Question

我的代码有什么问题，我尝试获得与https://koleo.pl/rozklad-pkp/krakow-glowny/radom/19-03-2019_10:00/all/EIP-IC--EIC-EIP-IC-KM-REG中相同的内容，但是结果与我想要的有所不同。

import requests
from bs4 import BeautifulSoup

s = requests.Session()
s.headers.update({"User-Agent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) 
AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.186 Safari/537.36'})
response=s.get('https://koleo.pl/rozklad-pkp/krakow-glowny/radom/19-03- 
2019_10:00/all/EIP-IC--EIC-EIP-IC-KM-REG')

soup=BeautifulSoup(response.text,'lxml')
print(soup.prettify())

Answer 1

您必须使用selenium才能获得该动态生成的内容。然后，您可以使用BS解析html。例如，我已经解析了日期：

from bs4 import BeautifulSoup
from selenium import webdriver

driver = webdriver.Firefox()
driver.get('https://koleo.pl/rozklad-pkp/krakow-glowny/radom/19-03-2019_10:00/all/EIP-IC--EIC-EIP-IC-KM-REG')
soup = BeautifulSoup(driver.page_source, 'lxml')
for div in soup.findAll("div", {"class": 'date custom-panel'}):
    date = div.findAll("div", {"class": 'row'})[0].string.strip()
    print(date)

输出：

wtorek, 19 marca
środa, 20 marca

Answer 2

您可以使用请求并传递参数以获取json以获取火车信息和价格。我没有解析所有信息，因为这只是为了告诉您可能。我解析了火车ID，以便能够通过价格信息（通过ID链接到火车信息）进行后续请求

import requests
from bs4 import BeautifulSoup as bs

url = 'https://koleo.pl/pl/connections/?'

headers = {
    'Accept' : 'application/json, text/javascript, */*; q=0.01',
    'Accept-Encoding' : 'gzip, deflate, br',
    'Accept-Language' : 'en-US,en;q=0.9',
    'Connection' : 'keep-alive',
    'Cookie' : '_ga=GA1.2.2048035736.1553000429; _gid=GA1.2.600745193.1553000429; _gat=1; _koleo_session=bkN4dWRrZGx0UnkyZ3hjMWpFNGhiS1I3TzhQMGNyWitvZlZ0QVRUVVVtWUFPMUwxL0hJYWJyYnlGTUdHYXNuL1N6QlhHMHlRZFM3eFZFcjRuK3ZubllmMjdSaU5CMWRBSTFOc1JRc2lDUGV0Y2NtTjRzbzZEd0laZWI1bjJoK1UrYnc5NWNzZzNJdXVtUlpnVE15QnRnPT0tLTc1YzV1Q2xoRHF4VFpWWTdWZDJXUnc9PQ%3D%3D--3b5fe9bb7b0ce5960bc5bd6a00bf405df87f8bd4',
    'Host' : 'koleo.pl',
    'Referer' : 'https://koleo.pl/rozklad-pkp/krakow-glowny/radom/19-03-2019_10:00/all/EIP-IC--EIC-EIP-IC-KM-REG',

    'X-Requested-With' : 'XMLHttpRequest'

}
params = {
    'v' : 'a0dec240d8d016fbfca9b552898aba9c38fc19d5',
    'query[date]' : '19-03-2019 10:00:00',

    'query[brand_ids][]' : '28',
    'query[only_direct]' : 'false',
    'query[only_purchasable]': 'false'
}

with requests.Session() as s:
    data= s.get(url, params = params, headers = headers).json()
    print(data)
    priceUrl = 'https://koleo.pl/pl/prices/{}?v=a0dec240d8d016fbfca9b552898aba9c38fc19d5'
    for item in data['connections']:
        r = s.get(priceUrl.format(item['id'])).json()
        print(r)

按要求报废
