【问题描述】：

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'
})

它可以工作，但显示错误消息：

C:\Sistemas\AM\nodemodules\aws-iot-device-sdk\common\lib\tls-reader.js:89 Uncaught TypeError: filesys.existsSync is not a function at webpackJsonp../nodemodules/aws- iot-device-sdk/common/lib/tls-reader.js.module.exports

我该如何解决这个问题？

【解决方案1】：

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());
  });

【解决方案2】：

这个错误有两个可能的原因，即，

Angular 版本 > 4 和
JsonP 中的缩进对齐问题

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: "******" 
});
