问题描述
我正在尝试登录MCA门户（POST URL：
任何想法都丢失了吗？
解决方案
该站点进行重定向，因此您需要添加
CURLOPT_FOLLOWLOCATION => 1
到您的期权数组。如果对cURL有疑问，请尝试
$ status = curl_getinfo（$ curl）;。
echo json_encode（$ status，JSON_PRETTY_PRINT）;
给予：
{
url： http：\ / \ / www.mca.gov.in\ / mcafoportal\ / loginValidateUser.do？userNamedenc = hGJfsdnk％601t& passwordenc = 675894242fa9c66939d9fcf4d5c39d1830f4ddb9& ; accessCode = -825374456，

local_ip： 192.168.1.54，

}
如您所见，您得到了 302 重定向状态，但 redirect_count 为 0 。添加选项后，我得到：
{
url： http：\ / \ / www.mca.gov.in\ / mcafoportal\ / login.do，
content_type： text\ / html; charset = ISO-8859-1，

}
EDIT url编码请求参数，并按照重定向进行操作
$ str = urlencode（ userNamedenc = hGJfsdnk％601t& passwordenc = 675894242fa9c66939d9fcf4d5c39d1830f4ddb9& accessCode = -825374456）;
curl_setopt_array（
$ curl，array（
CURLOPT_URL => http://www.mca.gov.in/mcafoportal/loginValidateUser.do，//<-删除的参数这里
CURLOPT_RETURNTRANSFER => true，
CURLOPT_ENCODING =>，
CURLOPT_FOLLOWLOCATION => 1，
CURLOPT_MAXREDIRS => 10，
CURLOPT_TIMEOUT => 30，
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1，
CURLOPT_CUSTOMREQUEST => POST，
CURLOPT_POSTFIELDS => $ str，//<--在此添加
CURLOPT_HTTPHEADER => ; array（

）
）;
I am trying to login to MCA portal ( POST URL : http://www.mca.gov.in/mcafoportal/loginValidateUser.do )
I tried logging in with POSTMAN app on Google Chrome which works fine. However, it doesnt work either in PHP/Python. I am not able to login through PHP/Python
Here is the PHP Code :
$url="http://www.mca.gov.in/mcafoportal/loginValidateUser.do";
$post_fields = array();
$post_fields['userNamedenc']='hGJfsdnk`1t';
$post_fields['passwordenc']='675894242fa9c66939d9fcf4d5c39d1830f4ddb9';
$post_fields['accessCode'] = ""
$str = call_post_mca($url, $post_fields);
$str = str_replace(" ","",$str);
$dom = new DOMDocument();
$dom->loadHTML($str);
$xpath = new DOMXPath($dom);
$input_id = '//input[@id="login_accessCode"]/@value';
$input_val = $xpath->query($input_id)->item(0);
$input_val1 = $input_val->nodeValue;
$url="http://www.mca.gov.in/mcafoportal/loginValidateUser.do";
$post_fields['userNamedenc']='hGJfsdnk`1t';
$post_fields['passwordenc']='675894242fa9c66939d9fcf4d5c39d1830f4ddb9';
$post_fields['accessCode'] = $input_val1; //New Accesscode
function call_post_mca($url, $params)
{
#$user_agent = getRandomUserAgent();
$user_agent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36";
$str = "";
foreach($params as $key=>$value)
{
$str = $str . "$key=$value" . "&";
}
$postData = rtrim($str, "&");
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_HEADER, false);
#curl_setopt($ch, CURLOPT_CAINFO, DOC_ROOT . '/includes/cacert.pem');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt($ch,CURLOPT_USERAGENT, $user_agent);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($ch, CURLOPT_REFERER, $url);
$cookie= DOC_ROOT . "/cookie.txt";
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookie);
$output=curl_exec($ch);
curl_close($ch);
return $output;
}
Any idea what is missing ?
解决方案
The site does a redirect, so you need to add
CURLOPT_FOLLOWLOCATION => 1
to your options array. When in doubt with cURL, try
$status = curl_getinfo($curl);
echo json_encode($status, JSON_PRETTY_PRINT);
giving :
{
"url": "http:\/\/www.mca.gov.in\/mcafoportal\/loginValidateUser.do?userNamedenc=hGJfsdnk%601t&passwordenc=675894242fa9c66939d9fcf4d5c39d1830f4ddb9&accessCode=-825374456",
"content_type": "text\/plain",
"http_code": 302,
"header_size": 1560,
"request_size": 245,
"filetime": -1,
"ssl_verify_result": 0,
"redirect_count": 0,
"total_time": 1.298891,
"namelookup_time": 0.526375,
"connect_time": 0.999786,
"pretransfer_time": 0.999844,
"size_upload": 0,
"size_download": 0,
"speed_download": 0,
"speed_upload": 0,
"download_content_length": 0,
"upload_content_length": -1,
"starttransfer_time": 1.298875,
"redirect_time": 0,
"redirect_url": "http:\/\/www.mca.gov.in\/mcafoportal\/login.do",
"primary_ip": "115.114.108.120",
"certinfo": [],
"primary_port": 80,
"local_ip": "192.168.1.54",
"local_port": 62524
}
As you can see, you got a 302 redirect status, but a redirect_count was 0. After adding the option, i get:
{
"url": "http:\/\/www.mca.gov.in\/mcafoportal\/login.do",
"content_type": "text\/html;charset=ISO-8859-1",
"http_code": 200,
"header_size": 3131,
"request_size": 376,
"filetime": -1,
"ssl_verify_result": 0,
"redirect_count": 1,
"total_time": 2.383609,
"namelookup_time": 1.7e-5,
"connect_time": 1.7e-5,
"pretransfer_time": 4.4e-5,
"size_upload": 0,
"size_download": 42380,
"speed_download": 17779,
"speed_upload": 0,
"download_content_length": 42380,
"upload_content_length": -1,
"starttransfer_time": 0.30734,
"redirect_time": 0.915858,
"redirect_url": "",
"primary_ip": "14.140.191.120",
"certinfo": [],
"primary_port": 80,
"local_ip": "192.168.1.54",
"local_port": 62642
}
EDIT url encode the request parameters , and follow redirects
$str = urlencode("userNamedenc=hGJfsdnk%601t&passwordenc=675894242fa9c66939d9fcf4d5c39d1830f4ddb9&accessCode=-825374456");
curl_setopt_array(
$curl , array (
CURLOPT_URL => "http://www.mca.gov.in/mcafoportal/loginValidateUser.do" , // <- removed parameters here
CURLOPT_RETURNTRANSFER => true ,
CURLOPT_ENCODING => "" ,
CURLOPT_FOLLOWLOCATION => 1 ,
CURLOPT_MAXREDIRS => 10 ,
CURLOPT_TIMEOUT => 30 ,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1 ,
CURLOPT_CUSTOMREQUEST => "POST" ,
CURLOPT_POSTFIELDS => $str, // <- added this here
CURLOPT_HTTPHEADER => array (
"cache-control: no-cache"
) ,
)
);
