BeautifulSoup - json from JS

Question

BeautilfulSoup을 가지고 놀고있어 JS 요소 내에서 특정 json 문자열을 얻는 방법을 찾고 있습니다.

<script>window.pinball = window.pinball || []; 
window.pinball.push(['add', {"srp_cleanup":"inactive","book_visit":"inactive","my_visits":"inactive"}]); 
window.Rent = window.Rent || {}; 
window.Rent.zutron = {"error_div":".js-generic-error","host":"rent","user_type":null,"zid":null,"origin":null,"provider":null}; 
window.Rent.book_visit = {"book_visit_host":"http://bookavisit.prod.services.rentpath.com"} 
window.Rent.tagging = {"tealium":{"env":"prod","profile":"tealium.rent.com","account":"rentpath"}}; 
window.Rent.realm = "rent"; 
window.Rent.data = {"floorplans":{"1159255":{"availability":"1 Unit Available","availability_class":"floorplan-available-now","unitstyle":"aa1- 1 Bed/1

내가 BeautifulSoup로를 통해 JS를 당길 수 있었다 나는 window.Rent.data 키에 해당하는 JSON 문자열을 찾고 있어요 :

다음은 JS입니다.

re에 의존하지 않고도이 작업을 수행 할 수 있습니까?

Answer 1

캡처 그룹이 인 정규 표현식 패턴을 사용하는 것이 좋습니다. 그런 다음이 정규 표현식을 사용하여 텍스트로 script 요소를 찾은 다음 스크립트 자체에서 하위 문자열을 추출합니다. 그런 다음, 당신은 파이썬 객체로 JSON 문자열을로드 json.loads()을 사용할 수 있습니다 :

는

import json 
import re 

from bs4 import BeautifulSoup 

data = """ 
your HTML here""" 

soup = BeautifulSoup(data, "html.parser") 

pattern = re.compile(r"window.Rent.data\s+=\s+(\{.*?\});\n") 
script = soup.find("script", text=pattern) 

data = pattern.search(script.text).group(1) 
data = json.loads(data) 
print(data) 

또한 다른 방법이는 - 자바 스크립트 파서-I've experimented with slimit on StackOverflow a couple of times, 그것을 확인하시기 바랍니다.
