Question

我正在尝试提取模型名称和有关模型的任何其他详细信息。当我尝试获取文本，然后我找不到任何特别的，我可以用它来获取数据。

有人知道如何从这些url中获取数据吗？

https://www.audi.de/de/brand/de.html

或https://www.opel.de/auswahlhilfe/modelle.html

我想获得的型号列表，并且可以像价格的任何财产。

到目前为止，我正在尝试使用此功能：

    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信息。这里有专家吗？

如果转到“网络”选项卡，您将获得以下链接，该链接以json格式返回值。您不需要硒。

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

尝试下面的代码。

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：

                           car_name                       car_price

Answer 2

我不确定您是否致力于使用BeautifulSoup，但是您可以使用一些普通的旧硒来解决此问题。

使用您提供的网址https://www.opel.de/auswahlhilfe/modelle.html，这些示例可能会帮助您入门。

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：

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)

Answer 3

使用hits而不是requests ...

urllib.request

Answer 4

您可以从json响应中获取一些数据。只是需要钓鱼从那里可以得到什么：

import requests
from bs4 import BeautifulSoup

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

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)
