创建S3存储桶Node.js时AWS-SDK出现问题

如何解决创建S3存储桶Node.js时AWS-SDK出现问题

我目前正在使用aws-sdk来列出和创建存储桶。

我的代码如下

var AWS = require('aws-sdk');
const router = require('express').Router();

require('dotenv').config();

AWS.config.logger = console;

// AWS.config.update({region: process.env.AWS_REGION}); // AWS bucket region 
s3 = new AWS.S3({
    // apiVersion: '2006-03-01',accessKeyId: process.env.AWS_ACCESS_KEY_ID,secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,region: process.env.AWS_REGION
}); // s3 svc object

// Accepts Bucket Name,Bucket Created User/ Belonging Organization
router.post('/create',(req,res,next)=>{
    var bucketParams = {
        Bucket: req.body.bucket
    }
    console.log(process.env.AWS_ACCESS_KEY_ID);
    s3.createBucket(bucketParams,(err,data)=>{
        console.log("sample");
        if (err) {
            console.log("Error",err);
          } else {
            console.log("Success",data.Location);
          }
    })
});

router.get('/',next)=>{
    s3.listBuckets((err,data)=>{
        if(err){

        }else{

        }
    })
});

我用于这些策略的AWS IAM用户策略如下。

{
    "Version": "2012-10-17","Statement": [
        {
            "Effect": "Allow","Action": "s3:*","Resource": "*"
        }
    ]
}

问题是，每当我提交http请求时，该请求都不会终止或返回有效的响应。

例如。

我得到以下有关创建名为sample-1的存储桶的信息

[AWS s3 409 1.052s 0 retries] createBucket({
  Bucket: 'sample1',CreateBucketConfiguration: { LocationConstraint: 'eu-west-1' }
})
sample
Error BucketAlreadyExists: The requested bucket name is not available. The bucket namespace is shared by all users of the system. Please select a different name and try again.

}

最奇怪的是，没有相同名称的存储桶，而我在这种情况下使用的区域是eu-west-1。任何人都知道为什么会发生这种情况以及为什么请求没有被终止的任何线索。

解决方法

存储桶名称对于AWS是全局的。见下文

Amazon S3存储桶名称在全球范围内必须唯一。如果收到“存储桶名称已存在”或“ BucketAlreadyExists”错误，则必须使用其他存储桶名称来创建存储桶。这些错误消息表明另一个AWS账户拥有一个具有相同名称的存储桶。

您应该尝试使用唯一的名称。
