ussd - 交互式 USSD session 的 SMSLib 示例

Question

我有一个 USSD 应用程序，为用户提供交互式 session ，例如:

User> Dial USSD Shortcode
Serv> Return Main Menu
User> Select Option 1, e.g. "View Movie Times"
Serv> Return List of Cities
User> Select Option 3, e.g. Mumbai
Serv> Return List of Cinemas
User> etc ...

我想通过使用 SMSLib 来模拟用户来测试 USSD 服务器。

是否有示例 SMSLib 代码片段显示如何与 USSD 服务器执行交互式 USSD session ？

Answer 1

代码为link给出了使用smslib发送和接收USSD数据的示例:

// SendUSSD.java - Sample application.
//
// This application shows you the basic procedure for sending messages.
// You will find how to send synchronous and asynchronous messages.
//
// For asynchronous dispatch, the example application sets a callback
// notification, to see what's happened with messages.
