使用 BeautifulSoup 在 python 中抓取多个页面

我已经设法编写代码来从第一页中抓取数据，现在我不得不在这段代码中编写一个循环来抓取接下来的“n”页。下面是代码

如果有人可以指导/帮助我编写从剩余页面中抓取数据的代码，我将不胜感激。

Thanks!

from bs4 import BeautifulSoup
import requests
import csv


url = requests.get('https://wsc.nmbe.ch/search?sFamily=Salticidae&fMt=begin&sGenus=&gMt=begin&sSpecies=&sMt=begin&multiPurpose=slsid&sMulti=&mMt=contain&searchSpec=s').text

soup = BeautifulSoup(url, 'lxml')

elements = soup.find_all('div', style="border-bottom: 1px solid #C0C0C0; padding: 10px 0;")
#print(elements)

csv_file = open('wsc_scrape.csv', 'w')

csv_writer = csv.writer(csv_file)

csv_writer.writerow(['sp_name', 'species_author', 'status', 'family'])


for element in elements:
    sp_name = element.i.text.strip()
    print(sp_name)



    status = element.find('span', class_ = ['success label', 'error label']).text.strip()
    print(status)




    author_family = element.i.next_sibling.strip().split('|')
    species_author = author_family[0].strip()
    family = author_family[1].strip()
    print(species_author)
    print(family)


    print()

    csv_writer.writerow([sp_name, species_author, status, family])

csv_file.close()

你必须通过page=URL 中的参数并迭代所有页面：

from bs4 import BeautifulSoup
import requests
import csv

csv_file = open('wsc_scrape.csv', 'w', encoding='utf-8')
csv_writer = csv.writer(csv_file)
csv_writer.writerow(['sp_name', 'species_author', 'status', 'family'])

for i in range(151):
    url = requests.get('https://wsc.nmbe.ch/search?page={}&sFamily=Salticidae&fMt=begin&sGenus=&gMt=begin&sSpecies=&sMt=begin&multiPurpose=slsid&sMulti=&mMt=contain&searchSpec=s'.format(i+1)).text
    soup = BeautifulSoup(url, 'lxml')
    elements = soup.find_all('div', style="border-bottom: 1px solid #C0C0C0; padding: 10px 0;")
    for element in elements:
        sp_name = element.i.text.strip()
        print(sp_name)
        status = element.find('span', class_ = ['success label', 'error label']).text.strip()
        print(status)
        author_family = element.i.next_sibling.strip().split('|')
        species_author = author_family[0].strip()
        family = author_family[1].strip()
        print(species_author)
        print(family)
        print()
        csv_writer.writerow([sp_name, species_author, status, family])

csv_file.close()
