我正在努力学习用Python进行刮取,在本例中,我的想法是制作一个从网页获取数据的工具。我有一个问题,建议“for”遍历页面并收集每个框(项目)的数据,因为它们是:
这不是一项任务,这是我自己的倡议,但我没有向前迈进,为此我感谢你的帮助
以下是我对代码的理解:
from bs4 import BeautifulSoup
import requests
URL_BASE = "https://www.milanuncios.com/ofertas-de-empleo-en-madrid/?dias=3&demanda=n&pagina="
MAX_PAGES = 2
counter = 0
for i in range(0, MAX_PAGES):
#Building the URL
if i > 0:
url = "%s%d" % (URL_BASE, i)
else:
url = URL_BASE
#We make the request to the web
req = requests.get(url)
#We check that the request returns a Status Code = 200
statusCode = req.status_code
if statusCode == 200:
#We pass the HTML content of the web to a BeautifulSoup () object
html = BeautifulSoup(req.text, "html.parser")
#We get all the divs where the inputs are
entradas_IDoffer = html.find_all('div', {'class': 'aditem-header'})
#We go through all the inputs and extract info
for entrada1 in entradas_IDoffer:
#THIS ARE SOME ATTEMPS
#Title = entrada.find('div', {'class': 'aditem-detail-title'}).getText()
#location = entrada.find('div', {'class': 'list-location-region'}).getText()
#content = entrada.find('div', {'class': 'tx'}).getText()
#phone = entrada.find('div', {'class': 'telefonos'}).getText()
#Offer Title
entradas_Title = html.find_all('div', {'class': 'aditem-detail'})
for entrada2 in entradas_Title:
counter += 1
Title = entrada2.find('a', {'class': 'aditem-detail-title'}).getText()
counter += 1
IDoffer = entrada1.find('div', {'class': 'x5'}).getText()
#Location
#entradas_location = html.find_all('div', {'class': 'aditem-detail'})
#for entrada4 in entradas_location:
# counter += 1
# location = entrada4.find('div', {'class': 'list-location-region'}).getText()
#Offer content
#entradas_content = html.find_all('div', {'class': 'aditem-detail'})
#for entrada3 in entradas_content:
# counter += 1
# content = entrada3.find('div', {'class': 'tx'}).getText()
print("%d - %s \n%s\n%s" % (counter, IDoffer.strip(),url,Title))
else:
try:
r = requests.head(req)
print(r.status_code)
except requests.ConnectionError:
print("failed to connect")
break
#If the page no longer exists and it gives me a 400
正确的陷阱
标题位于“a”标签下,而不是“div”
对于其他数据,请执行此操作
他们可能正在使用javascript加载电话号码,所以您可能无法使用bs4获取该号码,您可以使用selenium获取该号码
您编写了非常长的代码来循环多个页面,只需使用range来遍历第1页和第2页。将url放入格式化字符串中
