Question

在使用scrapy抓取家庭网站时，它经常引发 AttributeError ****响应内容不是文字。我不知道如何解决它。

import scrapy
from scrapy.http import Request
from ershoufang.items import ErshoufangItem
from scrapy.http import HtmlResponse

from scrapy.selector import Selector

class HouseSpider(scrapy.Spider):
    name = 'house'
    allowed_domains = ['qhd.58.com', 'short.58.com', 'jxjump.58.com']
    header = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.221 Safari/537.36 SE 2.X MetaSr 1.0'
    }

    def start_requests(self):
        pages = []

        for i in range(1,11):
            url = 'http://qhd.58.com/ershoufang/pn'+str(i)
            page = scrapy.Request(url,headers=self.header)
            pages.append(page)
        return pages

    def parse(self, response):
        urls = response.xpath('//div[@class="list-info"]/h2[@class="title"]/a/@href').extract()
        for url in urls:
            yield scrapy.Request(url,headers=self.header,callback=self.parse_page)

    def parse_page(self,response):
        url = [response.url]
        sel = Selector(response)

        title = sel.xpath('//div[@class="house-title"]/h1[1]/text()').extract()
        updatetime = sel.xpath('//p[@class="house-update-info"]/span[@class="up"][1]/text()').extract()
        totalcount = sel.xpath('//p[@class="house-update-info"]/span[@class="up"][2]/em[@id="totalcount"]/text()').extract()
        totalprice = sel.xpath('//div[@class="general-item general-situation"]/div[@class="general-item-wrap"][1]/ul[@class="general-item-left"]/li[1]/span[2]/text()').extract()
        area = sel.xpath('//div[@class="general-item general-situation"]/div[@class="general-item-wrap"][1]/ul[@class="general-item-left"]/li[3]/span[2]/text()').extract()
        orientation = sel.xpath('//div[@class="general-item general-situation"]/div[@class="general-item-wrap"][1]/ul[@class="general-item-left"]/li[4]/span[2]/text()').extract()
    ...

然后我设置 DOWNLOAD_DELAY ，但它不起作用。以下是错误的屏幕截图： enter image description here

这是我的蜘蛛日志文件的一部分：

Answer 1

如果您正在处理压缩响应，有时检查 request.body 可能会有所帮助：

import zlib

zlib.decompress(request.body, 15+32)

为什么scrapy提高回复内容不是文本
