刮擦自定义设置

scrapy python

Jan · 技术社区 · 6 年前

scrapy ,我的一个蜘蛛里有:

class IndexSpider(scrapy.Spider):
    name = "indices"

    def __init__(self, *args, **kwargs):
        super(IndexSpider, self).__init__(*args, **kwargs)

        # set custom settings
        custom_settings = {
            'DOWNLOAD_DELAY': 2,
            'ITEM_PIPELINES': {
                'freedom.pipelines.IndexPipeline': 300
            }
        }

但是,当我稍后尝试通过

    print(dict(self.settings.get('ITEM_PIPELINES')))

我做错什么了?

custom_settings 应该是类属性:

class IndexSpider(scrapy.Spider):
    name = "indices"

    # set custom settings
    custom_settings = {
        'DOWNLOAD_DELAY': 2,
        'ITEM_PIPELINES': {
            'freedom.pipelines.IndexPipeline': 300
        }
    }

    def __init__(self, *args, **kwargs):
        super(IndexSpider, self).__init__(*args, **kwargs)
