问题描述
我正在尝试在使用节点时下载S3对象，并已问过上一个问题.代码如下.我将访问密钥凭据声明为环境变量，并尝试了我的帐户访问密钥以及IAm角色.我尝试生成多个密钥，配置文件，存储桶和文件，以及创建存储桶策略，所有这些都导致了以下堆栈跟踪.我是否正确调用了存储桶和文件对象，以及正确设置了我的凭据?在使用aws-sdk下载对象之前，是否还需要确保先进行其他一些政策或配置设置?谢谢！
I am trying to download an S3 object while using node, and have asked this previous question. Code is below. I am declaring my access key credentials as environment variables and have tried both my account access keys as well as an IAm role. I have tried generating multiple keys, profiles, buckets and files, as well as creating a bucket policy, all of which have resulted in the following stack trace below. Am I calling the bucket and file objects correctly, as well as setting up my credentials correctly? Is there some other policy or set of configurations I need to make sure set up first before using the aws-sdk to download objects? Thanks!
代码:
var AWS = require('aws-sdk');
var s3 = new AWS.S3();
AWS.config = new AWS.Config();
AWS.config.accessKeyId = "myAccessKey";
AWS.config.secretAccessKey = "mySecretAccessKey";
AWS.config.region = "us-east-1";
var params = { Bucket: "myBucket", Key: "fileName" }
s3.getObject(params, function(err, data) {
if (err) console.log(err, err.stack);
else console.log(data);
});
堆栈跟踪:

推荐答案
此问题是您在创建S3 Client之后设置"config".更改代码，使其看起来像这样:
This problem is that you are setting up "config" after creating the S3 Client. Change your code to look like this:
var AWS = require('aws-sdk');
AWS.config = new AWS.Config();
AWS.config.accessKeyId = "myAccessKey";
AWS.config.secretAccessKey = "mySecretAccessKey";
AWS.config.region = "us-east-1";
var s3 = new AWS.S3();
var params = { Bucket: "myBucket", Key: "fileName" }
s3.getObject(params, function(err, data) {
if (err) console.log(err, err.stack);
else console.log(data);
});
