我最近使用 vb.net 连接到 SMS 提供程序 API
我创建了一个组表并在该组中插入了所有数字，然后到达每一行并发送触发 API 以处理发送。短信不是发给所有群成员的，它只成功发送到群中的第一个手机号码。
如何解决这个问题呢 ？我想我必须在每次发送之间设置一个延迟，但我没有用。我的代码如下：
Function GetGroupsMobileNumbers() As ArrayList
Dim MobileNumbersArrayList As New ArrayList
For Each Contact As FilsPayComponent.ContactAddress In FilsPayComponent.ContactAddress.GetAllContactAddressByGroupId(ddlGroup.SelectedValue)
MobileNumbersArrayList.Add(Contact.Mobile)
Next
Return MobileNumbersArrayList
End Function
Protected Sub btnSend_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSend.Click
If ddlGroup.SelectedValue = 0 Then
lbResult.Text = "No groups selected"
Exit Sub
End If
Dim MobileNumbersArrayList As ArrayList
MobileNumbersArrayList = GetGroupsMobileNumbers()
If MobileNumbersArrayList.Count = 0 Then
lbResult.Text = "Group doesnt contain numbers"
Exit Sub
End If
Dim TotalNo As Integer = FilsPayComponent.ContactAddress.AddressContactsCount(ddlGroup.SelectedValue)
If MobileNumbersArrayList.Count * messagecount.Value <= FilsPayComponent.SmSUser.GetSmSUserByUserId(Context.User.Identity.Name).Balance Then
Dim txtMsg As String
Dim smstype As Integer
If hidUnicode.Value <> "1" Then
txtMsg = txtMessage.Text
smstype = 1
Else
txtMsg = ConvertTextToUnicode(txtMessage.Text)
smstype = 2
End If
Dim x As Integer
'For Each Contact As FilsPayComponent.ContactAddress In FilsPayComponent.ContactAddress.GetAllContactAddressByGroupId(ddlGroup.SelectedValue)
For Each Contact In MobileNumbersArrayList.ToArray
Dim toMobile As String = Contact.Mobile
If toMobile.Length > 10 Then
Dim ExecArrayList As ArrayList
ExecArrayList = SendSMS(toMobile, txtMsg, smstype)
'-- give the excution more time
If ExecArrayList.Count < 1 Then
Threading.Thread.Sleep(1000)
End If
'-- give the excution more time
If ExecArrayList.Count < 1 Then
Threading.Thread.Sleep(1000)
End If
'-- give the excution more time
If ExecArrayList.Count < 1 Then
Threading.Thread.Sleep(1000)
End If
x = x + 1
' lbresult.Text = "Sent Successfully"
End If
Next
FilsPayComponent.SmSUser.RemoveSmsCredit(Context.User.Identity.Name, messagecount.Value * x)
Dim NewsmsarchiveItem As New FilsPayComponent.smsarchive
NewsmsarchiveItem.FromMobile = txtSenderID.Text
NewsmsarchiveItem.ToMobile = "0"
NewsmsarchiveItem.GroupId = ddlGroup.SelectedValue
NewsmsarchiveItem.DateSent = DateTime.Now
NewsmsarchiveItem.Msg = txtMessage.Text
NewsmsarchiveItem.GroupCount = x
NewsmsarchiveItem.Optional1 = Context.User.Identity.Name
NewsmsarchiveItem.Optional2 = "1"
NewsmsarchiveItem.MessageNo = messagecount.Value
Try
NewsmsarchiveItem.Addsmsarchive()
lbResult.Text = "Message sent successfully"
btnSend.Visible = False
Catch ex As Exception
lbResult.Text = ex.Message
End Try
Else
lbResult.Text = "Not enough credit, please refill "
End If
End Sub
Sub SendSMS(ByVal toMobile As String, ByVal txtMsg As String, ByVal smstype As Integer)
Dim hwReq As HttpWebRequest
Dim hwRes As HttpWebResponse
Dim smsUser As String = "xxxxxx"
Dim smsPassword As String = "xxxxxx"
Dim smsSender As String = "xxxxxx"
Dim strPostData As String = String.Format("username={0}&password={1}&destination={2}&message={3}&type={4}&dlr=1&source={5}", Server.UrlEncode(smsUser), Server.UrlEncode(smsPassword), Server.UrlEncode(toMobile), Server.UrlEncode(txtMsg), Server.UrlEncode(smstype), Server.UrlEncode(smsSender))
Dim strResult As String = ""
Try
hwReq = DirectCast(WebRequest.Create("http://xxxxx:8080/bulksms/bulksms?"), HttpWebRequest)
hwReq.Method = "POST"
hwReq.ContentType = "application/x-www-form-urlencoded"
hwReq.ContentLength = strPostData.Length
Dim arrByteData As Byte() = ASCIIEncoding.ASCII.GetBytes(strPostData)
hwReq.GetRequestStream().Write(arrByteData, 0, arrByteData.Length)
hwRes = DirectCast(hwReq.GetResponse(), HttpWebResponse)
If hwRes.StatusCode = HttpStatusCode.OK Then
Dim srdrResponse As New StreamReader(hwRes.GetResponseStream(), Encoding.UTF8)
Dim strResponse As String = srdrResponse.ReadToEnd().Trim()
Select Case strResponse
Case "01"
strResult = "success"
Exit Select
Case Else
strResult = "Error: " + strResponse
Exit Select
End Select
End If
Catch wex As WebException
strResult = "Error, " + wex.Message
Catch ex As Exception
strResult = "Error, " + ex.Message
Finally
hwReq = Nothing
hwRes = Nothing
End Try
End Sub
