I am trying to collect the data number of people helps in SOPT, ie my impact, to put in an api later, but is not extracting the information.

Spider:

import scrapy

class StackOverflow(scrapy.Spider):
    name = 'stackoverflow'
    start_urls = ['/users/17340/david']

    def parse(self, response):
        impact = response.xpath('//*[@id="top-cards"]/aside[3]/div/div[1]/div[1]/text()').extract()

        yield impact

I’m running with command:

scrapy crawl stackoverflow

My folder structure:

├── scrapy.cfg
└── stackoverflow
    ├── __init__.py
    ├── items.py
    ├── middlewares.py
    ├── pipelines.py
    ├── settings.py
    └── spiders
        ├── __init__.py
        └── stackoverflow.py

Does anyone have any idea why you’re not bringing the information?


Observing: If capturing this SOPT information is against the rules, please delete this post.

  • ERROR: Spider must return Request, BaseItem, dict or None, got 'list'. Probably the selector you made is returning a list, if you debug this code, what is the value of impact?

  • empty, but the return would be one item only, at least by the reset xpath only 1 term.
