我用ruby去解析这个URL，报错：Invalid JSON string

代码如下:
<code>
def v2ex_api(path)
url = URI.parse("http://v2ex.appspot.com")
res = Net::HTTP.start(url.host, url.port) do |http|
http.get(path)
end
ActiveSupport::JSON.decode res.body
end
puts v2ex_api("/api/topics/latest.json").inspect
</code>

原来json的格式化输出也可以这么漂亮。
ruby好像是可以解析的

require 'rubygems'
require 'json'
require 'open-uri'

url = URI.encode("http://v2ex.appspot.com/api/topics/latest.json")
buffer = open(url).read
data = JSON.parse(buffer)
puts data.inspect

API输出中有很多"\n", 这样是有效的JSON么？
