如何在alexa技能发布会上从用户那里获得信息

Question

我有一个Alexa应用程序，它在首次启动时会在dynamoDB中查找用户id。如果没有，我希望它能向用户询问他们的ip地址。

我有一个可以收集IP的意图，但我想知道我是否可以从发布请求中触发该意图？

private SkillResponse LaunchRequestHandler(SkillRequest input, ILambdaContext context)
{
// Initialise response
var skillResponse = new SkillResponse
{
Version = "1.0",
Response = new ResponseBody()
};
// Output speech
SsmlOutputSpeech ssmlResponse = new SsmlOutputSpeech();
try
{
try
{
var strUserId = input.Session.User.UserId;
var request = new GetItemRequest
{
TableName = tableName,
Key = new Dictionary<string, AttributeValue>() { { "strUserId", new AttributeValue { S = strUserId } } },
};
var response = client.GetItemAsync(request);
// Check the response.
var result = response.Result;
var attributeMap = result.Item;
if (result.Item.Count() < 1)
{
ssmlResponse.Ssml = "<speak></speak>";
// Trigger intent to get IP address and port number.
}
else
{
ssmlResponse.Ssml = "<speak>Hi there. I'm not Cortana.</speak>";
// Give command guidance prompt.
}

}
catch (AmazonDynamoDBException e) { ssmlResponse.Ssml = "<speak>" + e.InnerException.Message + "</speak>"; }
catch (AmazonServiceException e) { ssmlResponse.Ssml = "<speak>" + e.Message + "</speak>"; }
catch (Exception e) { ssmlResponse.Ssml = "<speak>" + e.Message + "</speak>"; }
skillResponse.Response.OutputSpeech = ssmlResponse;
skillResponse.Response.ShouldEndSession = true;
}
catch
{
//ssmlResponse.Ssml = "<speak><audio src='/samples/ImSorryDave'/></speak>";
ssmlResponse.Ssml = "<speak>I'm sorry Dave. I'm afraid I can't do that.</speak>";
skillResponse.Response.OutputSpeech = ssmlResponse;
}
skillResponse.Response.ShouldEndSession = true;
return skillResponse;
}

我能想到的两个选项：

1. 你试过只询问IP地址吗？<speak> Hi there. What is your IP address?</speak>如果你确保你的IP地址意图有你可能期望用户如何回答这个问题的例子，那么这个意图应该被触发并发送给你的技能来处理。

2. 还可以了解Alexa如何通过意向链接为您处理一些对话框管理。那里的示例听起来与您的用例非常相似。
