使用Koa2建立LINE-Bot Server

所需套件

• crypto
• request
• request-promise
• fs
• 需將lib資料夾及.env檔案複製至專案目錄之下，並更改.env（channelSecret、lineBotToken)
• 將package.json dependencies 所需套件及版本複製至專案內部的package.json

koa2 framework 建立Server 並加入LINE-Bot Middleware

const koa = require('koa');
const Router = require('koa-router');
const bodyParser = require('koa-bodyparser');
//使用.env檔的參數
const dotenv = require('dotenv').load();
const linebot = require('./lib/linebot.js');

const app = new koa();
const router = Router();
const channelSecret = process.env.channelSecret;
const lineBotToken = process.env.lineBotToken;

app.use(bodyParser());

router.post('/webhooks', async (ctx, next) => {

});

app
    .use(linebot.middleware(channelSecret))
    .use(router.routes());

const server = app.listen(process.env.PORT || 8080, function () {
    const port = server.address().port;
    console.log("App now running on port", port);
});

功能

1. auto response text

example

const responseText = require('./lib/example/responseText.js');
router.post('/webhooks', async (ctx, next) => {
    let events = ctx.request.body.events;
    data = await responseText.responseText(events, lineBotToken, {
        '哈囉': '你好阿',
        '晚安': '晚安'
    });
    ctx.body = data;
});

2. sticker

sticker list

example

const sticker = require('./lib/example/sticker.js');
router.post('/webhooks', async (ctx, next) => {
    let events = ctx.request.body.events;
    data = await sticker.sticker(events, lineBotToken, 11537, 52002734);
    ctx.body = data;
});

3. image

property	Description
originalContentUrl	https images url Max: 4096 x 4096 Max: 1 MB
previewImageUrl	https images url Max: 240 x 240 Max: 1 MB

example

const image = require('./lib/example/image.js');
router.post('/webhooks', async (ctx, next) => {
    let events = ctx.request.body.events;
    data = await image.image(events, lineBotToken, "https://i.imgur.com/slkvDvQ.jpg", "https://i.imgur.com/8206ST0.png");
    ctx.body = data;
});

4. confirm

example

const confirm = require('./lib/example/confirm.js');
router.post('/webhooks',async (ctx, next) => {
    let events = ctx.request.body.events;
    data = await confirm.confirm(events,lineBotToken);
    ctx.body = data;
});

5. richMenu

example

const richMenu = require('./lib/example/richMenu.js');
router.get('/create', async (ctx) => {
    //create rich menu
    let createDefaultRichMenu = await richMenu.createRichMenu(lineBotToken);
    let richMenuId = createDefaultRichMenu.richMenuId;
    console.log(richMenuId);
    // upload rich menu image
    let uploadRichMenuImageData = await richMenu.uploadRichMenuImage(richMenuId, `${__dirname}/public/img/test.png`, lineBotToken);
    console.log(uploadRichMenuImageData);
    // Set default rich menu
    let setDefaultRichMenuData = await richMenu.setDefaultRichMenu(richMenuId, lineBotToken);
    ctx.body = setDefaultRichMenuData;
});

6. URL

example

const url = require('./lib/example/url.js');
router.post('/webhooks', async (ctx, next) => {
    let events = ctx.request.body.events;
    data = await url.url(events, lineBotToken);
    ctx.body = data;
});
