1、 以如下为例

>>> 配置文件
version: "3.1"

flows:
  switch_user_id:
    name: 切换账号
    description: 切换账号、切换用户、更换用户ID
    persisted_slots:
      - user_id
    steps:
      - collect: user_id
        description: 用户id
        ask_before_filling: true
        next: END

>>> safe_load后：
data = {
    "version": "3.1",
    "flows": {
        "switch_user_id": {
            "name": "切换账号",
            "description": "切换账号、切换用户、更换用户ID",
            "persisted_slots": ["user_id"],
            "steps": [
                {
                    "collect": "user_id",
                    "description": "用户id",
                    "ask_before_filling": True,
                    "next": "END",
                }
            ],
        },
        ...
    },
}

>>> 所以steps_data
steps_data = flow_config.get("steps", [])
# steps_data == [
#   {
#     "collect": "user_id",
#     "description": "用户id",
#     "ask_before_filling": True,
#     "next": "END",
#   }
# ]


2、带条件列表 + 嵌套动作
- collect: order_id  # button展示给用户，用户选择一个订单
  next:
    - if: slots.order_id != "false"
      then:
        - action: action_get_order_detail
          next: END
    - else: END


step_data = {
    "collect": "order_id",
    "next": [
        {
            "if": "slots.order_id != \"false\"",
            "then": [
                {
                    "action": "action_get_order_detail",
                    "next": "END",
                }
            ],
        },
        {
            "else": "END",
        },
    ],
}
