Web 抓取错误 - 站点所有者错误：站点密钥的域无效

Question

我试图获取此 URL 的内容 - https://www.zillow.com/homedetails/131-Avenida-Dr-Berkeley-CA-94708/24844204_zpid/ 我用的是刮擦的。这是我的代码。

import scrapy
class QuotesSpider(scrapy.Spider):
    name = "quotes"
    start_urls = [
        'https://www.zillow.com/homedetails/131-Avenida-Dr-Berkeley-CA-94708/24844204_zpid/',
    ]
    def parse(self, response):
        filename = 'test.html'
        with open(filename, 'wb') as f:
            f.write(response.body)
        self.log('Saved file %s' % filename)

我打开了抓取的数据(test.html)，我得到了这个内容。我试图找到解决方案并尝试了这个 - 但这并没有解决我的问题。

首先，试试这个方法，看看是否可行：

Headerz = {
    "accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9",
    "accept-encoding": "gzip, deflate, br",
    "accept-language": "en-US,en;q=0.9",
    "cache-control": "no-cache",
    "content-type": "application/x-www-form-urlencoded; charset=UTF-8",
    "pragma": "no-cache",
    "sec-fetch-mode": "navigate",
    "sec-fetch-site": "cross-site",
    "sec-fetch-user": "?1",
    "upgrade-insecure-requests": "1",
    "user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.130 Safari/537.36",
}

class QuotesSpider(scrapy.Spider):
    name = "quotes"
    start_urls = [
        'https://www.zillow.com/homedetails/131-Avenida-Dr-Berkeley-CA-94708/24844204_zpid/',
    ]

    def start_requests(self):
        yield scrapy.Request(start_urls[0], callback=self.parse, headers=Headerz)

    def parse(self, response):
        filename = 'test.html'
        with open(filename, 'wb') as f:
            f.write(response.body)
        self.log('Saved file %s' % filename)

我们之所以看不到在普通浏览器中看到的输出，是因为我们没有使用正确的 headers，否则总是由浏览器发送。

您需要按照上述代码添加 headers 或在 settings.py.

中更新它们

更好的方法是同时使用 'rotating-proxies' 个存储库和 'rotating-user-agent' 个存储库。
