Python 2.7 Scrapy shell可以工作，但实际脚本返回404错误

返回正确的200代码

scrapy shell http://www.zara.com/us

在终端中键入：

scrapy crawl zara us

class ZaraSpider(scrapy.Spider):

    name = "zara-us"
    allowed_domain = ['www.zara.com/us']
    start_urls = [
        "http://www.zara.com/us"
    ]
    handle_httpstatus_list = [404]

    # navigating main page
    def parse(self, response):

        # get 1st 2 category listing in navigation sidebar
        categories = response.xpath('//*[@id="menu"]/ul/li')
        collections = categories[0].xpath('a//text()').extract()
        yield ProductItem(collection=collections[0])

默认情况下，Scrapy for every new projects将启用
ROBOTS\u TXT\u obe
为True，这意味着在您的爬行器可以刮取任何内容之前，它会检查网站
ROBOTS.TXT
文件中允许刮取和不允许刮取的内容

要禁用此功能，只需从
settings.py
文件中删除设置
ROBOTS\u TXT\u obe
