node.js – AWS Lambda：模块初始化错误：TypeError

2019年7月20日 202次阅读

我正在尝试部署AWS lambda函数,我已经用express编写了代码：

码：

 var express = require('express');
    var bodyParser = require('body-parser');
    var lampress = require('lampress');
    var request = require('request');
    var app = express();

    app.set('port', (process.env.PORT || 5000));

    // Process application/x-www-form-urlencoded
    app.use(bodyParser.urlencoded({extended: false}));

    // Process application/json
    app.use(bodyParser.json());

    // Index route
    app.get('/', function (req, res) {
        res.send('Hello! I am a Chatbot designed to help you learn  Type "begin" to start a chat! You can type "begin" at any time to return to the first menu');
    });

    // for Facebook verification
    app.get('/webhook/', function (req, res) {
        if (req.query['hub.verify_token'] === 'xyz') {
            res.send(req.query['hub.challenge']);
        }
        res.send('Error, wrong token');
    });

    // Spin up the server
     app.listen(app.get('port'), function() {
        console.log('running on port', app.get('port'));
    });

    //figure out if your greeting text is working
    //need persistent menu?
    app.post('/webhook/', function (req, res) {
        getStarted();
        greetingText();
        messaging_events = req.body.entry[0].messaging;
        for (i = 0; i < messaging_events.length; i++) {

            event = req.body.entry[0].messaging[i];
            sender = event.sender.id;
            if (event.message && event.message.text) {
            //code
            }
            if (event.postback) {
            //code
            }
            console.log('********2');
        }
        res.sendStatus(200)
    });

    exports.handler = lampress(app, function() {
        console.log("Server has started");
    });

错误：

 module initialization error: TypeError
        at lampress (/var/task/node_modules/lampress/index.js:82:10)
        at Object.<anonymous> (/var/task/index.js:829:23)
        at Module._compile (module.js:409:26)
        at Object.Module._extensions..js (module.js:416:10)
        at Module.load (module.js:343:32)
        at Function.Module._load (module.js:300:12)
        at Module.require (module.js:353:17)
        at require (internal/module.js:12:17)*

我有适当的node_modules.为什么不这样做呢？

压缩拉链结构
    – > index.js
    – > node_modules文件夹.

的package.json：
“lampress”：“^ 1.1.1”

最佳答案 我认为你的问题是在exports.handler = lampress(…根据
lampress docs lampress()需要2个参数,第一个是端口号,第二个是服务器.你已经传入了第一个参数的服务器和一个第二个函数,所以lampress抛出一个TypeError

正确的代码是：

exports.handler = lampress(<your port number>, app);
