预建代理是由对话代理 (Dialogflow CX) 提供的一组常见代理 案例 您可以这些代理为基础,构建对话。在对话代理 (Dialogflow CX) 中,您会找到不同行业、 (如电信、金融服务、医疗保健、零售和旅游)。 生成式预建代理也提供受限访问权限,可演示使用生成式功能实现的常见用例。
预建代理包含针对其用例的意图和实体,但您需要修改示例路由组和 Fulfillment(如适用)。
限制
存在以下限制:
- 预建代理目前仅支持英语。
导入预建代理
如需将预建代理导入您的项目中,请执行以下操作:
- 转到 Dialogflow CX 控制台。
- 点击要在其中导入预建代理的项目。
- 点击使用预建代理。
- 点击相关代理,然后点击导入。
- 选择所需的位置,然后点击创建。
- 开始测试和自定义。
自定义导入的预建代理
- 测试代理,使用模拟器了解它如何帮助用户完成工作。
- 点击左侧窗格中的管理标签页,然后点击测试用例以查看覆盖率和示例脚本。如需了解详情,请参阅测试用例文档。
- 删除与您的用例不相关的任何流。
- 根据您的业务需求修改代理对话和自定义实体。
- 如果存在 Webhook 源代码,请参阅修改 Webhook 代码。
修改 Webhook 代码
部分预建代理会利用 Webhook。原始 Webhook 源代码使用 Node.js,并托管在 Google 的内部 Cloud Functions 项目中。
如需在您自己的 Cloud Functions 项目中使用和修改此代码,请按照后续说明操作:
- 转到 Dialogflow CX 控制台。
- 点击要在其中导入预建代理的项目。
- 点击使用预建代理。
点击相关代理,然后点击文档链接,系统即会将您转到本文的相关预建代理部分。
请参阅预建代理的网络钩子子部分并复制源代码。
前往 Google Cloud 控制台,然后在左侧面板中选择 Cloud Functions。
点击要导入源代码的项目。
点击创建函数。 如需详细说明,请参阅创建 Cloud Functions 函数文档。
在源代码部分下,选择內嵌编辑器,然后粘贴复制的源代码。
依次点击来源和修改,以根据业务规则更改逻辑。完成后,点击部署。
点击触发器,然后复制触发器网址。
替换代理中的该触发器网址,方法是依次转到管理 > 网络钩子,然后选择要将新网址粘贴到的网络钩子。将触发器网址粘贴到标记为网络钩子网址的字段中。点击保存。
使用 Webhook 文档测试您的 Fulfillment。
