Bot Framework 和 LUIS 发送请求时出错答案

【问题标题】：Bot Framework and LUIS An error occurred while sending the requestBot Framework 和 LUIS 发送请求时出错
【发布时间】：2018-02-01 04:37:33
【问题描述】：

我将机器人框架升级到 3.13.0.3，但我的 LUIS 对话框停止工作。我的机器人启动，但是当我写下有关意图的词时，机器人再次显示初始消息并停留在此循环中。

我确实验证了应用 ID 和密钥，如果我从浏览器向 LUIS 发出请求，它可以正常工作，但从 bot 就像不发出请求一样。

我确实再次训练并发布了 LUIS 模型

在 Visual Studio 和 Azure 部署中，行为是相同的，当键入 LUIS 意图时，机器人会再次显示启动消息。 LUISIntent 是西班牙语“vacantes”或“registrar”

在升级之前，机器人可以正常工作并且 LUIS 对话框可以正常工作。

【问题讨论】：

你的问题是机器人一直在循环吗？如果是这样，原因是在您的GetUserNameAfter 函数中，您正在回发响应而不是等待下一个文本转到MessageReceived，所以在context.PostAsync 之后的函数末尾，添加context.Wait(this.MessageReceived);

标签： c# botframework azure-language-understanding

【解决方案1】：

您的对话框实现中有几个问题：

从 LuisDialog 继承的对话框

查看GitHub 上的LuisDialog 定义：您会看到对LUIS 的调用是在MessageReceived 方法中进行的。或者使用context.Wait(MessageReceived); 调用此方法，因为您正在覆盖StartAsync(IDialogContext context)，所以在您的对话框中从未使用过。

因此，您永远不会调用 LUIS 并进入与意图匹配的方法。

要纠正这一点，请在欢迎过程之后添加context.Wait(MessageReceived);，基本上是在GetUserNameAfter 的末尾。

方法结束

documentation 的一件重要事情：

确保所有对话方法都以处理下一条消息的计划结束。

所有 IDialog 方法都应以 IDialogStack.Call 完成， IDialogStack.Wait，或IDialogStack.Done。这些IDialogStack 方法通过传递给每个 IDialog 的 IDialogContext 公开方法。拨打IDialogStack.Forward并使用系统提示通过PromptDialog 静态方法将调用这些方法之一在他们的实施中。

如果我们按照您的对话流程进行操作，您会遇到几个问题：

GetUserNameAfter 方法执行结束，您向用户发布消息，然后您无需等待消息或结束对话
SendMayIHelp 方法执行结束，由多个方法调用（RecordCV、SearchJobAreaAfter when count > 0、GetInfo、...），您在其中向用户发布消息，然后您不在等待消息或结束对话
在SearchJob 和GetFeedback 中，您不应该在启动PromptDialog.Text 后return Task.CompletedTask;，因为此提示将在其他地方继续。将async 添加到您的方法定义中
FeedbackAfter 方法执行结束，您向用户发布消息，然后您无需等待消息或结束对话

【讨论】：

您好 Nicolas，感谢您提供的信息。我确实尝试过 context.Wait(MessageReceived);和 context.Done 但行为相同，当用户键入 LUIS 意图“vacantes”或“registrar”时，机器人再次显示启动消息。错误还是一样，异常：发送请求时出错。我正在使用 App ID LUIS 网页，以及 Azure 区域的 Web 链接中的 API Key southcentralus.api.cognitive.microsoft.com/luis/v2.0/apps/…
如果没有完整的代码来检查所有可能性，将很难提供更多帮助
Nicolas 我可以将代码发送给您或与 teamviewer 或 Skype 联系并查看代码吗？
