Question

我在Rails 3中设置了我的S3帐户，如下所示：

AWS::S3::DEFAULT_HOST.replace "s3-eu-west-1.amazonaws.com"
#Set up AWS S3
AWS::S3::Base.establish_connection!(
    :access_key_id     => 'itsa',
    :secret_access_key => 'secret'

)
BUCKET='wetten'

但由于某种原因，它说我的文件不存在。我已经为S3中的文件提供了“Everyone”打开/下载权限。

在Rails控制台中，this file：

>> AWS::S3::S3Object.exists?('/xml/BWBR0001821.xml', 'wetten')
true

>> AWS::S3::S3Object.find('/xml/BWBR0001821.xml', 'wetten')
AWS::S3::NoSuchKey: No such key `/xml/BWBR0001821.xml'
    from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/aws-s3-0.6.3/lib/aws/s3/object.rb:177:in `find'
    from (irb):11
    from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.13/lib/rails/commands/console.rb:47:in `start'
    from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.13/lib/rails/commands/console.rb:8:in `start'
    from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.13/lib/rails/commands.rb:41:in `<top (required)>'
    from C:/Users/Maarten/RubymineProjects/wetten-api/script/rails:6:in `require'
    from C:/Users/Maarten/RubymineProjects/wetten-api/script/rails:6:in `<top (required)>'
    from -e:1:in `load'
    from -e:1:in `<main>'

怎么了？

更新：我注意到在object.rb中，AWS S3 gem（v0.6.3）执行以下操作：

bucket = Bucket.find(bucket_name(bucket), :marker => key.previous, :max_keys => 1)

其中key为'/xml/BWBR0001821.xml'，key.previous为'/xml/BWBR0001821.xmk' ......到底是什么？这对我来说似乎是个错误。

发现错误。显然，当通过第一个正斜杠时，find方法会混淆。使用xml/BWBR0001821.xml作为文件名可以使用：

>> AWS::S3::S3Object.find('xml/BWBR0001821.xml', 'wetten')
#<AWS::S3::S3Object:0x49387284 '/wetten/xml/BWBR0001821.xml'>

现有对象的NoSuchKey错误
