如何使用C# Core3.1在机器人框架v4中截取消息以进行日志记录

using Microsoft.Bot.Builder;
using Microsoft.Bot.Builder.Integration.AspNet.Core;
using Microsoft.Bot.Schema;

public class LoggingMiddleware : IMiddleware
{
    public async Task OnTurnAsync(ITurnContext turnContext, NextDelegate next, CancellationToken cancellationToken = default)
    {
        // 在这里进行消息的截取和日志记录
        var message = turnContext.Activity.Text;
        Console.WriteLine($"收到消息：{message}");

        // 调用下一个中间件或处理程序
        await next(cancellationToken);
    }
}

public class Startup
{
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        // ...

        app.UseBotFramework();

        // 添加自定义的中间件
        app.UseMiddleware<LoggingMiddleware>();

        // ...
    }
}
