Do You Have Sample Code for Initializers?

Yes. See the following examples:

• Node.js (Initializer introduction)

  exports.initializer = function(context, callback) {
      callback(null, '');
      };

• Python (Initializer introduction)

  def my_initializer(context):
      print("hello world!")

• Java (Initializer introduction)

  public void my_initializer(Context context)
  {
  RuntimeLogger log = context.getLogger();
  log.log(String.format("ak:%s", context.getAccessKey()));
  }

• PHP (Initializer introduction)

  <?php
  Function my_initializer($context) {
      echo 'hello world' . PHP_EOL;
      }
  ?>
