我有一个可以在 AWS 控制台中完美运行的机器人。
我试图让它在使用 AWS MobileHub 的移动应用程序中运行，但效果不佳，我不知道为什么我完全被卡住了。
描述：我提出一个项目名称的请求，以获取该项目的任务列表。但首先我必须连接。“连接”请求从我的后端获取一个令牌并将其放入sessionAttributes中。其他请求必须在sessionAttributes中包含此令牌，否则机器人将要求进行身份验证。
该工作流程适用于 AWS 控制台机器人：
- 请求“项目 123 的任务” -> 回答“您必须进行身份验证”
- 请求“连接” -> 回答“您现在已连接”
- 请求“项目 123 的任务” -> 回答“项目 123 的任务是 4、8、11。选择一个任务以获取详细信息。”
现在应用程序会发生什么，在文本模式下：
- 请求“项目 123 的任务” -> 回答“您必须进行身份验证”
- 请求“连接” -> 无应答
- 请求“项目 123的任务”-> 应用程序崩溃
在第 3 步登录 Android Studio（崩溃）：

在这里使用移动应用程序上的语音：
- 请求“项目 123 的任务” -> 回答“您必须进行身份验证”
- 请求“连接” -> 回答“您现在已连接”
- 请求“项目 123 的任务” -> 回答“您必须进行身份验证”
在第 1 步和第 3 步登录 Android Studio：

所以我尝试更改 lambda，所以我不需要连接部分（但它仍然使用请求的令牌，我只是在 lambda 中编写了令牌，而不是从后端获取它）。
- 在 AWS 控制台中，我得到了任务列表
- 在带有文本的移动设备上，我得到了任务列表
- 手机有语音不行

我不知道该怎么做，我什至不知道如何记录事情，如何检查从应用程序发送到 Lex 的内容以及 Lex 发回的内容。谢谢你的帮助。
