为什么Scrapy不适用于此页面？

Question

我正在尝试抓取此网页：

http://www.oddsportal.com/search/results/:69Dxbc61/

这是我的代码：

import scrapy

class Test2Spider(scrapy.Spider):
    name = "test2"
    allowed_domains = ["oddportal.com"]
    start_urls = (
        'http://www.oddsportal.com/search/results/:69Dxbc61/',
    )

    def parse(self, response):
        for partita in response.css('tr.deactivate'):
            yield {
                'score': partita.css('td.table-score::text').extract_first(),
            }

但是我得到这个：

为什么？

Answer 1

似乎网站被刮擦打开时出现404错误，而在浏览器中查看时却正常工作。

这种行为通常意味着您请求的标头存在问题。

在这种情况下，似乎只需设置其他用户代理即可解决该问题。
