ruby - open_http: 403 禁止 (OpenURI::HTTPError)

Question

我正在尝试使用以下脚本从我的 Google+ API 中提取数据:

require 'open-uri'
require 'json'

google_api_key = 'put your google api key here'
page_id = '105672627985088123672'

data = open("https://www.googleapis.com/plus/v1/people/#{page_id}?key=#{google_api_key}").read    
obj = JSON.parse(data)

puts obj['plusOneCount'].to_i

但是，我一直收到这个错误:

/Users/xng/.rvm/rubies/ruby-1.9.2-p320/lib/ruby/1.9.1/open-uri.rb:346:in `open_http': 403 Forbidden (OpenURI::HTTPError)

我不确定这里出了什么问题，任何帮助都会很棒。

Answer 1

问题看起来是您的 google API key 与 google 在其服务器中拥有的 key 不匹配。因此，您需要确保您使用的是正确的 key 。它是私有(private)服务还是免费服务？
