AWS Lambda:模块初始化错误:TypeError

问题描述

我正在尝试部署AWS lambda函数，并且已经用express编写了代码:

I am trying to deploy AWS lambda function and I have written code in express:

代码:

 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.为什么不做这项工作.

I have proper node_modules in place. Why wont this work.

压缩的zip结构 -> index.js -> node_modules文件夹.

compressed zip structure --> index.js --> node_modules folder.

package.json:"lampress":"^ 1.1.1"

package.json:"lampress": "^1.1.1"

推荐答案

我认为根据 lampress文档 lampress()带有2个参数，第一个是端口号，第二个是服务器.您已经为第一个参数传递了服务器，为第二个参数传递了一个函数，所以lampress会抛出一个TypeError

I think your problem is at exports.handler = lampress(... as per the lampress docs lampress() takes 2 arguments, the first a port number and the second a server. You've passed in a server for the first argument and a function for the second, so lampress throws a TypeError

正确的代码是:

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