我正在尝试使用厨师从AWS s3桶下载文件（厨师超市提供的aws食谱）。我一直收到以下错误消息。
Net::HTTPServerException
------------------------
remote_file[/etc/chef/encrypted_data_bag_secret] (/var/chef/cache/cookbooks/aws/providers/s3_file.rb line 36) had an error: Net::HTTPServerException: 400 "Bad Request"
出于身份验证的目的，我正在使用IAM角色。我可以使用aws s3命令行下载相同的文件。这意味着角色本身没有问题。
详细日志如下。

aws_s3_file可能存在一些错误。我写了下面的方法来解决这个问题。
include_recipe 'aws'
require 'aws-sdk'
client = Aws::S3::Client.new(region: 'us-east-1')
bucket = client.get_object(bucket:'app-chefconfig', key: 'encrypted_data_bag_secret')
# Read content to variable
file_content = bucket.body.read
# Log output (optional)
Chef::Log.info(file_content)
# Write content to file
file '/etc/chef/encrypted_data_bag_secret' do
owner 'root'
group 'root'
mode '0755'
content file_content
action :create
end
