是否有任何通过Ruby使用LocationLabs或Loc-Aid的开源示例？

Question

LocationLabs和Loc-Aid是公开REST API的位置聚合服务。他们目前提供Java，.NET和PHP SDK。这个API并不复杂，但作为一个学习工具，最好还是带一个Ruby教程或例子来玩，扩展等等。

经过进一步的分析，我在Loc-Aid的基础架构上构建了我的应用程序。由于我找不到很多Ruby示例，因此我正在分享我的应用中的一段代码。

# Get SAVON soap client locaid location services 
    # Parameters: 
    # - none 
    # Returns: SOAP client for locaid location services 
    def get_location_client 
    Savon::Client.new do 
     wsdl.document = LOCAID_CONFIG['use_local_wsdl'] ? 
     File.expand_path(LOCAID_CONFIG['get_location_wsdl'].to_s, ::Rails.root.to_s) : 
     LOCAID_CONFIG['get_location_wsdl'].to_s 
     wsdl.endpoint = LOCAID_CONFIG['get_location_endpoint'].to_s 
    end 
    end 


    # Strip the return result from locaid response as a hash 
    # Parameters: 
    # - raw_response: Raw response XMLfrom locaid services 
    # - response_name: Response name which wrap the response return result in locaid response XML 
    # Returns: Hash corresponding to the key "return" in locaid soap response hash. 
    # Sample Raw Response: 
    # {:subscribe_phone_response=>{:return=>{:error=>{:error_code=>"00001", :error_message=>"Invalid or inactive user"}, :transaction_id=>"14028251"}, 
    #  :"@xmlns:ns2"=>"http://webservice.portico.locaid.net/"}} 
    def strip_locaid_return(raw_response, response_name) 
    unless raw_response.to_hash.has_key?(response_name) 
     raise TropoExceptions::ExternalError 
    end 
    raw_response[response_name][:return] 
    end 

    # Get location from locaid by the caller id 
    # Parameters: 
    #  - @caller_id: Caller id get from scope value 
    # Returns: none 
    def location_from_locaid 
    client = get_location_client 
    client.http.read_timeout = LOCAID_CONFIG['get_location_timeout'].to_i 
    # Call locaider service to get location 
    response = client.request :wsdl, :get_locations_x do |soap| 
     soap.body = { 
      :login => LOCAID_CONFIG['login'], 
      :password => LOCAID_CONFIG['password'], 
      :class_id => LOCAID_CONFIG['class_id'], 
      :msisdn_list => ["1#{@caller_id}"], 
      :coor_type => "DECIMAL", 
      :location_method => LOCAID_CONFIG['location_method'], 
      :sync_type => "SYN", 
      :overage => "1" 
     } 
    end 

    result_hash = strip_locaid_return(response, :get_locations_x_response) 
    if result_hash.has_key?(:error) 
     raise TropoExceptions::ExternalError 
    end 

    yield result_hash[:location_response].is_a?(Array) ? 
     result_hash[:location_response][0] : 
     result_hash[:location_response] 

    rescue Savon::Error, Timeout::Error => e 
    logger.error e 
    yield nil 
    end 
end
