README

Extension to easily configure an OAuth client for OAT platform.

Setting up OAuth

1. At host server run console script to generate credentials: php index.php '\oat\taoOauth\scripts\tools\GenerateCredentials' -r $role . (final bash inliner may vary according to your server); It will return $key, $secret and $tokenUrl, which should be used to generate auth token. This data should be stored in your client env.

Response:

Client generated with credentials :
 - client key  : c35b263b78fa20aa560702a232fff5fc
 - client secret  : GSJ2z6xH3E3MelJbXA6AmQeQeYfCRueg3af9a92aba6bfc28559a8c5689adbc87fd901f18b00671e3bc5d5566f5af5e38
 - token url  : https://taotesting.com/taoOauth/TokenApi/requestToken

1. If your client server works with Tao, you can run script which will import credentials to allow authentication against host server: php index.php '\oat\taoOauth\scripts\tools\ImportConsumer' -k $key -s $secret -tu $tokenUrl -r $role.

Using OAuth authentication

After generate of credentials you need to generate token for connections to the tao endpoints. For this you need to make request:

curl -X POST \
  https://taotesting.com/taoOauth/TokenApi/requestToken \
  -H 'Accept: application/json' \
  -H 'Cache-Control: no-cache' \
  -H 'Content-Type: application/json' \
  -d 'client_id=c35b263b78fa20aa560702a232fff5fc&client_secret=GSJ2z6xH3E3MelJbXA6AmQeQeYfCRueg3af9a92aba6bfc28559a8c5689adbc87fd901f18b00671e3bc5d5566f5af5e38'

where $key and $secret your credentials from previous example.

It will return $access_token and $expires, which should be used to generate Authorization header:

  {
      "access_token": "hJFpTCo9Bvd30b7eb63ef28af1a7ce081252e9844053a9a4a38112ecb8c41eeedfd58f8907",
      "expires": 1521475157
  }

Request with OAuth Authorization header

Example:

   curl -X GET \
        'https://taotesting.com/taoDeliveryRdf/RestDelivery/getStatus?id=https%3A%2F%2Ftaotesting.com%2Ftao.rdf%23i15203488932024127 \
        -H 'Accept: application/json' \
        -H 'Authorization: Bearer hJFpTCo9Bvd30b7eb63ef28af1a7ce081252e9844053a9a4a38112ecb8c41eeedfd58f8907' \
        -H 'Cache-Control: no-cache' \
        -H 'Content-Type: application/json' \
