步骤 3：创建目的 (AWS CLI)

为 OrderFlowersBot 自动程序创建一个目的并提供三个槽 (参数)。这些槽允许自动程序完成以下目的：

• FlowerType 是一个自定义槽类型，用于指定可以订购哪些类型的鲜花。

• AMAZON.DATE 和 AMAZON.TIME 是内置槽类型，用于获取从用户那里送花的日期和时间。

要运行本练习中的命令，您需要知道将在其中运行命令的区域。有关区域列表，请参阅 模型构建配额 。

创建 OrderFlowers目的 (AWS CLI)

1. 创建名为 OrderFlowers.json 的文本文件。将 JSON 代码从 OrderFlowers.json 复制到该文本文件中。

2. 在 AWS CLI 中，调用 PutIntent 操作以创建目的。此示例的格式适用于 Unix、Linux 和 macOS。对于 Windows，请将每行末尾的反斜杠 (\) Unix 行继续符替换为脱字号 (^)。

   aws lex-models put-intent \
      --region region \
      --name OrderFlowers \
      --cli-input-json file://OrderFlowers.json

   服务器响应如下：
