定义节点

# node1.py

class HelloNode(MossNode):
  
  _should_shutup = False

  def on_running(self):
    print('Hello Node is running')
  
    while not self._should_shutup:
      time.sleep(5)
      self.pub_to_service('<Other Node Service Id>', 'Hi!')

    
  def on_messaged(self, route, body):
    data = str (body, 'utf-8')
    print(f'[Rx] {route}, {data}')
    if route == 'urn:node:id:5cf3ed19-571d-4631-9bb0-e62de70bedea:service:shutup':
      self._should_shutup = True

配置节点

  "nodes": [
    {
      "id": "urn:node:id:5cf3ed19-571d-4631-9bb0-e62de70bedea",

      "config": {}
    }
  ]
}

调起 TinyMoss

from tinymoss import TinyMoss

moss = TinyMoss()
try:
    moss.startup()
    while True:
        time.sleep(.1)
except KeyboardInterrupt:
    moss.shutdown()
