BotFramework Composer，在调用时出现404错误

Question

复制步骤：

步骤1：

选择Echo bot template，使用composer（mac上的1.0.0版安装表单DMG）创建一个bot

步骤2：

从当前回购中克隆回显技能样本： https://github.com/microsoft/BotBuilder-Samples/tree/master/samples/python/80.skills-simple-bot-to-bot

步骤3：

在本地运行该技能

步骤4：

连接到技能：

图中的端点是端口3980，但在最后一次尝试中，主bot是由编写器在当前bot上提供服务的。关键是我将回调URL设置为运行主bot的URL

步骤5：

在回显响应后，向未知意图对话框添加技能：

错误：

我在技术方面消除了一个错误。在调试该技能之后，我发现问题出在回调上，回调将404错误返回给发送活动时的技能

uring handling of the above exception, another exception occurred:

有人面临过同样的问题吗

Answer 1

您可以在documentation中看到，您的技能宿主端点需要以api/skills结束，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给技能的活动中的服务URL，这意味着它将是技能调用的任何对话API方法的基础URI。如果你的技能试图向一个不存在的URL发送请求，那么你应该得到404。Composer bot将把请求路由到以api/skills开头的路由，所以这就是您应该放在服务URL中的内容
