Nodejs AWS SDK S3 生成预​​签名 URL [英] Nodejs AWS SDK S3 Generate Presigned URL

问题描述

我正在使用 NodeJS AWS 开发工具包来生成预先签名的 S3 URL.文档给出了一个 生成预签名 URL 的示例.

I am using the NodeJS AWS SDK to generate a presigned S3 URL. The docs give an example of generating a presigned URL.

这是我的确切代码(省略了敏感信息):

Here is my exact code (with sensitive info omitted):

const AWS = require('aws-sdk')

const s3 = new AWS.S3()
AWS.config.update({accessKeyId: 'id-omitted', secretAccessKey: 'key-omitted'})

// Tried with and without this. Since s3 is not region-specific, I don't
// think it should be necessary.
// AWS.config.update({region: 'us-west-2'})

const myBucket = 'bucket-name'
const myKey = 'file-name.pdf'
const signedUrlExpireSeconds = 60 * 5

const url = s3.getSignedUrl('getObject', {
    Bucket: myBucket,
    Key: myKey,
    Expires: signedUrlExpireSeconds
})

console.log(url)

生成的 URL 如下所示:

The URL that generates looks like this:

https://bucket-name.s3-us-west-2.amazonaws.com/file-name.pdf?AWSAccessKeyId=[access-key-omitted]&Expires=1470666057&Signature=[signature-omitted]

我正在将该 URL 复制到我的浏览器中并得到以下响应:

I am copying that URL into my browser and getting the following response:

<Error>
  <Code>NoSuchBucket</Code>
  <Message>The specified bucket does not exist</Message>
  <BucketName>[bucket-name-omitted]</BucketName>
  <RequestId>D1A358D276305A5C</RequestId>
  <HostId>
    bz2OxmZcEM2173kXEDbKIZrlX508qSv+CVydHz3w6FFPFwC0CtaCa/TqDQYDmHQdI1oMlc07wWk=
  </HostId>
</Error>

我知道存储桶存在.当我通过 AWS Web GUI 导航到此项目并双击它时，它会打开带有 URL 的对象并且工作正常:

I know the bucket exists. When I navigate to this item via the AWS Web GUI and double click on it, it opens the object with URL and works just fine:

https://s3-us-west-2.amazonaws.com/[bucket-name-omitted]/[file-name-omitted].pdf?X-Amz-Date=20160808T141832Z&X-Amz-Expires=300&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Signature=[signature-omitted]&X-Amz-Credential=ASIAJKXDBR5CW3XXF5VQ/20160808/us-west-2/s3/aws4_request&X-Amz-SignedHeaders=Host&x-amz-security-token=[really-long-key]

因此，我相信我使用 SDK 的方式一定有问题.

So I am led to believe that I must be doing something wrong with how I'm using the SDK.

推荐答案

Dustin,

您的代码正确，请仔细检查以下内容:

Your code is correct, double check following:

1. 您的存储桶访问策略.

1. Your bucket access policy.

您通过 API 密钥获得的存储桶权限.

Your bucket permission via your API key.

您的 API 密钥和秘密.

Your API key and secret.

您的存储桶名称和密钥.

Your bucket name and key.
