我有以下OpenStruct对象,但如果我叫的.class它是一个字符串。 我怎么把它放回一个OpenStruct对象?
[
#<OpenStruct source="hkepc.com", visits="8", visitBounceRate="37.5", avgTimeOnSite="199.375", pageviews="25", pageviewsPerVisit="3.125">,
#<OpenStruct source="1st-tag.co.uk", visits="6", visitBounceRate="100.0", avgTimeOnSite="0.0", pageviews="6", pageviewsPerVisit="1.0">,
#<OpenStruct source="facebook.com", visits="5", visitBounceRate="80.0", avgTimeOnSite="8.2", pageviews="6", pageviewsPerVisit="1.2">
]
一点点哈克,但我认为实现你的目标:
require 'ostruct'
string_array = '[
#<OpenStruct source="hkepc.com", visits="8", visitBounceRate="37.5", avgTimeOnSite="199.375", pageviews="25", pageviewsPerVisit="3.125">,
#<OpenStruct source="1st-tag.co.uk", visits="6", visitBounceRate="100.0", avgTimeOnSite="0.0", pageviews="6", pageviewsPerVisit="1.0">,
#<OpenStruct source="facebook.com", visits="5", visitBounceRate="80.0", avgTimeOnSite="8.2", pageviews="6", pageviewsPerVisit="1.2">
]'
string_array.gsub(/(\n|#<OpenStruct|\[|\]|\s+)/, '').split('>,').map do |attrs|
struct_attrs = attrs.split(',')
attrs = struct_attrs.inject({}) do |hash, elem|
hash[elem.split('=').first] = elem.split('=').last.gsub('"', '')
hash
end
OpenStruct.new(attrs)
end
