CircleCI

fb-user-filestore

A Ruby on Rails application to handle file uploads from forms on the Form Builder platform

Running tests

Prerequisites:

  • Docker
make spec

Deployment

Continuous Integration (CI) is enabled on this project via CircleCI.

On merge to main tests are executed and if green deployed to the test environment. This build can then be promoted to production

Making API calls

To craft calls to the API the below script can be used from the rails console. This will hit the API with a valid request to upload a file and then download the same file.

require Rails.root.join('spec/support/request_helpers.rb')

payload = json_request(Base64.strict_encode64(File.open(Rails.root.join('spec/fixtures/files/image.png')).read));
jwt_payload = { iat: Time.now.to_i, checksum: Digest::SHA256.hexdigest(payload.to_json) }
`curl -X POST --header "x-access-token: #{JWT.encode(jwt_payload, 'service-token', 'HS256')}" --header "Content-Type: application/JSON" --data '#{payload.to_json}' http://localhost:3000/service/some-service/user/some-user`

# response => "{\"url\":\"/service/some-service/user/some-user/28d-e71c352d0852ab802592a02168877dc255d9c839a7537d91efed04a5865549c1\",\"size\":173,\"type\":\"image/png\",\"date\":1554734786}"

payload = { encrypted_user_id_and_token: '12345678901234567890123456789012', iat: Time.now.to_i }
jwt_payload = { iat: Time.now.to_i, checksum: Digest::SHA256.hexdigest(payload.to_json) }
query_string_payload = Base64.strict_encode64(payload.to_json)
response = `curl -X GET --header "x-access-token: #{JWT.encode(jwt_payload, 'service-token', 'HS256')}" http://localhost:3000/service/some-service/user/some-user/28d-e71c352d0852ab802592a02168877dc255d9c839a7537d91efed04a5865549c1?payload=#{query_string_payload}`

hash = JSON.parse(response)

File.open('/tmp/out', 'wb') {|f| f.write Base64.strict_decode64(hash['file']) }
