創建 S3 存儲桶 nodejs 時出現 aws-sdk 問題

Question

我目前正在使用aws-sdk來列出和創建存儲桶。

我的代碼如下

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{

        }
    })
});

我用於這些的 AWS IAM 用戶策略如下。

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

問題是，每當我提交 http 請求時，請求都不會終止或返回有效響應。

舉個例子。

我得到以下用於創建名為sample-1的存儲桶

[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，沒有同名的存儲桶，我在這種情況下使用的區域是eu-west-1 。 任何人都知道為什么會發生這種情況以及為什么請求沒有被終止。

Answer 1

存儲桶名稱對 AWS 來說是全局的。 見下文

Amazon S3 存儲桶名稱必須在全球范圍內唯一。 如果您收到“Bucket name already exists”或“BucketAlreadyExists”錯誤，則必須使用不同的存儲桶名稱來創建存儲桶。 這些錯誤消息表明另一個 AWS 賬戶擁有同名的存儲桶。

您應該嘗試使用唯一的名稱。
