这是我的代码

titles = []
prices = []
super_area = []
bhk = []
move = []
for post in item:
    title = post.find(id='srp_tuple_property_title').get_text().strip()
    price = post.find(id='srp_tuple_price').get_text().strip()
    area = post.find(id='srp_tuple_primary_area').get_text().strip()
    moves = post.find(class_='badges__secondaryLargeSubtle').get_text().strip()
    bed = post.find(id='srp_tuple_bedroom').get_text().strip()
    bhk.append(bed)
    move.append(moves)
    super_area.append(area)
    prices.append(price)
    titles.append(title)

尝试使用基础API。过滤后检查实际的API调用将为您提供正确的URL。

import requests

url = "https://www.99acres.com/api-aggregator/project/searchWidget?area_unit=1&platform=DESKTOP&moduleName=GRAILS_SRP&workflow=GRAILS_SRP&city=45&preference=S&res_com=R&page=1&page_size=10&isCrossSell=false"
data = requests.get(url=url).json()
print(data['newProjects'][1]['propTypeStr'])
# 2 BHK Apartment

过滤将更改URL的参数，例如：

https://www.99acres.com/api-aggregator/srp/search?bedroom_num=3&budget_min=136&locality_array=6046%2C6038&area_min=1900&area_unit=1&localityNameMap=%5Bobject%20Object%5D&platform=DESKTOP&moduleName=GRAILS_SRP&workflow=GRAILS_SRP&page_size=30&page=1&city=45&preference=S&res_com=R&seoUrlType=DEFAULT

这可以用urllib来分解：

from urllib import parse

url = "https://www.99acres.com/api-aggregator/srp/search?bedroom_num=3&budget_min=136&locality_array=6046%2C6038&area_min=1900&area_unit=1&localityNameMap=%5Bobject%20Object%5D&platform=DESKTOP&moduleName=GRAILS_SRP&workflow=GRAILS_SRP&page_size=30&page=1&city=45&preference=S&res_com=R&seoUrlType=DEFAULT"
parse.parse_qs(parse.urlparse(url).query)
# {'bedroom_num': ['3'],
#  'budget_min': ['136'],
#  'locality_array': ['6046,6038'],
#  'area_min': ['1900'],
#  'area_unit': ['1'],
#  'localityNameMap': ['[object Object]'],
#  'platform': ['DESKTOP'],
#  'moduleName': ['GRAILS_SRP'],
#  'workflow': ['GRAILS_SRP'],
#  'page_size': ['30'],
#  'page': ['1'],
#  'city': ['45'],
#  'preference': ['S'],
#  'res_com': ['R'],
#  'seoUrlType': ['DEFAULT']}
