Ruby Google Custom Seach API从下一页获取结果 [英] Ruby Google Custom Seach API get results from next page

问题描述

下面的代码仅从Google分页的第一页获取结果...如何获得更多结果?

the code below is only getting the results from the first page of the google pagination... how to get more results?

require 'google/api_client'

# autenticação
client = Google::APIClient.new(:application_name => 'Ruby Drive sample',
      :application_version => '1.0.0', 
      :client_id => 'xxxxxxxxxxxxxxxx',
      :client_secret => 'xxxxxxxxxxxxxx',
      :authorization => nil)
search = client.discovered_api('customsearch')

# chama a API
response = client.execute(
  :api_method => search.cse.list,
    :parameters => {
      'q' => 'cafe',
      'key' => 'xxxxxxxxxxxx',
      'cx' => 'xxxxxxxxxxxxxxxx'
    }
)

# recebe a resposta em json
body = JSON.parse(response.body)
items = body['items']

# printa algumas informações...
items.each do |item|
  puts "#{item['formattedUrl']}"
end

推荐答案

在下一个请求中仅将nextPageToken用作参数，直到获得没有nextPageToken键的结果

Simply use the nextPageToken as a parameter in the next request until you get back a result without a nextPageToken key

next_page_token = body['nextPageToken']

response_page2 = client.execute(
  :api_method => search.cse.list,
  :parameters => {
    'nextPageToken' => next_page_token,
    'key' => 'xxxxxxxxxxxx',
    'cx' => 'xxxxxxxxxxxxxxxx'
  }
)
