# Uses the DELETE method to delete a Firebase record.

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# This example assumes a JWT authentication token, if required, has been previously obtained.
# See Get Firebase Access Token from JSON Service Account Private Key for sample code.

# Load the previously obtained Firebase access token into a string.

accessToken = fac.readEntireTextFile("qa_data/tokens/firebaseToken.txt","utf-8")
if (fac.get_LastMethodSuccess() != true)
    print fac.lastErrorText() + "\n";
    exit
end

rest = Chilkat::CkRest.new()

# Make the initial connection (without sending a request yet).
# Once connected, any number of requests may be sent.  It is not necessary to explicitly
# call Connect before each request.  
success = rest.Connect("chilkat.firebaseio.com",443,true,true)

    print rest.lastErrorText() + "\n";

rest.SetAuthGoogle(authGoogle)

# Chilkat's sample data (pig-rescue data) is publicly readable at: https://chilkat.firebaseio.com/.json
# This data is publicly readable, but not writable.  You'll need to 
# run against your own database..

# We're going to delete a pig we previously added.  The push ID of that pig was -KI3pT33wKauiMxY4QTB,
# so the path will be "/pig-rescue/animal/-KI3pT33wKauiMxY4QTB.json"

    # and then receive the response in another call.)

# Check the response status code.   A 200 response status indicates success.
