我想创建一个小实用程序，用户可以通过 txtlocal API 发送短信。用于 VB.net 的 txtlocal 提供代码片段。我只是创建一个简单的表单并复制粘贴代码，信用余额检查功能工作正常，但通过 Win Form 发送短信不起作用。这是代码片段 -
来自 txtlocal 的代码片段 -
Private Function SendSMS_txtLocal(ByVal Test As Boolean, _
ByVal From As String, _
ByVal Message As String, _
ByVal SendTo As String, _
ByVal URL As String) As String
' Send a message using the txtLocal transport
Const TransportURL As String ="http://www.txtlocal.com/sendsmspost.php"
Const TransportUserNameAs String ="me@myemail.com"
Const TransportPasswordAs String ="mypassword"
Const TransportVerboseAs Boolean =True
Dim strPost As String
' Build POST String
strPost = "uname=" + TransportUserName _
+ "&pword=" + TransportPassword _
+ "&message=" + System.Web.HttpUtility.UrlEncode(Message) _
+ "&from=" + From _
+ "&selectednums=" + SendTo
If URL "" Then
strPost += "&url=" + URL
End If
If Test = True Then
strPost += "&test=1"
End If
If TransportVerbose =True Then
strPost += "&info=1"
End If
' Create POST
Dim request As WebRequest = WebRequest.Create(TransportURL)
request.Method = "POST"
Dim byteArray As Byte() = Encoding.UTF8.GetBytes(strPost)
request.ContentType = "application/x-www-form-urlencoded"
request.ContentLength = byteArray.Length
Dim dataStream As Stream = request.GetRequestStream()
dataStream.Write(byteArray, 0, byteArray.Length)
dataStream.Close()
' Get the response.
Dim response As WebResponse = request.GetResponse()
dataStream = response.GetResponseStream()
Dim reader As New StreamReader(dataStream)
Dim responseFromServerAs String = reader.ReadToEnd()
' Clean upthe streams.
reader.Close()
dataStream.Close()
response.Close()
' Return result to calling function
If responseFromServer.Length > 0 Then
Return responseFromServer
Else
Return CType(response, HttpWebResponse).StatusDescription
End If
End Function
我这样调用函数 -
SendSMS_txtLocal(0, TextBox1.Text, TextBox2.Text, TextBox3.Text, "http://www.txtlocal.com/sendsmspost.php")
这是我的表单设计 -
请建议 - 代码有什么问题..
谢谢和最好的问候
