRequestStream()
newStream.Write(byteArray, 0, byteArray.Length)
newStream.Close()

'返回数据
Dim response As HttpWebResponse
Dim sr As StreamReader
Dim textResponse As String
response = objWebRequest.GetResponse()
sr = New StreamReader(response.GetResponseStream(), System.Text.Encoding.Default)
