机器人抛出异常时没有日志

Question

我们有一个 ASP.Net Core v4 机器人部署到 Azure。在 Azure 中使用测试功能时它工作正常。然后我们部署到 MS Teams。它可以找到，除了每条消息后跟另一条消息说 "Sorry, it looks like something went wrong." 该消息通常在抛出异常时发送。我尝试去 Azure 查看日志，但它没有记录任何内容。

我们的代码中确实有 logger.LogError($"Exception caught : {exception.Message}");，我认为它会在生产时将其记录在某处。所以我为机器人打开了 Application Insights，但它没有记录任何异常。我尝试从 Web 服务器流式传输日志，但在抛出异常时它不会记录任何内容。

我尝试从 "Application logs" 和 "Web server logs"

查看应用程序日志

这是处理错误的代码：

public AdapterWithErrorHandler(IConfiguration configuration, ILogger<BotFrameworkHttpAdapter> logger, ConversationState conversationState = null)
    : base(configuration, logger)
{
    OnTurnError = async (turnContext, exception) =>
    {
        // Log any leaked exception from the application.
        logger.LogError($"Exception caught : {exception.Message}");

        // Send a catch-all apology to the user.
        var errorMessage = MessageFactory.Text(ErrorMsgText, ErrorMsgText, InputHints.ExpectingInput);
        await turnContext.SendActivityAsync(errorMessage);

        if (conversationState != null)
        {
            try
            {
                // Delete the conversationState for the current conversation to prevent the
                // bot from getting stuck in a error-loop caused by being in a bad state.
                // ConversationState should be thought of as similar to "cookie-state" in a Web pages.
                await conversationState.DeleteAsync(turnContext);
            }
            catch (Exception e)
            {
                logger.LogError($"Exception caught on attempting to Delete ConversationState : {e.Message}");
            }
        }
    };
}

这里是我们的机器人的应用程序服务的日志设置：

@JohnGardner 是正确的。 Botframework catches all errors，因此您不会可能不会在典型的 Azure 应用服务日志记录中看到它们。

@VinodkumarG 也是正确的，您可以在

中看到 logger.LogError($"Exception caught : {exception.Message}"); 生成的错误

您实际上应该能够在日志流 > 应用程序日志中看到这个

我将此添加到我的机器人中：

我们目前推荐的方法是使用 Application Insights。您可以使用 Sample 21.Corebot-App-Insights as a guide. The primary modifications are how it adds App Insights in its Startup.cs:

            services.AddSingleton<MainDialog>();

            // Create the bot as a transient. In this case the ASP Controller is expecting an IBot.
            services.AddTransient<IBot, DialogAndWelcomeBot<MainDialog>>();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
