azure - 机器人模拟器错误：POST 400 directline.postActivity

问题描述

我正在尝试在 Bot Emulator 中运行默认 EchoBot，在配置端点、AppID 和 App 密码后，我收到 POST 400 directline.postActivity 错误。

我正在运行 Bot Emulator Framework v4.4.1，以及 Microsoft 提供的 C# v4.4.4 EchoBot 示例。当我在 Visual Studio 中构建项目时，它会输出到 localhost 上的端口 3978。在模拟器中输入端点、ID 和密码后，它开始连接。但是，机器人不会响应任何输入的文本。这是来自模拟器的日志：

我尝试过配置一个与模拟器状态匹配的端点，但这只会导致无限连接消息，甚至不允许我向机器人输入任何文本。我也尝试过重新安装模拟器，但这并没有改变任何东西。

已编辑

此外，模拟器配置为绕过 ngrok 获取本地地址，并且本地覆盖设置为 localhost。这些是默认设置，切换旁路选项或更改本地覆盖并不能解决问题。

我已经尝试从 appsettings.json 文件中获取 AppId 和 AppPassword ，方法是将它们注释掉并将它们保留为空字符串，但都没有解决问题。

我还卸载并重新安装了 Visual Studio、BotFramework SDK、模板和 Bot Emulator，看看是否能解决任何问题，但他们没有。

最后一点，我已经尝试按照 Microsoft BotFramework 教程使用模拟器，任何尝试都会产生这个结果。

更新

重新安装Bot Framework Emulator v4.4.2后，问题依旧，但是出现了新的错误信息：

[14:03:32]Emulator listening on http://localhost:61486
[14:03:32]ngrok not configured (only needed when connecting to remotely 
hosted bots)

[14:03:32]POSTdirectline.conversationUpdate
[14:03:32]POST200directline.startConversation

我已确保它们确实匹配，但我仍然收到此错误。
