(Perl) Firebase PUT - Writing Data

Demonstrates how to PUT new data to a Firebase JSON database. The data used in this example is at Chilkat Firebase Pigs Database, and is shown here:

# Demonstrates how to PUT new data to a Firebase JSON database.

# 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.

# 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.

# 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..

# Generate a new push ID.

# We're going to add a new pig with just the name.

if ($rest->get_LastMethodSuccess() != 1) {
    # Something happened in the communications (either no request was sent, or no response was received.
    # (The Chilkat REST API also has lower-level methods where an app can send the request in one call,
    # and then receive the response in another call.)
    print $rest->lastErrorText() . "\r\n";
    exit;
}

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

# Note: In many of the Chilkat examples, you may notice strange ways
# of doing something that should be simpler and shorter.  For example,
# building the path (above) could've been written differently,
# with some simple string concatenation.
# 
# The reason is that the Chilkat examples are written in a 
# proprietary "example code" scripting language,
# and then automatically generated to each of the different programming
# languages you see on example-code.com.  The code generation is
# limited in what it can do.  For example, string concatentation
# is not yet a feature of the "example code" scripting language (as of May 2016), 
# and therefore you won't see the use of a programming language's string
# concatentation operators in any example.
