代碼如下:

Dim postData As String 
Dim byteArray As Byte() 
Dim objWebRequest As HttpWebRequest 
Dim newStream As Stream 

postData = "cell=短信供應(yīng)商提供信息1&enterpriseId=短信供應(yīng)商提供信息2&mobile=手機(jī)號(hào)1,手機(jī)號(hào)2&message=發(fā)送數(shù)據(jù)測(cè)試。。。" 
objWebRequest = WebRequest.Create("http://xxx.yyy.com.cn/SmsSend.jsp") 
objWebRequest.Method = "POST" 
objWebRequest.ContentType = "application/x-www-form-urlencoded" 

byteArray = System.Text.Encoding.UTF8.GetBytes(postData) 
objWebRequest.ContentLength = byteArray.Length 
newStream = objWebRequest.GetRequestStream() 
newStream.Write(byteArray, 0, byteArray.Length) 
newStream.Close() 

'返回?cái)?shù)據(jù) 
Dim response As HttpWebResponse 
Dim sr As StreamReader 
Dim textResponse As String 
response = objWebRequest.GetResponse() 
sr = New StreamReader(response.GetResponseStream(), System.Text.Encoding.Default) 
textResponse = sr.ReadToEnd()
