使用 botframework + botbuilder-linebot-connector + serverless(AWS lambda) + botbuilder-mongodb-storage 連 mongodb cluster 開發 LineBot 入門 2

https://github.com/Wolke/linebot-serverless-MongoDbStorage-LineConnector-typeScript-starter-Kit

我直接解擇這個架構好了

1. serverless.yml 這個就serverless 的設定，得配合我開在AWS 上的 mongo cluster ，才能讓 aws lambda 存取。http://wolke-codes.blogspot.tw/2018/01/serverless-aws-lambda-aws-mongodb.html
2. bot/bot.ts bot 的流程... 可以參考我在IT鐵人的不負責任教學：https://ithelp.ithome.com.tw/users/20046160/ironman/1510
3. handler.js :這個是serverless 的預設的 function 定義的地方。
   

   'use strict';
   
   var config = require("./conf");//讀取你的設定
   var bot_dailog = require("./bot/bot")//將bot 流程 require 進來。
   var botbuilder_linebot_connector_1 = require("botbuilder-linebot-connector");
   var botbuilder_mongodb_storage_1 = require("botbuilder-mongodb-storage");
   var builder = require('botbuilder');
   var connector = new botbuilder_linebot_connector_1.LineConnector({
     hasPushApi: false,
     // your line
     channelId: process.env.channelId || config.channelId,
     channelSecret: process.env.channelSecret || config.channelSecret,
     channelAccessToken: process.env.channelAccessToken || config.channelAccessToken
   });//產生connector
   
   var bot = new builder.UniversalBot(connector) //產生 bot
   
     .set("storage", new botbuilder_mongodb_storage_1.MongoDbStorage({
       DatabaseName: config.DatabaseName,
       collectionName: config.collectionName,
       mongoIp: config.mongoIp,
       mongoPort: config.mongoPort,
       // mongoIp: "ds125578.mlab.com",
       // mongoPort: "255xx",
       // username: config.username,
       // password: config.password
     }));
     bot_dailog.default(bot)//將bot流程套用
   
   
   
   module.exports.line = (event, context, callback) => {
     connector.serverlessWebhock(event) //記得加 connector.serverlessWebhock(event) 就可以了。
   
   
     const response = {
       statusCode: 200,
       body: JSON.stringify({
         message: 'Go Serverless v1.0! Your function executed successfully!',
         input: event,
       }),
     };
   
     callback(null, response);
   
     // Use this code if you don't use the http event with the LAMBDA-PROXY integration
     // callback(null, { message: 'Go Serverless v1.0! Your function executed successfully!', event });
   };
