Question

我创建了一个这样的插件：

var awsIot = require('aws-iot-device-sdk')
var device = awsIot.device({
keyPath: 'xxxxxx,
certPath: 'xxxxxx,
caPath: 'xxxxxx',
clientId: 'xxxxx', 
region: 'xxxxxx',
host: 'xxxxxxxxxx.amazonaws.com'
})

可行，但会显示错误消息：

C：\ Sistemas \ AM \ nodemodules \ aws-iot-device-sdk \ common \ lib \ tls-reader.js：89 Uncaught TypeError：filesys.existsSync不是webpackJsonp的函数../ nodemodules / aws- IOT装置-SDK /普通/ LIB / TLS-reader.js.module.exports

我该如何解决这个问题？

Answer 1

此错误有两个可能的原因，即 1.角版本是否大于4，并且 2.在JsonP中缩进对齐问题

var awsIot = require('aws-iot-device-sdk');

var device = awsIot.device({
    endpoint: 'https://******************.iot.eu-central-1.amazonaws.com',
    keyPath: '../aws/************-private.pem.key',
    certPath: '../aws/***********-certificate.pem.crt',
            caPath: '../aws/***********-public.pem.key',
    clientId: "******************",
            region: "******" 
});

Answer 2

var awsIot = require('aws-iot-device-sdk');

//
// Replace the values of '<YourUniqueClientIdentifier>' and '<YourCustomEndpoint>'
// with a unique client identifier and custom host endpoint provided in AWS IoT.
// NOTE: client identifiers must be unique within your AWS account; if a client attempts 
// to connect with a client identifier which is already in use, the existing 
// connection will be terminated.
//
var device = awsIot.device({
   keyPath: 'xxxxxxxxx-private.pem.key',
  certPath: 'xxxxxxxxx-certificate.pem.crt',
    caPath: 'rootCA.pem',
  clientId: 'MyConnect',
   host: 'xxxxxxx.iot.ap-southeast-1.amazonaws.com'
});

//
// Device is an instance returned by mqtt.Client(), see mqtt.js for full
// documentation.
//
device
  .on('connect', function() {
    console.log('connect');
    //device.subscribe('topic_1');
    device.publish('MyConnectPolicy', JSON.stringify({ test_data: 'NodeJS server connected...'}));
  });

device`enter code here`
  .on('message', function(topic, payload) {
    console.log('message', topic, payload.toString());
  });

Nuxt + IOT（aws-iot-device-sdk）
