Python 多个方法之间无法正确传递刮擦元或cb_kwargs

我正在浏览一个健身网站

我有不同的方法，比如，抓取主页、分类和产品信息，我试图使用meta/cb_-kwargs在字典中传递所有这些级别的信息

代码：

问题:

我有两个变量要监控，调用了多少次

parse_by_category

和

get_product_info

，启动的计数器变量分别是

category_counter

和

product_counter

我正在为每个产品（总共132个产品）调用

get\u product\u info

方法，

self.product\u计数器

应该是132，但它只产生了3次

我还使用了scrapy信号来检查计数器及其输出

SPIDER CLOSED
Category Counter length
132
product counter length
3

self.category_计数器工作正常-132次

但是self.product_计数器-仅3次

执行日志

不确定我遗漏了什么，请帮忙。

你能分享执行日志吗？我假设所产生的项目也只有3？更新了日志，请check@renatodvc还需要别的吗？你可能想试试
