我正在遵循Node.js的Microsoft Bot Builder（SDK v3）的官方快速入门：使用Bot Builder SDK for Node.js创建机器人
1 -我创建了一个新项目
npm init
2 -然后
npm install --save botbuilder@3.13.1
3 -然后我创建了一个新文件“ app.js”
var builder = require('botbuilder');
var connector = new builder.ConsoleConnector().listen();
var bot = new builder.UniversalBot(connector, function (session) {
session.send("You said: %s", session.message.text);
});
但是当我运行node app.js时会引发以下错误：
var connector = builder.ConsoleConnector（）。listen（）;
TypeError： 无法读取未定义的属性“听”
答案 0 :(得分：0)
您尚未为机器人分配存储选项。最简单的选项（仅用于开发）是在内存存储中使用。您的代码应如下所示：
var builder = require('botbuilder');
// Bot Storage: Here we register the state storage for your bot.
// Default store: volatile in-memory store - Only for prototyping!
var inMemoryStorage = new builder.MemoryBotStorage();
var connector = new builder.ConsoleConnector().listen();
var bot = new builder.UniversalBot(connector, function(session) {
session.send("You said: %s", session.message.text);
}).set('storage', inMemoryStorage); // Register in memory storage
话虽如此，请注意，v3 SDK将在不久的将来被淘汰。建议您改用v4 Node SDK开始开发。首先，您可以参考文档here并查看示例代码here。
简而言之，在v4中，您将利用三个文件：index.js，bot.js和consoleAdapter.js。
index.js文件实质上是用于构建服务器，api等的
const path = require('path');
const {
ConsoleAdapter
} = require('./consoleAdapter');
// load environment variables from .env file.
const ENV_FILE = path.join(__dirname, '.env');
require('dotenv').config({
path: ENV_FILE
});
// Create the bot adapter, which is responsible for sending and receiving messages.
// We are using the ConsoleAdapter, which enables a bot you can chat with from within your terminal window.
const adapter = new ConsoleAdapter();
// Import our bot class.
const {
EchoBot
} = require('./bot');
const bot = new EchoBot();
// A call to adapter.listen tells the adapter to start listening for incoming messages and events, known as "activities."
// Activities are received as TurnContext objects by the handler function.
adapter.listen(async(context) => {
bot.onTurn(context);
});
// Emit a startup message with some instructions.
console.log('> Console EchoBot is online. I will repeat any message you send me!');
console.log('> Say "quit" to end.');
console.log(''); // Leave a blank line after instructions.
bot.js文件通常处理您的机器人的on [ActivityType]操作（例如onMessage（））。在更复杂的漫游器中，对话框会外推到自己的文件中。
class EchoBot {
async onTurn(context) {
// Check to see if this activity is an incoming message.
// (It could theoretically be another type of activity.)
if(context.activity.type === 'message' && context.activity.text) {
// Check to see if the user sent a simple "quit" message.
if(context.activity.text.toLowerCase() === 'quit') {
// Send a reply.
context.sendActivity(`Bye!`);
process.exit();
} else {
// Echo the message text back to the user.
return context.sendActivity(`I heard you say "${ context.activity.text }"`);
}
}
}
}
module.exports.EchoBot = EchoBot;
最后，consoleAdapter.js文件的任务是捕获控制台活动并将其转换为机器人。
'use strict';
var __importStar = (this && this.__importStar) || function(mod) {
if(mod && mod.__esModule) return mod;
var result = {};
if(mod != null)
for(var k in mod)
if(Object.hasOwnProperty.call(mod, k)) result[k] = mod[k];
result['default'] = mod;
return result;
};
Object.defineProperty(exports, '__esModule', {
value: true
});
const botbuilderCore = require('botbuilder-core');
const readline = __importStar(require('readline'));
