Via API Manager

Step 1 - Configure Choreo Connect with API Manager

  • To start Choreo Connect with an existing API Manager instance, follow the steps here
  • To start a complete deployment setup that includes an API Manager instance and a Choreo Connect instance already configured to work with API Manager, follow the steps here

Step 2 - Create an API in API Manager

Follow the steps here.

Step 3 - Deploy the API in API Manager

The guide here will explain how you could easily deploy the API you just created.

That's it! To invoke the API follow the steps here.

During the startup, Choreo Connect will check the config.toml to see if the controlPlane.eventHub configuration has been enabled. If so, it will start fetching all the necessary artifacts that belongs to the gateway environment given in environmentLabels. These artifacts include deployed APIs, Applications, Subscriptions, Polices, information related to Key Managers, etc.

Whenever a new event occurs in API Manager such as an API being deployed, API Manager will notify Choreo Connect via Event Hub. Choreo Connect will then start fetching all the new artifacts related to its environment.

Tip

To be able to invoke an API via the Developer Portal TryOut Console, make sure at least one of the certificates used by the enforcer is same as the certificate used by the Key Manager configured in API-M. In Choreo Connect, the certs for enforcer are located at <CHOREO-CONNECT_HOME>/docker-compose/resources/enforcer/security/truststore. In API-M, Key Managers can be configured from the API-M Admin Portal.

Step 4 - Invoke the API

After the APIs are exposed via Choreo Connect, you can invoke an API with a valid token (JWT or opaque access token).

Let's use the following command to generate a JWT to access the API, and set it to the variable TOKEN.

TOKEN=$(curl -X POST "https://localhost:9095/testkey" -H "Authorization: Basic YWRtaW46YWRtaW4=" -k -v)
Execute the following cURL command to Invoke the API using the JWT.

curl -X GET "https://<CHOREO-CONNECT_ROUTER_HOST>:<CHOREO-CONNECT_ROUTER_PORT>/<API-context>/<API-resource>" -H "accept:application/xml" -H "Authorization:Bearer $TOKEN" -k
curl -X GET "https://localhost:9095/v2/pet/findByStatus?status=available" -H "accept: application/xml" -H "Authorization:Bearer $TOKEN" -k

Refer to Generate a Test JWT for more details.
