将漫游器会话存储到Azure sql数据库。未记录启动响应

Question

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。 机器人记录的问题和用户响应记录在azure sql db中。

但是，当我使用Bot注册频道将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/用户键入的内容确实记录在sql数据库中。 但是，自动程序提出的问题不会记录在sql db中。

SqlActivityogger类：

public class SqlActivityLogger : IActivityLogger
    {
    SqlConnection connection;

    public SqlActivityLogger(SqlConnection conn)
    {
        this.connection = conn;
    }
    public async Task LogAsync(IActivity activity)
    {
        string fromId = activity.From.Id;
        string toId = activity.Recipient.Id;
        string message = activity.AsMessageActivity().Text;

        //when creating the sql database make sure you create a table userChatLog table in the db in portal.azure.com
        string insertQuery = "INSERT INTO userChatLog(fromId, toId, message) VALUES (@fromId,@toId,@message)";

        // Passing the fromId, toId, message to the the user chatlog table 
        SqlCommand command = new SqlCommand(insertQuery, connection);
        command.Parameters.AddWithValue("@fromId", fromId);
        command.Parameters.AddWithValue("@toId", toId);
        command.Parameters.AddWithValue("@message", message);



        // Insert to Azure sql database
        command.ExecuteNonQuery();

        //command.ExecuteNonQuery();
        //Debug.WriteLine("Insertion successful of message: " + activity.AsMessageActivity().Text);
    }
}

Global.asax中

 public class WebApiApplication : System.Web.HttpApplication
{
    SqlConnection connection = null;
    protected void Application_Start()
    {
        //setting up sql string connection string

        SqlConnectionStringBuilder sqlbuilder = new SqlConnectionStringBuilder();
        sqlbuilder.DataSource = "##########";
        sqlbuilder.UserID = "#####";
        sqlbuilder.Password = "#####";
        sqlbuilder.InitialCatalog = "######";

        connection = new SqlConnection(sqlbuilder.ConnectionString);
        connection.Open();
        Debug.WriteLine("Connection success");


        Conversation.UpdateContainer(builder =>
        {
            builder.RegisterType<SqlActivityLogger>().AsImplementedInterfaces().InstancePerDependency().WithParameter("conn", connection);
        });

        GlobalConfiguration.Configure(WebApiConfig.Register);
    }

    protected void Application_End()
    {

        connection.Close();
        Debug.WriteLine("Connection to database closed");
    }

}

            await context.PostAsync("This is the end of the form, you would give a final confirmation, and then start the ordering process as needed.");
        };

        return new FormBuilder<SandwichOrder>()
                .Message("Welcome to the simple sandwich order bot!")
                .OnCompletion(processOrder)
                .Build();
    }
};

感谢帮助。 我已经很长时间了试图解决这个问题，并且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...非常感谢您的帮助。 谢谢

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。 记下CHAR和VARCHAR列的最大长度非常重要，这样可以确保写入这些列的所有内容都在限制之内。 如有必要，您应先截断字符串，然后再将其发送到数据库。

确定列的最大长度后，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仿真器中运行时与其他通道运行时，您的机器人发送的消息之间在操作上有什么区别，因此fromId注意fromId和toId ，特别是如果表中的这些列具有不同的长度时。 不同的通道生成ID的方式也不同，在模拟器中，机器人的ID通常只有一个数字长。

TL; DR：找出userChatLog表中fromId和toId以及message列的最大长度，然后调试代码并查看中断时值的长度。
