如何为nodejs aws-sdk配置caCert和代理，“错误：无法获取本地发行者证书”

如何解决如何为nodejs aws-sdk配置caCert和代理，“错误：无法获取本地发行者证书”

我已经成功地使用底部代码块配置了代理和证书文件，但是我仍然遇到以下证书错误。我已经在这个问题上停留了一段时间，请您帮我解决这个问题。

{ Error: unable to get local issuer certificate

    at emitNone (events.js:106:13)
    at TLSSocket.emit (events.js:208:7)

*通过PowerShell命令设置环境变量后，aws-cli可以正常工作

SETX AWS_CA_BUNDLE c：/projects/backend/tls-cabundle.pem

*我已使用以下命令更新了.npmrc文件，也尝试了使用-g标志。

npm配置设置cafile c：/projects/backend/tls-cabundle.pem
npm config set strict-ssl false

const AWS = require("aws-sdk");
const fs = require("fs");
const path = require("path");
const url = require("url");
const HttpsProxyAgent = require("https-proxy-agent");

const certs = [fs.readFileSync(path.join(__dirname,"tls-cabundle.pem"))];

const proxyOptions = {};
Object.assign(proxyOptions,url.parse("http://USERNAME:[e-mail]:8080"));
Object.assign(proxyOptions,{
  rejectUnauthorized: true,ca: certs,});

const creds = new AWS.Credentials({
  accessKeyId: "****************",secretAccessKey: "***********************",sessionToken: "**************************************************************",});
AWS.config.credentials = creds;

AWS.config.update({
  region: "eu-west-1",httpOptions: {
    agent: new HttpsProxyAgent(proxyOptions),},});

// Create S3 service object
const s3 = new AWS.S3({ apiVersion: "2006-03-01" });

// use aws-sdk S3 service object to list S3 Buckets as per https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html#listBuckets-property
s3.listBuckets(function (err,data) {
  if (err) console.log(err,err.stack);
  else console.log(data);
});
