在没有 Chrome GUI 的情况下抓取 JS 呈现的站点？

Question

我正在尝试使用 selenium 和 BeautifulSoup 抓取 js 呈现的网站。该代码工作正常，但我需要在没有任何 chrome 的服务器上运行它。我应该在没有 GUI 的情况下对代码进行哪些更改？

下面是当前代码：

from bs4 import BeautifulSoup
import selenium.webdriver as webdriver
import json
from selenium.webdriver.common.keys import Keys

url = 'https://www.bigbasket.com/pc/fruits-vegetables/fresh-vegetables/?nc=nb'

chromepath = "/Users/Nitin/Desktop/Milkbasket/Scraping/chromedriver"
driver = driver = webdriver.Chrome(chromepath)
driver.get(url)

#rest of code for fetching prices

我建议您放弃 Selenium 方法，并使用内置的 urllib 库或requests 库来获取所需的信息。所有产品的信息都可以从返回的 JSON 数据中获取。例如：

import requests
import re

params = {
    "type" : "pc",
    "slug" : "fresh-vegetables",
    "tab_type" : '["all"]',
    "sorted_on" : "popularity",
    "listtype" : "pc",
}

session = requests.Session()

for page in range(1, 10):
    params['page'] = page
    req_vegetables = session.get("https://www.bigbasket.com/product/get-products", params=params)
    json_vegetables = req_vegetables.json()

    print(f'Page {page}')

    for product in json_vegetables['tab_info']['product_map']['all']['prods']:
        print(f"  {product['p_desc']} - {product['sp']} - {product['mrp']}")

这将为您提供以下输出：
