Running it on IronFunctions

Let's define some environment variables

# Set your Function server address
# Eg. 127.0.0.1:8080
FUNCAPI=YOUR_FUNCTIONS_ADDRESS

CUSTOMER_KEY="XXXXXX"
CUSTOMER_SECRET="XXXXXX"
ACCESS_TOKEN="XXXXXX"

Running with IronFunctions

With this command we are going to create an application with name twitter.

curl -X POST --data '{
    "app": {
        "name": "twitter",
        "config": { 
            "CUSTOMER_KEY": "'$CUSTOMER_KEY'",
            "CUSTOMER_SECRET": "'$CUSTOMER_SECRET'", 
            "ACCESS_TOKEN": "'$ACCESS_TOKEN'",
            "ACCESS_SECRET": "'$ACCESS_SECRET'"
        }
    }
}' http://$FUNCAPI/v1/apps

Now, we can create our route

curl -X POST --data '{
    "route": {
        "image": "'$USERNAME'/func-twitter",
        "path": "/tweets",
    }
}' http://$FUNCAPI/v1/apps/twitter/routes

Testing function

Now that we created our IronFunction route, let's test our new route

curl -X POST --data '{"username": "getiron"}' http://$FUNCAPI/r/twitter/tweets
