本文介绍了一种使用Ruby on Rails调用Google地图服务的方法，包括地理位置编码查询和展示地图等功能。通过具体的代码示例，展示了如何实现地址到经纬度的转换，并在网页上显示带有标记的地图。

调用一个 Google 的服务是比较简单的
下面代码比较乱是个沙盘测试
controller:

require 'net/http'
require 'soap/wsdlDriver'

def test
end
def lookup_who
     who = [{:login => 'webservice',:pwd =>'123456'}]
     who.each_with_index do |wh,index|
     authentication = get_code_by_soap(wh)
     end
end

def lookup_geocodes
    # your list of places. In a real app, this would come from the database,
    # and have more robust descriptions
    places = [
      {:address=>'555 Irving, San Francisco, CA',:description=>'Irving'},
      {:address=>'1401 Valencia St, San Francisco, CA',:description=>'Valencia'},
      {:address=>'501 Cole St, San Francisco, CA',:description=>'Cole'},
      {:address=>'150 Church st, San Francisco, CA',:description=>'Church'}
     ]

    # this loop will do the geo lookup for each place
    places.each_with_index do |place,index|
      # get the geocode by calling our own get_geocode(address) method
      geocode = get_geocode place[:address]

      # geo_code is now a hash with keys :latitude and :longitude
      # place these values back into our "database" (array of hashes)
      place[:latitude]=geocode[:latitude]
      place[:longitude]=geocode[:longitude]

    end

    #place the result in the session so we can use it for display
    session[:places] = places

    #let the user know the lookup went ok
    render :text=> 'Looked up the geocodes for '+places.length.to_s+
    ' address and stored the result in the session . . .'

end

def show_google_map
    # all we're going to do is loop through the @places array on the page
    @places=session[:places]
end

def testclient
    Net::HTTP.start('192.168.1.2', 80) { |http|
      response = http.post('/WebService2/Service1.asmx/authentication',
   'login=webservice&pwd=123456')
      puts response.body
    }
    render :text => "ok"
end

private

def get_code_by_soap(who)
    x=ActionWebService::Client::Soap.new('authentication',"http://192.168.1.2/WebService2/Service1.asmx")
    x
    puts "OK"
    #puts @results

end
def get_code(auth)

    login = auth[:login].to_s
    pass = auth[:pwd].to_s
    puts "start call service"
    # this is where we call the geocoding web service
    server = XMLRPC::Client.new2('http://192.168.1.2/WebService2/Service1.asmx')
    result = server.call2('authentication', 'webservice','123456')

    #logger.debug "Geocode call: "+result.inspect

    #return {:success=> true, :latitude=> result[1][0]['lat'],
    #    :longitude=> result[1][0]['long']}
    puts "OK"
    puts result
end

def get_geocode(address)
    logger.debug 'starting geocoder call for address: '+address
    puts address
    # this is where we call the geocoding web service
    server = XMLRPC::Client.new2('http://rpc.geocoder.us/service/xmlrpc')
    result = server.call2('geocode', address)
    logger.debug "Geocode call: "+result.inspect

    return {:success=> true, :latitude=> result[1][0]['lat'],
        :longitude=> result[1][0]['long']}
end
