Как отправлять get-запрос на получение json файла через фреймворк scrapy?

Автор вопроса: Dima2203L

Пытаюсь написать парсер изображений с pinterest используя фреймворк scrapy, сайт подтягивает изображения динамически, методом тыка был найдет json файл в котором хранятся ссылки на изображения, проблема состоит в том что при отправке get запроса через паука, возвращается пустой список. Что я делаю не так, и как правильно нужно отправлять get запрос на получения json файла?

import scrapy
import json


class PintercopySpider(scrapy.Spider):
   name = "pintercopy"
   # allowed_domains = ["s"]
   start_urls = ["https://ru.pinterest.com/search/pins/? 
   rs=ac&len=2&q=forest&eq=for&etslf=7427"]

headers = {
    "Accept" : "application/json, text/javascript, */*, q=0.01",
    "Accept-Encoding" : "gzip, deflate, br",
    "Accept-Language" : "ru,en;q=0.9",
    "Referer" : "https://ru.pinterest.com/",
    "Sec-Fetch-Mode" : "cors",
    "Sec-Fetch-Site" : "same-origin",
    "User-Agent" : "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36",
    "X-Requested-With" : "XMLHttpRequest",
}

def parse(self, response):
    url = 'https://ru.pinterest.com/resource/BaseSearchResource/get/?source_url=%2Fsearch%2Fpins%2F%3Frs%3Dac%26len%3D2%26q%3Dforest%26eq%3Dfor%26etslf%3D7427&data=%7B%22options%22%3A%7B%22article%22%3A%22%22%2C%22appliedProductFilters%22%3A%22---%22%2C%22price_max%22%3Anull%2C%22price_min%22%3Anull%2C%22query%22%3A%22forest%22%2C%22scope%22%3A%22pins%22%2C%22auto_correction_disabled%22%3A%22%22%2C%22top_pin_id%22%3A%22%22%2C%22filters%22%3A%22%22%2C%22page_size%22%3A%2225%22%7D%2C%22context%22%3A%7B%7D%7D&_=1706559284548'

    yield scrapy.Request(url, method='GET' , headers=self.headers)

'2.6' is a deprecated value for the

It is also the default value. In other words, it is normal to get 
this warning if you have not defined a value for the

backward compatibility reasons, but it will change in a future 
version of Scrapy.

Данные хранятся в response, а не в request, как пользоваться scrapy можно почитать вот здесь и здесь

А вообще, можно воспользоваться обычным requests

import requests
from pprint import pprint

url = 'https://ru.pinterest.com/resource/BaseSearchResource/get/?source_url=%2Fsearch%2Fpins%2F%3Frs%3Dac%26len%3D2%26q%3Dforest%26eq%3Dfor%26etslf%3D7427&data=%7B%22options%22%3A%7B%22article%22%3A%22%22%2C%22appliedProductFilters%22%3A%22---%22%2C%22price_max%22%3Anull%2C%22price_min%22%3Anull%2C%22query%22%3A%22forest%22%2C%22scope%22%3A%22pins%22%2C%22auto_correction_disabled%22%3A%22%22%2C%22top_pin_id%22%3A%22%22%2C%22filters%22%3A%22%22%2C%22page_size%22%3A%2225%22%7D%2C%22context%22%3A%7B%7D%7D&_=1706559284548'
response = requests.get(url).json()
pprint(response)

Вывод:

{'client_context': {'analysis_ua': {'app_type': 5,
                                    'browser_name': 'Other',
                                    'browser_version': '',
                                    'device': 'Other',
                                    'device_type': None,
                                    'os_name': 'Other',
                                    'os_version': ''},
                    'app_type_detailed': 5,
                    'app_version': '835ac51',
                    'batch_exp': True,
                    'browser_locale': 'en-US',
                    'browser_name': 'Other',
                    'browser_type': None,
                    'browser_version': '',
                    'country': 'RU',
                    'country_from_hostname': 'RU',
                    'country_from_ip': 'RU',
...

Остальная работа на тебе =)
