Amazon web services Amazon Lex与AWS Lambda的集成

我使用Alexa Skills Kit已经有一段时间了，我的代码部署在用Node Js编写的AWS Lambda中。现在我想通过AmazonLex服务将聊天机器人集成到其中。因此，我能够使用Amazon Alexa和Amazon lex控制我的设备。我的问题是，如果我在AmazonLex中使用与我在Alexa技能中相同的意图和插槽名称，AWS Lambda代码是否会开箱即用？或者我必须修改AWS Lambda代码以适应AWS Lex？

您必须适应Lex和Alexa之间的差异。最显著的区别是请求和响应格式

应注意的显著差异：

sessionattribtue

和

slot

的格式和传递之间的主要差异

Lex有4个内置的

slotTypes

，Alexa还没有使用：

AMAZON.EmailAddress、

、

AMAZON.Percentage

、

AMAZON.PhoneNumber

、

AMAZON.SpeedUnit

和

AMAZON.WeightUnit

。（）

Lex总是通过

inputTranscript

传递完整的用户输入。Alexa没有

Alexa为插槽值提供

分辨率

，但使用从输入中提取的原始数据填充实际插槽值

如果为该

slotType

设置了同义词，则Lex将自动解析插槽值

在和他们一起工作了很多次，并且经常处理这个问题之后，我更喜欢莱克斯而不是亚历克斯。我发现Lex更简单，提供了更多的开发人员自由和控制，即使您必须遵守Lex的每个输出通道的限制

比较请求/响应格式：
