What is it ?

This package allows you to create an API that will serve a single endpoint.

The goal is to be able to send data to this endpoint, to process it in a series of steps.

Installation

composer require php-etl/workflow

Basic usage

Your HTTP Hook will serve the route set in the option path:

version: '0.3'
satellites:
  my_satellite:
    label: 'Example of a hook'
    filesystem:
      path: build
    composer:
      require:
        - "middlewares/uuid:dev-master"
        - "middlewares/base-path:dev-master"
        - "middlewares/request-handler:dev-master"
        - "middlewares/fast-route:dev-master"
        - "laminas/laminas-diactoros"
        - "laminas/laminas-httphandlerrunner"
        - "nyholm/psr7-server"
        - "nyholm/psr7"
        - "php-etl/pipeline"
        - "php-etl/satellite"
        - "php-etl/api-runtime"
        - "php-etl/mapping-contracts"
    http_hook:
      name: 'My HTTP Hook' # Optional
      path: /my-hook
      expression: 'input'
      pipeline:
        steps:
          - fastmap:
              map:
                - field: '[sku]'
                  copy: '[product_name]'
                - field: '[id]'
                  copy: '[product_code]'
          - csv:
              loader:
                file_path: 'output.csv'

After building the satellite, start a server in the path build/:

bin/satellite run:hook build/

You can then send POST requests containing the data be processed to http://localhost:8000/my-hook

# input:
[
  { product_name: 'test_1', product_code: 861 },
  { product_name: 'test_2', product_code: 862 }
]

# response:
{"message":{"accept":4,"reject":0,"error":0},"server":"my-computer.local"}
  
# output.csv:
sku;id
test_1;861
test_2;862

Advanced usage

Adding JSON Web Token (JWT) Authorization

# ...
    composer:
      require:
        - "tuupola/slim-jwt-auth"
# ...
    http_hook:
      authorization:
        jwt:
          secret: 'mysecret'

With this config, each requests will need the header Authorization:

header	value
`Authorization`	`Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6Ik`[…]

The string after “Bearer” is the token, generated from the secret phrase. This site can be used to generate a token from your own secret: https://jwt.io

Adding Basic HTTP Authorization

# ...
    composer:
      require:
        - "tuupola/slim-basic-auth"
# ...
    http_hook:
      authorization:
        basic:
          - user: john
            password: mypassword
          - user: bill
            password: otherpassword

The basic node is an array, and can contain multiple user/password pairs.

With this configuration, each requests will need the header Authorization:

header	value
`Authorization`	`Basic am9objpteXBhc3N3b3Jk`

The string after “Basic” is the combination user:password encoded in Base64.
