當使用回形針將文件上傳到亞馬遜時讀取時拒絕訪問

Question

當在S3上讀取文件時產生錯誤Access Denied。設置回形針：

has_attached_file :doc, 
       storage:  :s3, 
       s3_permissions: "public-read", 
       bucket: "my-app", 
       path:   ':message_subscriber/:class/:id_partition/:filename' 

我得到的網址，以便：@model.doc.url

如何解決讀取參數public-read？

Answer 1

確保在您的配置中設置了AWS access_key_id和secret_access_key。而且，您還需要確保您的用戶帳戶在AWS IAM控制檯中設置了Access Policy。
