amazon-web-services - aws s3 put 方法参数由 goamz

Question

之前我使用的是 "launchpad.net/goamz/s3"但是对于我的新项目，我正在使用 "github.com/goamz/goamz/s3".并且桶的 put 方法发生了变化，现在它多了一个参数“选项”

region := aws.USEast2
connection := s3.New(AWSAuth, region)
bucket := connection.Bucket("XXXXX") // change this your bucket name
path := "mypath" // this is the target file and location in S3
//Save image to s3
err = bucket.Put(path,user_content,content_type, s3.ACL("public-read"), options)

上面是我的代码。您能帮我了解选项中的预期内容以及我如何获得它的值(value)吗？

Answer 1

选项在 s3.go 中定义:

type Options struct {
    SSE              bool
    Meta             map[string][]string
    ContentEncoding  string
    CacheControl     string
    RedirectLocation string
    ContentMD5       string
    // What else?
    // Content-Disposition string
    //// The following become headers so they are []strings rather than strings... I think
    // x-amz-storage-class []string
}

这些选项在 official S3 api docs 中有详细记录.

在最简单的情况下，您可以不传递任何内容。例如:bucket.Put(path,user_content,content_type, s3.ACL("public-read"), s3.Options{})
