ruby 以hash方式读取.rb文件

[WO浣熊OW]

Chef中的attribute file都是XXX.rb格式，有什么方法可以把这种XXX.rb格式的文件转换成.json格式的文件吗？
或者
像JSON.parse（）方法一样，把.rb文件读取成一种obj类型的hash。

如：

$test['apache']['httpd.conf'] = {
'ServerTokens' => "ProductOnly",
'deflate' => {
'DeflateCompressionLevel' => '1'
},
'KeepAlive' => "On",
'KeepAliveTimeout' => "5",
'ListenBackLog' => "511"
}

其中$test['apache']['httpd.conf']是key，
而{
'ServerTokens' => "ProductOnly",
'deflate' => {
'DeflateCompressionLevel' => '1'
},
'KeepAlive' => "On",
'KeepAliveTimeout' => "5",
'ListenBackLog' => "511"
}是value，依次递归这样读取。

请问有实现的方法吗？

怎么把大{}的value付给一个变量？

[WO浣熊OW]

$test['apache']['httpd.conf'] = {'ServerTokens' => "ProductOnly",'deflate' => {'DeflateCompressionLevel' => '1'},'KeepAlive' => "On",'KeepAliveTimeout' => "5",'ListenBackLog' => "511"} 请问以上这样的字符串，用ruby怎么将它转成hash类型的？
