从Golang REST API生成Amazon S3令牌

I'm writing a Golang REST API that needs to generate S3 tokens for users so that they can upload files to the specific folder inside a bucket.

This is what I need to implement:

Method: GET
Endpoint: myapp.com/images/:imageid/token
Description: Return 2 tokens so that the user can upload files to the S3 
             bucket related to the image ID parameter.

I'm using the Golang echo framework. And I'm not really sure how to implement this functionality.

Should this be done via the AWS SDK or does Amazon offer other ways of programmatically generrating tokens?

    To generate tokens for users to upload files directly to s3, you can use pre-signed URLS.

    After generating a pre-signed URL, return that to the user and the calling application can use that to upload the file.

    This example from the link above should be about what you're looking for:

    svc := s3.New(session.New(&aws.Config{Region: aws.String("us-west-2")}))
    req, _ := svc.PutObjectRequest(&s3.PutObjectInput{
        Bucket: aws.String("myBucket"),
        Key:    aws.String("myKey"),
    })
    str, err := req.Presign(15 * time.Minute)
    
    log.Println("The URL is:", str, " err:", err)
