在团队机器人中遇到多个404和405错误

问题描述

我正在对我目前正在开发的Teams Bot进行一些调查。当我查看Application Insights时，看到很多404错误，在某些其他情况下，出现405错误-我试图了解是否错过了任何内容。

我将App Service设置为“ Always On”，因此我假设它每5分钟轮询一次该服务，以防止其空闲。但是，我看到很多404错误，特别是指向 GET / 端点，在其他情况下也指向405错误，这指向了 api / messages 端点。

我在环境变量中设置了应用程序ID和应用程序密码，我也使用Cosmos DB设置了存储，如下面的index.js文件所示。我还检查了Teams清单以确保它指向Bot ID，并且最近还添加了bot域，以查看是否有区别。

const restify = require('restify');
const path = require('path');

// Import required bot services.
// See https://aka.ms/bot-services to learn more about the different parts of a bot.
const { BotFrameworkAdapter,ConversationState,UserState } = require('botbuilder');

// Import required services for bot telemetry
const { ApplicationInsightsTelemetryClient,TelemetryInitializerMiddleware } = require('botbuilder-applicationinsights');
const { TelemetryLoggerMiddleware,NullTelemetryClient } = require('botbuilder-core');

// Import our custom bot class that provides a turn handling function.
const { DialogBot } = require('./bots/dialogBot');
const { ProvisioningProfileDialog } = require('./dialogs/provisioningProfileDialog');

// Read environment variables from .env file
const ENV_FILE = path.join(__dirname,'.env');
require('dotenv').config({ path: ENV_FILE });

// Create the adapter. See https://aka.ms/about-bot-adapter to learn more about using information from
// the .bot file when configuring your adapter.
const adapter = new BotFrameworkAdapter({
    appId: process.env.MicrosoftAppId,appPassword: process.env.MicrosoftAppPassword
});

// Define the state store for your bot.
const { CosmosDbPartitionedStorage } = require('botbuilder-azure');

const cosmosStorage = new CosmosDbPartitionedStorage({
    cosmosDbEndpoint: process.env.CosmosDbEndpoint,authKey: process.env.CosmosDbAuthKey,databaseId: process.env.CosmosDbDatabaseId,containerId: process.env.CosmosDbContainerId,compatibilityMode: false
});

// Create conversation state with storage provider.
const conversationState = new ConversationState(cosmosStorage);
const userState = new UserState(cosmosStorage);

// Create the main dialog.
const dialog = new ProvisioningProfileDialog(userState);
const bot = new DialogBot(conversationState,userState,dialog);
dialog.telemetryClient = telemetryClient;

// Catch-all for errors.
const onTurnErrorHandler = async (context,error) => {
    // This check writes out errors to console log .vs. app insights.
    // NOTE: In production environment,you should consider logging this to Azure
    //       application insights.
    console.error(`\n [onTurnError] unhandled error: ${ error }`);

    // Send a trace activity,which will be displayed in Bot Framework Emulator
    await context.sendTraceActivity(
        'OnTurnError Trace',`${ error }`,'https://www.botframework.com/schemas/error','TurnError'
    );

    // Send a message to the user
    await context.sendActivity('The bot encountered an error or bug.');
    await context.sendActivity('To continue to run this bot,please fix the bot source code.');
    // Clear out state
    await conversationState.delete(context);
};

// Set the onTurnError for the singleton BotFrameworkAdapter.
adapter.onTurnError = onTurnErrorHandler;

// Add telemetry middleware to the adapter middleware pipeline
var telemetryClient = getTelemetryClient(process.env.InstrumentationKey);
var telemetryLoggerMiddleware = new TelemetryLoggerMiddleware(telemetryClient);
var initializerMiddleware = new TelemetryInitializerMiddleware(telemetryLoggerMiddleware);
adapter.use(initializerMiddleware);

// Creates a new TelemetryClient based on a instrumentation key
function getTelemetryClient(instrumentationKey) {
    if (instrumentationKey) {
        return new ApplicationInsightsTelemetryClient(instrumentationKey);
    }
    return new NullTelemetryClient();
}

// Create HTTP server.
const server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3978,function() {
    console.log(`\n${ server.name } listening to ${ server.url }.`);
    console.log('\nGet Bot Framework Emulator: https://aka.ms/botframework-emulator');
    console.log('\nTo talk to your bot,open the emulator select "Open Bot"');
});

// Listen for incoming requests.
server.post('/api/messages',(req,res) => {
    adapter.processActivity(req,res,async (context) => {
        // Route the message to the bot's main handler.
        await bot.run(context);
    });
});

虽然Bot大部分情况下运行正常，但我是否错过了一些带有这些错误的内容，或者这是预期的行为，因为它正在轮询响应？

预先感谢

解决方法

1. 您的漫游器还包含网页吗？节点样本不是.NET samples do。如果没有，那么当然会收到404。我倾向于同意您的看法，这可能是轮询的原因。
2. 通常（特别是从模板或示例创建时），不处理bot到/ api / messages的GET端点。一切都通过POST处理。
