Question

我正在使用.Net SDK for AWS。

我想将一个文件放入S3并使其内容可供公众阅读，我看到我可以使用“Grants”属性来执行此操作，但是我无法在联机文档中找到某些值的输入田野。

var request = new PutObjectRequest()
{
BucketName = "some-bucket",
Key = fileName,
FilePath = filePath,
StorageClass = new S3StorageClass("REDUCED_REDUNDANCY"),
ContentType = "text/csv",
Grants = new List<S3Grant>() {
new S3Grant() {
Grantee = new S3Grantee()
{
CanonicalUser = "Everyone",
DisplayName = "Everyone"
},
Permission = new S3Permission("open/download")}}
};

在上述请求中：

1）受助人“Everyone”只是我的猜测，那里的有效值是什么？

2）对于S3Permission，有什么效果值相当于我对“开放/下载”的猜测？

我理解我必须在桶级别向公众开放列表权限，我可以通过控制台做任何事情，我似乎无法找到有效的API请求参数。

在此轻松发布：

http://docs.aws.amazon.com/sdkfornet1/latest/apidocs/html/T_Amazon_S3_Model_S3CannedACL.htm

var request = new PutObjectRequest()
{
    BucketName = "some-bucket",
    Key = fileName,
    FilePath = filePath,
    StorageClass = new S3StorageClass("REDUCED_REDUNDANCY"),
    ContentType = "text/csv",
    CannedACL = S3CannedACL.PublicRead
};

这将上传文件，并使用公共读取权限进行设置。

如果你得到“拒绝访问”＃34;错误，确保你有＆＃34; PutObjectAcl＆＃34;您的IAM政策允许。

对于仍在寻找答案的任何人，添加 ACL：'public-read'属性即可解决问题。
