使用ruby aws-sdk V2指示是否配置了靜態網站

Question

我為靜態Web托管配置了許多S3存儲桶，我試圖使用Ruby aws-sdk遍歷列表，以打印出各種屬性，例如索引文檔，錯誤文檔，重定向規則等。

不幸的是，某些存儲桶未配置為靜態托管。 我需要跳過這些存儲桶，以免出錯。

我不知道如何檢測是否為靜態托管配置了存儲桶，因此以下代碼將引發錯誤。 見下文。

require 'aws-sdk'

s3 = Aws::S3::Resource.new
s3.buckets.take(3).each do |bucket|
  puts "Name = #{bucket.name}"
  puts "Index Document = #{bucket.website.index_document}"
end

由於未捕獲而返回的錯誤是...

The specified bucket does not have a website configuration (Aws::S3::Errors::NoSuchWebsiteConfiguration)

Answer 1

我決定走捷徑，只發現錯誤。

require 'aws-sdk'

s3 = Aws::S3::Resource.new

my_buckets = s3.buckets.map

my_buckets.each do |bucket|
  begin
    puts bucket.name
    puts bucket.website.error_document

  # if a website is not configured it's going to throw an error when you try to access bucket.website.error_document\
  # rescue the error, even though this seems like there should be a more elegant way to handle this.
  rescue Aws::S3::Errors::NoSuchWebsiteConfiguration => e
    puts e.message
  # Buckets that are just there to provide a redirect for www versions of the domain will also throw an error
  rescue Aws::S3::Errors::PermanentRedirect => e
    puts e.message
  rescue Exception => e
    puts e.message
  end
end
