预建代理

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）。

注意：导入预建代理会创建新的代理。 如果您要在现有代理中添加预建代理功能，可以从新创建的预建代理中导出流，并将其导入到现有代理。

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：

1. 转到 Dialogflow CX 控制台。
2. 点击要在其中导入预建代理的项目。
3. 点击使用预建代理。
4. 点击相关代理，然后点击导入。
5. 选择所需的位置，然后点击创建。
6. 开始测试和自定义。

自定义导入的预建代理

1. 测试代理，使用模拟器了解它如何帮助用户完成工作。
2. 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。
3. 删除与您的用例不相关的任何流。
4. 根据您的业务需求修改代理对话和自定义实体。
5. 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：

1. 转到 Dialogflow CX 控制台。
2. 点击要在其中导入预建代理的项目。
3. 点击使用预建代理。

4. 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。

   

5. 请参阅预建代理的网络钩子子部分并复制源代码。

6. 前往 Google Cloud 控制台，然后在左侧面板中选择 Cloud Functions。

   

7. 点击要导入源代码的项目。

8. 点击创建函数。 如需详细说明，请参阅创建 Cloud Functions 函数文档。

9. 在源代码部分下，选择內嵌编辑器，然后粘贴复制的源代码。

10. 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。

11. 点击触发器，然后复制触发器网址。

12. 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。

13. 使用 Webhook 文档测试您的 Fulfillment。

金融服务代理

此模板可帮助最终用户使用其卡片、检查应用状态以及调查可疑扣款。

示例话语

• 我希望支付未结余额。
• 我的银行卡丢了，需要一张新卡。
• 我想举报我的支票账号中的一些可疑活动。
• 我的汽车贷款申请状态如何？
• 你的企业信用卡的年费是多少？

Webhook

Cloud Functions Webhook 执行以下操作：

• 验证最终用户的身份
• 提供示例余额、贷款状态和信用卡功能信息
• 模拟付款示例，包括验证付款金额和日期
• 控制营业时间
