Tripadvisor 的 Scrapy Spider 抓取了 0 页(以 0 页/分钟的速度) [英] Scrapy spider for Tripadvisor Crawled 0 pages (at 0 pages/min)

问题描述

我正在尝试收集蓬塔卡纳所有酒店的评论.代码似乎可以运行，但是当我调用 crawl 时，它实际上并没有爬取任何站点.这是我的文件结构、我调用的内容以及运行时发生的情况.

文件夹结构:

items.py

导入scrapy类 TripadvisorReviewsItem(scrapy.Item):# 在此处为您的项目定义字段，例如:标题 = scrapy.Field()内容=scrapy.Field()# 星星 = scrapy.Field()

我在终端中使用以下命令运行它:

scrapy 爬取tripadvisorspider -o items.json

这是我的终端输出

解决方案

此选择器不起作用:

response.xpath('//div[@class="hotels-review-list-parts-ReviewTitle__reviewTitleText"]/a/@href')

网站上的元素是 而不是

，而且类名似乎是错误的.也许这个站点在类名后附加了一些随机数据，如下所示

<a href="/ShowUserReviews-g3176298-d259337-r673990694-Grand_Palladium_Bavaro_Suites_Resort_Spa-Bavaro_Punta_Cana_La_Altagracia_Provinc.html" class="hotels">Tirespanr3" class="hotels">Tirespanr3;span>Ótima体验！Resort amplo, com diversas opções de entretenimento!!!</span></span></a>

您可以尝试只匹配字符串的一部分，例如:

//a[contains(@class, "hotels-review-list-parts-ReviewTitle__reviewTitleText")]

I'm trying to scrape reviews for all hotels in Punta Cana. The code seems to run but when I call crawl, it doesn't actually crawl any of the sites. Here are my file structures, what I called, and what happened when I ran it.

        print(item)
        yield item

items.py

import scrapy


class TripadvisorReviewsItem(scrapy.Item):
    # define the fields for your item here like:
    title = scrapy.Field()
    content = scrapy.Field()
    # stars = scrapy.Field()

I ran it using the following command in terminal:

scrapy crawl tripadvisorspider -o items.json

This is my terminal output

解决方案

This selector is not working:

response.xpath('//div[@class="hotels-review-list-parts-ReviewTitle__reviewTitleText"]/a/@href')

The element on the site is <a> and not <div>, also the class name seems wrong. Perhaps this site append some random data to the class name, as you can see below

<a href="/ShowUserReviews-g3176298-d259337-r673990694-Grand_Palladium_Bavaro_Suites_Resort_Spa-Bavaro_Punta_Cana_La_Altagracia_Provinc.html" class="hotels-review-list-parts-ReviewTitle__reviewTitleText--3QrTy"><span><span>Ótima experiência! Resort amplo, com diversas opções de entretenimento!!!</span></span></a>

You can try to match only part of the string, for example:

//a[contains(@class, "hotels-review-list-parts-ReviewTitle__reviewTitleText")]
