我正在構建一個機器人來從他們的商店頁面檢查各種 Ubiquiti Unifi 設備的庫存（嘿，這些東西正在快速消失），我需要一些幫助。我整天都在尋找這樣的東西，但我在這里看到的東西都沒有奏效。
我正在使用以下代碼訪問 UI.com 商店 ( https://store.ui.com/ )。他們非常方便地在每個頁面的標題中都有庫存產品資訊，我正在使用 selenium 獲取主頁并需要訪問：
<script data-ot-ignore type="text/javascript">
window.APP_DATA = {

現在，我對 javascript 沒有太多經驗，但看起來我感興趣的資料基本上是另一個物件內的 javascript 物件陣列？（“cartAccessories”的 [{}] 結構，一切都在其中。）源代碼的元素檢查給了我“/html/head/script[33]”作為腳本的 XPATH ......我想。似乎幾乎每次都回傳不同的資料。
我正在使用以下基本代碼來獲取頁面：
from selenium import webdriver
from selenium.webdriver.common.by import By
import time
urlpage = 'https://store.ui.com/'
print(urlpage)
driver = webdriver.Firefox()
# get web page
driver.get(urlpage)
time.sleep(1)
print("Getting Results.")
results = driver.find_element(By.XPATH, "/html/head/script[33]")
html = results.get_attribute('innerHTML')
print(f"The results are: {html}")
driver.quit()
但這似乎不對。我想將“cartAccessories”資訊放入 python 串列中，以便我可以處理它。訪問此資訊的最佳方式是什么？我對這一切都錯了嗎？
uj5u.com熱心網友回復：
您可以使用正則運算式來獲取包含感興趣陣列的總體 JavaScript 物件，然后將其傳遞給 hjson 以處理未參考的鍵。最后，提取cartAccessories專案并用它做你想做的事。
import requests, re, hjson
r = requests.get('https://store.ui.com/')
data =hjson.loads(re.search(r'window.APP_DATA = (.*?)<', r.text, re.S).group(1))
print(data['cartAccessories'])
