Question

我已开始在Ubuntu 11上使用scrapy，并面临问题。具体来说，以下代码中的解析函数不会执行，尽管终端显示已成功执行和关闭的蜘蛛

from scrapy.contrib.spiders import CrawlSpider
from scrapy.selector import HtmlXPathSelector



class myTestSpider(CrawlSpider):
    name="go4mumbai.com"
    domain_name = "go4mumbai.com"
    start_urls = ["http://www.go4mumbai.com/Mumbai_Bus_Route.php?busno=1"]

def parse(self, response):  
    hxs = HtmlXPathSelector(response)
    stopNames=hxs.select('//table[@cellspacing="2"]/tr/td[2]/a/text()').extract()
    print len(stopNames)

SPIDER = myTestSpider()

以下是终端的回复

我遗漏了部分代码吗？请指教..

Answer 1

您的parse()函数似乎不属于您的蜘蛛类。缩进一个缩进的整个函数，因此它属于类并被调用。

Scrapy“解析”功能未被执行
