无法通过 aws-sdk 节点 js 连接到 AWS

Question

我是 AWS 开发工具包的新手，并试图按照那里的文档进行操作。 https://aws.amazon.com/developers/getting-started/nodejs/ 我正在尝试创建一个存储桶并在那里上传一些文本文件。但是我收到了下面提到的错误。

{ 错误：连接 ETIMEDOUT 52.216.206.51:443 在 TCPConnectWrap.afterConnect [as oncomplete] (net.js:1104:14) 消息：'连接 ETIMEDOUT 52.216.206.51:443', 错误号：'ETIMEDOUT'， 代码：“网络错误”， 系统调用：'连接'， 地址：'52.216.206.51', 端口：443， 地区：'us-east-1'， 主机名： 'node-sdk-sample-c58bc12a-70be-4578-9c18-1c815962653b.s3.amazonaws.com', 可重试：真， 时间：20

我尝试在 userid/.aws/credentials 下的凭证文件中提供凭证

[default]
aws_access_key_id = my cred...
aws_secret_access_key = my cred....

我也尝试在代码本身中提供凭据

AWS.config.update({accessKeyId: 'my cred', secretAccessKey: 'my secret key', region: 'us-east-1'});

`// Load the SDK and UUID
var AWS = require('aws-sdk');
var uuid = require('node-uuid');
AWS.config.update({accessKeyId: '......', secretAccessKey: '.....', region: 'us-east-1'});

var s3 = new AWS.S3();
var bucketName = 'node-sdk-sample-' + uuid.v4();
var keyName = 'hello_world.txt';
s3.createBucket({Bucket: bucketName}, function() {
  var params = {Bucket: bucketName, Key: keyName, Body: 'Hello World!'};
  s3.putObject(params, function(err, data) {
    if (err)
      console.log(err)
    else
      console.log("Successfully uploaded data to " + bucketName + "/" + keyName);
  });
});`

我能够解决这个问题。该问题与代理有关。我试图从防火墙后面访问它。配置代理设置后，我可以连接到 AWS。

var proxy = require('proxy-agent'); 
AWS.config.update({ httpOptions: { agent: proxy('ur proxy url') } });

const AWS = require('aws-sdk'); //require aws sdk library

var params = {
Bucket: awsBucketName,
Key: path + fileName,
Body: value.data
};

//s3 upload start
s3bucket.upload(params, (err, data) => {
if (err) {
  return reject(err);
}
return resolve(data.key);
});

//get signed url for downloading the uploaded file
const url = await s3bucket.getSignedUrl('getObject', {
  Bucket: awsBucketName,
  Key: key,
  Expires: 60*3
});
