如何使用带有Scrapy的admin-ajax.php从网站上抓取数据

Question

I am trying to scrape the reviews about unibet casino on that website : https://casinoplacard.com/unibet-casino-reviews-and-bonuses/

As I did for other sources of reviews I used Scrapy on Python to scrape the reviews with the code below :

class slotRunner_spyder(scrapy.Spider):
count=0

name = "slotRunner_spyder"
start_urls = [

       'https://casinoplacard.com/unibet-casino-reviews-and-bonuses/'
]
def parse(self, response):

    parsed_uri = urlparse(response.url)
    domain = '{uri.scheme}://{uri.netloc}/'.format(uri=parsed_uri)

    for review in response.css('div.rwp-users-reviews > div.rwp-u-review') :
        self.count+=1
        yield {
            'name': review.css('td a::text').extract_first(),
            'date': review.css('td small::text').extract_first(),
            'review': review.css('div.rwp-u-review__content > div.rwp-u-review__comment').extract(),
            'url' : response.url
        }
    print(self.count)

But for that website it does not work. To understand better I have introduced the counter (self.count) and discover that it do only 1 iteration which is not normal...

Then I have spent some tiem studying the DevTools of that website and I have discover that when the page is loaded, a XHR POST request method is done automatically with the URL : https://casinoplacard.com/wp-admin/admin-ajax.php

And by looking into that request I have found the 182 reviews data in :

Preview >> Data >> Reviews

So could you guys please help me understand how it works to catch those data ?

Thank you very much !
