PinsterApi

The api that brings the bacon home.

Flows

New pin

1. In auth0 admin control panel make sure user has create:pin permission
2. Get an access token from auth0. We'll call it our auth0_token
3. POST to /v1/pins using your auth0_token as a Bearer token with a body like so:

   {
     "data": {
       "name": "Wisconsin Unicorn",
       "year": 2009,
       "description": "This unicorn was made up, unless it exists. It is a very cool unicorn."
     }
   }

   Your response will look like:

   {
     "id": "3d3987fa-4fb6-4b2d-8980-c1919f5e63ec",
     "name": "Wisconsin Unicorn",
     "year": 2009,
     "description": "This unicorn was made up, unless it exists. It is a very cool unicorn.",
     "tags": [],
     "created_at": "2019-05-15T22:59:01.754Z",
     "updated_at": "2019-05-15T22:59:01.754Z",
     "images_url": "http://www.example.com/v1/pins/3d3987fa-4fb6-4b2d-8980-c1919f5e63ec/images",
     "url": "http://www.example.com/v1/pins/3d3987fa-4fb6-4b2d-8980-c1919f5e63ec"
   }

4. You're done! You've created a Pin! This is the same flow for any other item in the api.

Add image to existing imageable

Almost everything in PinsterApi is imageable so this process can be applied to Users, Pins, Assortments, and Collections, etc.

1. Do a GET (POST will have the same data if you're creating a resource) on the resource you'd like to add an image to. The images_url will be in the response body: Example response for a Pin:

   {
     "id": "3d3987fa-4fb6-4b2d-8980-c1919f5e63ec",
     "name": "Wisconsin Unicorn",
     "year": 2009,
     "description": "This unicorn was made up, unless it exists. It is a very cool unicorn.",
     "tags": [],
     "created_at": "2019-05-15T22:59:01.754Z",
     "updated_at": "2019-05-15T22:59:01.754Z",
     "images_url": "http://www.example.com/v1/pins/3d3987fa-4fb6-4b2d-8980-c1919f5e63ec/images",
     "url": "http://www.example.com/v1/pins/3d3987fa-4fb6-4b2d-8980-c1919f5e63ec"
   }

   1. Note, the images_url isn't special, it's just in the response for your convenience. All imageables have a /images route on which you can do GET and POST.

2. Parse response for the images_url

3. POST to images_url without a body using your auth0_token as a Bearer token. Your response will look like this:

   {
     "image_service_token": "eyJhbGciOiJSUzI...",
     "image_service_url": "http://images.example.com"
   }

   1. Note: These tokens are specific to the imageable and will expire shortly after they are generated (10 minutes or so). All images uploaded to image service with this token will be attached to the imageable for which this token was generated.

4. Parse response for the image_service_token and image_service_url

5. POST to image_service_url using the image_service_token as a Bearer token with a body like so:

   {
     "data": {
       "image": "base64 encoded image",
       "name": "Optional name of image",
       "description": "Optional description",
       "featured": "Optional ISO8601 format"
     }
   }

   Your response will look like this but you don't have to parse this:

   {
     "bucket": "image-service-upload-dev.pinster.io",
     "key": "raw/d01834089090031b1c7d098882cfb41b",
     "message": {
       "ETag": "\"d01834089090031b1c7d098882cfb41b\""
     }
   }

6. Image service will process your image and if it passes moderation it will POST back to the api on your behalf, linking the image to your imageable (pin in this case)!

Deployment

Checklist

1. Generate new OpenSSL::PKey::RSA.generate(2048) keys for image service and pinster api. Use rails generate_keys and the keys.env file will contain urlsafe base64 encoded keys for use in environment variables.

2. Set environment variables in elasticbeanstalk configure thing.

3. Set environment variables in secrets manager for image service's keys

4. run on ec2 instance

   PgSearch::Multisearch.rebuild(Pin, true)
   PgSearch::Multisearch.rebuild(Assortment, true)

5. Set these envs:

   SWAGGER_HOST=
   RDS_DB_NAME=
   RDS_HOSTNAME=
   RDS_PASSWORD=
   RDS_PORT=
   RDS_USERNAME=
   SECRET_KEY_BASE=
   AUTH0_SITE=
   JWT_AUD=
   IMAGE_SERVICE_URL=
   PRIVATE_KEY=
   IMAGE_SERVICE_PUBLIC_KEY=

6. Set up auth0
