Question

我正在测试Scrapy来抓取网页。我无法抓取我想要的页面，我找不到原因。谁能解决我的问题？

P.S。对于某人的提醒，上一个网页显示错误。我改变了路径。

total_corner_spider.py

name = "totalcorner"
allowed_domains = ["totalcorner.com"]
start_urls = [
    "http://www.totalcorner.com/match/corner_stats/57868009",
]

def parse(self, response):
    histories = Selector(response).xpath('//*[@id="home_history_table"]/tbody')
    for history in histories:
        item = HistoryItem()
        item['leagueId'] = history.xpath(
            'a[@data-league_id').extract()[0]
        yield item

items.py

from scrapy.item import Item, Field


class HistoryItem(Item):
    leagueId = Field()

之后

>>> scrapy crawl totalcorner -o some.json,

我发现.json文件只包含“[”

之后

>>> scrapy crawl totalcorner

我从终端获得以下日志：

Answer 1

我找到了原因，这是一个愚蠢的错误。蜘蛛的文件名应为totalcorner_spider.py。我的错。谢谢你的努力。
