我使用Botframework v3创建了一个机器人，该机器人将对话记录到一个Azure SQL数据库中。它可以使用机器人模拟器来工作。僵尸程序记录的问题和用户响应记录在azure sql数据库中。
但是，当我使用Bot注册通道将Bot从Visual Studio部署到Azure时。 （我已经多次部署其他类型的机器人，并且通常可以正常工作）当我在（测试网络聊天）Azure门户中使用该机器人时，它失败了–收到消息“抱歉我的机器人有问题”和用户类型无法发送。
所发送的消息/用户键入的确实被记录在sql数据库中。但是，自动程序询问的问题不会记录在sql数据库中。

感谢帮助。我很久以来一直在试图解决这个问题，但不明白为什么它不起作用。

错误：“字符串或二进制数据将被截断。”
但是我只是在打单打招呼
任何建议...非常感谢您的任何帮助。谢谢
答案 0 :(得分：0)
我实际上曾经遇到过SQL截断错误，尽管不是在使用Bot Framework时遇到的。记录CHAR和VARCHAR列的最大长度非常重要，这样可以确保写入到这些列的所有内容都在限制范围内。如有必要，应先截断字符串，然后再将其发送到数据库。
确定了列的最大长度后，请在LogAsync方法中设置一个断点，以便在记录每个活动时可以查看每个活动的详细信息。您说您只是在输入诸如“ hello”之类的短消息，但请记住，登录失败的不是您的消息，而是机器人的消息。由于尚不清楚您的机器人在模拟器中运行时，还是在其他通道上运行时，您的机器人发送的消息之间在操作上有什么区别，因此请同时注意fromId和toId，特别是如果表中的这些列包含不同的长度。不同的渠道会生成不同的ID，在模拟器中，机器人的ID通常只有一位数字。
TL; DR：找出fromId表中toId和message和userChatLog列的最大长度，然后调试代码并查看值是当它破裂时。
