Answer 1

당신은 POST 요청이 http://bepi.mpob.gov.my/admin2/price_local_daily_view3.php 엔드 포인트로 전송됩니다 "보기 가격"버튼을 클릭하면 :

아래 내 코드를 게시했다.

import requests 
from bs4 import BeautifulSoup 


with requests.Session() as session: 
    session.get("http://bepi.mpob.gov.my/index.php/statistics/price/daily.html") 

    response = session.post("http://bepi.mpob.gov.my/admin2/price_local_daily_view3.php", data={ 
     "tahun": "2016", 
     "bulan": "9", 
     "Submit2222": "View Price" 
    }) 
    soup = BeautifulSoup(response.content, 'lxml') 

    table = soup.find("table", id="hor-zebra") 
    headers = [td.get_text() for td in table.find_all("tr")[2].find_all("td")] 
    print(headers) 

테이블의 헤더를 인쇄 : 결과 HTML을이 POST 요청을 시뮬레이션하고 분석

[u'Tarikh', u'September', u'October', u'November', u'December', u'September', u'October', u'November', u'December', u'September', u'October', u'November', u'December']
