# Sample code from Programing Ruby, page 239
require 'soap/wsdlDriver'
以下通过对Google的服务请求,使用Google的一个服务,并使用了WSDL(Web Services Description Language)来完成.(前提是你拥有一个Google Web API的使用账号,并保存在主目录的.goolge_key文件中)
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)

本文介绍了一个使用Ruby语言调用Google搜索API的示例代码。通过该示例,读者可以了解到如何利用Ruby结合WSDL进行网络服务请求,以及如何解析返回的数据。
