使用 API 管理意图

意图决定系统可理解哪些用户请求以及要采取怎样的操作。在大多数情况下,您将使用 Dialogflow ES 控制台来管理意图。在高级场景中,您可能希望使用 API 来管理意图。本页介绍如何使用 API 创建、列出和删除意图。

准备工作

在阅读本指南之前,请先完成以下事项:

  1. 阅读 Dialogflow 基础知识
  2. 执行设置步骤

创建代理

如果尚未创建代理,请立即创建一个:

  1. 前往 Dialogflow ES 控制台
  2. 如果系统要求登录 Dialogflow 控制台,请登录。如需了解详情,请参阅 Dialogflow 控制台概览
  3. 点击左侧边栏菜单中的创建代理 (Create Agent)。如果您已有其他代理,请点击代理名称,滚动到底部,然后点击创建新代理 (Create new agent)。
  4. 输入您的代理名称、默认语言和默认时区。
  5. 如果您已经创建了项目,请输入该项目。如果要允许 Dialogflow 控制台创建项目,请选择创建新 Google 项目 (Create a new Google project)。
  6. 点击创建 (Create) 按钮。

将示例文件导入代理

本指南中的步骤对您的代理进行了假设,因此您需要导入为本指南准备的代理。 导入时,这些步骤使用“恢复”(restore) 选项,该选项会覆盖所有代理设置、意图和实体。

如需导入文件,请按以下步骤操作:

  1. 下载 room-booking-agent.zip 文件。
  2. 前往 Dialogflow ES 控制台
  3. 选择您的代理。
  4. 点击代理名称旁边的设置 按钮。
  5. 选择导出和导入 (Export and Import) 标签页。
  6. 选择从 ZIP 文件恢复 (Restore from ZIP),然后按照说明恢复下载的 zip 文件。

使用 IntentView 返回所有意图数据

创建、列出或获取意图时,意图数据会返回给调用方。默认情况下,此返回数据为缩写形式。 以下示例使用此默认值。

如需检索所有意图数据,必须将 IntentView 参数设置为 INTENT_VIEW_FULL。如需了解详情,请参阅意图类型方法。

创建意图

以下示例展示如何创建意图。如需了解详情,请参阅意图参考

REST

如需为代理创建意图,请对 intent 资源调用 create 方法。

在使用任何请求数据之前,请先进行以下替换:

  • PROJECT_ID:您的 Google Cloud 项目 ID

HTTP 方法和网址:

POST https://dialogflow.googleapis.com/v2/projects/PROJECT_ID/agent/intents

请求 JSON 正文:

{
  "displayName": "ListRooms",
  "priority": 500000,
  "webhookState": "WEBHOOK_STATE_UNSPECIFIED",
  "trainingPhrases": [
    {
      "type": "EXAMPLE",
      "parts": [
        {
          "text": "What rooms are available at 10am today?"
        }
      ]
    }
  ],
  "action": "listRooms",
  "messages": [
    {
      "text": {
        "text": [
          "Here are the available rooms:"
        ]
      }
    }
  ]
}

如需发送您的请求,请展开以下选项之一:

您应该收到类似以下内容的 JSON 响应:

intents 后面的路径段包含新的意图 ID。
