我想刮一个.net网站，我做这个代码

from scrapy import Selector
from selenium import webdriver
from selenium.webdriver.common.by import By
from webdriver_manager.chrome import ChromeDriverManager

class BoursakuwaitSpider(scrapy.Spider):
    name = 'boursakuwait'
    custom_settings = {
        'FEED_URI': 'second.json',
        'FEED_FORMAT': 'json',
    }
    start_urls = ['https://casierjudiciaire.justice.gov.ma/verification.aspx']

    def parse(self, no_response):
        browser = webdriver.Chrome(executable_path=ChromeDriverManager().install())
        browser.get('https://casierjudiciaire.justice.gov.ma/verification.aspx')
        time.sleep(10)
        response = Selector(text=browser.page_source)

当我使用函数parse时，代码不起作用，但如果我只使用类，就像这样：

import time

import scrapy
from scrapy import Selector
from selenium import webdriver
from selenium.webdriver.common.by import By
from webdriver_manager.chrome import ChromeDriverManager

class BoursakuwaitSpider(scrapy.Spider):
    name = 'boursakuwait'
    custom_settings = {
        'FEED_URI': 'second.json',
        'FEED_FORMAT': 'json',
    }
    start_urls = ['https://casierjudiciaire.justice.gov.ma/verification.aspx']

    browser = webdriver.Chrome(executable_path=ChromeDriverManager().install())
    browser.get('https://casierjudiciaire.justice.gov.ma/verification.aspx')
    time.sleep(10)
    response = Selector(text=browser.page_source)

代码工作正确。但对我来说，我想使用的功能（第一个代码），我不知道哪里是问题。请任何帮助。
