我无法通过VB.NET中的amazon SNS向移动设备发送消息 [英] I can not send message to mobile via amazon SNS in VB.NET

问题描述

我想通过Amazon SNS将短信发送给用户.i在vb.net中编写了以下代码但发生错误消息属性'AWS.SNS.SMS.SMSType'具有无效的消息属性类型，集合支持的类型前缀是Binary，Number和String。.......我不知道按钮点击事件中code.my代码中的问题在哪里：



我的尝试：

进口亚马逊。 SimpleNotificationService 
 Imports Amazon.SimpleNotificationService.Model 
 Public Class Form1 
 Dim myclient As New AmazonSimpleNotificationServiceClient 
 Private Sub Button1_Click（sender As Object，e As EventArgs）Handles Button1.Click 
 Dim snsreq As New PublishRequest 
 Dim snsres As New PublishResponse 
 Dim snsmsgstng As New Dictionary（Of String，MessageAttributeValue）（）
 snsmsgstng.Add（AWS.SNS.SMS.SenderID，新的MessageAttributeValue（）使用{.StringValue =testing ，.DataType =string}）
 snsmsgstng.Add（AWS.SNS.SMS.SMSType，New MessageAttributeValue（）With {.StringValue =Promotional，。DataType =string}）
 snsreq.MessageAttributes = snsmsgstng 
 snsreq.PhoneNumber =+ 972543784512'电话号码
 snsreq.Message =你得到消息，如果是，那么告诉我??? ..
 snsres = myclient.Publish（snsreq）
 End Sub 
 End Class 

i还在app.config中添加以下内容

< appSettings> 
< add key =AWSAccessKeyvalue =MYAWSAccessKey/> 
< add key =AWSSecretKeyvalue =MYAWSSecretKey/> 
< add key =AWSRegionvalue =ap-southeast-1/> 
< / appSettings> 

请告诉我应该在哪里更改代码...... !!!

解决方案

尝试String（而不是string）

What I have tried:

 Imports Amazon.SimpleNotificationService
 Imports Amazon.SimpleNotificationService.Model
 Public Class Form1
     Dim myclient As New AmazonSimpleNotificationServiceClient
     Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim snsreq As New PublishRequest
        Dim snsres As New PublishResponse
        Dim snsmsgstng As New Dictionary(Of String, MessageAttributeValue)()
        snsmsgstng.Add("AWS.SNS.SMS.SenderID", New MessageAttributeValue() With {.StringValue = "testing", .DataType = "string"})
        snsmsgstng.Add("AWS.SNS.SMS.SMSType", New MessageAttributeValue() With {.StringValue = "Promotional", .DataType = "string"})
        snsreq.MessageAttributes = snsmsgstng
        snsreq.PhoneNumber = "[phone]"     'phone No
        snsreq.Message = "you get message ,if yes then tells me???.."
        snsres = myclient.Publish(snsreq)
     End Sub
End Class

<appSettings  >
 <add  key="AWSAccessKey" value="MYAWSAccessKey" />
