Are there any open-source examples of using LocationLabs or Loc-Aid through Ruby?
LocationLabs and Loc-Aid are location aggregation services that expose REST APIs.开发者_StackOverflow社区 They currently offer Java, .NET and PHP SDKs. The API is not complex but, still, as a learning tool, it would be nice to have a Ruby tutorial or example to play with, extent, etc.
After further analysis, I built my application on Loc-Aid's infrastructure. Since there weren't many Ruby examples I could find, I'm sharing a snippet from my app.
# 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
