Question

我正在尝试在Bot仿真器中运行默认的EchoBot，在配置了端点，AppID和App密码之后，我收到了POST 400 directline.postActivity错误。

我正在运行Bot Emulator Framework v4.4.1和Microsoft提供的C＃v4.4.4 EchoBot示例。当我在Visual Studio中构建项目时，它输出到本地主机上的端口3978。在仿真器中输入端点，ID和密码后，它开始连接。但是，该漫游器不会响应任何输入的文本。这是模拟器的日志：

我尝试过配置一个与仿真器说明的配置端点匹配的端点，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。我还尝试过重新安装模拟器，但这并没有改变任何内容。

已编辑

此外，模拟器配置为绕过本地地址的ngrok，并且本地替代设置为localhost。这些是默认设置，并且切换旁路选项或更改本地替代不能解决问题。

我尝试从appsettings.json文件中获取AppId和AppPassword，方法是将它们注释掉并保留为空字符串，但这两个都不能解决问题。

我还卸载并重新安装了Visual Studio，BotFramework SDK，模板和Bot仿真器，以查看是否可以解决任何问题，但它们不能解决问题。

最后一点，我尝试遵循有关使用模拟器的Microsoft BotFramework教程，任何尝试都会产生此结果。

更新

重新安装Bot Framework Emulator v4.4.2之后，问题仍然存在，但是出现了新的错误消息：

[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]Connecting to bots hosted remotely

incorrect.

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

我已确保它们确实匹配，但仍然出现此错误。

Answer 1

尝试从解决方案以及仿真器中删除应用程序ID，密码和ngrok，并在仿真器中仅添加localhost端点

Answer 2

您是代理人吗？我有完全一样的问题。我在代理服务器后面。相同的代码在我的Mac上确实可以很好地工作。但是在工作的Windows PC上却没有。我不知道这是否有帮助！我认为该错误是通用的，但最重要的是，它无法从login.microsoftonline.com获取JWTToken。
