Scrapy：响应对象为空

I hope you are doing great

I am trying to scrape this website using the scrapy framework. I just need to output the result titles in a csv file. The task seemed easy at first glance, but when using the scrapy shell, I found that the response object is empty. Here is a screenshot:

I said to myself that this website uses AJAX requests. I took a look on developers tab and found that indeed, the website uses AJAX requests. I reverse-engineered it and found the request url for the AJAX call which is this : https://www.tineye.com/search/get_domains/9fdeed61d697e871c74e38116d9c41276bce052e?

here is an image showing what I did

Then I modified my code accordingly, to request the url of the AJAX call, rather than the page itself.

import scrapy
import json

#cpt = 0

class SearchSpider(scrapy.Spider):
    name = "search"
    allowed_domains = ["www.tineye.com"]
    start_urls = ["https://www.tineye.com/search/get_domains/9fdeed61d697e871c74e38116d9c41276bce052e?"]

def parse(self, response):
    #global cpt
    data = json.loads(response.text)
    data = data["domains"]
    for item in data:
        #cpt = cpt + int(item[1])
        yield {
            "link": item[0],
            "times": item[1],
        }

But once again, the response object is empty. What should I do? Thanks in advance
