如何在VB.net HTTP函數中傳遞值？

Question

我想創建一個小的實用程序，用戶可以在其中通過txtlocal API發送SMS。 VB.net的txtlocal優惠代碼段。 我只創建了一個簡單的表單並復制粘貼了代碼，“貸方余額”檢查功能可以正常工作，但無法通過Win Form發送SMS。 這是代碼段-

txtlocal的代碼段-

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

我這樣調用函數-

SendSMS_txtLocal(0, TextBox1.Text, TextBox2.Text, TextBox3.Text, "http://www.txtlocal.com/sendsmspost.php")

這是我的表格設計-

請提出建議-代碼有什么問題。

謝謝與最好的問候

從外觀上看，您調用的函數是錯誤的。 嘗試：

SendSMS_txtLocal(0, TextBox1.Text, TextBox2.Text, TextBox3.Text, "??")

您添加的URL未被用作URL，而是被發送到要發送給它們的信息字符串中的txtlocal ，不知道其用途或目的，請在其網站上閱讀？
