require 'soap/wsdlDriver'
以下通過對Google的服務請求,使用Google的一個服務,并使用了WSDL(Web Services Description Language)來完成.(前提是你擁有一個Google Web API的使用賬号,并儲存在主目錄的.goolge_key檔案中)
require 'cgi'
WSDL_URL = "http://api.google.com/GoogleSearch.wsdl"
soap = SOAP::WSDLDriverFactory.new(WSDL_URL).createDriver
query = 'pragmatic'
key = File.read(File.join(ENV['HOME'], ".google_key")).chomp
result = soap.doGoogleSearch(key, query, 0, 1, false,
nil, false, nil, nil, nil)
printf "Estimated number of results is %d.\n",
result.estimatedTotalResultsCount
printf "Your query took %6f seconds.\n", result.searchTime
first = result.resultElements[0]
puts first.title
puts first.URL
puts CGI.unescapeHTML(first.snippet)
