Ruby 如何使用rails查找google plus一个计数（不需要按钮和g'；1图像）

我需要找到一个url的谷歌加一计数。 为了实现这一点，我遵循这一点

但是当我运行上面的代码时，它给了我以下错误

{"error"=>{"code"=>400, "message"=>"Invalid Value", "data"=>[{"domain"=>"global", "reason"=>"invalid", "message"=>"Invalid Value"}]}, "id"=>"p"}

当我跑的时候

curl -i -H 'Accept: application/json' -H 'Content-type: application/json' -X POST -d "{\"method\":\"pos.plusones.get\",\"id\":\"p\",\"params\":{\"nolog\":true,\"id\":\"http://www.google.com\",\"source\":\"widget\",\"userId\":\"@viewer\",\"groupId\":\"@self\"},\"jsonrpc\":\"2.0\",\"key\":\"p\",\"apiVersion\":\"v1\"}"  'https://clients6.google.com/rpc?key=AIzaSyCKSbrvQasunBoV16zDH9R33D88CeLr9gQ'

我明白了

    "message": "Invalid Value"
   }
  ]
 },
 "id": "p"
}

以下代码在ruby中工作

    require 'curb'
    require 'json'
    hash =  {method: "pos.plusones.get",id: "p",params: {nolog: true, id: "http://www.tomanthony.co.uk/", source: "widget", userId: "@viewer", groupId: "@self"}, jsonrpc: "2.0", key: "p", apiVersion: "v1"} 
    result=(Curl::Easy.http_post("https://clients6.google.com/rpc?key=AIzaSyCKSbrvQasunBoV16zDH9R33D88CeLr9gQ", 
hash.to_json) do |curl|
      curl.headers['Accept']='application/json'
      curl.headers['Content-Type']='application/json'
      curl.headers['Api-Version']='2.2'
    end)
    result=JSON.parse(result.body_str)
    count = result && result['result'] && result['result']['metadata'] && result['result']['metadata']['globalCounts'] && result['result']['metadata']['globalCounts']['count'] ? result['result']['metadata']['globalCounts']['count'].to_i : 0

我投了一个球来玩：

    require 'curb'
    require 'json'
    hash =  {method: "pos.plusones.get",id: "p",params: {nolog: true, id: "http://www.tomanthony.co.uk/", source: "widget", userId: "@viewer", groupId: "@self"}, jsonrpc: "2.0", key: "p", apiVersion: "v1"} 
    result=(Curl::Easy.http_post("https://clients6.google.com/rpc?key=AIzaSyCKSbrvQasunBoV16zDH9R33D88CeLr9gQ", 
hash.to_json) do |curl|
      curl.headers['Accept']='application/json'
      curl.headers['Content-Type']='application/json'
      curl.headers['Api-Version']='2.2'
    end)
    result=JSON.parse(result.body_str)
    count = result && result['result'] && result['result']['metadata'] && result['result']['metadata']['globalCounts'] && result['result']['metadata']['globalCounts']['count'] ? result['result']['metadata']['globalCounts']['count'].to_i : 0
