我试图提取模型名称和有关模型的任何其他细节。当我试图获取文本时，我找不到任何可以用于获取数据的特殊内容

有人知道如何从这些URL获取数据吗

或

我想得到的模型和任何财产的清单，这是像价格

到目前为止，我尝试使用以下方法：

    from selenium import webdriver
    from bs4 import BeautifulSoup
    import pandas as pd
    from urllib.request import urlopen

    url = "https://www.opel.de/auswahlhilfe/modelle.html"
    html = urlopen(url)
    text = soup.get_text()

但是我没有得到任何有用的东西。。这里有专家吗？

我不确定您是否承诺使用BeautifulSoup，但您可以用一些简单的旧硒解决这个问题

使用您提供的URL，这些示例可以帮助您开始

from selenium import webdriver
from time import sleep
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

# start the driver
driver = webdriver.Chrome()

# navigate to the URL
driver.get("https://www.opel.de/auswahlhilfe/modelle.html")

# invoke WebDriverWait to wait for page to load
# get the model names
model_names = WebDriverWait(driver, 10).until(
        EC.presence_of_all_elements_located((By.XPATH, "//a/div/div/div/span[contains(@class, 'q-carline')]")))

for model in model_names:
    print(model.text)

要获取价格列表，请执行以下操作：

prices = driver.find_elements_by_xpath("//a/div/div/div/span[contains(@class, 'q-price')]/span[contains(@class, 'q-value')]");

for price in prices:
    print(price.text)

使用

请求

而不是

urllib.request

import requests
from bs4 import BeautifulSoup

url = "https://www.opel.de/auswahlhilfe/modelle.html"
r = requests.get(url)
soup = BeautifulSoup(r.text, 'html.parser')
text = soup.get_text()
print(text)

如果您转到网络选项卡，您将获得以下链接，该链接以json格式返回值。你不需要硒来做到这一点

https://www.opel.de/apps/atomic/getVehicleTeasers.path=L2NvbnRlbnQvb3BlbC93b3JsZHdpZGUvZ2VybWFueS9kZS9pbmRleC9iYXNlYmFsbC1jYXJkcy9iYmMtY29sbGVjdGlvbnMvdmVoaWNsZXMtb25seS1jb2xsZWN0aW9uPuGlIfE.feefoEnabled=false.expandingMenuEnabled=false.json

试试下面的代码

from bs4 import BeautifulSoup
import requests
import pandas as pd
url='https://www.opel.de/apps/atomic/getVehicleTeasers.path=L2NvbnRlbnQvb3BlbC93b3JsZHdpZGUvZ2VybWFueS9kZS9pbmRleC9iYXNlYmFsbC1jYXJkcy9iYmMtY29sbGVjdGlvbnMvdmVoaWNsZXMtb25seS1jb2xsZWN0aW9uPuGlIfE.feefoEnabled=false.expandingMenuEnabled=false.json'
rs=requests.get(url).json()
html=''.join(rs['bbcTeaser'])
soup=BeautifulSoup(html,'html.parser')
car_name=[]
car_price=[]
for name, price in zip(soup.select('.q-carline'),soup.select('.q-value')):
    car_name.append(name.text)
    car_price.append(price.text)

df = pd.DataFrame({"car_name":car_name,"car_price":car_price})
print(df)

输出：

jsonData = requests.get(url).json()['bbcTeaser']

for each in jsonData:
    soup = BeautifulSoup(each)

    carline = soup.find('span', {'class':'q-carline'}).text
    price = soup.find('span', {'class':'q-value'}).text

    print (carline, price)

谢谢你的回答。是否因为使用了“驱动程序”而使用了其他库？

未定义名称“驱动程序”

只是出现错误。驱动程序是Selenium Webdriver。你必须首先启动一个驱动程序。更新了我的代码示例。谢谢。但仍然出现异常错误：

WebDriverException:消息：“chromedriver”可执行文件需要位于路径中。请看https://sites.google.com/a/chromium.org/chromedriver/home

您需要完全按照错误消息的指示执行操作——将chromedriver.exe添加到Path环境变量中。有大量的指南和教程向您展示如何做到这一点。这里有一个：谢谢@Moshe，但我如何生成列表？我正在获取文本及其干净的文本，但不确定如何从中创建模型列表…@MuhammadSalmanShahid请参阅KunduK的答案。。。他完成了工作！太神了这就是我想要的：）谢谢@KunduK@KunduK我试图在frm网络中找到这个json url，但找不到那个特定的url。你能再解释一下吗？一旦你进入网络标签，点击XHR标签，然后点击ctlr+R，你就会看到一个链接，当你点击response标签时，它会以json的形式返回数据。
