代码

代码节点支持通过编写代码来生成返回值。支持在代码节点内使用 IDE 工具，编写自定义代码逻辑，来处理输入参数并返回响应结果。

当前仅支持 Python3。

代码

变量定义

声明代码中需要使用的变量。添加输入参数时需要设置参数名和变量值，其中变量值支持设置为固定值或引用上游节点的输出参数。

在代码中引用输入参数时，需要先在入参部分输入其变量名和类型，然后在函数内使用。

编写代码

          def main(var_1: str, var_2: str)->dict:
  {
    return: {
      "result": var_1 + var_2
    }
  }

        

代码节点中需要执行的代码片段。

• 引用变量：直接使用输入参数中的变量，通过返回一个对象来输出处理结果。

• 函数限制：不支持编写多个函数。即使仅有一个输出值，也务必保持以对象的形式返回。

输出

代码运行成功后，输出的参数。你可以根据实际需求，在输出结构中只保留必要的参数。

注意：需要确保此处定义的参数名、类型与代码的 return 对象完全一致。以代码节点默认提供的代码为例，输出的参数与代码中定义的 return 对象完全一致。
