Create proof of concept

[jolevesq]

• [x] Create Lamda function and API gateway
• [x] Call API with dummy request
• [x] From Lamda, call Geoname API
• [x] Return json (not parsed)

To showcase the proof of concept, in the public folder, create a basic HTML page who will take the user input then sow on the page the JSON response. Next step will be to implement the github gh-pages so we can have a live demo from the repository.

Next step would be to create the AWS blocks (API Gateway, Lamda function, ...) and implement the basic functionalities in the py file.

Once done, we have the POC. We will validate the structure of our blocks and code then create the Cloud Formation script to automatically generate the AWS block.

Then we will work on the wrapper/schema, then adding new source of geolocation.

@David-Henandez-nrcan Once you receive the JSON response from GeoNames API trough our AWS API, please add the url to this issue. Thanks

At this point. There is not HTML page to work with. the Lambda function and the API gateway are implemented.

@David-Henandez-nrcan the page is existing, we just need to link a text box with the url call.

Several services and other elements have been created in the AWS console.

• User IAM to interact with the account

• Lambda function in python with.

  • URL_Object Class. as template for each source.
  • lambda_handler function.
    • Creates instances for both URLs sources with specific attributes and methods.
    • Reads parameters
    • Identifies and retrieves that parameter for address exists. otherwise defines failed query response
    • Identifies the occurrence of 'ids' parameters. The absence of this parameter leads to include them all
    • builds the query string for every service required based on attributes of each instance.
    • Executes the query call to get the response.
    • add the response to the body and return the response

• API Gateway associated with the Lambda.

  • Rest API option
  • Create method 'GET'
  • Integration type: Lambda function
  • Use Lambda proxy integration: Yes
  • Lambda Function: select the Lambda
  • Method Execution / get - URL Query String Parameters: add the parameters and select (if case) required for 'address'

url for POC: https://ngnxf545cb.execute-api.ca-central-1.amazonaws.com/dev usable parameters: address={address} ids=(geogratis,mapsgoogle)

Ex. https://ngnxf545cb.execute-api.ca-central-1.amazonaws.com/dev?address=meech&ids=geogratis

The Query and API are now placed in region central-1. Using 'mapsgoogle' id migth return error due to access rights

This issue can now be closed. all the bullets are checked. The most recent url to test its functionality is: https://ocni6zoj73.execute-api.ca-central-1.amazonaws.com/dev
