我正在尝试使用 Fog 列出 S3 存储桶的内容，但不断出现错误：
The request signature we calculated does not match the signature you provided. Check your key and signing method.

IAM 角色“S3BucketAccess”：

红宝石代码：
require 'rubygems'
require 'fog'
connection = Fog::Storage::AWS.new({:use_iam_profile => true})
p connection.directories
使用上述错误代码获取令人讨厌的错误消息/堆栈跟踪。
