Microsoft 团队 echo bot 示例不断失败并出现“access_token”错误

Question

我遇到了非常一致的问题，因为它与我的团队机器人的 access_token 相关。我正在使用用 python 编写的“02.echo-bot”示例。

当我转到 Azure 门户 -> 应用程序注册 -> 我的应用程序 -> 证书和服务时，我拥有的唯一客户端密钥中的“值”与我的

APP_PASSWORD

文件中的

config.py

一致。我的

APP_ID

值也与我在“概述”页面上的应用程序（客户端）ID 的值一致。

我已经正确设置了 ngrok，将流量转发到由

app.py

启动的服务器，当我从机器人框架网页的“测试”选项卡发送消息时，我可以看到流量流动。

但是，每次我发送消息时，我都会看到以下错误：

根据我看过的其他文章，这个问题似乎与应用程序密码不正确有关；但是，我已经多次确认并仔细检查了这一点。我什至创建了一个新的客户端密钥来获取新的密钥，但它仍然给我完全相同的错误。

设置此测试似乎相对简单且配置更改最少，因此我不确定还有什么其他因素会对此做出贡献。

任何指点将不胜感激。

Answer 1

虽然除了通过问答解决问题之外似乎没有记录任何内容，但现在在删除应用程序 ID 和应用程序密码时可以使用。根据 BotFramework：机器人的 MSA appId 或密码不正确，我假设这些值在调试为空时必须保持为空。

Answer 2

对于 config.py 中的

MicrosoftAppPassword

，请验证您是否使用“值”作为密钥，而不是 Azure 应用程序注册证书和密钥页面中的

SecretID
