刮页不会返回正文

Question

我正在尝试获取此url的内容：https://www.alljobs.co.il/SearchResultsGuest.aspx?page=1&position=&type=&freetxt=&city=&region=

但这一反应似乎不包含任何主体。不过脑子里有个剧本。这就是我尝试过的（从浏览器中添加标题，该页面可以很好地加载）

import scrapy


class TestSpider(scrapy.Spider):

    name = 'testspider'
    headers = {
        "Host": "www.alljobs.co.il",
        "Sec-Fetch-Site": "same-origin",
        "Sec-Fetch-Mode": "navigate",
        "Referer": "https://www.alljobs.co.il/SearchResultsGuest.aspx?page=1&position=&type=&freetxt=&city=&region=",
        "Accept-Encoding": "gzip, deflate, br",
        "Accept-Language": "en-US,en;q=0.9,ne;q=0.8,it;q=0.7,mt;q=0.6",
        "User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.117 Safari/537.36"
    }

    def start_requests(self):
        url = 'https://www.alljobs.co.il/SearchResultsGuest.aspx?page=1&position=&type=&freetxt=&city=&region='
        yield scrapy.Request(url=url, callback=self.parse, headers=self.headers)

    def parse(self, response):
        print(response.status, 'open-board' in response.body)

输出为：

硒也是同样的问题

from selenium import webdriver
driver = webdriver.Chrome(executable_path=r'/path_to_/chromedriver')
url = "https://www.alljobs.co.il/SearchResultsGuest.aspx?page=1&position=&type=&freetxt=&city=&region="
driver.get(url)
html = driver.page_source
print("works= {}".format("open-board" in html))

它显示works= False。我不知道这为什么不起作用

任何帮助都将不胜感激。谢谢
