结构节点基础文件(Structure of the node base file)#

节点基础文件遵循以下基本结构：

🌐 The node base file follows this basic structure:

  1. 添加导入语句
  2. 创建节点类
  3. 在节点类中，创建一个 description 对象，它定义了该节点。

编程式节点也有一个 execute() 方法，它用来读取传入的数据和参数，然后构建请求。声明式风格通过在 descriptions 中的 properties 对象中使用 routing 键来处理这一点。

🌐 A programmatic-style node also has an execute() method, which reads incoming data and parameters, then builds a request. The declarative style handles this using the routing key in the properties object, within descriptions.
