我在LinkedIn上搜索公司数据。为了进入公司页面，需要登录。
我正在使用以下Scrapy Spider：

import scrapy
from scrapy import Spider
from scrapy.http import FormRequest
import time

class BasicLoginSpider(Spider):
    name = 'basic_login_spider'

    def start_requests(self):
       
        login_url = 'https://www.linkedin.com/'
        yield scrapy.Request(login_url, callback=self.login)

    
    def login(self, response):
        # token = response.css("form input[name=csrf_token]::attr(value)").extract_first()
        yield FormRequest.from_response(response,
                                          formdata={
                                                   'password': 'password',
                                                   'username': 'username'},
                                         callback=self.start_scraping)
                                        

    def start_scraping(self, response):

        time.sleep(10)

        self.company_pages = [
        'https://www.linkedin.com/company/nymbus?trk=public_jobs_topcard-org-name',
        'https://www.linkedin.com/company/centraprise?trk=public_jobs_jserp-result_job-search-card-subtitle'
        ]

        company_index_tracker = 0

        first_url = self.company_pages[company_index_tracker]

        yield scrapy.Request(url=first_url, callback=self.parse_response, meta={'company_index_tracker': company_index_tracker})

    def parse_response(self, response):

            headers = {
                'accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,/;q=0.8,application/signed-exchange;v=b3;q=0.9',

                }

            company_index_tracker = response.meta['company_index_tracker']
            print('***************')
            print('****** Scraping page ' + str(company_index_tracker+1) + ' of ' + str(len(self.company_pages)))
            print('***************')

            company_item = {}

            company_item['name'] = response.css('.top-card-layout__entity-info h1::text').get(default='not-found').strip()
            company_item['summary'] = response.css('.top-card-layout__entity-info h4 span::text').get(default='not-found').strip()

            try:
                ## all company details 
                company_details = response.css('.core-section-container__content .mb-2')

                #industry line
                company_industry_line = company_details[1].css('.text-md::text').getall()
                company_item['industry'] = company_industry_line[1].strip()

                #company size line
                company_size_line = company_details[2].css('.text-md::text').getall()
                company_item['size'] = company_size_line[1].strip()

                #company founded
                company_size_line = company_details[5].css('.text-md::text').getall()
                company_item['founded'] = company_size_line[1].strip()
            except IndexError:
                print("Error: Skipped Company - Some details missing")

            yield company_item
            

            company_index_tracker = company_index_tracker + 1

            if company_index_tracker <= (len(self.company_pages)-1):
                next_url = self.company_pages[company_index_tracker]

                yield scrapy.Request(url=next_url, headers = headers, callback=self.parse_response, meta={'company_index_tracker': company_index_tracker})

看看日志，我似乎可以登录，但之后它是999错误和蜘蛛停止：

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 'REQUEST_FINGERPRINTER_IMPLEMENTATION' setting. This is so for backward compatibility reasons, but it will change in a future version of Scrapy.

See the documentation of the 'REQUEST_FINGERPRINTER_IMPLEMENTATION' setting for information on how to handle this deprecation.

有人知道我错过了什么吗？或者我把这个工具用得太远了？

1.登录请求需要发送到URL https://www.linkedin.com/uas/login-submit
1.登录请求其POST参数，根据参数“method='POST'”传递
1.你需要传递更多的参数，使其正确的登录请求。你需要的参数不包括：loginCsrfParam、session_key、session_password、trk、controlId、pageInstance、apfc。
1.调查浏览器中的开发人员面板（网络部分）并获取有关登录请求的更多信息。

  1. 999响应状态等于你代码中修改后的请求一样荒谬：）系统绝对无法识别你的请求
