Initializing pipeline object with crawler in scrapy
问题 Based on Scrapy : Program organization when interacting with secondary website , I have: class MyPipeline(object): def __init__(self, crawler): self.crawler = crawler I'm trying to get a better understanding of the code especially the lines at the beginning listed above. Why would you initialize the pipeline object with a crawler. I have a lot of pipelines where I don't include this or any init method. What is the purpose of initializing the pipeline with a crawler? 来源: https://stackoverflow
