Question

이 사이트에서 하나의 웹 페이지에 모든 작물의 가격을 표시하는 코드 아래 만들었다 : http://agmarknet.nic.in/agnew/NationalBEnglish/MarketWiseDailyReport.aspx?ss=1

그러나 나는 단지 웨스트 벵갈에서 Ranaghat (하기 Kalyani)의 가격을 가지고 있었다. 하지만 모든 지역에 대해 eventvalidation 및 eventargument 값을 가져 오려면 모든 지역에 대해 두 값을 모두 얻고 한 페이지에 모든 지역을 표시하는 방법이 있습니까?

우리가 코드 아래 사용하여 동적으로 값을 얻을 수있는 우리의 ViewState 및 EventValidation 값을 작성할 필요가 없습니다 :

<?php 

$debug = 1; 
$fb_page_url = "agmarknet.nic.in/agnew/NationalBEnglish/MarketWiseDailyReport.aspx?ss=1"; 
$cookies = 'cookies.txt';

$uagent = 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/36.0.1985.125 Chrome/36.0.1985.125 Safari/537.36'; 


/** 
    Get __VIEWSTATE & __EVENTVALIDATION 
*/ 
$ch = curl_init($fb_page_url); 
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookies); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_USERAGENT, $uagent); 

$html = curl_exec($ch); 

curl_close($ch); 

preg_match('~<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="(.*?)" />~', $html, $viewstate); 
preg_match('~<input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="(.*?)" />~', $html, $eventValidation); 

$viewstate = $viewstate[1]; 
$eventValidation = $eventValidation[1];

$ch = curl_init(); 

curl_setopt($ch, CURLOPT_URL, $fb_page_url);

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0); 
curl_setopt($ch, CURLOPT_TIMEOUT, 9850);
