看得不是很明白 ，那两个参数是怎么传过来的？能解释一下吗？

框架传过来的，你需要做的是

1. setting里配置

   # 数据入库的pipeline，支持多个
   ITEM_PIPELINES = [
   "pipeline.Pipeline" # pipeline文件名.类名
   ]

2. 实现pipeline

   
   from feapder.pipelines import BasePipeline
   from typing import Dict, List, Tuple

class Pipeline(BasePipeline): """ pipeline 是单线程的，批量保存数据的操作，不建议在这里写网络请求代码，如下载图片等 """

def save_items(self, table, items: List[Dict]) -> bool:
    """
    保存数据
    Args:
        table: 表名
        items: 数据，[{},{},...]

    Returns: 是否保存成功 True / False
             若False，不会将本批数据入到去重库，以便再次入库

    """

    这里保存文件

    return True

研究出来了，谢谢。这个框架比那个scrapy好用多了。文档也写得很清晰，易学，容易上手。
