【问题描述】：

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('/', (req, res, next)=>{
    s3.listBuckets((err, data)=>{
        if(err){

        }else{

        }
    })
});

我用于这些的 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，请求都不会终止或返回有效响应。

举个例子。

我得到以下内容来创建一个名为 sample-1 的存储桶

[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.

}

最奇怪的是没有同名的存储桶，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。

【解决方案1】：

存储桶名称对 AWS 来说是全局的。见下文

Amazon S3 存储桶名称必须在全球范围内唯一。如果您收到“Bucket name already exists”或“BucketAlreadyExists”错误，则必须使用不同的存储桶名称来创建存储桶。这些错误消息表明另一个 AWS 账户拥有同名的存储桶。

您应该尝试使用唯一的名称。
