Ссылки на оригинальную веб-страницу отсутствуют после разбора с красивым супом

Question

Пожалуйста, извините, если мое объяснение кажется элементарным. Я новичок и в питоне, и в прекрасном супе.

Я пытаюсь извлечь данные со следующего веб-сайта:

https://valor.militarytimes.com/award/5?page=1

Я хочу извлечь ссылки, которые соответствуют каждому из 24 получателей медалей на сайте. Я могу видеть из инспектора Firefox, что все они имеют слово «герой» в своих ссылках. Однако, когда я использую красивый суп для анализа веб-сайта, эти ссылки не отображаются.

Я пытался использовать стандартный анализатор html, а также анализатор html5lib, но ни один из них не показывает ссылки, соответствующие получателям медалей.

page = requests.get('https://valor.militarytimes.com/award/5?page=1')
soup = BeautifulSoup(page.text, "html5lib")
for idx, link in enumerate(soup.find_all('a', href = True)):
        print(link)

Приведенный выше код находит только некоторые ссылки на оригинальном веб-сайте, в частности, нет ссылок, соответствующих получателям медали. Даже при запуске soup.prettify () эти ссылки не отображаются в разобранном тексте.

Я надеюсь иметь простой код, который может извлечь ссылки для 24 получателей медалей на этом сайте.

Answer 1

Если вы хотите избежать использования селена, есть простой способ получить необходимые данные. Страница загружает данные, отправляя почтовые запросы на следующий адрес,

https://valor.militarytimes.com/api/awards/5?page=1

Отправляет ответ json, который затем используется для заполнения страницы с помощью JavaScript. Все, что вам нужно сделать, это отправить тот же запрос, используя python-запросы, а затем получить данные из ответа json.

import requests
r=requests.post('https://valor.militarytimes.com/api/awards/5?page=1')
for item in r.json()['data']:
    name=item['recipient']['name']
    url='https://valor.militarytimes.com/hero/'+str(item['recipient']['id'])
    print(name,url)

Выход:

EUGENE MCCARLEY https://valor.militarytimes.com/hero/500963
TIMOTHY KEENAN https://valor.militarytimes.com/hero/500962

Я также получил имя. Вы можете просто получить ссылку, если вам требуется только это.

Редактировать

Чтобы получить URL-адреса с нескольких страниц, используйте этот код

import requests
list_of_urls=[]
last_page=9 #replace this with your last page
for i in range(1,last_page+1):
    r=requests.post('https://valor.militarytimes.com/api/awards/5?page={}'.format(i))
    for item in r.json()['data']:
        url='https://valor.militarytimes.com/hero/'+str(item['recipient']['id'])
        list_of_urls.append(url)
print(list_of_urls)

Выход:

Answer 2

Вы можете отправлять запросы POST к API, чтобы получить json, содержащий идентификаторы для каждого получателя, которые вы можете объединить на базовый URL, чтобы получить полный URL для каждого получателя. JSON содержит URL последней страницы, чтобы вы могли определить конечную точку для последующего цикла по всем страницам.

import requests
import pandas as pd

baseUrl = 'https://valor.militarytimes.com/hero/'
url = 'https://valor.militarytimes.com/api/awards/5?page=1'
headers = {

  'Accept' : 'application/json, text/plain, */*' ,
  'Referer' : 'https://valor.militarytimes.com/award/5?page=1',
  'User-Agent' : 'Mozilla/5.0'    
}

info = requests.post(url, headers = headers, data = '').json()
urls = [baseUrl + str(item['recipient']['id']) for item in info['data']]   #page 1
linksInfo = info['links']
firstLink = linksInfo['first']
lastLink = linksInfo['last']
lastPage = lastLink.replace('https://valor.militarytimes.com/api/awards/5?page=','')
print('last page = ' + lastPage)
print(urls)

Я проводил тестирование с получением всех результатов и заметил, что вам, возможно, потребуется вернуться назад и повторить попытку.

Вы можете создать дополнительные URL-адреса следующим образом:

if lastPage > 1:
        for page in range(2, lastPage + 1):
            url = 'https://valor.militarytimes.com/api/awards/5?page={}'.format(page)

Answer 3

Вы можете использовать как селеновый вебдрайвер, так и красивый суп

from selenium import webdriver
import time
from bs4 import BeautifulSoup
url = 'https://valor.militarytimes.com/award/5?page=1'
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless')
chrome_options.add_argument('window-size=1920x1080');
driver = webdriver.Chrome(options=chrome_options)
driver.get(url)
time.sleep(10)
page=driver.page_source
soup=BeautifulSoup(page,'lxml')
items = soup.select('a',href=True)
hero=[]
for item in items:
   if 'hero' in item['href']:
       print(item['href'])
       hero.append(item['href'])

print(hero)

Выход:
