Use environment variables

You can use code to read system environment variables and configure the environment variables to the runtime environment of a function to run the function. This topic describes the sample code for using environment variables in different runtime environments.

var value = process.env.key
console.log(value)

import os
value = os.environ.get('key')
print(value)

System.out.println("value: "+ System.getenv("key"));

$value = getenv('key');

Console.WriteLine(Environment.GetEnvironmentVariable("key"));
