我正在遵循scrapy教程here，我正试图将它与我自己的项目链接起来。
我首先通过运行以下命令创建一个项目：

scrapy startproject idealistaScraper

接下来，我转到spiders文件夹，并使用以下代码创建一个新的python文件：

import scrapy

print("\n", "-"*145, "\n", "-"*60, "Starting the Scrapy bot", "-"*60, "\n", "-"*145, "\n")
class QuotesSpider(scrapy.Spider):
    name = "idealistaCollector"

    def start_requests(self):
        urls = [
            'https://www.idealista.com/inmueble/97010777/'
            #'https://www.idealista.com/inmueble/97010777/',
        ]
        for url in urls:
            yield scrapy.Request(url=url, callback=self.parse)

    def parse(self, response):
        page = response.url.split("/")[-2]
        filename = f'quotes-{page}.html'
        with open(filename, 'wb') as f:
            f.write(response.body)
        self.log(f'Saved file {filename}')

另存为：connection_spider.py .
最后，我运行以下代码

scrapy crawl idealistaCollector

其中，idealistaCollector是我在connection_spider.py文件中为刮刀指定的name。
我得到的输出如下：

因此，我的问题是，我如何导航我得到的403错误？

2022-04-08 18:42:52 [scrapy.core.engine] DEBUG: Crawled (403) <GET https://www.idealista.com/robots.txt> (referer: None)

我也尝试过将以下自定义头文件添加到connection_spider.py文件中，但仍然没有任何运气。

我还得到了403使用scrapy的情况下，两个网址：这里和here，但当我使用python requests模块，然后它的工作意味着响应状态：200
下面是一个例子，你可以检验一下：

from bs4 import BeautifulSoup
import requests

url = 'https://www.idealista.com/venta-viviendas/barcelona/sant-marti/el-parc-i-la-llacuna-del-poblenou/pagina-3.htm'

# url='https://www.idealista.com/inmueble/97010777/'

r = requests.get(url)

# print(r)

soup = BeautifulSoup(r.text, 'html.parser')
for url in soup.select('.item-info-container >a'):
    abs_url='https://www.idealista.com'+ url.get('href')
    print(abs_url)

输出量：
