太阳黑子：solr-空响应

Question

I'm trying to obtain response of solr for a given query. I've checked the solr query interface on localhost:8983 and its working fine, giving the required response to the queries. I want to select the productId field from each response and print it. Following is the code I'm using:

#!/usr/bin/ruby
# encoding: utf-8

require 'rubygems'
require 'solr'

solr = Solr::Connection.new('http://localhost:8983/solr')
response = solr.query('necklace')

puts "the response is:"
#puts response
puts "\n"
response.each do |hit|
    puts hit['productId'] 
end

But it does not print anything, my response seems to be empty. How can I fix this

Answer 1

尝试将第16行更改为：

  puts hit['productId']
