python - BotFramework Composer，技能回调时出现 404 错误

Question

重现步骤:

第 1 步:

使用 composer 创建一个机器人(v1.0.0 从 DMG 安装在 mac 上)，选择 Echo Bot 模板。

第 2 步:

从当前 repo 克隆 echo 技能示例: https://github.com/microsoft/BotBuilder-Samples/tree/master/samples/python/80.skills-simple-bot-to-bot

第 3 步:

在本地运行技能。

第四步:

连接到技能:

图片中的端点使用端口 3980，但在最后一次尝试时，主机器人由当前机器人上的 Composer 提供服务。重点是我将回调 URL 设置为运行主机器人的 URL。

第 5 步:

未知意图对话框添加技能，回显响应后:

错误:

解除技能面的错误。调试技能后，我发现问题出在回调中，该回调将 404 错误返回给发送事件的技能。

uring handling of the above exception, another exception occurred:

有人遇到同样的问题吗？

你可以在documentation中看到您的技能主机端点需要以 api/skills 结尾而不仅仅是 api :

Select Skills from the Composer menu. In the Skills page, if your skill is remote, enter <ngrok address>/api/skills in the Skill Host Endpoint field. If your skill is local, you should enter localhost:port/api/skills in the Skill Host Endpoint field.

技能主机端点用作发送到技能的事件中的服务 URL，这意味着它将成为技能调用的任何对话 API 方法的基本 URI。如果您的技能尝试向不存在的 URL 发送请求，那么您应该会收到 404。 Composer 机器人会将请求路由到以 api/skills 开头的路由所以这就是您应该放入服务 URL 的内容。
