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），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：

运行本地技能。

第 4 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作曲家提供服务。重点是我将回调 URL 设置为 URL，其中主要机器人运行.

第 5 步：

未知意图对话框添加技能，回显响应后：

错误：

我解除技能方面的错误。技能调试后我发现问题出在回调 returns 404 error back to the skill on sending activity.

uring handling of the above exception, another exception occurred:

有人遇到同样的问题吗？

您可以在 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.

技能主机端点在发送到技能的活动中用作服务 URL，这意味着它将成为技能调用的任何对话 API 方法的基础 URI。如果您的技能试图向不存在的 URL 发送请求，那么您应该会收到 404。 Composer bot 会将请求路由到以 api/skills 开头的路由，因此这就是您应该在服务中放置的内容 URL.
