【问题标题】：saving user avatar on paperclip and Aws::S3::Errors::AccessDenied在回形针和 Aws::S3::Errors::AccessDenied 上保存用户头像

【问题描述】：

我正在尝试通过 Facebook 注册以使用回形针创建具有头像的用户，并在我的网站上使用 Amazon S3 来存储用户头像。我希望用户能够将头像添加到他们的个人资料中，但似乎我被拒绝访问。我已经查看并尝试了几种解决方案，但均未成功。

以下是我浏览器上的错误：

Aws::S3::Errors::AccessDenied in SessionsController#create
Access Denied

提取的源代码（第 19 行附近）：

        create(
        avatar: process_uri(auth['info']['image'] + "?width=9999"),
        email: auth['info']['email'],
        provider: auth['provider'],

in the commnad-line errors:

这里是 user.rb:

    validates_attachment_content_type :avatar, :content_type => /\Aimage\/.*\Z/

    default_scope { order('id DESC') }

    def self.sign_in_from_facebook(auth)
        find_by(provider: auth['provider'], uid: auth['uid'] ) || create_user_from_facebook(auth)
    end

    def self.create_user_from_facebook(auth)
        create(
        avatar: process_uri(auth['info']['image'] + "?width=9999"),
        email: auth['info']['email'],
        provider: auth['provider'],
        uid: auth['uid'],
        name: auth['info']['name'],
        gender: auth['extra']['raw_info']['gender'],
        date_of_birth: auth['extra']['raw_info']['birthday'],
        location: auth['info']['location'],
        bio: auth['extra']['raw_info']['bio']
        )
    end
end

听起来像是您的 S3 存储桶的权限问题，与您的代码无关。
